Gas Furnace Repair in Wolverine Lake, MI 48390

“Today I had Technical Hot And Cold come over to get my 2014 Lennox furnace working. It took four days to get an appt. The burners wouldn’t stay lit so I had no heat. The technician did very little other than spend about 20 to 25 minutes in his van talking to somebody, then he came in and told me I needed a new heat exchanger because his carbon monoxide detector indicated that my furnace was producing more than 2000 ppm and it should only be producing 1 ppm! My son talked to him and the tech said he couldn’t tell if the heat exchanger was cracked or not because it was too complicated to see inside it. He said he could tell it was cracked because the flames shot out toward him when he turned the furnace on. He said the burners would all go off because it tripped the sensor that protected the furnace from burning the place down. My son asked if he had checked for blockages in the vents and he said no that you couldn’t get inside them to check. He did not go on the roof and take the cap off the vent pipe. In the text said it would cost over $2000 just for the labor to put in a new heat exchanger. And it would have to be ordered so I would have no heat until the end of next week. Thank goodness my son had me call Harriman!! Damon came out within 2 hours and immediately diagnosed the problem and fixed it for $200!!! He cleaned the outtake pipes with bleach and took the burners out and blew them clean. He even replaced a wire that looked suspicious. Then he showed me his CO meter registering 1 ppm. He offered to talk to my son and was absolutely wonderful and patient thru the whole process. I told him I will always ask for him in the future. What a treasure it is to find an honest company and a truly professional technician!!!!”

“You were recommended to us by Trane Company after another company tried to scam us into purchasing a new furnace. Mitch came out and took a look, was very pleasant and knowledgeable, and let us know that a new furnace was not needed at all, in fact, there was nothing wrong with ours. He spent a lot of time with us to make sure there was nothing going on with our furnace and explained everything in great detail. We are very appreciative that someone came out to take a look so quickly, and Harriman has become our new Heating & Air Conditioning company to call if needed. If something is needed, we would want Mitch to be the one who is sent out. We truly had a great experience and we are thankful we found a company that we can trust! Thank you all, especially Mitch.”

“The technicians arrived in a timely manner. John G and Junior where very professional and knowledgeable. They answered all my questions and shared a few tips and information that will be useful in the future. They where diligent in their work. They cleaned up and left the furnace and air conditioner, cleaner and working much better than how they found the units. I was impressed with how focused and considerate they where. It is not uncommon to get good service but to be fortunate to get the efficient and dedicated service that John and Junior demonstrated was exceptional. Thank you guys and I will be using you in the future. I will be passing on recommendations to others. Thank you for your hard work and knowledge.”
