"I scheduled service using their online tool. After my service window expired without a technician showing up, I called and was told the online scheduling tool wasn't up to date and let me schedule an appointment that was unavailable. They said they had called the previous night to let me know, but I have no missed call and no voicemail from them. They offered to reschedule me for a full 5 days after my initial appointment which I declined. They made no other effort to make up for their mistake."

"I have a mixed review. There was an initial site survey done by Ron M. He gave me estimates of $48k, 23k and 13k. I almost walked away from my new Electric vehicle. I had to suggest the option I went with, to replace my electric range with a gas line run to install a gas range in my kitchen. I did so at a cost of $890 for the range and $1508 for the gas line. Before we settled on this bid, I asked about the former hot tub that was behind my garage. Ron didn?t listen to my input and said it was probably 110v and I asked since my house was bought by me from my Mom when my grandma died. I knew that it was heated and had a 220 circuit. Ron was not the installer on the day of the install, the two gentlemen that did the install did GREAT WORK! 100%! When they were done, the older electrician told me that there was good news, after me spending $2400 for a new gas stove and a gas line, that they used the hot tub line to install my EV charger Ron didn?t listen to a word I said cost me more$"

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.
