"My service technician, Mason, arrived on time and got straight to work. He was very thorough and explained everything that he was doing as he was doing it, and prior to doing it. He arrived with another associate, and both men were very nice. I like the fact that they’re thoroughly explain everything and don’t try to pressure you into buying anything at the very end. He fully explained that in a few months I would be due for another filter, but that everything else was OK. He also explained what would happen if I did not change the filter which was helpful. I would highly recommend Cardinal if you are in need of heating or air conditioning repair or service."

"This was amazing! I had no idea this service existed. After searching and contacting various repair places for my washer, this was the most cost effective option. I figured if it didn't work, my machine is old and I would be out $40, not the $100+ to have a tech come out and just diagnose the problem. I am pretty handy and my washer is old anyway, so if it is broken, I have to get a new one anyway. My tech, Steve, was great! He predicted what was wrong after listening to the machine, calmly walked me through dismantling the machine and when we got down to the motor, he was right! He sent me a link to the part I would need, and let me know to contact them again if I needed help installing it. My machine works even better than before it broke, its beautifully quiet and efficient. I will definitely be saving this company for any future repairs on appliances I may need. The service was $40 + the part cost, which was about $8."

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.
