"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."

"they initially quoted $89 for AC diagnostics which is reasonable even though most companies charge nothing. Technician is very friendly and knowledgeable and walked me through the process. he checked the compressor outside and he suspected a leak. and then wanted to check the coil inside the blower. he detected a small leak with the electronic device. he mentioned coil may need replacement. After spending 10 mins in his truck to call the company he came back and said coil is not covered with warranty and quoted $5,400 to replace the coil and it is backordered for 6 weeks. 6 week will brings us to mid August so i told him i dont want to sign up for repair and wait 6 weeks. he then tried to sell me a maintenance plan which i declined. Then he said he will charge for the diagnostics which he spent total 30 mins including talking on the phone for warranty coverage. he said he did more than basic diagnostics which is $149. when he handed me the payment he added up initial $89 and $149 to pay $238 for 30 mins diagnostics. Total scam. i dont even know if they do any real work beyond the charging $238 for 30 mins diagnostics. probably they will hire a separate contractor to do the job and keep selling overpriced diagnostics and maintenance plans. They all you 10 times to sell you the initial diagnostics but after you pay $238 not even a single call to ask about experience. worst ever."

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.
