"Absolutely fantastic!!! Locating someone who is honest and competent is difficult to find in HVAC - if I took the word of every tech that said "you have a cracked heat exchange", who scared tenants into believing that they were dying from poisonous gases, I would be out $35k in under 2 yrs. (One of those claims was not a cracked exchange but a wasp's nest.) I found Mike's name on Angie's List after I took over managing our family's residential and commercial properties, and after being lied to or being mislead by incompetent techs. Other than familiarity with HVAC as a homeowner, my experience was limited. Mike helped me navigate through my "on the job" exposure, beginning with identifying for me the unique/odd/old units in some of our apartment buildings that some techs had never seen before. Mike was the 4th company in a row that I called who didn't work on that type of unit. But he was the first that didn't charge me a service call, and the only one who could identify the type of unit it was and who could work on them. Since that time, Mike has been my most prized contact! He arrives on time, is respectful to our tenants and their homes, and he has never walked away from a job because he could make more money on another service call - we had another valued HVAC contact who went MIA, stringing me along, while a post-op tenant was enduring week long heat wave. When I called Mike, he was out the next day, and had it fixed in three hours. It was a tedious job, but he did it. As long as I am responsible for our buildings, he will be first on our call list!! I believe in honor and loyalty, and this company deserves mine!!!!!"

"Mr. Ferrell worked with my husband over the phone to fix the problem. It was surprisingly fast and stress-free. To have the work done remotely in less than an hour was wonderful."

"When the unit stopped working, I call several Madison area companies to get estimates. Harker was one of just 2 that responded quickly to schedule a visit and give me quotes. Harker was competitive, and it was replaced the next week in a day. The technician, Eric, was excellent and thorough. Unit functioning great."

"Great job. Prompt and good service"

"Marco from R & G did an excellent job replacing the water heater at my rental property. I have called him many times for a variety of services at different locations. He is very professional, and I recommend him to anyone looking for HVAC services."

"Great! Dillon was efficient, very pleasant and answered all my questions. I would definitely hire them again and recommend them to your customers!"

"Installed a new AC unit. Great price, efficient work, and very courteous. I would hire them again for the same service or for yearly maintenance."

"The young lady that I spoke to (twice) was very pleasant. I TOLD her it was a very small job and if they were too busy, perhaps they could recommend a handy man or someone who specializes in "little" jobs. She assured me that someone would come out and take a look. NEVER happened, no phone call. Very disappointing."
