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. Our regular HVAC tech confirmed that it was a simple fix and the furnace has plenty of years of life in it as it's only an 8 year old unit.

However, I…read morefeel I need to share my story with anyone thinking of calling this company for their furnace needs. We bought a house back in 2012 and were given a home warranty that would last one year. We've renewed this warranty every year and up until last year they would always send out All-Knight when our furnace would act up. Our furnace would act up about every four months. It wouldn't blow out any hot air, it would try to kick on but just couldn't. We would call the home warranty folks, they would send out All-Knight. The tech would go in the basement, hang out for maybe ten minutes and say it was all fixed! It was just a dirty heat sensor. And the furnace would work again.....for about four months. We dealt with All-Knight so often that we were on a first name basis with the receptionist, Brenda. We almost invited her over for Thanksgiving!! After YEARS of dealing with this, our home warranty company finally switched to a different HVAC company. Last fall the furnace wouldn't work as usual, we called like we always did. However, this time they sent out an unfamiliar face, a gentleman who was not from All-Knight. He took one look at our furnace and asked "Who has been messing with this furnace???" As soon as I said All-Knight he recognized the name and said I am not the first customer to throw out that name when having constant furnace issues. I told him that it should only take him a second to fix because it's always the heat sensor according to All-Knight, and he just shook his head. He worked on it for about 30 minutes and it has never broken since. It's been over a year!! I think the evidence is pretty clear that the home warranty company as well as us, were scammed all those years. I would avoid these guys at all costs!! Or your cost may be way higher than you could ever dream of!!

The owner came out the next day to speak about a replacement unit for the furnace. No pressure but many options. We also discussed a new AC since they were the same age. A week later new units were installed. They were experiencing some issues with pictures and communications, but kept in constant contact. The 2 techs who worked on the installation were so professional. They asked about music playing and using a bathroom. They insisted on wearing booties over their shoes even though I was not concerned in the least. It was like they were working in their own home to be honest. I don't know where they may rank on price, but my experience was well with it. We pay for quality even if not the cheapest. I look forward to renewing my annual service contract.

The big name company with fancy commercials on TV And took monthly service amounts to "make it easier" for me. 2 years ago they said that I needed to replace my ENTIRE air conditioning unit that they had been servicing for almost 10 years. The unit was only 11 years old at that point. They tried to sell me a new one for $9k !!!! I decided to get a second opinion and had 3 different companies come to check the unit. THERE WAS NOTHING WRONG. They said someone had loosen up a valve and all the antifreeze was gone. Needless to say I was almost the victim of fraudulent business practices.
