Our reputation is based on service, safety and quality, regardless of how large or small the job.

"My husband and I recently installed AC in our San Diego house. If youâ re a longtime local, you know how necessary it is these days. We struggled through the last few years with portable units which we installed in all our bedrooms, but they were bulky and loud. About 2 years ago, we started getting quotes. Every quote was between $12,000-$15,000. It was really shocking to learn how expensive air conditioning is. We were later told by a friend that the high cost is partly due to demand. We decided to save up money for it, and continued asking friends and neighbors for referrals. Finally, we were referred to Ulises Castaneda at Heating and Cooling Aid. This is Ulises' own company, and while heâ s small, heâ s extremely professional. He came out and explained why our house was not a one-size fits all solution, and recommended a mini-split system. We live in a canyon, and our house is not on flat ground all around. And the best part was his price was very competitive. We scheduled the job and over the course of 2 days they installed the system. He took care of the permits, and inspections. It was very easy. They also cleaned everything up well, and it was hard to tell they had been here. The system they installed is manufactured by Daikin, and it is unobtrusive, and very quiet. We are extremely happy with the outcome, our sleep has been fantastic, and we can highly recommend Ulises and his team."

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.
