4 Qualities to Look for in an HVAC Service Technician

You depend on the HVAC system in your Alton, Illinois, home to keep you and your family comfortable throughout the year. When your HVAC system needs maintenance or repair, you want a skilled, reliable technician performing the work. NATE certification, industry experience, and dependability are some of the qualities you want to look for in an HVAC service technician.

NATE Certification

To receive certification through the North American Technician Excellence (NATE) program, an HVAC service technician needs to successfully pass several required competency tests. The NATE core exam covers areas such as safety, basic electrical knowledge, and temperature and humidity measurements. Completion of these tests certifies that an individual has the knowledge and skills to properly install and service HVAC equipment.

Industry Experience

When you need an HVAC technician, you want to be confident knowing that your technician has industry experience. Technicians should be able to tell you how many years they’ve worked in the HVAC industry and their areas of specialization. This latter item is particularly important if you need specific HVAC services, such as installing a geothermal heating and cooling system on your property.


HVAC emergencies can happen any day, at any time. When your air conditioner fails unexpectedly during a hot Alton summer evening, you want the peace of mind knowing that your HVAC technician will respond to an after-hours telephone call. A dependable technician will be able to respond to your needs promptly and professionally.


A professional HVAC technician must put the customer first. When you need a new air conditioner installed or your heat pump serviced, you want a technician who will listen to you, offer honest solutions, and carefully explain the costs of equipment and services.
