Customer Reviews

Sharon Oshiro

We had our system cleaned and service technician was very neat and cautious regarding the area. He lined the carpets with tarp, and cleaned every aspect of the air conditioner and unit outside the house. He did not rush but meticulously took his time to insure all was done properly. When done, he cleaned the area he was working in to make sure there were no residue of any sort. We were extremely pleased with the work done!

Kevin, Kristi, and the entire team at Air Source are awesome and have been so great to work with. Worked with them over a few years in replacing existing split AC units and eventually adding them to all the rooms in our home. They provide excellent communications and recommendations on the proper units for each of the rooms. The teams are well trained, very flexible in working with us, and work with a friendly and positive attitudes. It felt like I was working with friends in our community. They also helped in getting good prices on current first class products, and in obtaining available price credits. Overall the products and services they provide are an exceptional value.

Air Source Air Conditioning are a reliable company and always are friendly, when they come out to service my other units. The service techs did a nice job replacing and installing a new A/C Unit this past summer of 2025. I was given a rebate that helped bring the cost down. I really appreciated that! Thank you, Kristy! Thank you ASAC! ??

Staff and techs awesome, however I am greatly disappointed with the quality of the metal of Mitsubishi, its showed rust after just 2 years, I have a Fujitsu 9 years old on same side of house, still no rust at all. Even the screws on the Mitsubishi are rusted, so they aren’t stainless steel

Very positive experience. Quick response and excellent communication. I had a Mitsubishi unit that was installed by Alternate Energy that was not working properly. They said they would not be able to come and inspect the units because they were too busy installing new units, but could come in about 2 months. They had previously installed three other Mitsubishi units for me. This is how they rewarded me for my loyalty. Air Source called me the next day. Kristi and Kevin at Air Source came down to see me and were able to install a unit within a short period of time and I was able to have family over for an upcoming celebration. They really saved me when I really needed help during the hot summer month. They are now and forever my AC service provider.
