"Gordon, Harrison and Louis did an absolutely fantastic job with installing a brand new HVAC system into my old house. The house was not designed to include AC so they had to be very thoughtful in the process of figuring out the best way to install all the equipment. They were on time every day and always kept me informed any issues and next steps.. They did it and we will enjoy the benefits of keeping cool this summer."

"We just had a new HVAC system installed in our home in Aliso Viejo. The contractor was Cool Air Technologies, Bill McIntosh, (714)863-0626. We were very impressed with the new unit put in the attic and back yard, the workmanship, the professionalism, the quick response time to get our appointment, the testing of the new units before they left, the lessons for us on how to use it, and the complete clean up and hauling every piece of the old unit away when they left. They even installed new air vents/registers in every room and air filters! Very impressive and highly recommended to everyone! [*** Link removed ***]"

"Great. My daughter contracted Air Duct Professionals to do her home. James, the technician, was professional, knowledgeable and did a quality job. I contacted Air Duct to do my home and requested James. James arrived on time and did an excellent job. He also helped me with a leak with my HVAC Condenser and diagnosed and fixed the issue."

"Sam, who came out to give me an estimate for a new system, found out that the old fan motor was the culprit and recommended that we just repair the motor. He explained things in detail, helped us to save money in a genuinely sincere attitude, I was impressed how good his service was, and I recommend him for any HVAC issues. I will be using him in the future."

Heating and Air Conditioning questions, answered by experts

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.
