Get matched with top tankless water heater repair pros in Herculaneum, MO

"Remove electric water heater and install a new high efficiency gas water heater."

"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"I hired this company to extend the natural gas in my house and would definitely recommend them. I felt that the plumber who did the installation really knew what he was doing and seemed like a great guy. The installation went well and the price was fair."

"Mayo plumbing is amazing! We called John for a leak from our main water line in our basement. He rearranged his schedule to fit us in & didn’t leave until the job was done. He was able to fix the leak with a less invasive method than what another plumbing company we had already contacted quoted us. Many thanks to John! If we ever need plumbing work again, he will be our only call!"

"The boiler was fairly new, but had never been serviced. The workman came on Saturday in response to an emergency call, and fixed the boiler as well as performed basic maintenance which badly needed to be done. He didn't bleed the radiators, so I will be contacting the company to make arrangements to have that techs do this as well. I would consider relying on Vitt's for routine maintenance of our heating system, as well as replacement of our water heater."

"I had to shut off the water to my house so I needed fast service. Within about a two hour time frame they arrived, took care of my issue and I was able to turn my water back on!"

"Froggy's called me immediately after I submitted my request on Angi. We discussed the problem I was having, and they gave me several ideas to try to get my A/C unit running properly before actually coming to take a look. I ended up taking their suggestions - cleaning the unit and blowing out the drain line - which resolved the issue. I appreciate and respect a company willing to provide a few troubleshooting/DIY tips before being eager to charge a service fee. Will definitely call in the event I need help in the future."

"I ORIGINALLY HIRED THEM TO REFINISH MY BATHROOM. IN THE PROCESS, MY WATER HEATER BROKE. THEY REPLACED IT THE NEXT DAY AND WERE VERY PROMPT. THEIR PRICES WERE COMPARABLE TO LARGER CHAIN RETAILERS. I WAS IMPRESSED!"

"The service technician was friendly and professional. He discovered the problem and repaired it quickly. The price was reasonable and the problem has not returned. I would definitely recommend this company."

"I had never used Home Advisors. What a wonderful surprise! I had to replace my water heater and had gotten a previous bid from another contractor. Not sure what happen but I'm very pleased with the knowledge, timeliness and profession job the installers & the office manager demonstrated. I will recommend JT Dunn to my family, friends & co-workers. I'll use them again should the situation arise."
