"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

Local family owned air conditioning company with 25+ years of experience. I offer free second opinions on another company’s diagnosis of your system. No overtime charge. Free estimate on equipment change outs. I do air quality testing for your home or business. Dehumidification, solving airflow issues, repair or maintenance, system design, I can do it. Give me a try, I won’t let you down. Chris Rattray @Aire Serv

"Our system was not cooling and we needed it checked for all issues that could be causing it. The technician did incomplete checks and declared the issue was just that the plug was not in place, he did not give us an estimate for approval, he directly billed us to pay $275 for putting the plug in place. After a few days the issue with our cooling reappeared, he came back and mentioned there could be leak but refused to check where the leak was without another payment. When he came the first time he should have at least checked our system properly for the $275 he charged us. They just declared everything is good without even checking with the meter."

Heating and air conditioning services FAQs

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.
