"Awesome job!!! I called several HVAC companies before contacting Cody. Cody explained all the technical aspects of my issue and even defined the technical terms I didn’t know on the initial call. Not only did he help me understand my problem more clearer and help guide me down the various routes I could take to remedy them, he quoted me almost 50% lower than most companies. After agreeing to the service, he was able to perform the service the following day to restore my AC. Upon arrival with his crew, I asked him how long did he think it would take. He said an hour. It took 1 hour for him to install my new AC. After a week of guys trying to rip me off, Cody and his crew reconfirmed my faith in honest service. I absolutely would use them again and would refer them to anyone needing any kind of service. Excellent service. Very professional. More than anything, HONEST!!! A++ if I could rate it. They should be the ones you call if you need HVAC work!!!"

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.
From average costs to expert advice, get all the answers you need to get your job done.
