Consumers be aware that they only service the 37909 area code. I found their website with a free pool inspection coupon, so I called the number. I gave the zip code and was told I might be outside their service area. I mentioned the coupon on their site and was asked to confirm where on the site it was then was told they recently updated their service area to only 37909 but their website says they service Knoxville and surrounding areas. Their website is truly misleading. read more

The call to set up an appointment was fine and the tech arrived on schedule. He did some diagnostics and said we had a refrigerant leak in our mini split and would need to replace the unit. He was fair in stating he was at the 30 minute threshold and didn't recommend we keep him any longer or pay for more time which was nice. Received two quotes to replace the unit at 4-5 thousand dollars. Called someone else out and they spent an hour diagnosing and repairing for the same amount as the JH Coleman diagnostic visit. read more

Had Coleman Care for about a year. At first it was a deal, considering the filters came with the twice yearly visit. The techs are nice, but they've told me they may discontinue providing filters which is most of the benefit. Recently they misdiagnosed something that should've been rather easy to figure out and charged a $270 diagnostic fee (that was with Coleman Care discount) and then quoted almost $1,300 to fix it, requiring some expensive parts replacement. I called a second company for another opinion. They correctly diagnosed it and fixed the whole problem for $150. I think all of their services are higher priced than competitors, even with their supposed Coleman Care discount. Cancelled Coleman Care and will use other providers. read more

John H Coleman has the very best customer service. On a day that could be considered the worst, they made it better. They have always been responsive and communicative, you always know when they will be there. They never have a 6 hour window. Their service staff are friendly, knowledgeable and helpful. I will always recommend them. read more

Our Experience has been nothing but disastrous. We had a $14,000 unit installed, back in the end of October 2023. Since then we have had then out to preform at least 6 repairs as the unit continually ceases to keep up with the warmer temperatures even back in a few warm days in March. They made some changes that seemed to work and for a month it seemed finally resolved. In May we one day look up and see a massive stain on our 2nd floor ceiling. Called them up, and it turns out the installers left a port open and did not level the drain pan and it allowed water to flow out all over our ceiling. They fixed this and sent a company to repair the ceiling. Then most recently at the end of June, we return from vacation and the area is at 89 degrees and the unit is again not running. Since then we have been having to almost daily reset the breakers and we are to the point that it on a good day only can keep the area below the low 80s. We are still working with them to resolve but we will never ever use this company again. read more

I may have to change my mind on my rating after this next visit. Right now I'm down to 3 Stars based on the 20% price increase and the only discount available if you sign up for automatic rebuilding. Sorry they went from $189 to $238 with the automatic rebuilding and $275 without out it, and when they didn't have the automatic rebuilding they'd email and send bills multiple multiple times and with the automatic rebuilding they sent no notice my credit card was being charged. read more

I had them out on a service call and a employee his name was don, he was a arrogant jerk. His attitude is non professional and he needs to appreciate the customer. I will never call this company again! read more

The service technicians are always on time as promised. All our questions were answered, and if it was something the service person wasn't an "expert" on, he had another employee contact us within a day. John H. Coleman always notifies us in advance when we're due for service, so I don't have to constantly refer to our calendar - one less thing I have to worry about. Staff are always clean, friendly, and professional. read more

I switched to John H Coleman for my semiannual service check ups because the former company was always trying to up-sell services...at every visit a 'sales manager' would show up with the technician. My last Coleman visit they started the same schtick. I'll decide on their next visit whether this becomes their norm, if so I will change companies again. read more

Signed up for a Coleman maintenance contract last year. They came out for the Fall service in November but didn't bring air filters. No one contacted me for the Spring AC service. I had to call them in June and they gave me an end of July date for the AC service. I thought the service was supposed to be at the beginning of the cooling season! Then they were more interested in upselling, offering sewage line inspections and electrical inspections. Are you kidding me? Does your electrical system just go bad all of a sudden? I had an issue with my upstairs heat pump a month later in August. The blower fan was not blowing and the coil on the upstairs unit was frozen. They sent a tech out 2 days later who diagnosed the problem as either a bad blower fan or a bad control board (total cost to fix $1400). I mean a blower fan costs $200-300 plus labor and a control board is maybe $100-200. I had someone else come out who found a leak in the coil. The unit was losing coolant so it would freeze up and the blower fan could not move air through the frozen coil. So if I had done what Coleman had recommended I would be out $1400 and would still have had to replace the coil. There are better companies out there. read more

Even though I had just been laid off from my job, I pulled everything I had to buy a new heat and air unit so at least my family could be comfortable. It took longer than expected to get the unit but they told me it was due to shortages associated with the pandemic so that didn't really bother me. What I'm upset about is that after about a month or so, the unit has frozen up and our house temperature has ranged between 75 - 80 degrees downstairs and much worse upstairs! They've come out several times to "fix" it but as of 1:30 this morning, we had to sleep down stairs because it was unbearable in our bedrooms. I called the after hours line today (closed for holiday) and was told someone from installation is planning to come to our house tomorrow to go over the unit from top to bottom which is great but when we're they going to tell me? I had several other things planned for the same day and would probably have missed them! I asked him to at least make it for later in the day and I would juggle appointments as I really need the air fixed. So, to recap-poor communication + faulty unit = equals one really unhappy customer! I hope they give me reason to change this review but for now I'm out all my savings and can only wonder if we'll be cold for the winter! read more

Called to set up an appointment for my business for hvac services. Lady that answered the phone started the conversation immediately saying "we will need X and X and X info before we do anything to make sure we get paid" What kind of customer service is this? This is the first time calling this company and they're already acting like we screwed them over before. Dont waste your time here. read more

I am so happy that I chose John H. Coleman to remedy all of the many problems I had with existing furnace. All of their representatives were professional, courteous, prompt and knowledgeable. They seemed to really care about my needs and preferences and they went "above and beyond" to take care of me. read more
