Energy & Money Saving Tips


The typical duct system leaks approximately one-third of the air passing through it. This air loss can cost hundreds of dollars a year in energy expenses. This is air you are paying to heat/cool in order to maintain a comfortable home, but instead is leaking into attics, walls, crawl spaces, etc. To compensate, your system has to work overtime to try to keep up resulting in excessive energy expenses, poor comfort and undue stress on your comfort system.

We’ve discussed the Whole House Approach to Comfort in the past and touched on the impact of your duct system. The location of your supply/return registers, the resistance and airflow capacity resulting from the design of your duct system will help or hinder system performance and your comfort. Another major factor is duct leakage. It’s a known fact that all duct systems leak air, the question is to what degree or more importantly, to what result.

If you’ve noticed vents that produce very little airflow in certain rooms, significant temperature differences room to room, the area around your indoor unit is always hot/cold depending on the season, high humidity in the summer, high energy usage or your system seems to run all the time; these are all symptoms of typical duct leakage.

The majority of your duct system is hidden away between floors, walls, attics and crawl spaces. Each and every connection, seam and transition has leakage. The bottom line is conditioned air is leaking into areas outside your living space instead of being delivered to where you need it. In addition, leakage in return duct draws air in from all these unwanted areas. Not only is this affecting your air quality, but air from an attic/crawlspace brings with it extreme temperatures and humidity which creates additional challenges for your system to overcome.

Because most of the duct is inaccessible, it’s been something that we just had to live with. However, we’ve uncovered a technology that allows you to seal the duct system from the inside with virtually no interruption to the living space of the home. Aeroseal is a product that allows you to quantify the actual leakage, seal the holes and measure the improvement in real-time during the process. The end result: improved comfort, reduced energy usage and better air quality.

If your like most of us, we are always looking to save money on energy cost. Below is a quick list of twelve ways to reduce your air conditioning cost this summer.

  1. Stay cool, but not too cool! – The first place to reduce your air conditioning cost is with setting the thermostat to a cool, but not too cool setting. Our customers find they can easily stay pretty cool at 75°F to 78°F. In many cases you can save upwards of 5% in cooling cost for every degree you raise your thermostat.
  2. Don’t trick your thermostat – A thermostats job is to sense heat and adjust to keep you cool. Things like televisions, lamps, PC”s and direct sun light all impact the heat in your home. By turning off these items or pulling down shades will keep your home cooler and reduce your air conditioning cost this summer.
  3. Slow and easy wins the race – When that first hot day comes and you’re ready to turn on your air conditioner, take it easy and set the thermostat to the desired temperature.  Many people will crank the temperature way down to try and boost the cold air. This does not work and will only increase your air conditioning cost. Remember our goal is to reduce your air conditioning cost.
  4. Keep the air flowing – Air flow is very important to keeping a consistent temperature in your home. Make sure that nothing is blocking your vents. When the cool air can circulate with ease, it reduces the need for more cooling, thus reducing your air conditioning cost.
  5. Keep it clean – An easy way to reduce your air conditioning cost is to clean and/or replace your filters monthly. Dirty air filters restrict the air flow and reduce efficiencies.  To make this task even easier we have a Filter Program which delivers filter right to your home! Heck, we will even send you a reminder email monthly so you do not forget.
  6. Get a little help from your friends – Many newer systems do a really good job at removing the hot air from your home, but homes with older systems might struggle to keep up.  In these homes you want to install a whole home ventilating fan in the attic.  Removing extra warm air from your home will create less stress on your system and reduce your air conditioning cost.  A low cost solution would also be to install a window or two.
  7. It’s always cooler in the shade – Just like sitting under a big oak tree on a hot day, it’s always cooler in the shade. Your home is no different, the more you keep the sunlight out the cooler it will be. Make sure to close the blinds that take direct sunlight.  It’s amazing how a little shade can help to reduce your air conditioning cost.
  8. Get sun glasses for your windows – Just like sun glasses protect your eyes from sunlight, window tinting and reflective window film will protect your home from sunlight and unwanted heat. The less heat in your home, the less your air conditioner will run, thus helping to reduce your air conditioning cost. Window film has an added benefit, whereas it also protects your furniture, carpet, and hardwood from fading over time.
  9. Share the cool air – If you have room fans or ceiling fans, turn them on! Moving the cool air around your home will help to even the temperature and reduce the demand, and this will help reduce your air conditioning cost.
  10. Hose it down – Once a year you should spray down (with low pressure water) your outside unit (the condenser). Make sure to turn off the unit at the thermostat before doing this. A clean outside unit will help to make your system more efficient and reduce your air conditioning cost.
  11. Seal it up tight – Often times you will have air leaks in the exposed duct work on or around your main heating and air conditioning unit in your basement. Use metal tape (found at your local big orange box) to seal up those leaks. Sealing these leaks will get more air upstairs to the rest of the house where it belongs. This will reduce demand for cool air and reduce your air conditioning cost.
  12. Going green helps – Like we said it about shade, so why not give back to the planet while reducing your air conditioning cost by planting some trees. This not only helps the environment, but it also will reduce your air conditioning cost by providing shade on those sunny sides of your home.

The answer could be both. Many homes experience excessive dust that can cause pollutants which can increase allergy reactions and decrease air quality. Homeowners try to stay on top of the this by replacing air filters frequently, scheduling regular maintenance, and even purchase expensive air filters just to hold back the dust. But it just keeps coming back.

The logical next step is duct cleaning right? Well maybe. Duct cleaning is a popular way to address dusty homes and in fact I read recently that 13% of Angies List members have regular duct cleaning. The keyword here is “regularly”. That’s right the dust in your duct work comes back after duct cleaning. This routine duct cleaning is not solving your problem.

What if you could not only solve your dust problem without duct cleaning, but you could reduce your annual energy cost by as much as $700.00!

duct sealing

The measured result above are from a typical Aeroseal air duct sealing process:

Have you ever asked yourself where the dust is coming from?

According to the Environmental Protection Agency (EPA) the average home accumulates about 40lbs of dust per year. Where is this coming from, you clean the house weekly, your have good screens on your windows, you have your HVAC serviced and air filters regularly replaced, but you still see the build up on your intake vents, tables, etc.

Let me ask you, have you cleaned behind your walls lately? Of course not, right. But what if I told you that is where the dust could be coming from. Did you know 90% of existing buildings in North America experience small holes on the duct work. These holes continually pump dust and other pollutants into your HVAC system and then out to your home.

The solution is duct sealing.

This process is simple, easy and can reduce your energy cost by as much as $700.00 per year. Duct sealing seals your ducts from the inside and is guaranteed for 10 years , no more annual duct cleaning. GAC is partnered with Aeroseal the nations oldest and best duct sealing manufacturing. One visit from our technicians and we can reduce the duct leakage by 90%.

Most people don’t spend a lot of time thinking about their air ducts. But did you know that sealed and insulated ducts can make your home more comfortable and energy efficient? Did you also know that energy efficient is basically code for saving money on your monthly utility bills?

There are several signs that your home could benefit from duct sealing:

  • High utility bills
  • Rooms that are too hot in the winter/too cold in the summer
  • Excessive dust in your home

When you have leaky air ducts, it reduces the efficiency of your home’s HVAC systems. Duct sealing can therefore help save you money by increasing the efficiency of your system’s performance and therefore lowering your energy bills.

Of course there are other benefits to duct sealing:

  • Duct sealing can help improve your home’s indoor air quality.
  • It also reduces the risk of backdrafting, if you have a gas furnace or water heater.
  • Since duct sealing helps conserve energy, it’s also a great way to minimize your home’s environmental impact.

Heating and cooling your home account for more than half of your home’s energy use and consequently, utility costs. We’re not making this up—take a look at how the Department of Energy breaks it down:

  • At 45 percent, heating accounts for the biggest portion of your home’s energy bills
  • Next up is water heating, at 18 percent
  • Following that is cooling at 9 percent
  • The rest breaks down into electronics, lighting, cooking, refrigeration, etc.

As you can see, one of the biggest opportunities for cutting down on your home’s energy use lies in your heating and cooling equipment.

So how can you make your home’s heating and cool more energy efficient? There are actually a number of ways to go about doing this, but today we’re going to discuss green HVAC equipment.

If it’s about time for you to think about your replacing your unit, chances are you might have interest in a green HVAC system—both from an environmental standpoint and a lower energy bills standpoint. (It’s still noble; we promise.)

What to Look for in a Green HVAC System

The easiest way to make sure you’re installing a green HVAC system is find one that meet the specifications of the ENERGY STAR program. And according to the Department of Energy, replacing your old HVAC system with ENERGY STAR qualified equipment can cut your annual energy bill by nearly $200.

Here are the specs:

Green Furnaces

Here in Montgomery County, we’re several months into winter. Are you already getting tired of seeing

those sky-high heating bills? Even if you turn your thermostat down, you might still find yourself

shivering and paying way too much. But there are a few surprisingly easy steps you can take to reduce

those bills and increase your comfort. Talk about a win-win.

1. Have your furnace checked by a professional. It’s not too late for a furnace tune-up. During our

inspection, we’re not just making sure your furnace doesn’t break down (though of course we

do try to reduce that risk), we’re also making sure it’s running as efficiently as possible. A few

tweaks to your settings or a basic cleaning of parts can result in big savings, so if you haven’t had

a check yet, schedule it today.

2. Cover your windows. No matter how much you caulk those drafts, cold air is still going to sneak

in through the windows. Your best bet is to keep them covered. Consider putting up thermal

curtains. These thick, insulated panels lock your warm air in and the cold air out. They also come

in a variety of designer colors and designs, so you won’t have to sacrifice fashion for comfort.

You might even consider keeping the curtains up into the summer months; they’ll reduce your

cooling costs and many are even light-proof, helping the kids sleep while the sun’s still up.

3. Insulate the unlikely places. You’ve probably wrapped some padding around your pipes to keep

them from freezing; maybe you even added a new layer of insulation in your attic. But did you

insulate your water heater? Many new water heaters are already insulated, but some aren’t. If

it’s in a cooler area, like a basement or garage, it will have to work harder to keep your water

hot. Look for water heater insulation kits, and you could see a water heating savings of 4-9%.

Also don’t forget about your electric sockets; these little outlets can let a shocking amount of

cold air into your home. You can find insulating covers for pennies at your hardware store.

4. Winter proof your fireplace. How often do you really light a fire? It always sounds like a good

idea, but then you have to haul wood and get kindling and somehow, all those roaring fires just

never happen. If your fireplace isn’t in use, make sure your damper is closed. If possible, also use

a fireplace screen just to keep those last drafts out.

You’ll be amazed at how much you can save—and how much better your home will feel—just by taking

these small steps. And if you’re still not comfortable in your home, it’s time to call in a professional.

If you have problems with your furnace or still need that heating check, call GAC. We serve Maryland

homeowners to keep them comfortable all year ‘round. We’d love to help you, too.

Have you ever gone to the doctor and felt there was something not quite right about their recommendation? In that case, you go get a second opinion. Sometimes they confirm that the first doctor was right, but sometimes they find another explanation or a simpler solution to your problem. We see the same thing in HVAC all the time.

For instance, recently a Frederick County homeowner came to us for a second opinion. The first HVAC company they called said they would need to replace the heat exchange on their furnace. This is a costly repair that can cost several thousand dollars. Understandably, they wanted to make sure that was the issue, so they called us.

Our technician came and took a look at the furnace, but wasn’t convinced the heat exchange was to blame for their problems. He decided to take a look at their outside vent, just to make sure nothing was blocking it and keeping it from working. Sure enough, the vent was almost entirely blocked by mud dauber wasp nests. We were able to clear that out and resolve their problem for just over $100 rather than thousands. Not to mention replacing the heat exchange wouldn’t have made any difference if the vent was still blocked.

If you ever feel that you’d like a second opinion on your HVAC system, you should never hesitate to ask. In this case, the client asked a different company for a fresh set of eyes, but we even offer second opinions on our technicians. If you ever feel that there’s something more going on or our technician might have missed something, we’ll send another technician to your house at no charge to make sure everything’s in order. In the end, we’re interested in building a long-term relationship with you, and we want to make sure we’ve really solved your problem. Sometimes a second look is all you need.

Whether this is your first opinion or your second, we’d love to talk to you about your HVAC system. Contact GAC today and we’ll help you diagnose your problems, replace your system or get you on a maintenance plan that keeps your system humming all year round. Click here to schedule your appointment today.

Did your mom or dad ever scold you to shut the door because “we’re not paying to heat the outdoors”? Even if you’ve got all your doors and windows shut and locked, chances are you still are paying to heat the outdoors. About 1/3 of all the air you pay to heat or cool will wind up escaping through your duct system into your walls, your attic, your basement, your crawlspace and other uninhabited areas. In return, your HVAC system is also drawing fresh air in through those same gaps and chinks in your ducts. Think about it: do you want to be breathing air from your attic or crawlspace? It’s dirty, which is unpleasant for you and makes your HVAC system work harder. Bottom line: leaky ducts mean more expensive heating and cooling bills and less comfort overall.

The solution, in most cases, is surprisingly simple. You don’t need to replace your ducts or go to any drastic extremes. We work with Montgomery County homeowners to protect their ducts using a product called Aeroseal. This duct sealer is an aerosol spray which is injected into your ducts. As tiny holes in your duct draw air toward it, the Aeroseal particles smack right into them, sealing them up tight. Now, air moves through your ducts the way it’s supposed to, and into the areas of your home where you most need comfort. The whole process takes just a few hours and can reduce leaks by up to 98%.

Sometimes, we find that people are skeptical about how much air is really escaping through their ducts. But once they’ve had Aeroseal, they’re believers. It’s not unusual to hear that after an Aeroseal treatment, homeowners are surprised to find the toilet paper fluttering in their bathroom. For the first time, their HVAC system is working to its full capacity to keep them comfortable, rather than to heat the uninhabited nooks and crannies of their home.

The duct sealing treatment comes with a 10 year warranty, and often customers see energy savings within 2-3 years that totally pay for the cost of the sealing. All in all, it’s a great solution for your wallet and for your overall comfort.

Interested in trying Aeroseal in your home? Contact GAC Cooling & Heating (Gaithersburg Air Conditioning and Heating) today. We’ll inspect your ductwork, determine if you’re a good candidate and help you understand what kinds of results you might see. Schedule your appointment now.

When you’re a homeowner in Maryland, you strive each day to make sure it is safe, clean, and comfortable. With winter just around the river bend corner, your heating system is probably one of your top priorities. You might be wondering if you should get it serviced before the cold really hits, whether it will last another year, or if you should bite the bullet and replace it, what you should replace it with, and more.
Obviously, a heating system is not a small investment. That’s why we’ve put together the ultimate Maryland home heating guide so you can make the most informed decision as possible when it comes to heating your home.

Choosing a Heating System

Most Maryland homeowners choose to heat their houses with a furnace or heat pump (click here if you’re confused on the difference between a heat pump and a furnace).

Types of Furnaces

There are several different types of furnaces you can choose from for your home. Which one you choose will usually depend on which type of fuel source is readily (and cheaply!) available in your area:

  • Natural gas furnaces – In most areas, it costs much less to heat your home with natural gas than with electric, oil, or propane. Natural gas furnaces produce less carbon dioxide, making natural gas furnace installation an environmentally-friendly option.
  • Propane furnaces – Propane furnaces offer fast heating at high temperatures and will heat your home even in the event of a power failure.
  • Oil furnaces – Depending on the cost of natural gas in your city, oil furnaces can be the least expensive way to heat your home in some areas.

Annual Fuel Utilization Efficiency

Of course there are other things to consider in addition to fuel source. If you’re interested in installing a fuel efficient furnace (which, I mean, why wouldn’t you be?), you’re going to want to look for one with a high Annual Fuel Utilization Efficiency (AFUE) rating. For example, Bryant gas furnaces operate between 80 percent and 97 percent AFUE.

Choosing the Right Size Furnace

Your furnace needs to be sized to accommodate your home’s unique heating needs. In order to do this, a professional needs to measure your home and calculate its heating and cooling load. This calculation is based on your home’s square footage, windows, walls, ceiling, floor plan, appliances, insulation, exterior, and more.). A professional will also consider your duct configuration, number of home occupants, and your lifestyle before recommending the ideal furnace size for your home.

Furnace FAQs

Is it okay to install a different brand of air conditioner and furnace?
Yes – most brands of HVAC equipment will work properly together provided the coils and blowers are the proper size. At worst, you’ll see a slight drop in efficiency or capacity.
How long will my furnace last?
With proper maintenance, you can expect your furnace to last 15-20 years.
When should I replace my furnace?
The following symptoms usually indicate that it’s time to replace your furnace:

  • Frequent pilot light outages
  • Delayed ignition
  • Yellow flame or wavering flame
  • Excessive soot or corrosion
  • Too much or too little heat
  • The smell of sulfur or burnt eggs

What do I need to do to maintain my furnace?
Your furnace will perform more efficiently and last longer if you keep it well maintained. This includes things like:

  • Inspecting filters once a month and changing them if they are dirty
  • Making sure the supply and return vents in your home are not obstructed by things like furniture, curtains, boxes, toys, etc.
  • Checking your chimney and venting systems once a year for secure fittings, leaks, corrosion, or damage
  • Keeping the area around your furnace clean and clutter free for at least three to four feet on all sides
  • Allowing adequate combustion air for your furnace, making sure it has enough space to breathe

Are there tax credits or rebates for a new furnace?
Furnaces with a 95 AFUE or higher can qualify for tax credits in 2013. Click here for more info.

Heat Pumps

We discuss the benefits of heat pump installation pretty regularly on our website, so we probably don’t need to go into too many details here. However, keep in mind when you’re choosing a new heating system that:

  • Heat pumps both heat and cool your home
  • Heat pumps are an energy efficient heating option
  • Heat pumps can help you lower your heating bills
  • Heat pumps allow you to use hybrid heating

Types of Heat Pumps

There are two main types of heat pumps you can install in your home:

  • Ground source heat pumps – Also known as geothermal heat pumps, these heat pumps are electrically powered and transfer ground source heat from the ground into your home during the winter (and operate in reverse during the summer).
  • Air source heat pumps – Rather than transferring heat from the ground, an air source heat pump transfers outdoor air heat indoors during the winter (and operates in reverse during the summer).

Heat Pump FAQs

Will a heat pump work well in cold climates?
Heat pump installation used to be mostly recommended to those that live in moderate climate areas—like Maryland. According to the U.S. Department of Energy, heat pumps do not generally perform well during extended periods of sub-freezing temperatures. But as heating technology improves, more and more manufacturers offer heat pumps that are suitable to those living in colder climates.
For colder climates, we recommend something along the lines of Bryant’s Extreme Heat Pump—which delivers twice the capacity in freezing temperatures.
Are there tax credits or rebates for a new heat pump?
Yep! The following heat pumps qualify for a $300 HVAC tax credits in 2013:

  • Split system electric heat pumps with 8.5 HSPF, 12.5 EER, and 15 SEER
  • Packaged electric heat pumps with 8.0 HSPF, 12.0 EER, and 14 SEER

Click here to learn which heat pumps qualify for Pepco rebates.
Is a heat pump better than an air conditioner?
Heat pumps both cool and heat your home—meaning there is no need to purchase, install, repair, and maintain two HVAC systems. In the summer, your heat pump transfers your indoor heat to the outdoors rather than converting energy into heat. Because they don’t convert energy into heat, a heat pump can save you money on your energy bills while still keeping your home comfortable. Additionally, heat pumps are more effective at dehumidifying than air conditioners.

Heating Accessories

Now that you’ve (hopefully) decided what type of heating system you want for your home, you can start to think about what other types of heating accessories you need to compliment your system and further increase its efficiency. Bonus points? You’ll also be increasing your home comfort.

Programmable Thermostats

While you don’t necessarily NEED a programmable thermostat, they do make it a lot easier to save energy and stay more comfortable. You can program the thermostat so that it raises and lowers the temperature automatically to meet your needs, i.e. lowering it when no one is home and raising it when everyone gets home. Programmable thermostats are particularly effective when your household is on a regular schedule and the program operates continuously.


You love that your heating system keeps you warm, but you probably don’t love that it dries out your air. If you have a heat pump, you likely won’t experience dry air and will therefore not need to worry about a humidifier.

For furnaces, however, a whole house humidifier can be a great investment to improve your home comfort and also save you money. A home with higher humidity will feel warmer, allowing you to be more comfortable at lower temperatures.

Zoning System

A zoning system consists of control, automatic motorized dampers and temperature sensors working in conjunction with your heating system. The dampers are placed inside the supply ducts to control the airflow to specific areas of your home. The temperature sensors are located in the separate zones of your home. It’s similar to having a separate thermostat in each area communicating with your heating system—allowing each zone to be heated independently.

High Efficiency Air Filters

High efficiency air filters remove even the smallest pollutants from the air in your home—making them ideal for your heating system if anyone in your family suffers from respiratory problems or allergies. A highly efficient filter will also extend equipment life and reduce fuel consumption by 10-15 percent. Remember, it is vital that you clean or replace your air filter regularly.

Taking Care of Your Heating System

To extend the life of your furnace or heat pump, we recommend the following:

Choosing a Heating Contractor

Now that you’ve decided which system you want and any accessories you might need, we decided we’d help you with a final crucial step: choosing an HVAC contractor in Maryland to install your new heating system.

Until you find an HVAC company you are comfortable with and that you trust, we recommend getting at least three estimates from three different companies.

The company you choose is the most important decision you’ll make regarding your new heating system. Proper installation, the expertise of the consultants, reliability and convenience of their support, and your comfort level should be the major factors behind your final decision.

Of course, if you’re ready to choose GAC as your HVAC contractor in Maryland, we certainly won’t be upset!
