When you need work done related to your HVAC system, you’ll want to choose a company that you can count on. Sometimes, that’s easier said than done. How can you know whether a company can be trusted? You may be better off if you look for the following things.

Proper Credentials

There isn’t a nation-wide standard for HVAC credentialing, but many areas do require licenses. In addition, many established and reputable contractors will be certified through an organization such as NATE (National Association of Technical Excellence). A company should also have insurance, just in case anything goes wrong. Insurance protects the HVAC technicians and, more importantly, you. It’s perfectly acceptable to ask an HVAC company about its license and insurance. Often, companies will have these listed on their website.


People in the industry are used to getting asked for references. It may feel a bit awkward to call someone you don’t know about their experience, but fortunately, a lot of communication can be handled online. Many websites have reviews available for you to read. Asking friends, family members, and neighbors about their experiences can point you in the right direction as well.


When you interact with an HVAC company, make sure you’re being treated with respect. Communication should be clear, technicians should show up on time, and your questions should be answered promptly. When you get a quote, feel free to ask what the payment schedule is like and whether anything could change the price estimate. If you don’t get satisfactory answers, you might want to keep looking for a company.
