What to Look for in an HVAC Contractor

At Oliver, we know trying to decide on an HVAC contractor can be tough – you want the best equipment, but don’t want to be overcharged. You also want to talk to friendly, knowledgeable technicians who have experience and can get the job done right. We’ve put together a little checklist to help you know what to look for in a good contractor:


When someone discovers an HVAC contractor they can trust, they often stick with them, so ask your friends or family for recommendations. If they’ve found a great company, they won’t hesitate to let you know.


A good HVAC contractor should abide by regulations, so look into your state and local codes and regulations to make sure the one you’re considering does. Then, ask questions – ask to see their license or ask for the license number. Also ask about their business insurance and workman’s compensation insurance, both of which they should have for safety reasons.

A Written Estimate

HVAC contractors should have no problem giving you an estimate in writing for your equipment and their services. If they don’t (say they only offer you one over the phone), take it as a little red flag and talk to another company. Also, getting estimates in writing makes it easier to compare them and choose the best one.


A good HVAC contractor should be able to assess your situation, review all of your options, then help you decide on the best solution for your home and your financial status. If you have any questions, don’t hesitate to ask – a knowledgeable technician should be able to answer.

NATE Certifications

A trained and qualifiedHVAC technician should have completed a program offered by the North American Technician Excellence Inc. and have gotten a NATE Certification. Make sure the contractor you want to hire employs technicians with these certifications.

Customer Service

When you talk to an HVAC contractor, pay attention to the way you’re treated. If they are friendly and you’re treated well, it’s a good sign that that’s how you’ll be treated if there’s ever a problem. On the other hand, if you’re not satisfied with their customer service, find someone else so you don’t run into problems later.
