Duct Sealing Service in Southern Maryland

Duct Sealing Service in Southern Maryland

If your home or business triggers high utility bills or features an HVAC system that runs constantly, it's time to take some cost-saving steps. Upgrading the seals of your ductwork, a routine maintenance step, could provide a giant leap in that direction. Leitch Heating & Air Conditioning will provide Aeroseal services to your home or business in Southern Maryland that seal existing ducts and make your system air-tight once again.   

Studies show more than 90% of existing buildings in North America have air duct systems that contain small holes and cracks that reduce the level of comfort and increase heating and cooling costs. Leaks are caused by several factors, including the age of the building, type of construction, type of ductwork and local building codes.

Leakage duct Leakage duct

Repairing and patching leaks in HVAC duct systems saves energy and cuts expenses. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leak means extra air must be supplied to adequately heat or cool the conditioned space.

This not only increases heating and cooling loads, it also increases fan energy, system run time and energy costs. Sealing duct leaks reduces the amount of heated or cooled air needed for the conditioned space, saving you money.

Duct Sealing Services Save More than Money

When it comes to indoor air quality, sealing duct leaks can save more than money. If your home or business battles unpleasant odors or excessive dust, leaky ductwork could be the culprit. Sealing those leaks can stop the musty smells and impure air that threatens the health of family members or the continued loyalty of business clients.

20 to 40% leakage in duct systems at 75 % of the homes

Like a good transmission sends power to all four wheels of a car, a good ductwork system pumps pure air to all rooms in your home or building. In residential buildings, leaky ductwork not only allows air to escape from your HVAC system, it permits contaminants from untreated air in your crawl spaces and attic to be pulled in to the air your family breathes.

During our service calls, we find 20 to 40% leakage in duct systems at 75 % of the homes we visit. Many of those systems pull in bad air, harming the air quality of those homes. In commercial buildings, leaks in return ducts and ventilation shafts can create air contamination that causes odors and an unhealthy indoor environment.
