This company was absolutely fantastic! After dealing with a very frustrating experience with my…read morehome warranty company, I was without a furnace for about a 1.5 months. Hubbs was selected as my second contractor to diagnose my repair needs and make recommendations. "Misty" at Hubbs was wonderful and very good at keeping me informed every step of the way and letting me know the status of my order with my home warranty company. She was very professional and understanding of my frustration. Their arrival was always as scheduled. Their installers were very professional, personable, and mindful of not damaging walls and flooring during the replacement of my entire furnace. My house is finally WARM after a relatively quick installation and cleanup. Thank you Hubbs for your excellent service. I have already recommended you to family and friends for their heating and cooling needs. Best wishes to the Hubbs family for 2018! R.

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. I dropped my contract and have been with KNOW ever since - you WILL NOT find a better HVAC company with amazing customer service and integrity. Ask for Scott! I have referred 5 people since then and they all love the service.

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.

Never hesitate to get a second opinion. I understand not everyone's skill levels are equivalent but…read morein the course of 3 months and several repeat visits and upwards of $1500 paid out to this contractor the true problem was never addressed. 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.
