If every repair and maintenance company were as good as these people, it would be a better world. I’ve used them on two occasions for different problems with my HVAC system. They were very thorough in searching for the causes of the trouble, and they were able to correct the problems in short order, even though these were not simple issues. They showed me steps I could take to prevent recurrences and to improve the operation of my system. At no point did they try to push for extra, unneeded services. Simply the best!

1st off, I have to apologize for taking so long to to write this review. I’ve been really enjoying my new heater. Cool Air Technologies installed a new heater and air conditioner in my home last month and they did an amazing job. The crew showed up on time and removed the old heater, installed the new heater, air conditioner and all new ducting in one day with two people, it was estimated as a two day job. They were incredible. Friendly, courteous and hard working. I would STRONGLY recommend this company for any HVAC work.

Thanks to Bill, Trish and all the crew.

I have used Bill Mcintosh and his team at Cool Air Technologies for years. He has prolonged the life of my original AC unit for years and this year installed a whole new HVAC heating and cooling system, which I absolutely love. Bill and his team are professional, knowledgeable, always answer the phone, they respond quickly, and always take care of my air conditioning and heating problems. You can rely on this team. I will continue to use them and I highly recommend them to everyone!

A handful of years ago, Bill from Cool Air Technologies, came out and had our furnace and AC replaced. We were very pleased with the whole install.

OK, now we added some substantial sq. feet to our house and needed an upgrade for the additional footage to our home. Bill again came out and we went with the EQ he suggested. The techs, Miguel and George, worked through the day and the install was complete. This crew was very professional and cleaned up like they were never there. Except for a very, very quiet system. I would have added the footage earlier if I knew the newer EQ was going to be so much more quiet and efficient.

Again, thank you Cool Air Technologies.

This is a five star company to say the least.

This is the second time I’ve had the opportunity to work with Cool Air Technologies and I couldn’t be more pleased. Seven years ago they replaced my whole system and it’s worked perfectly every since. They recently replaced my duct work due to rodent damage. They came right out and finished the job quickly and efficiently. Bill and Trish are great to work with. They are a small mom and pop shop and offer great values as you deal directly with the owners of the company. I highly recommend!

I called Cool Air technologies Sat and talk to the owners wife who explained it’s just her and her husband Bill who have the business. Bill came out with his assistant within an hour and fixed my A/C. He test it and it was low on Freon. He explained that since my A/C was an older model that it needed R22 Freon which is being outlawed in CA in the new future. The cost was $400.00 for adding 2 pounds of R22 Freon which is the going cost. I would recommend Bill and his wife’s company Cool Air Technologies because they give you a fair price and don’t try to upsell you anything. They came out that same day and it was a labor day weekend when all the other companies couldn’t come out for a week.

I surveyed multiple local HVAC installers across several different brands; Cool Air Technologies beat them all out. What stood out firstly was their responsiveness and patience in working with me and addressing my needs. This was a project that was completed in early August when many other operations had more than enough business and little bandwidth to take me on. I had an HVAC system that was >30 years old and needed a complete replacement. Bill and team helped build my knowledge base around HVAC systems and helped me to make an informed decision about what I wanted to do. For reference, Cool Air Tech works with Tempstar which is an ICP brand (think Heil, Day & Night, etc.). After doing research around different brands, I decided to go with ICP for their reputation as being affordable and reliable (essentially getting Carrier quality for an affordable price). Given how much time I spent on researching, I was very particular about the details of the install and really, updating the layout of the HVAC system in my house. Cool Air Technologies worked together with me to meet my goals. I strongly recommend them for their professionalism, Bill’s knowledge and friendliness, and their dedication to seeing the job through to absolute completion.

When Mr. McIntosh came to my house with a big smile, he fixed my air conditioning service and I was expecting a big bill but actually was the half the price as what I had normally paid for my service and so I was very happy with that so he told me that I didn’t need a new air conditioning service. So, if you want A plus service with a smile, half the price, I think, this is the place to call. Cool Air Technologies

A couple of years had gone by and I needed to get it tuned up and I was worried because I didn’t know who to go to and I checked around for a couple of references, and I got a really good reference, and for Cool Air Technologies.

So, I called and it was great. Right away, they were just so friendly on the phone, super friendly. I just liked the feel of this company already, and so they were able to schedule an appointment really quickly. And it was very convenient, they set it up for a time… more… less
