What to Look for in an HVAC Contractor

Hiring the right HVAC contractor is a crucial part of any HVAC project. Whether you’re looking for an expert who can take care of HVAC tune-ups or installations, you have to ensure that they’re qualified and trustworthy.


Luckily, it’s fairly easy to find the right company for your job, especially if you know what to look for. In this post, heating and cooling specialist Custom Air Systems enumerates a few important things to check on when choosing an HVAC contractor.

Essential Documents

Find out if HVAC contractors in your state, municipality or county are required to obtain proper licensing. If they do need a license for providing HVAC services, make sure to ask for proof that the business is indeed licensed  and qualified. Check if they have worker’s compensation insurance too. This is important in case a worker gets injured while working on your property.


Ensure that your HVAC tech is trained and experienced at performing the specific job(s) that you need help with. Whether it’s HVAC maintenance, repair or replacement, they should have the necessary skills and knowledge to carry out the task. It’s also ideal to hire a contractor specializing in the particular brand or model of heating or air conditioning unit that you choose.

Track Record

It’s always a good sign if a company is able to boast of their track record of top-notch projects. This usually helps in alleviating any doubts regarding a contractor’s ability to deliver excellent workmanship. Of course, make sure that you’re not simply taking their word for it. Ask questions about their past projects, particularly those that are similar to your own project. This can be very helpful, especially if there are complications in carrying out the job, as it allows you to manage your expectations.

Written Estimate

Always ask a contractor for a detailed quote, and be wary of prices or deals that sound too good to be true. By taking these precautions, you can avoid falling victim to scams or unscrupulous businesses that aim to take advantage of your needs. As much as possible, get quotes from several different companies so that you can get a good idea of what’s a reasonable price for the job. Don’t hesitate to ask questions if there are vague fees included in the estimate.


Make sure to get all the details in writing. Don’t be satisfied with verbal promises; it’s best to keep all correspondence in email or text form so that you can keep track of what’s been said or promised. Ensure that all quotes and bids are made in official writing. Moreover, check the document for the following details:

  • a thorough breakdown of equipment and labor costs

  • project timeline

  • payment due dates

  • date of project completion


Ask your contractor for at least three referrals from previous customers, then call them up and ask questions about how the company conducts their work and communicates with clients, as well as the overall quality of their services. This way, you can learn more about the qualities of the contractor and figure out if they’ll be a good match for your needs. Additionally, you might want to check to make sure the business is registered with the Better Business Bureau (BBB). Checking the BBB website can often be a convenient way of learning more about the contractor’s reputation. Are they able to maintain a high rating for their service, or do they have outstanding complaints from customers?
