Maryland Furnace Installation Experts

A furnace is one of the most reliable heating systems available on the market. If you’re looking to replace your old, aging furnace, then look no further! GAC Services installs some of the most advanced products on the market, designed for maximum comfort levels and energy efficiency.

The average expected lifespan of a furnace can range anywhere from 10 – 15 years old, and as your furnace ages it becomes less energy efficient. A great solution to an old, aging furnace is to upgrade to a new, more energy efficient model. At GAC Services we have experience installing gas furnaces, propane furnaces, and variable speed furnaces (for maximum efficiency).

Heat Pump Installation

GAC is determined to provide our customers with the most cutting edge, energy efficient heating systems on the market. Heat pumps function as air conditioners during the summer and heating systems during the winter. They increase energy efficiency while eliminating the need for a furnace and air conditioning unit.

Hybrid Heating System Installation

In Maryland, you never know what kind of weather the winter months will bring. In order to maximize your heating system’s efficiency, consider installing a hybrid heating system. Designed to maximize fuel saving, a hybrid heating system—also called a dual fuel heat pump—combines the energy efficiency of a heat pump and the reliability of a furnace to increase savings.

When outdoor temperatures dip below freezing, your hybrid heating system will rely on a backup furnace to heat your home. When temperatures warm up above 32 degrees Fahrenheit, the hybrid heating system uses a heat pump to transfer heat between indoors and outdoors, instead of using fuel to convert energy into heat.

Contact GAC Services today to install a hybrid heating system in your Maryland home!
