"Very pleased with the finished work. Donny did a great job with everything, he really knows what he is doing. Put a new service entrance in, new breaker box in the basement, fixed up an old dryer plug and some new wiring. I have a few other smaller projects and he will be my go to guy. Thanks again Donny."

"Called Josh on a Saturday morning to report a problem with our heat pump by noon he was here and had identified the problem. We are very happy with this company as they do not use a 1000% markup on parts like some HVAC companies in the area seem to charge. With Air Adviser you get Honest service at an Honest price."

"They were a bunch of super nice guys and they were both very kind and quick to get the job done. I felt that they had my family's best interest in mind and they were always up front with price quotes so there was no surprises. I will definitely have them come out this fall to continue with fixing some ducts. They were very professional and very polite. I would recommend them to anyone! I was amazed at how skilled they were in many areas of home maintenance and they gave me good advice on how to improve the efficiency of my furnace and AC. Thanks again!"

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
