"Also known as 'Gee HVAC Services', which is the company I thought I hired. They had 5 reviews and had 4 stars so I was fine with that. I only noticed that it was Granty's Topline Services when we got our receipt. We called initially to get heating fixed in an extension room. After they came the heat in the whole rest of the house went out. That's when I checked the receipt and then realized that this is not the company I thought I hired. When I found them on Yelp I thought they were Gee HVAC Services. That's when I saw the 1 star reviews and realized we were scammed. We literally paid $600+ to have our heat broken in the entire house. On top of that, after we called to have him come back and fix it, the heat was on in the house, but 2 hours later there was smoke coming out of the boiler room and water was EVERYWHERE. He said it was because we needed to change the water valve, but this problem didn't happen until he came to break it. I am now in tears and it is going to be 9 degrees tomorrow night and I currently have Covid. This has been an absolute disaster. Edit: I came back to do an update since we finally got a legit HVAC person in to fix the mess Tony made. First of all, he didn't do a tune up. Or at least the guy who fixed this said it was the shoddiest work he's ever seen. Secondly, he almost killed us. He bypassed the controller and hooked up the boiler to the always on mode, so pretty soon there was steam coming out of our boiler room and it was chugging out boiling water. It eventually would have exploded. I am considering any legal action I can and will review on every single site I can to warn people to stay away. This man is a crook. Also, my husband told me when he was first here and was looking at the radiator in a different room he had water spewing everywhere. I didn't know this at the time because I was sick in bed with Covid and my husband didn't want to upset me. Absolute disaster. I was fooled by the other business name he 'works' under (really steals)."

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.
