"I called them based on reviews on Angie's list. They were very responsive and quickly came over to look at our older air conditioning unit that was not working. They said that while they could repair, it was better to replace it with a new one because the unit was too old and repairs could not carry warranty. We agreed. The price quoted was reasonable. Richard and a co-worker did the work. They replaced both the AC and furnace units (Trane) with TempStar. Overall, we found Cool Air team to be professional and knowledgable. We have not yet used the AC given the weather has been nice but we will in summer for sure! There is 1 year warranty on labor and 10 years on the unit."

"Bob Jenson sent 2 installers to put in 3 more mini splits this past Monday. Tony Guardarrama and Pouria arrived on time both Monday and Tuesday. They did an excellent job and I am very satisfied. It was not an easy installation, but they somehow managed to get it all done and no messes were left behind. I wholeheartedly recommend Bob Jenson AC & Heating."

"Service man arrived as expected and performed the annual maintenance of the air conditioning system. The work was thorough and it was something that was familiar to me as I used to do in my younger years. With heavy use of airconditioning in the summer in CA, this is important and something we do every year.

"Noticed one of my bedrooms wasn’t getting the same air pressure as the others. I called the guys at sky clean air and was scheduled for the following day for a free quote. Nadav and Erick were on time and quickly got to work, because the age of the house the duct connected to the spare room had become brittle and damaged. I was given a quote for the single duct and replacing the attic I was never pushed into making a decision. Ended up going with the single duct and work was done same day with before and after pictures. My experience with Sky Clean Air is the type of business you want to deal with never felt like I was being played. Definitely recommend"

"Brandon from Airtime handled our AC issue quickly and was a complete pro. We really needed our AC fixed before the summer heat starts. He diagnosed the problem and gave us a clear description of the issue and the process he would need to take to fix it. He was professional and not to mention kind. We would hire him/Airtime again in an instant."

Air Conditioning questions, answered by experts

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

A one-stage air conditioner only has one setting, while a two-stage air conditioner has a high and low setting. A two-stage air conditioner costs between $500 and $2,500 more than a traditional air conditioner, but it has a longer lifespan and helps to increase energy efficiency. To make this decision, you should consider your energy needs and available budget.
