1. Choose the right brand.

You may be wondering what brand is the best, and the truth is that most brands are perfectly fine. However, we recommend you stick to the familiar once like: Rheem, Lennox, Carrier, Bryant, Trane, Amana, Ruud, and Payne. The reason familiar brands are a good option is because all technicians will know how to repair them and can easily find parts from nearby suppliers. All top manufacturers also sell through contractors, allowing you to buy a great brand for a great deal!

2. Decide if you need to focus more on cooling or heating.

Cooling is measured by SEER (Seasonal Energy Efficient Ratio) and heating is measured by AFUE (Annual Fuel Utilization Efficiency). If you live in a cooler climate, you will want a highly efficient AFUE rating (between 90 and 97) and a basic 12 SEER cooling condenser. Make sure you are aware of AFUE and SEER ratings before you make a purchase! If you are confused, ask a professional.
