"Zack and the other technician who installed my AC and heating unit were very professional. They arrived on time and put on booties to cover their shoes before coming into my house. Zack verified the system I was having installed. They laid down traps on the stairs and down the hall. After they had completed the installation, he showed me the new unit and explained what they have installed. Zack explained the new thermostats installed and they cleaned up before leaving. They did an awesome job. The entire experience with Cool Ray starting with the initial technician visit, by Cameron Long, the Comfort Consultant, Esli Lara and the installation by Zack was amazing."

"Very well. I was having the biannual inspection done of a system that Estes installed. I have had good customer service on each occasion and am extremely happy with the system they installed, which was a difficult job (new duct work on an older home as well)."

"CAELUM Heating and A/C did an excellent job installing a replacement electric furnace in our attic to connect to an existing heat pump two floors below. He FOUND that the copper cooling line was ORIGINALLY installed at a 3/4” connection but downsized to 1/2” and caused a huge strain on the system. So he handled replacement of the pipe through the full height of the house to ensure the 3/4” connection was attached to 3/4” pipe. He also shared detailed hvac flow engineering with me to explain what the units should be vented like (size and location) based on the unit(s) installed. Paul is very detailed oriented and he loves his job. -S"

"Trevor has been an amazing contractor who has helped us through the process of installing a large interior door for an office. He has helped ensure the space was properly prepared for installation of the door. The other contractors who have assisted Trevor have also exceeded my expectations. They have been extremely detail oriented and have done everything to ensure the best outcome. I would definitely work with Trevor for any future projects."

"There was very little work to do. They came out on time and I was happy for the professionalism, but there was nothing to do because it's a brand new system. The service is free for a year. I could have had them come out in April to check the air conditioning system, but since they just installed the unit in April, I didn't bother, but it would have been free. This fall, when I called him to check the furnace, he thought he was coming out to check the air conditioning, I said, "no, you're here to check the furnace because I'm going to be using the heat this fall". He said, "no problem" and he checked that out, he said, "I feel like I'm not doing anything, I can still check the air conditioner", and I said, "if you want to, but I've been running it all summer and it's been great". I asked him there was a charge and he said, "no, the first year was free"."
