"I put in a whole new HVAC Trane system 2 years ago, and signed up the the twice a year maintenance program. So far, the technicians who come to inspect and examine both the heating and cooling systems have been very competent and thorough. Yesterday, Dave Seible was my technician and he was great. He also had filters available, so I bought those too. Very good and professional operation."

"Extreme Heating and Air Conditioning installed an 18 SEER HVAC system with zone control for me. I am very pleased with the results and performance of the system - far better than the previous system WRT air flow balance. All personnel were very knowledgeable and professional and I highly recommend this company. Thanks to Tristan, Brett, Ryan, Joe, Paul and special thanks to Dave and Tyler for working through some parts failures. I am very pleased."

"Hauserâ s sales manager and the field tech were both Very polite, knowledgeable and clearly communicated in as much technical detail as I wanted the repairs they recommended and why. Our previous HVAC service provider had diagnosed loss of AC cooling as a compressor failure and had quoted compressor replacement at over $3500 or even recommended replacing the matched AC & Evap Coil unit costing $5-$7K depending on the efficiency chosen. I approached Hauser for a second opinion diagnosis for loss of AC cooling and they diagnosed it as a deteriorating but not failed compressor and had it running in half an hour with a new replacement run capacitor and an add-on electrical gizmo â compressor saverâ at total cost of under $400."

"Our technician called to let me know he was running behind by about an hour. He was very apologetic and professional about the inconvenience. When he arrived he was very professional and got right to work. After servicing our unit and going over all the testing results with us, he made sure we fully understood everything and were comfortable with the results. He was great with our twin toddlers also, who were very interested in what he was doing. Even though it was late and we were his last stop of the day, he stayed and chatted with us and answered all our crazy HVAC questions that had nothing to do with what he was there to do. He was very knowledgeable about his field, was very friendly, and did a great job cleaning up our AC unit. It is running more efficiently now, and I'm sure we will see the results in our upcoming bills! It was an excellent experience and we will definitely use Wells for our future HVAC needs.

"Riley did a great job on a new gas furnace and air conditioner install. I was very impressed from start to finish. He was on time, professional and answered every one of my questions. My system was about 15 years old and I have had to put some money into over the years. I used several other companies during that time and none of them, I mean absolutely none of them, compared to the process I just went through with TrueTemp Heating and Cooling. Everything from the service call, to the consultation process and the installation of my new HVAC equipment was top notch. Can?t recommend this experience enough! Thanks TrueTemp!"

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.
