Now, De Hart Plumbing Heating & Cooling is recognized as the leading company in Manhattan and Junction City.

Recommended Customer Reviews

Our ac wasn't working. Went thru insurance and was able to have expedited service due to holiday weekend. Lawrence was Very professional in his advice to me. Shortly there after Anthony and Thomas arrived. These guys were top notch professional, friendly and had zero problem explaining things to me. Thank you again for helping with our issue!

There had been a stinky sewer smell in my office building for literally years. Two other plumbers tried to find the source of the smell and could not. DeHart suggested a smoke test which would show if there was a leak somewhere in the system. No one else ever suggested this test as an option. Sure enough the smoke test led us to the leak which was due to an improperly sized cap. New cap installed and the awful stink is finally gone. DeHart is my hero!!!

They blew up my compressor and had to call them over to weeks later for awnsers and got an attitude from the receptionist for asking simple questions. No apologies for the damages they caused only a 5200 hundred dollar estimate to replace the entire system.

We had our pipes back up when we first moved into our house and DeHart plumbing came out and unclogged them and also showed us a few ways to troubleshoot if it happened again. Very friendly and professional staff! Highly recommend

My husband is active duty military and in the midst of pcsing and trying to move to Las Vegas our water heater broke. Dehart is a wonderful company! They came out on short notice and installed our water heater right away so we were able to sell our house! This was in July of 2017 and I still recommend this company to anyone I still know in Manhattan Ks! 10/10 would recommend this company for all of your HVAC and plumbing needs! The owner and technicians are knowledgeable and offer great customer service! They also have fair competitive pricing! Need a plumber? Use these guys!!

I live 21 miles from their office address and called to get a complete HVAC estimate. I was told they would not provide an estimate due to distance despite their advertising saying they service Manhattan, Junction City, and surrounding areas. I was happy to hear that other HVAC companies were more then willing to come to my house and provide an estimate.

My house is old, with as much character as it has maintenance needs. In the last month my hot water heater, a shower faucet, and an end cap on a cast iron line under the stool all went belly up. De Hart took care of it all - efficiently and professionally. Their staff was awesome. LeAnn, Kurtis, both Chris's and Zach, earned a 5+ with me.
I've been fortunate enough to receive good customer service with various home repair companies. But these folks are in a different class. They were extremely professional, while also friendly, informative, and skilled at diagnosing and fixing the problems quickly. I signed up for the VIP furnace and AC maintenance plan without batting an eye. I know it'll pay for itself in the long run by extending the life of my ""mature"" HVAC system. Their furnace maintenance was thorough, and the receipt included a detailed rundown of system pressures they took. They explained that these readings will be used as a baseline for comparison next year.
They informed me about basic maintenance I can do. I'm curious about this stuff and like to learn, so I can do as much of it myself as possible.They even put easy instructions for annual water heater draining right on the unit. I have confidence in their integrity, that they will only suggest maintenance or repairs that are actually needed.
Also, Leann went to bat for me when I ran into a snaffoo with my home warranty company, when they ordered the new water heater from Texas rather than getting one locally. Leann made extra calls to iron things out, got authorization to order a unit locally, and we had hot water pronto.
Lawrence, thanks for your commitment to excellent service. This level of quality starts at the top. And thanks to your awesome staff for taking such pride in their work, and good care of me and my old house.
Oh, and I'll add that my review is as true as my wish NOT to have anything break today. I really like all you De Hart guys and gals, but I'd rather see you in the grocery store:-)

This will be the only plumbing/HVAC company that I will use from now on. They have come to my rescue several times and each time the receptionist has given me quotes the were spot on. Every tech that has been to my home has been very courteous, professional, knowledgeable, and proficient. I highly recommend this company.

I have noticed considerable savings in my heat and cooling bills since my system has been installed. Lawrence answered any questions I had well after the job was completed. Since then I've called them back for my shower plumbing and will continue to call them as needed for plumbing needs.

As a new homeowner, I called Dehart because they had cleaned and serviced my furnace prior to myself purchasing the home in August. I needed to know where the furnace filter was located and how to program the thermostat. Well, just showing me those two items in 10 minutes I was charged $103.50. I was quoted $40.00 on the phone to do the service. Oh I was also told if diagnostic had to be done it would be more. The technician saw my veterans plate and gave me a 10% discount, the price above includes a 10% discount.
They could of gained a good customer for future business but instead I WILL NEVER DO BUSINESS AGAIN WITH THEM!
