"I am a attorney in Nutley, New Jersey. We had no air conditioning on the second floor of our commercial building yesterday. After our regular HVAC maintenance company claimed to be too busy, we researched an alternate and found excellent reviews for Challenger. Access to our roof AC system is a bit tricky. It was no problem for Jorge of Challenger. He easily navigated the approach and the scuttle. The AC was in tiptop share in less than an hour, portal to portal. The price charged was fair and the work was clean and professional. Challenger has a "can do" attitude and approach to HVAC. Thank you Jorge for an excellent job. Based on our experience, I am very pleased to refer this company to others."

"I recently hired Kyle to service my central air conditioner. What a find!!!! I will absolutely hire him again. He is bright, personable and explains every step of his process. You can tell he is passionate about HVAC, and enjoys his work. He was able to quickly evaluate my system and get it back up and running. My system is old and really needs to be replace but Kyle was able to keep in running for another year... Highly recommend this company"

"Excellent HVAC and Solar installation services! They did a great job installing a new HVAC system for us a few years ago, so we sought their services again for Solar installation. They were very professional both times: provided pricing right away, technicians were polite, and job was completed in a thorough yet efficient manner. Jobs well done!"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

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.
