My experience working with Cham from SuperTec to install a thermostat:…read more A friend had previously installed a Honeywell thermostat for me and it worked perfectly for 1.5 months before a fuse blew. My apartment maintenance reinstalled the original Emerson thermostat, and decided to hire a professional to complete the install. First tech visit: Before Cham installed my thermostat, my A/C was working perfectly with the original thermostat - blowing cold/warm air with no issues. After he installed the Honeywell thermostat, the heat worked but the A/C was NOT working. It was blowing warm air instead of cold. I checked and told him the A/C wasn't blowing cold air. He told me to "wait it out" and "take his word for it" that it would eventually come on. I had to leave for work, so I paid his invoice and just trusted him. When I got home at 9 PM, I set the A/C to 60F when the room was 73F. After running for an entire hour, the temperature stayed at 73F. I texted him at 10 PM to report the A/C wasn't working. Second tech visit: He came back and claimed the problem was low refrigerant levels. He took refrigerant readings with the Honeywell thermostat installed when it was 30F outside. He himself stated that refrigerant levels should only be measured when outdoor temperature is at or above 65F. Yet he took readings at 30F. At my request (maintenance required the original thermostat to be reinstalled for work orders), he said reinstalling the original Emerson would cost $100. I agreed to pay because I thought maybe there really was a refrigerant issue. I paid the $100 (now $250 total invested). He reinstalled the original thermostat and immediately the A/C started blowing cold air. I told him it was now blowing cold air. He claimed it didn't appear to be blowing cold air despite me feeling it clearly blowing cold. He had taken another refrigerant reading with the original thermostat at 33F outside and claimed both readings were "almost identical." The the A/C worked perfectly with the original thermostat and didn't work with his Honeywell installation. If refrigerant was truly the issue, the A/C wouldn't have worked with either thermostat. He then suggested I return my Honeywell and buy a new one to prove the thermostat was defective (not his installation). It was past the return window, so I would've had to buy another $90 thermostat. He said if the new one worked, it would prove the first thermostat was bad. If it still didn't work, he wouldn't charge me again. At this point, I had paid $250 and saw his story wasn't adding up so I hired another HVAC professional. Before tech started work, me and the tech tested both heat and A/C together. Everything worked perfectly. The tech installed the exact same Honeywell thermostat that Cham from SuperTec had installed (the one where A/C wasn't working), and now BOTH heat and A/C work flawlessly.

He then suggested either a complete rewiring or a new unit (trying to force us into a new unit as he claimed rewiring parts wouldn't be able to be sourced.

On top of that, he also said we needed a new TXV, except it turned out that was also incorrect. The TXV was, and still is, fine. It was later discovered by a different company that on the original visit the co-worker had badly overcharged our unit to the point where the excess refrigerant had to be bled off and recaptured before it caused bigger issues, like mimicking a bad TXV. We used the different company for that, they didn't charge us for it, and I won't bother calling Air Supply ever again. I used Air Supply based on recommendations here on Yelp and from several neighbors. Not sure why we got so lucky but we ended up spending a LOT of unnecessary money chasing down "a very obvious issue" and having someone else fix it.
