  I give two stars because Paul, the technician, was respectful and the system works now. In total, I paid around $4,700 to fix my furnace. I chose Yuhan because a neighbor recommended them for being straightforward and transparent. That was only true with the first invoice. The initial diagnosis was $1,800 for parts and $300 for diagnostic labor to replace the blower motor, harness, and drive board. I accepted that. After that, I was told the thermostat needed to be replaced. I agreed under the assumption that the cost would be relatively minor. Then I was later told the main control board also needed replacement. Once all of this was done, I was billed an additional $2,500. My simple Honeywell thermostat was replaced with a Lennox S40 smart thermostat. The new main control board they installed is a communicating control board, which requires the S40 thermostat to work. The issue is not the technical approach itself, but that I was never informed that switching to a communicating board would force the use of a much more expensive thermostat. I was not given the choice to stay in the standard 24V configuration, which is the mode my furnace was previously operating in. When I requested an itemized breakdown of the parts and labor to understand how the additional $2,500 was calculated, the manager stated that it is the company’s policy not to provide itemized pricing. The explanation given was that my furnace “can only use smart thermostats,” but the manufacturer’s documentation shows that is only true when the system is configured in communicating mode. My system was working with a standard Honeywell thermostat before this, meaning the communicating conversion was not required for the repair. After “explaining” why the Lennox smart thermostat was used, the manager immediately shifted to asking whether I was going to pay the invoice “now.” At that point, I was simply trying to understand the charges, and I did not even have a working payment link. The interaction came across as pressure rather than support, especially after the cost changed significantly. The system runs now, but the lack of transparency and the absence of clear cost discussions made the experience frustrating. I believe homeowners should be given options and pricing details before changes are made that materially affect cost.

  We hadn’t had heat for five days and the cold was coming. Paul was terrific and respectful of our home. Covered his shoes and after a short history went right to work. He had the unit up and running in no time. He knows his stuff - Great service. Thank you Paul and Yuhan for your quick response.

  He did not find the real issue with our HVAC system (spending 2hrs) and still charged me $245 for cleaning the ignitor, plus the service charge of $100. I do Not recommend.

  We had a very positive experience with Yuhan (installing our new HVAC system) from start to finish. Our home is built in 1923, so it required a creative approach while still maintaining the integrity of the space. Jose is extremely professional, excellent communicator, and was able to convey our options clearly. Diego and his crew (Juan and Joel) worked very fluidly and efficiently through the installation process. We appreciated the consistent check-ins and Jose made sure we had updated progress reports throughout installation. They took care of the space and were very thorough in their work and the clean up. Yuhan was recommended to us by our neighbors, and we wholeheartedly recommend them. If you are looking for installing HVAC they will treat it with care and expertise!
