“The repair person was very thorough. During his inspection, he noticed problems which were overlooked by other companies and he also completely cleaned the A/C compressor. I am entirely impressed with his attention to detail and will use his services again.”

“Caspian Air is a 5 star company. I really appreciate the professionalism in their work. Alex came through for us with a great A/C replacement of my old worn out unit. Couldn't be more satisfied with the install and service. Highly recommend Caspian Air.”

“Clean and professional install, and easy to work with. Will for sure be using them again.”

“Called Caspian Air HVAC when the original installer of our 1 year old heat pump HVAC system was unable (after 3 attempts) to figure out why AC was not cold. It took Alex all of about 1 hour to find the problem the other guys couldn't. He ordered the part, came back to install it and had our system up and running the same day. Very happy to deal with such a competent, knowledgeable professional — and a nice guy too. Highly recommend.”

“Caspian Air was very professional, upfront and honest about pricing, quick and very clean work. Would recommend to my friends and family.”

“Alex fixed our ductless AC units in the middle of summer quickly and professionally. Before Alex we had other companies give us extremely high quotes without fixing anything. Alex came, inspected and tested it, immediately told us what was the problem, did the repair at a lower price than everyone else was quoting. He knew exactly what he was doing — honest, professional and quick to resolve the issue. Would not use anyone else!”

“Very nice crew and he does an amazing job. If you are looking to support a small business that is family owned I would suggest this company.”

“I was getting so frustrated because my thermostat seemed to have a mind of its own. The AC wasn't cooling properly, and the temperature in my house kept changing even though I had everything set correctly. After trying to reset it myself and getting no where, I decided to call Caspian Air. Alex came out right on time and was incredibly professional and kind. He took the time to check the system, and kindly answered all of my questions. I never felt rushed or pressured into unnecessary repairs, which I really appreciated! The problem was fixed that same visit, and my AC has been working perfectly ever since. It's such a relief to have my home comfortable again. Alex was honest, knowledgeable, and genuinely cared about doing the job right. I would absolutely recommend Caspian Air to anyone needing HVAC service !”

“I contacted Caspian Air as I was having issues w my new Nest thermostat and my HVAC system wasn't working the way it should. Alex came out, took the time to carefully check everything. He inspected the system, checked the connections, and figured out what was actually causing the problem. I really appreciated how patient and professional he was throughout the process. The repair was done efficiently, and he got my Nest thermostat working properly, and he made sure everything was tested before leaving. He also kept my home clean, which I really appreciated! It's rare to find someone whose not only knowledgeable but also genuinely cares about the quality of their work. Alex clearly takes pride in what he does, and I would definitely recomend Caspian Air to anyone needing reliable and professional service!”
