What We Need From You
The questions to answer are the same standard questions you may be asked by a contractor. Please note that not every combination may be available. All systems utilize R454B refrigerant. The included condenser will be the lowest SEER2-rated model that complies with state regulations. If there are any issues with the selections you have provided, we will reach out to you to ensure that the system you receive is suitable for your home. For more information on each question, please see below:
Furnace AFUE/Efficiency
AFUE stands for "Annual Fuel Utilization Efficiency", which basically means that its a measure of how well your furnace will produce heat. If a furnace is rated for 40,000 BTUs and has an efficiency of 80%, then that means 80% of the fuel used produces 32,000 BTUs of heat (40,000 X 80% AFUE) per hour and the remaining 20% is lost through your venting as combustion byproducts.
Make sure you know what type of furnace your house is equipped for. An 80% Furnace will use a metal flue for venting gases out of your house, while a 90% or Higher Furnace will use plastic or PVC vents instead.
Furnace BTUs
BTUs (British Thermal Units) measure how much heat a furnace can produce. It is important that you choose the correct furnace size so your whole house can be efficiently and comfortably warmed. BTUs scale upward with house size, but please note that other factors may affect what size furnace you need.
- 40,000 BTUs - Ideal for small houses
- 60,000 BTUs - Ideal for small to medium size houses
- 80,000 BTUs - Ideal for medium houses
- 100,000 BTUs - Ideal for medium to large size houses
- 120,000 BTUs - Ideal for large houses
Furnace Cabinet Width
Modern furnaces have a standardized cabinet width of either 14", 17.5", 21", and 24.5". Simply measure the width of the face of your current furnace to determine what width you need. Note: 14" wide furnaces are uncommon for most furnace & AC system configurations. If your setup requires a 14" wide furnace, please give us a call and our team will help you out.
Condenser Tonnage
An air conditioner's tonnage is a measure of how much cool air it can produce. Similarly to furnace BTUs, an air conditioner's tonnage scales upward with house sizes. Please notes that other factors may affect the ideal tonnage your house needs.
- 1.5 and 2 Ton - Ideal for small houses
- 2.5 Ton - Ideal for small to medium size houses
- 3 and 3.5 Ton - Ideal for medium houses
- 4 Ton - Ideal for medium to large size houses
- 5 Ton - Ideal for large houses
