If the energy bills for your Charleston, South Carolina, home are too high, it may be because your HVAC system has been working extra hard to compensate for air leaks. According to the Department of Energy, eliminating air leaks in your home can reduce your energy costs by 5 to 30 percent a year. In addition, it can also make your home more comfortable and extend the longevity of your HVAC system. Find out where air leaks commonly occur in your home.

Air Ducts

If you’re using a ducted HVAC system, you should have the ducts in your walls and ceilings checked for cracks and holes. These ducts serve the purpose of channeling conditioned air from your HVAC unit to different parts of your home. If they’re leaky, your equipment will have to put in more effort to keep your home cool or warm. This will result in energy waste, higher utility bills, and increased strain and damage to your system, which can significantly reduce its lifespan.

While you can inspect certain parts of the ductwork yourself, you may need professional assistance to access the concealed sections. Your air ducts should be sealed using mastic sealant or an HVAC aluminum foil tape.

Windows

Cool or warm air can escape from your home through the gaps around your windows, making your indoor space less comfortable and causing your HVAC system to work harder to maintain an ideal temperature. You can prevent energy waste by sealing your windows with caulk and weather-stripping materials. If you have single-pane windows, consider covering them with storm windows or replacing them with energy-efficient options.

Electrical Outlets

Leaky electrical outlets and switch plates are other culprits of energy waste, allowing outdoor air to enter your home and precious conditioned air to leak out. Installing foam gaskets behind the holes around the outlets can help you lower your energy costs.

Depending on their locations, air leaks can be easy or difficult to eliminate. If you need help with air conditioning repair, don’t hesitate to call AC Heating and Air Conditioning Services at 843-277-9928.
