Amir and his team were amazing. I have an old central AC unit and every room was a different temperature. There was a 20 degree difference, so to keep cool we would use a ton of electricity. I'd been putting off getting someone out to repair it since I figured they'd say we needed to replace the whole system and it would be too expensive for me. Finally the heat and the bills were unbearable and I found Amir on Thumbtack. He came out and evaluated the issue, quoted a very reasonable price, came back on the day promised and fixed the issues - thermostat was in the wrong place and there weren't enough return ducts. The job was more difficult than expected (attic access to one of the rooms was blocked) and he had to spend a few more hours to do extra work. But he kept his price as originally promised. The work was excellent and now every room is the same cool temperature and I can see on my Ecobee that the energy use has already dropped. I've been asking myself, why I waited so long to do this. I highly recommend Amir HVAC.
