"They installed our unit in March 2015, and the unit induced motor was found to be defective in Nov 2015. They not only charged us for the service call but also charged us for the part which was under warranty. It was very unprofessional. The same part after less than 5 years failed again, and they took no responsibility for their workmanship. Customer service Person does not deal with the customer on the request. This time again they were charging us for the defective part and exorbitantly for the service call under the pretext that we did not sign a maintenance contract with them. So we did not finally go with them but went with another vendor who is far better and professional."

That's how you would describe our family of services here at Air Experts.

"Tech came out on Tuesday to service our furnace and look at duct work. Furnace was working but we could tell there was an issue. The tech told us that the diagnostics told him the furnace was ok but might need work in the future. 36 hours late our furnace stopped working. We called back and had the tech respond back out. They wanted to charge us another $135 service fee. Tech then found an issue with the capacitor and stated it needed to be replaced. Charged us $300 for a $35 part. The tech advised that the blower motor would most likely need to be replaced as well and quoted that at $2,290. 8 hours later our furnace stopped working again. The next day we hired a different company. They came out and advised it would cost $1,000 to replace the same. Before picking up the parts, the company checked and advised everything was covered under the warranty still and replaced the same for $350 in labor costs and service fees. The original tech made no mention of a warranty."

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.
