2. Buying an HVAC unit is not an easy task, especially if you know nothing about it.

3. Consider and understand the ratings because only then you will be able to make the best choice for yourself.

4. The AFUE rating indicates the efficiency of the system and the percentage of fuel it is going to use.

5. The indication of the heat pump efficiency is displayed with the help of the HSPF rating. SEER determines the efficiency of the heat pump and air conditioner; with a higher rating, the efficiency becomes better.

6. One must also consider the initial price as well as the long-term costs involved in an HVAC unit. Always choose such a contractor who has knowledge and expertise regarding this subject and easily guide you to make the best possible decision.
