HVAC contractors are responsible for installing and maintaining all heating, ventilation, and air conditioning systems in the home. As such, they should have knowledge of the various HVAC systems available, from furnaces to heat pumps to ductless mini-split air conditioners.
If you're starting the process of choosing an HVAC contractor, don't forget to ask your friends and family for recommendations. Suppose you know someone who has had a positive experience with a particular contractor. In that case, it's a good idea to have them screen the candidate for you.
During the interview process, begin by asking about their experience with your type of heating and cooling system. For example, if you have a forced-air furnace, ask how many furnaces they've installed in recent years. Avoid any contractors with very little experience or expertise in installing your particular brand or model of the HVAC system; their experience will be very limited or possibly nonexistent.
Learn about the contractor's experience with your type of HVAC system.
How long has the company been in business, and how many technicians does it employ? A new company will be less likely to have highly experienced developers and technicians on staff. In contrast, an established company will be more likely to have those resources and a thorough grasp of the latest home heating and cooling technology.
In addition, take note of the contractor's level of customer service. Call the office for technical advice or help scheduling your installation appointment. You should get in touch with a live person right away. The same goes for scheduling future maintenance; a good contractor will schedule your follow-up appointments in advance.
