When air conditioning units begin to lose their effectiveness or stop cooling altogether, it could be the sign of a refrigerant leak. Refrigerant (or freon) is a chemical which is present in the unit to cool the air which enters your home, and without it you won’t get relief from the summertime heat.

Our company specializes in all things heating, cooling and ventilation, and we frequently help people in the East Bay Area when their units have freon leaks. If you suspect a freon leak in your system, we want to help. Check out these FAQs about our leak detection process and learn more about how we can get cool air flowing back into your home.

What are the signs of a refrigerant leak?

Since freon is the chemical that creates cool air, when it has lower levels inside your AC unit it will take more work from the unit to cool your home. If it seems like your unit just can’t catch up to the desired temperature you’re seeking, the cause could be a lack of freon. As the freon levels continue to drop and the unit works harder to cool the home, ice will begin to form on the lines connecting the unit to your home. In this case, there is a major lack of freon. 

What should I do if I suspect a leak?

The added stress of constantly running can put stress on your unit and can cause issues with other parts of the system. If you think you might have a freon leak, the first step is to check for ice on the lines which connect the unit to your home. If you notice ice present, it’s best to shut off the unit completely. When this happens, the ice must thaw before it can be repaired, so by turning off the unit and then calling our team, we should be able to begin work as soon as we arrive.

What is the process of detecting an air conditioner leak?

Our team has the know-how and equipment to detect leaks efficiently. We first check connections along the lines to ensure they are tight and there are no gaps. We also use special dyes which can alert us to the existence of a leak. If there is still no leak detected, we pressurize the system and use our specialized equipment to locate its source.

How long does the leak detection process take?

We work as quickly as possible and some leaks are easier to locate, and most are located within about two hours.

What should I expect from my AC tech?

We take a customer-first approach to everything we do, so you can expect a courteous, professional, and experienced tech to help you. We also take pride in our work, so rather than offering the “quick fix,” our team wants to provide a lasting solution to your issue.


I am a real estate agent and Will put in a new furnace for one of my clients. He did a great job and they were very happy with his work.

Mike D.

Will is experienced, reliable, and a great communicator. I hire and refer him whenever I get a chance!

Bethany O.

We had two other guys come out and couldn’t figure out the problem.Will figured it out right away. Will made us feel very comfortable. He always communicated every step of the way and we are very happy with his work. I would recommend Will to everyone I know!

Amy M.

My experience with Cozy Conditions was amazing. The quality of the product was second to none. The work was done very efficiently and without issue. I would recommend them to anyone.

Benjamin B.

Will is as good they get! He knows his stuff and is as fair and honest as they come. He’s a true family man who works hard for not only his family but also yours!!!


Will was very professional – he explained all the details and worked efficiently. The price was awesome too.

Francisco E.

Will replaced a furnace for me located in my basement. I was pleasantly surprised on how neat and clean the installation went. No issues and the furnace works great. I will have Cozy Conditions back this spring to do a service check on my AC.

Denise M.

We would gladly hire Cozy Conditions again for a project and would recommend them wholeheartedly. The work was done with care, they kept their commitments, and the work area was tidy and orderly.

Michelle L.

It was time to replace our existing unit. We got several bids, and so happy we went with Will. He was very informative, honest, and we really appreciated that. The timeline/install was exactly what he had said. I highly recommend Cozy Conditions! Thank you Will!!

Kimi L.

After screening several contractors and well-known HVAC businesses, it was clear to me that Cozy Conditions was the best overall value. I received daily updates on the progress of the job and Will always checked in to make sure I didn’t have any questions.

Clifford H.

Will not only did an excellent job of both my installations, but also charged me a rate which was extremely reasonable. He installed a mini-split system on the roof of my office building and an exhaust fan in the men’s restroom. He is now my regular HVAC tech.
