"Casey with JM did an amazing job! The old ceiling fan we wanted to replace had an unusual setup that I was worried would make for a complicated job of installing the new one, but he took care of it without a problem, and even mounted the new fan?s remote on a blank outlet slate as shown. I couldn?t be happier with the results!"

Apple Aire is well known in the area for their superior quality workmanship and commitment. Unlike typical HVAC's who simply want to install the unit and be done with it, your Apple Aire technician will diligently consider all factors, including energy efficiency and weatherization to select the most appropriate unit for your home. If you're looking for excellent customer service and an experienced, reliable team for your next HVAC installation, look no further than Apple Aire.

"Apple Aire came on time and installed the new boiler and water heater and removed the old one with as little damage to the house and mess as possible. When my electricity went out the next day on the same circuit as the boiler, they sent an electrician who fixed the problem at no cost to me. I recommend them highly."

Heating and air conditioning services FAQs

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.
