"I absolutely recommend Alanis Air to my friends and neighbors. They are a local, family-owned, family-centric business that knows their stuff. Tony did a great job eying out our 1961 Clairemont house and gave us an all-inclusive price. Their competitors would have charged an extra change-order to replace the 60 year old ducts for sure. Two days after shaking hands, the installers replaced our heater, added the new A/C unit, replaced the air ducts and fixtures, and connected it all to our Nest all in one day. They even scheduled on a Saturday, to not interrupt our work-from-home and school-from-home schedules, were extremely courteous, cleaned up as the job went on, and wore masks the whole time. It could not have been very comfortable to wear a mask up there in our tiny crawlspace! When it got warm the next weekend and the A/C magically kicked in... bliss. THANK YOU Team Alanis!!!"

"Had them do 2 units on my property. The first one was great, the pre team is great, and the guys who actually do the work. After the 2nd one, where I chose the more expensive option to get a Mitsubishi Heat Pump, the unit would not turn the fan on some of the time. I told them, and wasted insane amounts of time. They kept saying things like 'I am trying to understand what doesn't work.' 'Pretty simple, you choose to run the fan to simply circulate the air and the icon goes, Nest thinks it is on, but does not go on.' Then they said they were going to have a Mitsubishi tech come out and for sure it would get resolved. Never happened. Just listened to a book on Benjamin Franklin and he and John Adams had to share a bed one time while traveling and Adams went to close the window and Franklin said this place will be a tomb if you do. That was what 250 years ago? and HVAC is their business? Guess I will have to take them to court. The office staff post job is a clown car of silly children. So if your job goes great, they will be a good choice. If you run into an issue you will wish you hired ANYONE else. You've been warned."

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.
