You've Clicked Canella!Mon-Fri 7:30am-9pm  /  Sat 8am-4:30pm


We polled a few people to find out what would help them choose a heating and air conditioning contractor. There were only two questions they really wanted to know.

Question 1: "How long has your company been in business?"

In 1990, Craig Canella founded his heating and cooling business in Bethlehem, NC. A few years later, his brother Curtis joined him and they have been serving Hickory, Conover and the surrounding areas ever since.


How Does That Benefit You As A Customer?

  • These guys have many, many (don't tell them I emphasized "many") years of experience in heating and air conditioning. This has never been a side job or a hobby for either of them. It’s their career and its how they continue to support their families.
  • Not everything is made “better” by selling out to "bigger." Craig and Curtis still own this company. And we still believe in hometown service.
  • We don't just install systems and disappear. We have a Service department and a Maintenance department with technicians who specialize in each of those fields. We’re here to take care of your equipment for as long as it lives.
  • We own our shop, not just a van and a removable sign. Selling a shop and skipping town in the middle of the night is a lot harder than selling a van or removing a magnetic sign. (Plus the family isn't too keen on moving in the middle of the night either.)

Question 2: "What are your qualifications to do this job?"

Canella Heating & Air Conditioning is licensed in North Carolina to install and repair heating and cooling systems.

Installing HVAC equipment in North Carolina requires a license that's issued by the State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors. To get one you have to have at least five years of experience and pass a difficult test. Our license number is 15525, H 1, 2 and 3 which allows us to do HVAC electrical, plumbing and heating.

The Board invites you to look up anyone's HVAC license or talk with them about the performance record of any company you are considering using. The phone number is 919-875-3612 and their web address is

How Does That Benefit You?

  • If you have trouble with your new equipment and can’t get the situation fixed by the HVAC repair contractor you hired, your options for help are limited if he was unlicensed. Sort of like when you buy stereo speakers out of the back of a car in a dark alley – if they don’t work, good luck getting your money back. And you became a victim because the last person who bought speakers from this guy couldn’t report it either.
  • One of the board’s jobs is to make sure contractors meet at least some minimum qualifications. Your new system is supposed to keep you safely comfortable for the next several years, not to mention the fact that it’s a major financial investment. With that much riding on the qualifications of the person installing your system, it should be worth a five minute phone call to verify that they know what they’re doing and have done it well.

We use only certified technicians


Service Technicians don’t need to be certified to work in heating and air conditioning, but ours are. They’re certified by North American Technician Excellence, Inc. ( NATE is the country’s premier certification company for heating, ventilation, air conditioning and refrigeration technicians.

In addition, all of our employees are required by our company policy to take continuing education classes every year, even our office personnel.

How Does That Benefit You?

  • Our technicians are trained by professional instructors on the right way to do things. They’re not doing it just because that’s the way it’s always been done or learning from someone else’s bad habits.
  • Our continuing education requirement means our people are staying up-to-date. The technology in this field is constantly changing, like most things. And like most things, you either keep up or quickly fall so far behind that it’s difficult to ever catch up. Simply put, you can be confident that the HVAC repair contractor who visits your home is a true expert who will keep your best interests at heart.
