How to Choose a Reliable HVAC Contractor

As a business owner or manager, you expect your heating and cooling system to provide comfort to your occupants. Any interruptions can negatively affect productivity or your bottom line, which is why it’s crucial to find a qualified HVAC contractor in the case of an emergency. With 39 years of experience providing commercial HVAC services, the experts at Del-Air Mechanical know what a reliable contractor looks like. Employ these tips before you employ someone to handle your heating and cooling system.

Research, Reviews, & Referrals

Follow the three Rs when doing your initial search for an HVAC contractor.

Research- A quick online search can help sift out any subpar companies. You should also be on the lookout for the amount of experience, an up-to-date website, and accreditations.

Referrals- Utilize your friends, family, and network to get insight into their experience with a particular company or contractor. These personal recommendations from your trusted circle can help lead you in the right direction.

Reviews- 4 to 5-star reviews are typically a good indicator of quality work but you also want to be sure to read what people are writing. Were their problems swiftly and efficiently solved? Did their contractors go above and beyond to help them?


Many states require contractors to be licensed. Fortunately, many government websites allow you to search them up to check their status. If you are located in Tennessee, you can verify a license here. At Del-Air Mechanical, we make sure our license number is clearly visible at the bottom left corner of our website.

Get an estimate

After you’ve narrowed down your options, it’s best to obtain at least three written estimates. Your HVAC system is made up of complex technology, which comes at a cost; so, you must choose a contractor carefully. If you notice a large disparity between estimates, then there’s a chance they might be using substandard equipment. While it may seem tempting to go with the lowest price, be wary.
