$15k on a new HVAC and about 8 visits over several months to get it working. A year later and they are giving me a hard time to come back again when it quit. The guy actually said to me, "we came out 8 times for free" when I said they were a terrible company. So I spent $15k for a non-working furnace and they want to skip out on the warranty and expect me to be thankful they came out 8 times to fix what should have worked the entire time. Now I will have to sue them to get any resolution. Flowtech is horrible. Business owner information Michelle M. Business Owner Feb 11, 2026 Mr. Garmatz. I am sorry you have had a bad experience with us but i feel its important to correct you on a couple points. You made the choice to end the Service Maintenance Agreement with us which did end your extended labor warranty. It does not void your equipment warranty so to say we are skipping out on a warranty is false. We installed your system on 6/14/2024 and do agree there were some issues. We returned 3 times in 2024 with the last time being 9/03/2024 so to say we have been there 8 times is also false. We have not heard from you until last night when you cussed out our service manager for 10 minutes on the phone. We sent a tech, per your demand, found the problem that was unrelated to our initial installation and resolved the issue at no charge to you. You belittled our service manager to the point he had to end the call and told you if you treated our tech the same way he would leave. You said in your first yelp review that if we made an effort to resolve the issues you would update your review. We held up our part of the deal, but you never updated your review. We do make mistakes and have always done our best to correct them and side with the customer. Please feel free to call and discuss this further if you would like. Customer Response Feb 11, 2026 Dear Horrible HVAC Company, I am sorry to hear you are butt-hurt about my calling out your atrocious service and refusing to continue to pay you for failed and incompetent service. Your company returned at least 6 times on my records (yes, I kept that many). I could not care less about your deceptions and lies attempting to make you look better with your well earned 1 star here. If your are deceptively stating that I only contacted once THIS YEAR (it is early February when my $15k HVAC failed yet again due to installer incompetence). I ranted at your staff after they suggested it was somehow nice of your company to come try to fix your incompetence on 8 occasions for free since the HVAC had yet to work properly. I expressed how disappointed I was with their service (damaging my ductwork during an incredibly sloppy installation where they left open wiring and a hole to the outside as well as failure to adjust any settings from factory default among other things). Your company is at best a horrible rip off for anyone using them and at worst dangerously incompetent and deceptive. You wanted to have it out here so why not share it with everyone? Your potential future suckers, er... "customers" deserve to see it. The tech also came and found that the settings were not properly adjusted for heat (seems like you problem to me, but of course you want to shirk responsibility as you have throughout). Since they were here last time during the summer they only adjusted them for AC. At this point, after all the experience with your company I can only wonder if that was not intentional to force another visit. Overcharging, excessive billing, and repeated visits to fix your company's shoddy work seem a frequent report on the internet. I wish I spent more time searching our your terrible record before hiring you at all (Flowtech in Columbia City, IN if you want to avoid them). I filed a complaint with the BBB and am also looking into reporting my experience as a complaint to the Indiana Consumer Protection Agency for HVAC service misrepresentation and failure to honor contracts. But by all means, respond again so I can share my experience with more people again. read more

They took 3 1/2 days at my house to try and fix my AC issue. Instead of just saying hey maybe you should get someone who knows more about this brand of AC they kept trying to troubleshoot it. To no avail. The. On the last day thought maybe he would drain all my refrigerant and charge me 1200$ to replace it. Dont think so. I still ended up paying a total of like 700$ for the 3 1/2 days but they left and never fixed the problem. Everything was the same as when they first walked through my door. What a joke. I use to use them for plumbing and other issues at my old house but I'm done with them after this fiasco. Seems like they're doin anything to make a buck. Would not recommend ever again. read more

They are SOOO grossly over priced, so much that when I complained they reimbursed me a few dollars. Not really sure that their help is very good as it took all day to hook up 5 faucets after we replaced our countertops, 1 in the kitchen and both baths with 2 faucets in each. All the pertinent plumbing was already installed, all they had to do was drop in faucets and connect. read more

Great service. Technicians are very professional and trustworthy and do the most to get the job done the RIGHT way! Will call them every time for any of my heating or plumbing needs read more

I had them replace a handle on an outside faucet, install a faucet I had purchased already and rework an outside faucet that was leaking. They charged me $800. I would had did the work myself but I have lost strength in my hands. They were here 2 hours. read more

Only called them because we had seen their trucks in the neighborhood and I needed to get a simple shutoff valve replaced on a toilet at my daughters house. They responded very quickly and everything went well until they presented the bill for the 15-20 minutes of work. They charged a $79 diagnostic fee , even though I had told them when I called that a leaking valve needed replacing. On top of that they charged $100 for installing a simple valve that costs less than $10 at Lowe's or Menard's. These guys really know how to put it to the retirees and single parents. I will not call them again. read more

Well it was a cold snowy sat morning when the furnace decided to quit. Flow-Tech was the only company I could find that had the part available on a saturday. They knew they could gouge me just because conditions were bad. Price they charged me was 2x's normal cost of the part. The guy tried to justify it by saying he could not separate the cost of labor and material in their system so if I wanted just the part, I had to pay for their labor for me to install the part. He would have wanted another $400 to come out and fix it on a saturday. Can Yelp come up with a grading system that has negative stars, I would use it here. read more

One star is too generous. After being charged for 2 hours at $95 an hour for a quick job that took them 15 minutes, the company is crooked at best. read more

After many times asking for someone to drain my pressure tank, put 25 lbs of pressure in, then refill, I bought a new one due to their insistence, that I needed to do so. The Manager ordered the pressure tank, not seeing my old one which was 81 gal. When the new pressure tank came in he called and quoted me the price $750.00 but didn't say how many gal. Thinking the workman told him the size, I agreed to let them install it. Turns out the pressure tank is a mere 20 gallon, same name brand, which cost $180.00 on the internet. Along with the pressure tank fittings was also installed, at the cost of $109.00. So the total cost for the tank and fittings was $289.00, making Flow Tech $461.00 for the installation. Now if they pay the worker $25.00 an hour, his total time here was close to one hour, Flow Tech made $436.00 profit and I got something worse than I previously had. Reason for replacing was the pump motor ran everytime when you flushed the toilet, got a drink of water, etc. Fearing I would burn up the motor that pumped the water to the tank and the cost would be very expensive, I gave them the job. If they would have agreed to drain my old one, put 25 lbs of air in the old tank, then refill, I really believe i would still have a quality tank. Flow Tech is in business to earn money and not satisfy their customers. A business like this will not prosper. I talked to the Flow Tech manager about this and his answer was, you need to find you another plumber. I talked to the Flow Tech owner and he stated the same. A meeting was scheduled before the owner talked to me. My advice, use at your own risk! (Edited) Sept 30th. I did hire another Plumber. He tells me my old pressure tank does not have a bladder (what Flow Tech told me had burst) and as long as my old pressure tank was not leaking, it didn't need replaced. So what my departed Husband did for so many years, (drain the old one, put 25 pounds of pressure in it, then fill back up) is all they would have needed to do, which is what I told them to do. As I said before use Flow Tech at your own risk. Mary S. Oct 15th 2017. After many weeks since Flow Tech did this job, they hesitantly returned $250.00 of the $750.00 I paid them. I had two options, let them back into my home to install a 40 gal. tank or accept the $250.00 check. Not wanting to admit them to my home again, I chose the latter option. Mary S. read more
