"The HVAC in our new home has been problematic since day one until finally the heat pump quit. We called Airtech and they came in and identified the problem. Basically we had an over powered system with too many zones for the square footage and size of ductwork in the home. They installed a new heat pump, removed our electric backup heat and zones then coupled our heat pump to propane heat as the back up. Works like a champ now! Knowledgeable and easy to deal with."

"The fix was straightforward, had to replace the AC blower unit motor. Garmer handled the task expertly and with great customer service, despite them discovering an unusual screw installation from the prior owner which caused the housing removal to take a bit longer than they initially anticipated and first quoted (which, if you've owned a home, tends to happen somewhat often as equipment of this magnitude usually can be more complex than they first look). The only thing I would suggest is that they re-address their pricing. This job ended up costing around $1,200 to change a blower motor where the part itself probably was no more than a few hundred (final bill was delivered upon completion) - was estimating maximum $1,000 given their guidance throughout the job. At a certain point, it may make sense to give the customer a flat project fee as opposed to remain on hourly labor billing as the crew is trying to re-assess to avoid customer sticker shock and alienating future work. I respect the crew, the work they did, and value their labor, but believe the pricing is high. I would like to stress that I would recommend and would consider using them again simply because of their expertise, customer service, and responsiveness as they do great work, but would be more critical of the price ahead of time."

Heating and air conditioning services FAQs
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.
