This was simply the best experience I’ve with a repair person! AJ came out, on a Sunday afternoon, and was prompt, helpful, and kind. He diagnosed the issue with my AC unit and gave me options on how to move forward within my budget. He diligently fixed the problem and provided maintenance on the unit. AJ also educated me on how to maintain the unit to save cost. He did not leave until my house was dramatically cooler! This was hands down a wonderful experience. Thanks AJ!

AJ is a true professional HVAC tech. he did a full removal of the old system and installed the new system within a single day. He was very respectful, understanding and provided value to my home. at the end of the day, I chose AJ because of these reason. don't feel hesitant with AJ, he is very good for your HVAC needs.

Credit where credit is due Amarjeet came out on July 8th to service our mini split system which couldn’t handle the heatwave. However while home he spent most of his time criticizing us and the set up of our new homes system. When it came time to payment it was obvious he blindly pulled a number out of thin air rather than actually charging on a base rate or based on the amount of materials used. He also gave payment information for Venmo which I paid immediately. For the next week he messaged me several times saying I had not paid him despite sending screenshot from my bank and Venmo proving otherwise. He then came to my home unannounced banging on the door while I was not home saying we had not paid him.
