Locating a good HVAC technician and knowing what to ask FAQs

Whether you're installing a new heating or cooling system or need an annual service, you want an experienced technician you can rely on to get the job done. That's why it's important to know the right questions to ask when locating a good HVAC contractor. Residential air conditioning contractors and heating contractors who employ NATE-certified technicians have fewer callbacks, ensuring you greater peace of mind.

Q: How do I find a good contractor/technician?

A: Ask friends and neighbors who they have used to repair their heating and air conditioning units. If they have used a contractor who employs certified technicians and received good service, then that contractor might be right for you. Use our contractor locator—and when you call, don't forget to request a NATE-certified tech.

Q: Is the contractor’s technician NATE-certified? How do I know?

A: Ask to see the technician’s credentials. You can validate a NATE ID number here. NATE-certified technicians carry a card which is proof that they have taken and passed the necessary tests. Many NATE-certified technicians wear the NATE patches on their shirts. NATE’s contractor locator allows consumers to locate contractors by postal or ZIP code. Ask contractors you find on the NATE site to send a NATE-certified technician, as sometimes the contractor may have both NATE certified and uncertified technicians working for them.

Q: What are the benefits of using a NATE-certified technician?

A: NATE-certified technicians have demonstrated their knowledge of today’s increasingly sophisticated heating and cooling systems by passing a nationally recognized test developed and supported by all segments of the heating, ventilation and air-conditioning industry. Consumers can rest assured that with a NATE-certified technician, they are getting the best installation and service for maximum comfort and economy in their heating and cooling system. Better installation and service mean a longer life for your heating and cooling equipment and increased energy efficiency. Technicians who are NATE-certified know that NATE stands for excellence and quality service.

Q: Is the contractor/technician familiar with my brand of heating and cooling unit?

A: When contacting a heating, ventilation, air conditioning and refrigeration (HVACR) contractor, be sure to identify your system by name. HVACR contractors and technicians are familiar with most current heating and cooling units.

Q: Does the technician or the contractor have liability insurance to cover damage in my home?

A: Ask the contractor. A technician or their employer should carry adequate insurance that would cover any damage done to your home by accidents while they are servicing your heating and cooling unit.
