"Air Synergy is an exceptional HVAC company that I would highly recommend to anyone in need of a new system or maintenance services. I had the pleasure of working with Mario and his team of four, who were all incredibly friendly and professional from start to finish. They arrived promptly on time and completed the installation of my new furnace and AC in a timely manner, ensuring everything was working perfectly before leaving. Alberto there also provided me with recommendations for a new thermostat that would work well with my new system, which I really appreciated. I ended up taking his advice and have been very happy with my purchase. The system has been working great since the installation and I can already notice a difference in the air quality in my home, which is a huge plus. One of the best decisions I made was purchasing the maintenance plan offered by Air Synergy. It was affordable and provides peace of mind knowing that my system will be regularly checked and maintained by their team of experts. They even cleaned my ducts during the installation, which was an added bonus and something I hadn't considered before. Overall, I couldn't be happier with my experience working with Air Synergy. They were very easy to work with, listened to my needs, and provided exceptional service throughout the entire process. I would definitely use them again in the future and highly recommend them to anyone in need of HVAC services."

FAQs for heating and air conditioning service projects in Brentwood, CA
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.
