Delta Sierra Mechanical

The service tech Henry, replaced my thermostat and reset the system so I could resume controlling my system via the app. He also suggested purchasing the HVAC twice yearly maintenance plan which was money well spent. This was my first time having my system serviced by Delta Sierra Mechanical, and I am EXTREMELY pleased and would HIGHLY recommend them. 1/26/26 I just found out I never posted the above comments regarding Henry. His work was performed in 2025. Today 1/26/26, I had to call Delta Sierra again for a different problem. Thank goodness Delta Sierra is an authorized company that AHS works with. My heater was not turning on and Delta Sierra sent out their tech Adrian. Adrian was FANTASTIC, and because of the POSITIVE, Professionslism from Adrian, I wasn’t surprised. Adrian found the problem and upon futther review, Adrian was very proactive in addressing another potential problem that could cause further damage. I even went so far to call Delta Sierra and asked Janet to relay my EXTREMELY Satisfied feelings to the office manager or the owner of the company. I am a VERY SATISFIED customer of Delta Sierra and would hope they would answer the next call if I needed service. Delta Sierra trains their techs the right way AND it shows. Steve Sale 1/26/26

I had another great experience with Chris Buethe from Delta Sierra Mechanical! This is the second time Chris has serviced my HVAC system. Last year, he came out to replace a capacitor, and this year he provided excellent service again. Chris is always polite, friendly, and professional. He takes the time to explain what’s going on with my HVAC system and educates me about how everything works. I truly appreciate that he doesn’t just fix the issue, he provides solutions and makes sure I understand how to prevent future problems. It’s reassuring to work with someone so knowledgeable and trustworthy. I highly recommend Chris and Delta Sierra Mechanical for HVAC service!
