Believe These Energy Efficiency Myths? Top 5 Busted

Letters Spelling out MYTHS

More and more people are trying to reduce their carbon footprints, improving the environment for future generations. As trusted southeast Michigan heating, cooling, and plumbing professionals, we know that many homeowners have heard and read little pieces of “advice” here and there that they believe to be fact. Some of these energy efficiencies “tips” are energy efficiency myths, and will end up costing you more in energy costs!

Energy Efficiency Myths

Most of the energy efficiency myths we will talk about below relate to leaving appliances, lights, and electronics on, rather than turning them off when not in use. You may be surprised to learn that what you have been doing is all wrong!

Energy is saved by using screensavers on your computer

Myth! While it doesn’t cost you more if you do use one, a screen saver does nothing to save energy. A screen uses the same amount of energy whether it is left on a website or spreadsheet, or with the screensaver on. If you need to leave your computer for a few minutes, just turn it off – that’s the only real way you will save energy.

Leaving the lights on saves more energy than turning them on and off.

Again, this is a myth! While this piece of advice applied mostly to fluorescent tube lighting, even with the energy-saving light bulbs available today it is more energy efficient to turn the lights off when you leave a room. Get into the habit, and it will save you a bundle. Industrial or commercial businesses may want to consider lighting that works through motion detection to eliminate the need for turning lights on and off.

Cooling a room costs less when you leave the ceiling fan on

This is a big myth – ceiling fans only cool the people who are in a room by circulating the air around, the actual room temperature doesn’t change at all. If a room is not occupied and you leave the ceiling fan on, it is a total – and costly – waste of energy. Air conditioning is the only “true” way to lower the temperature in a room. However, you don’t want to run your air conditioning unless you need it either, because it uses energy!

It costs more in energy to heat a cold building or space

Think it’s better to leave a boiler on overnight, so that the building doesn’t get as cold, and thus takes less time to heat up? False! The fact is a boiler works equally as hard whether maintaining a temperature or warming up to the desired temperature, so when you don’t need it, flip the switch to off.

You waste energy and “wear out” light bulbs and computers by repeatedly switching on and off

Not true! While older computers were more susceptible to damage caused by everyday wear and tear, today’s modern computers are tougher and more durable. If you are forgetful, utilize the ‘sleep’ and ‘hibernate’ power saving modes to avoid wasting energy. Turning lights on and off has no impact on their lifespan, as they are designed for this type of use. The takeaway? Turn lights and computers off when you’re not using them.

Maybe some of these myths got started by people who are simply just too lazy to turn things off, or perhaps at some point they were believed to be true. Regardless, there is no advantage energy-wise to leaving electronics, lights, boilers, or ceiling fans on when not in use!

Ann Arbor Homeowners Can Lower Energy Costs With These Simple Tips

Piggy Bank - Save on utilities!

Today, many southeast Michigan homeowners are looking for ways to reduce energy costs and consumption, primarily due to increasing fuel prices and increased environmental awareness.  The fact is, accomplishing these goals is fairly easy with just a few small changes and a little effort.

At Haley Mechanical, we’re happy to provide you with a few tips to help you save on both energy costs and usage:

Consider a programmable thermostat.  This “smart” thermostat makes it possible to keep your home comfortable while saving on energy use.  Depending on your family’s schedule, you can pre-program temperature settings for night time, while you are away during the daytime hours, or even while on vacation.

Don’t skip seasonal maintenance.  HVAC equipment that is running smoothly is more efficient, thereby less costly to run.  You may not be aware that cooling and heating your home accounts for about 50% of the energy you use each month!  Consider scheduling preventive maintenance services in spring and fall, just prior to hot summer months and the cold winter season.

Change the filter regularly.  We know – you’ve heard it time and time again, but do you do it?  Filters collect dust, dirt, and other debris, making your HVAC system work harder to keep your home comfortable, which means increased cost.  Not only that, a clogged filter can lead to a buildup of dust and dirt within the components of your heating/cooling system, resulting in damage or unnecessary wear and tear.  Change it regularly, especially during summer and winter months.

Check the ducts for leaks, and seal any cracks or holes.  Because the ductwork is something you don’t see often, it’s easy to forget about it.  Check your ducts for leaks, which often occurs in areas where cracks or breaks exist.  Tape any visible leaks using a metal-backed or duct mastic tape instead of duct tape, which doesn’t hold up well.  Also consider additional insulation on ducts located in a garage, attic, or other unconditioned space.

Replace older or inefficient HVAC equipment with Energy Star qualified equipment.  A heating/cooling system that’s older than 10 years may not be efficient.  If your current system isn’t operating efficiently or is getting on up there in age, consider replacing it with an Energy Star qualified system.  These products are proven to help lower energy costs, and consume less energy.

Most important of all, choose your southeast Michigan HVAC contractor wisely!  It is critical that your air conditioning and heating equipment is properly sized for your home and installed correctly.  Improper installation of your HVAC system could cost you more in terms of energy usage – up to 30% more.

Learn more about how you can lower energy costs and consumption in your home this summer.  Call Haley Mechanical today, and let our experts help you enjoy a comfortable home that costs less in terms of heating/cooling costs!

Prepare Your Greater Ann Arbor Home for Summer with These Tips

Girl Swimming in Pool During the Summer

Recent temperatures have been incredibly warm, almost brutal for those in Southeast Michigan. We always look forward to summer months – but those increased energy bills, not so much. We have a few tips to help you enjoy a comfortable home this summer while keeping energy costs down.

Upgrade to a programmable thermostat

No more turning the temperature up or down manually. You do not want to come home to a hot house after work, but why cool an empty space? A programmable thermostat lets you program the thermostat to cool your home just before your family comes in at the end of the day.

Have your AC cleaned and inspected

A dirty air conditioner that hasn’t been properly maintained is less efficient and more prone to break completely down on you. Decreased efficiency means reduced comfort, and higher energy bills. Have a qualified technician inspect and clean your system, and enjoy greater comfort all summer long.

Consider an insulation upgrade

If your home lacks sufficient insulation, it impacts comfort. Insulation does not only keep cold air out in winter months; it also keeps out heat/humidity during summer months. Having extra insulation blown into the walls and/or around windows and doors is an easy process that can save you big time.

Install ceiling fans and awnings

While ceiling fans will not lower the temperature in the room you are in, they will circulate the cool air which makes it feel much cooler to your skin. You can set the temperature up a couple of degrees higher, and not notice a difference – other than lower energy costs.

Awnings placed above windows are another way to keep the hot direct sunlight out, without darkening your home or having to repeatedly open/close blinds, shades, or curtains. They also add to the exterior appeal of your home!

Ventilate the attic

When the attic lacks adequate ventilation, the hot air that rises from the rooms in your home gets trapped. Temperatures in the attic can reach as much as 150 degrees on super hot days, so you know that “holding in” of heat makes your home feel like an oven. Hot air can escape from the attic by simply installing vents or attic fans.

At Haley Mechanical, we want to help Ann Arbor and Dexter homeowners enjoy a cool, comfortable home without dreading those huge monthly utility bills. For more tips or to schedule an inspection/cleaning of your HVAC system, give us a call today!

Is Your HVAC System Unhealthy? Indications Trouble Could be Lurking

Woman relaxing in her comfortable home

Every Ann Arbor homeowner knows that without an HVAC system, you would be very uncomfortable during summer and winter months! While it is the most important system in your home, it could potentially put your family in danger. Could trouble be lurking with your heating & cooling system? Here are a few indications it may be time to call in our Southeast Michigan furnace repair experts.

Smell that distinct electrical burning odor? When you notice this smell, it could mean your system is overheating, or that wiring is damaged. Even when you do not think it is serious, never ignore this smell as it could indicate damage or burning in the system, even resulting in a fire if the situation goes unchecked.

Is your nose detecting a sulfur or a rotten egg smell? This could indicate a natural gas leak which is extremely dangerous. Remove yourself and your family from your home immediately, and never try to figure out what the problem is yourself. Call the professionals, as a gas leak could result in a fire or explosion.

Slight burning odor when running your furnace. Upon switching the furnace on for the first time during the heating season, a slight burning smell is not unusual. This is an indication your furnace is burning oil, which may be leaking near the system’s heat output. If you notice a burning odor, switch the furnace off and shut the oil off before contacting our HVAC technicians to diagnose the issue.

Musty or moldy smell caught your attention? Bacteria may be growing when you notice an odor that’s musty, earthy, or moldy. Cooling systems can be the perfect breeding ground for mold due to the fact condensation often builds up on the inside. If this condensation or moisture travels to the ductwork, you may notice a musty smell – and mold can be a health risk. The solution? Have your ductwork and HVAC system cleaned by professionals.

Inspecting your HVAC system occasionally is recommended, as you discover your system is leaking if you notice a puddle beginning to form, which could result in mold or even a slipping hazard. Determine where the leak originates if possible, then contact our HVAC experts.

Any time you notice the above symptoms, it is a good idea to contact our SE Michigan HVAC professionals. At Haley Mechanical, we help Ann Arbor, and Dexter homeowners get small issues under control before they become costly or more dangerous problems! Give us a call today, and enjoy peace of mind.

A Brief History of Residential Heating

After Learning the History of Home Heating, You’ll Be Thankful for Today’s Home Comfort Systems

When cold weather strikes in southeast Michigan, all we have to do to stay warm and toasty is adjust the thermostat – but it wasn’t always that easy! In fact, staying warm prior to the invention of the home furnace required a lot of effort and hard work. Be thankful that you don’t have to gather wood (unless you just enjoy a fire) or coal today, and that all it takes is a flick of the wrist to enjoy a warm home!

Here’s the history of home heating through the ages:

Ancient Greeks and Roman Engineers

In the early days, enclosed wood-burning was the method used to heat homes. While it is believed central heating was invented by the ancient Greeks, Roman engineers invented the hypocaust system and are given credit for central heating advances. According to the BBC, homes, villas, and other buildings in the Roman Empire were heated using hypocaust systems, which essentially conducted furnace-heated air within the walls and under floors of these buildings.

German Monks Resurrect Central Heating

German monks relied on a simpler system in early medieval times; this system involved a furnace room which pumped warm air into their abbeys through under-floor channels. In the 13th century, the Roman hypocaust system was revived by Cistercian monks who used a combination of indoor wood burning furnaces and river diversions to provide heat according to Wikipedia.

Russians and Swedes Design Heating Systems Based on Water and Steam

The early 1700s brought about a different way of heating greenhouses and warming palaces, as the Russians and Swedes designed central heating systems which used water to distribute heat. In 1832, U.S. born Angier March Perkins invented a steam heating system, doing the majority of his work in the UK. The steam heating system was developed primarily for the Governor of the Bank of England who desired the ability to grow grapes in the cold climate.

Now Enter the Radiator and Furnace

Franz San Galli, a Polish-born Russian, changed the face of central heating forever in the 1850s when the heating radiator was born. By the late 1800s, many American homes enjoyed heat generated by cast iron radiators which relied on coal-fired boilers usually located in a basement which heated various rooms of a home via steam or hot water directed to individual room radiators.

Eventually, Dave Lennox – a name you’re likely familiar with – invented the first riveted-steel coal furnace in 1885. Since that time, the Iowa-based Lennox manufacturing company has evolved into Lennox International, a recognized brand around the world for heat and air systems.

Haley Mechanical takes pride in offering our southeast Michigan customers in Ypsilanti, Ann Arbor, Dexter, and surrounding communities the highest quality home comfort systems. When it comes to keeping your home toasty and warm this winter, call the experts! We offer high efficiency, environmentally friendly home comfort solutions.

Batten Down the Attic Hatch to Prevent Wasted Energy Dollars

House Attic in Ann Arbor Michigan

If you’re an Ann Arbor area homeowner with an attic hatch, some of your energy dollars may be going right up into your attic if the hatch isn’t insulated and sealed. Now that the Christmas decorations have been put away, it’s a good time to make your attic hatch airtight, keeping your home more comfortable while saving you money.

If your attic space is unfinished and/or not insulated, even more energy is being lost; heat rises, and when it escapes around your attic hatch and then out of the attic itself, you will spend more on energy and find it more difficult to keep your home warm.

So, how can you check to see if your attic hatch is sucking energy from your home, and how much? Easy.

  • Turn off any sources in your home which will create air drafts, such as furnaces or air conditioners.
  • Using a smoke pencil or “smoke puffer” like professionals use, or an incense stick that has been lighted and produces a thin stream of smoke, hold it near the attic hatch. As you observe you will be able to tell if you have an air leak, as the smoke will either bend toward the leak if air is entering the attic or away from the attic if air is coming out.

Between finishing your attic and closing the hatch, you can save as much as 30% on heating bills!

If you discover air leaks around your attic hatch, what to do? If you’re a do-it-yourselfer, consider applying foam tape or weatherstripping around edges; there are also insulated hatch covers available at many home supply stores. Additionally, you may want to attach manufactured fabric housing to the stairs to further block air leakage.

If your attic is unfinished and/or not sufficiently insulated, consider completing both. Between this and sealing up your attic hatch, you can save as much as 30% on your heating costs – and enjoy a more comfortable home.

Haley Mechanical is committed to providing Michigan homeowners in the Dexter, Ypsilanti, Ann Arbor and surrounding areas with expert advice on heating and cooling your home. Call us today with any questions you may have about saving on energy costs this winter.

What Do All of These Energy Ratings Mean?

Utility Meters

Sorting Out All of Those Numbers

Anyone, whether a home or business owner, has likely seen data related to energy rating listed on a product when shopping for a new cooling/heating system, or even a window unit. What do those numbers mean, and how do you compare one product to another? Understanding these numbers can save you a bundle on energy costs. We’ve provided some information below to help you make a smart, energy-wise choice.

Energy ratings

Energy ratings help you compare cooling and heating equipment to determine how much energy is necessary to keep you comfortable. Essentially, it is comparable to the miles-per-gallon you get in a car. Vehicles that use more gas require more money to get from one place to another. Efficiency numbers make it possible for you to know how much energy is consumed to enjoy the same performance you would get with similar products. When it comes to electric heat pumps or gas furnaces, you cannot compare ratings because these systems rely on different types of fuel. Whether your air conditioning and the heating system relies on electricity, gas, or both, understanding the numbers behind the ratings will give you a good idea of how much it will cost to run your system and enjoy a comfortable home or business.

Electric cooling and SEER (Seasonal Energy Efficient Ratio)

A SEER rating gives you a good idea of what you can expect to spend on energy costs, as this rating system measures the performance of the equipment over an entire season, such as summer months when most people need cooling.

How do you calculate SEER? It’s easy. Take the total cooling output the equipment will generate over the summer (BTUs, the measurement standard also known as British Thermal Units) and divide this number by your total energy expenditure (dollars spent) during this same period. You measure the cost to enjoy a cool home in comparison to the level of cooling power the system provides. Currently, the Lennox R XC25 is the most efficient cooling system available, providing a SEER rating of as much as 26. A minimum SEER of between 13 and 14 is mandated under federal law depending on the country where you reside. Air conditioners with a SEER of more than 14.5 may qualify for ENERGY STAR; when you see this qualification, you know it is a smart investment regarding energy-efficient cooling.

AFUE, or Annual Fuel Utilization Efficiency

AFUE numbers deal with systems that use fuels such as oil or natural gas to generate heat during colder months. This is a different method used to measure efficiency and is a comparison of the heat generated over the course of winter months with the amount of fuel burned.

Annual Fuel Utilization Efficiency numbers are fairly easy to understand. The higher the number, the more heat you will feel for a specific amount of oil or natural gas burned to produce that heat. Furnaces labeled 90% or higher for AFUE are highly efficient, as this means that 90% of the fuel is transformed into useable heat, and only 10% wasted. To go a step further in helping you understand AFUE rating, a furnace rated 80 will use 80% of the oil or natural gas to heat your home/business, wasting 20% of the fuel. The waste is typically caused due to inefficient burners, air leaks, or designs that are not as advanced as others. The Lennox SLP98V furnace currently has an AFUE of 98.7, which means less than 2% of the fuel is wasted – super efficient for winter months!

According to a January 2013 publication by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) the XC25 air conditioner and XP25 heat pump are the most precise and efficient models available today, based on the SEER of similar heating and cooling products. For exact system efficiencies, you can consult with AHRI or a Lennox dealer such as Haley Mechanical.

HSPF, or Heating Season Performance Factor

Heat pumps don’t use fossil fuel and work as an air conditioner that’s capable of running in reverse to heat your home or business in winter months. Therefore, they have their comparative efficiency rating as AFUE does not apply in this case. How efficiently a heat pump warms your indoor air over the course of the entire winter is measured by HSPF. A heat pump with an HSPF of more than eight is considered high-efficiency; also, you may qualify for tax credits or utility rebates. How do you calculate HSPF? Divide the system’s heat output over the course of the season by the amount of electricity necessary to produce the heat.

Keep in mind that a heat pump will have an HSPF and SEER rating when shopping for this type of system because it relies on electricity to both cool and heat your premises. The Lennox XP25 heat pump mentioned earlier in this article currently offers an HSPF of as high as 10.20, and a SEER of up to 23.5.

Is Your Air Conditioner Prepared for Spring?

Spring Tree Blossoms

Nothing brings about a good mood quite like spring! Following a long, cold winter, those first few days are invigorating, bringing about desire and readiness to start fresh – doing a little spring cleaning, making repairs, just getting ready for the warmer spring and summer months. As trusted Ann Arbor air conditioning professionals, we have one question: Have you had your air conditioner cleaned and inspected in preparation for spring?

An air conditioner properly maintained and cleaned means:

Improved indoor air quality. Until your air conditioner breaks down, you probably don’t give it much thought. Before we get into the summer season in which your system will likely be used heavily, it is important to schedule an annual checkup. The air that’s distributed through your home goes through a filter, which directly impacts the air your family breathes. A clogged or dirty air filter not only means dusty, dirty air but potentially mildew or mold that has accumulated on the filter. This can result in serious health issues!

Enhanced efficiency. The filter not only affects how clean the air is inside your southeast Michigan home but your air conditioner’s efficiency. When the filter is dirty, your system has to work harder to pump air into your home. This means more wear and tear on your system and a higher energy bill. Of course, the filter is not the only component that may affect efficiency. If your system is older or has been neglected over the years, it may be time to have a new, more energy efficient model installed. Our HVAC contractors can inspect your system, make any necessary repairs, or help you determine whether you would save substantially by having a new system installed.

Cool comfort all spring and summer long. The biggest advantage of having your air conditioning system cleaned and maintained is that you will stay cool all season, and keep cooling costs down. If you wait until the end of spring or until your A/C breaks down, it is likely you’ll have quite a wait for a technician to make repairs as this is the busiest season for air conditioning contractors. By having your system checked and tuned up now, any minor problems or issues can be diagnosed before they become a huge – and costly – headache.

At Haley Mechanical, we cannot stress enough the importance of getting your air conditioner prepared for the spring and summer seasons. It is time for a little spring cleaning, and this includes your cooling system! Call us today and enjoy peace of mind knowing your air conditioner will provide clean, comfortable air all summer long.

Spring, the Ideal Season to Replace Your Cooling & Heating System

Spring, the Ideal Season to Replace Your Cooling & Heating System

With just a few weeks left during the spring season, if you are considering replacement of the heating and cooling system in your southeast Michigan home, now’s the time to do it!  Why is spring the ideal time for a replacement?

Specials and savings.  Many manufacturers offer special deals and savings during the spring season.  To learn if there are special incentives available or how you can save money by purchasing a system now rather than waiting, be sure to check out the Lennox Promotions Page.

Weather.  Consider how hot it may during summer months, and think about the frigid temperatures in winter months in Michigan.  Doesn’t it make sense to have your air conditioning system replaced during spring when temperatures are mild and comfortable?  If it takes a few hours or even a day to install your new system, you will not be suffering extreme heat or cold!

Is replacement the best option for you?

SE Michigan homeowners often debate whether to repair or replace, especially when it seems that repairs are becoming necessary more and more often.  Can you repair it one more time and hope it lasts through the season or is it time to replace?  Consider these factors:

  • Repair costs
  • Efficiency
  • Your equipment

When repair costs are adding up, it may be more cost-effective over the long term to simply replace your heating and cooling system.  If you are experiencing constant repair bills and wonder when the next break down is coming, it is probably time to replace.  The cost will not seem so hard to bear when you consider the utility rebates and tax incentives a new, high-efficiency system often qualifies for.

Modern, high-efficiency systems provide the ultimate in comfort while using substantially less energy.  HVAC systems increase in efficiency every year; when you have a modern system installed, you will enjoy lower energy costs each month.

How old is your air conditioner, heat pump, or furnace?  No equipment lasts forever, no matter how well maintained.  Furnaces usually last about 15 to 20 years, while air conditioners and heat pumps usually have a life span of about 10 to 12 years.  If your system has gone beyond its life span, you may be counting down the days (or even minutes) before it finally breaks down for good.  Not only that, there are so many features today that enhance convenience and comfort, such as air quality monitoring, remote operation via your smartphone, and proactive energy savings, another feature that works using GPS on a smartphone.

Dealer-offered financing helps you afford more system

Dealer-offered financing makes it possible for homeowners to enjoy even greater comfort and efficiency, as the ability to finance your new home comfort system rather than spending a significant amount of money all in one fell swoop means you can get more system!  The advantages of spending more on a high-quality, high-efficiency system include:

Additional features.  Wouldn’t it be great if you could communicate with your system?  You can have maximum control over humidity and temperature and enjoy energy savings via a thermostat that adapts system use to your schedule in real time by upgrading to a system you can communicate with.

Savings over the long haul.  While initial costs may be more, financing helps you spread the expense over time so that you can easily manage your finances while enjoying the highest efficiency air handlers, furnaces, air conditioners, or heat pumps.  Ultimately, the more you spend on high-efficiency equipment, the more you can save each month on utility costs.  In fact, in some cases, you can save up to 50% when compared to less efficient, standard equipment!

Better system performance.  Financing makes it possible for you to purchase the entire heating & cooling system, so you are not forced to replace components piece by piece as they fail. This means you are getting the most modern, efficient system with components designed to work together for the ultimate in functioning and efficiency.  Superior performance, more control, and savings on monthly energy costs.  What could be better?

As a Lennox dealer, Haley Mechanical can help you choose the system that’s ideal for your home and comfort needs.  Give us a call today, and enjoy the benefits of financing and having your system installed during the spring season!

Air Conditioning Facts That May Surprise You

Audience in air conditioned auditorium

As a SE Michigan homeowner, you probably wouldn’t want to face some of the super-hot days we’ve seen this summer without air conditioning! While there’s nothing better than a nice day in the sunshine, it’s a relief to know you can retreat to the cool indoors when you’ve had enough. If your A/C isn’t functioning as efficiently as it used to or you’re having problems, it may be time to call in our skilled air conditioning technicians. While you consider making the call, you may enjoy some of these surprising A/C facts.

  • We’ve lost our tolerance to heat thanks to the invention of air conditioning! According to research, the cooler the indoor temperature is inside your home, the less tolerant you are of the heat.
  • The U.S. has experienced 60% of its economic growth in the southern states, largely due to the fact that people flocked to states like Arizona, Florida, and Texas after air conditioning made tolerating the heat in these regions possible.
  • Willis Carrier designed the first air conditioner in 1902, but it wasn’t for the purpose of cooling. Carrier had a publishing house, and the humidity would cause ink to smudge and papers to expand and contract. The purpose of the design was to eliminate humidity!
  • How much energy is consumed in the U.S. to power air conditioners every year? As much as the entire continent of Africa uses in a year’s time to power everything. That’s a whole lot of energy!
  • Who can teachers and school children thank for summer vacation? Air conditioning! Summer breaks were the norm for schools prior to the invention of air conditioning so that students and faculty didn’t have to suffer the heat. The tradition continues today.
  • The creating and testing of vital medications is possible because of air conditioning – but why? An environment in which the temperature can be controlled and kept cool is essential for pharmaceutical companies, hospitals, doctors, and others in the medical field for creating and testing.
  • People flocked to movie theaters during the summer months during the Great Depression, because they were some of the few businesses who had air conditioners. If you’re familiar with the term “summer blockbuster,” now you know where it came from! Large Hollywood crowds were the first to see big film releases.

For all your air conditioning needs, call Haley Mechanical today. Our NATE Certified technicians are the experts when it comes to troubleshooting, repair, or replacement.
