An average HVAC system has a lifespan of approximately 15-20 years. Around this time parts start breaking down, efficiency drops, and the entire unit could be in danger of breaking down. Replacing individual parts is rarely a good idea. You may need an entirely new unit. HVAC units are expensive installation isn’t easy. When it comes time to buy a new HVAC unit, you are going to want to be well informed so that you can make the right decisions.
Choosing the Correct Size
One of the first things to consider when shopping for a new HVAC unit, is size. A unit that is too small will not be able to meet your heating and cool needs. Some rooms of the house may never even receive cool air! Buying a unit which is too large would just be wasteful. A contractor can perform something called a “load calculation” which will determine what size HVAC unit you need.
Consider your Home
The next thing to consider is the specific needs of your home. Do you live in Arizona where the winters are mild but the summers are devastating? Perhaps you live in the Michigan and face brutally cold winters. You may need a heat pump with a backup boiler if that is the case. If you have any questions, it is always best to contact a qualified service professional.
You have determined your needs, but there are still a few more questions to ask. How concerned are you with energy efficiency? Units which have been highly rated for energy efficiency may be a little more pricy upfront, but you could save a good deal of money in the long run. You also need to hire a qualified technician. Look for what that has been NATE certified. The NATE certification is given out to those service professionals who have achieved absolute mastery in the realms of heating, cooling, and ventilation.
