"The very Worst customer service I ever dealt with. The first time they came out the guy didn’t even say two words to me. I had to ask all the questions he should have been talking to me about. My main problem was my fire place and he told me it was fine. Never even turned it on to check the problem I was telling him about. I Decided to have them order the part I asked for and fix it. Knowing what I needed. That was last week. They gave me appointment time for today between 2-4. 4 came around and no call , no one here, nothing. I called the office and tried to explain that Communication goes along way. I am Aggravated and Julie that answers the phones can care less. She don’t need to call, she don’t know when the guy will be here and tells me we can return the part and not come because I am aggravated. Not once did I raise my voice or curse at her!!! Ask to talk to the manager and he tells me oh that’s not Julie I will ask her and that waiting 2 hours with no phone call is not a big deal and neither is my fire place.. WOW I did curse at him at the end... NOT SORRY!! One thing if you are going to own a company and have people work for you learn how to communicate and have customer service.. And you wonder why your company has bad stars???? ?‍♀️?‍♀️?‍♀️ If I could have gave 0 stars I would.. This place is a joke!!!!!"

Heating and air conditioning services FAQs

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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

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.

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.
