“If you need service or a full equipment replacement like I got, look no further. You will not be disappointed.
My experience with Harriman Heating & Air Conditioning was by far the best I have ever had with professionals that I’ve had in my home to do work.
Jesse and Jeffrey were faced with a very challenging job and they handled it with professionalism, expertise and impressive knowledge and skills. The job was so challenging that they needed to be at my house for 4 days. Never did I feel concerned that the job would not get done to my satisfaction. They were creative and found a way to get it done, while all the time, ensuring that I was going to be happy with the choices of placement due to a very small space to work in.
Jesse and Jeffrey were so friendly and they were great sports in dealing with my puppy that was nonstop trying to steal anything they sat down for even one second (puppies LOL).
I genuinely recommend giving Harriman a try. I found the experience to be refreshing, since it is so difficult to find good professional service anymore. They were respectful, friendly, thoughtful and most importantly SKILLED.
Thank you Jesse and Jeffrey….You two are the best!!!”

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!!!!”
