"In the middle of a heat wave my AC broke down during the night. I called a company I have used previously, but they weren't able to get to me for at least a week. While searching for a repairman using an app Circumvent contacted me and would come that day by 6 pm. The technician was able to come earlier. He found the issues right away and was able to repair my AC in less than an hour. The price was fair. He explained everything to me before proceeding."

"torn between 2 &4 stars but went with 2 only because I feel the cost exceeded in my opinion a reasonable cost to replace with a basic 40-gallon electric hot water heater based on the cost I paid two months ago to have a new eclectic 70-gallon high efficiency heat pump water heater and expansion tank installed. We had no time to shop around.... 4 stars for the prompt repair and 2 stars on the pricing."

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an uncertified HVAC pro could lead to poor quality work, costly future expenses, and potential code violations. A certified HVAC technician tackling your home projects protects you as a homeowner.
As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified 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
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.
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.
