"Terrible customer service He created giant messes and lied to me on multiple occasions. I will say anything to get the project and not actually answer questions. When they came to give the quote, I asked them where they would put the heat pump and I said behind the house, but when they went to install it, it would not fit behind the house according to code. I constantly had to hound them to finish the job. They started in the spring, and then they did not finish until the winter, after saying they could start in 2 weeks. They left me without heat on below-freezing days because they were not finished. They did not honor parts of the contract. charged for service even though the contract says it is free for 3 years. They tried to charge me for things they did not install(humidifier). Installed the ventilation system over some sill rot. I left gaping holes in my home for months. I had to hound them every step of the way to get them to do the next part of the project. They were replacing propane and oil with gas and did not tell me I had to remove the propane to do so, and then the town would not permit their work and I had to pay out of pocket for more conversions. I had to hound them to get permits, including an oil tank removal permit, which they never pulled and I still do not have! The end result was an expensive system that I think is misconfigured and ill-fitting for my home (it does not remove humidity properly). If you would like to do the project management yourself, hire this company. That said, there was one very nice technician, but I would not have them install anything."

"I am genuinely flabbergasted that this company has so many five star reviews. From the marketing practices to their customer service, my frustration with them was pervasive. The work they did seemed to be fine enough, but it was overpriced (I later discovered) and their communication at several stages was just abysmal. My attempts to have them remedy the shortcomings of their process gained no satisfaction. It also left a really, really bad taste to discover that their signs plastered all over the furnaces and water heaters in the basement of our condo building was not because they had some kind of relationship with the condo *and in most cases had no relationship with the equipment that their signs were on*. Just obnoxious. To top it all off, someone my email address was leaked from their organization which led to it being the target of hacking. How would I know it was them? They were the only company that I had given that particular email address to, Then they had the nerve to ask for a customer testimonial video. As if. Would not do business with them again."

The technician arrived on time, knowledgeable and walked me through the entire process. Open communication, no hidden fees, did not fix items that were not broken, honest with issue and pricing. They were here to fix the problem and not to give a sale pitch. I would HIGHLY recommend and will be using them again for yearly maintenance."

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.
