What is AFUE?

AFUE stands for Annual Fuel Utilization Efficiency and is a rating used to describe the efficiency of your heating system. The higher the AFUE, the more efficient the system.

Is it ok to install a different brand of air conditioner and furnace?

Yes – most brands of HVAC equipment will work properly together provided the coils and blowers are the proper size. At worst, you’ll see a slight drop in efficiency or capacity.

How do I choose the right size furnace?

Your furnace needs to be sized to accommodate your home’s unique heating needs. In order to do this, a professional needs to measure your home and calculate its heating and cooling load. This calculation is based on your home’s square footage, windows, walls, ceiling, floor plan, appliances, insulation, exterior, and more.). A professional will also consider your duct configuration, number of home occupants, and your lifestyle before recommending the ideal furnace size for your home.
