When it comes to selecting the right furnace for your home, there’s no shortage of options to choose from. For heating and air conditioning in Lawrenceville, GA, you have to consider the size of your home, your existing ductwork, and energy efficiency.

The Size of Your Home

Whether your shopping for a new air conditioning unit or a new furnace, you have to take the size of your home into consideration. Furnaces are measured using BTUs or British Thermal Units. To determine how many BTUs you need for your home, you need to know the square footage of your home. Multiply the square footage of your home by 20 to get the minimum number of BTU needed for your new unit. A unit that’s too small won’t be able to keep up with your heating demands while a unit that’s too big will cycle on and off constantly causing needless wear and tear on your unit.

Aging Ductwork

Before you replace your old unit, ask your HVAC experts to inspect your ductwork to make sure it’s in working order. Holes and tears in your ductwork will exhaust warm air into your attic, costing you hundreds in wasted heating costs. Clogs caused by excess dust building inside your ducts force your unit to work harder to pull air through the system. A duct cleaning will remove excess buildup inside your system and improve the total air quality inside your home.

Energy Efficiency

It’s also important to select a unit that’s energy efficient. The Department of Energy’s Energy Star Program sets the standards for all newer HVAC units and furnaces. Chances are you’ve seen their familiar blue star logo on products like toasters, hair dryers, dishwashers, and other major appliances as well. In the United States, furnaces must meet the Annual Fuel Utilization Efficiency (AFUE) rating of at least 80% to be considered energy efficient.
