This is what Aisen sent me after refusing to share with me all the details of the $9500 jobs, so I had to get another quote which was a better value. I paid him $50 because we had not agree to a free quote. He waited for the $50 to be transferred before he sent me this: “So you always use to do the dirty stuff and give opportunity others to do repairs and installs. All due to respect, don’t ever call me again” Stay away!

I highly recommend High Side as they were able to provide crucial information regarding our old heater when another company failed to do so. I would happily use them again.

Answer quickly and is knowledgeable on appliances. Has the appropriate tools to troubleshoot appliances and is always on time.

Contacted High Side HVAC for a job changing my thermostats to Google nest thermostats and their rep was super professional and honest. He let me know that due to the wiring what we needed wasn’t going to be possible and that we needed to get an electrician in. He did not charge since he didn’t complete the service and put everything back the way he found it. I will be keeping their information in case we are ever in need of their services

Great repair will be using him for all future repairs. I'm an Construction inspector and you would be surprise how many corrupt HVAC companies are out there this guy is legit. ***** five starts for sure. Highly recommend his repairs.

Our AC went out during a heatwave. We called a bunch of places who didn’t have availability for days. Aisen came within 30 minutes of me reaching out on a Saturday morning and fixed our AC nightmare in about an hour. He’s very professional, knowledgeable, and we felt like we were in good hands. Thanks Aisen!

Great experience from start to finish. The tech quickly diagnosed the issue, replaced the capacitor and contactor with quality parts, and had the system running cold again in no time. Professional, honest, and didn’t push unnecessary repairs. Highly recommend this company for HVAC service.

Aisen called me within a very reasonable time and luckily, had some availability before another appointment so he came over, reviewed everything going on, suggested some solutions/options with no pressure tactics. Straight forward and even talked about the issue on the phone prior to arriving so he could get straight to the point on the visit. I’ll look to use him in the future due to his professionalism and no pressure tactics.

They did a great job at finding out what the problem was I thought it was a capacitor and he found out. It was the connector. It could’ve been both, but we had both installed within an hour and came back the next day and it’s been working perfectly ever since very nice very trustworthy and kind.
