Do’s and Don’ts: Making Your HVAC System Energy Efficient

When it comes to saving on energy costs, some tips can save you hundreds, while others can be downright counterproductive. To help you sort through the abundance of HVAC advice, here’s a list of some things you should do to save energy, and others you should always avoid:

Do Use a Programmable Thermostat
You’re not inside your home for most of the day, so why are you paying to heat or cool it as if you were? By using a programmable thermostat, you can get around paying for HVAC costs in your Manassas home when you’re not at home, and still stay warm (or cool) when you are. Turning your thermostat up or down 10 degrees for just eight hours per day can save you up to 15 percent on your annual heating and cooling costs.

Do Hire a Professional to Seal Leaks
Investing in the most efficient HVAC unit available won’t make a difference if your home and air ducts aren’t sealed against leaks. According to the U.S. Department of Energy, you can save up to 20 percent on your heating and cooling costs by patching up leaking air ducts alone. Call a Manassas HVAC repair company and schedule a professional duct sealing service.

Do Replace Your HVAC Unit (If It’s Worth It)
A new furnace or new air conditioner could substantially reduce your heating costs, but the investment isn’t always worth it. If your HVAC unit is just a few years old and in good repair, you may find better results in ducts sealing and other efficiency improvement. For units over a decade old, the much higher efficiency ratings of new HVAC systems can make a replacement a worthwhile investment.

Don’t Use a Fireplace to Supply Heat
Sure, fireplaces are picturesque, but they are one of the most inefficient ways to heat your home. Fireplaces draw more heat out of your home than they create, with heated air leaking through dampers and out through your chimney. During the winters months, find other ways to make your home cozier.

Don’t Close Vents to Save Energy
Homeowners in the poorly insulated homes of yesteryear would often close vents in unused rooms to concentrate heat into living areas. With today’s forced air systems and well-insulated homes, this is no longer a good way to save energy. In fact, you can end up using more energy than you save by closing vents in unused rooms. A 2003 study by the Lawrence Berkeley National Laboratory found that leakage through air ducts increased in homes with closed vents.
