"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"Sev was a total gentleman & didn’t mind letting me know the problems he was having while diagnosing the overall situation, which is very important to me. He also put up with my tiny rugrat as he lay on the floor to get to wires & she fighting to get to his ankles for a good cleaning! Thank goodness the owner was there to intervene! Really, though, Sev went out of his way to make sure I had AC today & not a moment later! He even threw in a much needed extra in order to make sure my ac was cooling at top speed! I’m grateful & my tears of relief are real. I don’t do well in the heat & my landlord is not really able to help me with this issue now. I can finally rest well tonight! Thank you, Sev & southland heating & AC! I truly appreciate it! And, also, much gratitude for Angie’s List for making it so much easier to find trustworthy repair companies!"

"Serviced my AC was very friendly and informative. They gave me tips on how to make my AC run better and last longer."

"I’m so glad I called HD mechanical to have my thermostat fixed. We set a time to meet up and he was there on time and very professional. He was very thorough with his work and explained to me all the work he performed. He even checked and serviced my unit, showing me that my filter needed to be changed. Would definitely recommend to anyone who needs and service/repairs done."

"He was thorough, knowledgeful, listened to my concerns, respectful and got the job done quickly and efficiently with my plumbing problem. I would recommend Alpine Heating, plumbing and electrical services to anyone...and do recommend them."

"I needed my HVAC system urgently repaired, the technician arrived promptly to resolved the issue. They were professional and knowledgeable and gave me honest recommendations & also was very helpful. Highly recommend! Thank you!"

"On the hottest day of the year in Los Angeles,  I called because my a/c would not come on.  Luckily they were nearby and offered to come right over .   They diagnosed the problem as a dead transformer,  had a replacement in their truck,  fixed everything and had it running in an hour.  this was my secon use of them and in the winter when I had heating problems, they were as quick and more than fair and honest.  Every service company should model themselves after this company."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"The service went great. One technician came out and completed the job in about 30 minutes to an hour. The vents had not been cleaned in about 20 years and really needed it.  They were very direct and did what I needed. I had no problem scheduling the deal."

"Excellent customer service and fast! I highly recommend them, if you need a new system or maintenance this is the company to call!!!!"
