I would recommend this company, they were very responsive. Gary was always responsive and explained everything that was going to be done. Assured me that I would get my furnace repair done as soon as possible and Warner delivered. Bradley and Mason came out to do the install and were very professional and efficient. Bradley took the time to explain to me about the system and even made adjustments to my ductwork to assure that all rooms are properly getting air flow for my heating needs. Thanks again

Chris Y. helped me fix my leaking whole-house humidifier the same day. He showed up on time, was very friendly, knowledgeable and professional and took the time to show me the issue and how it could be repaired. Will definitely be using Warner in the future!

Warner was fantastic from start to finish. Tom Welch made sure everything was right from the initial quote, to instal, to receiving a damaged unit off the truck (transit damage) and then immediately working on getting a replacement unit out the very next day. Technicians Thomas and his crew were outstanding. On time, efficient, knowledgeable, and cleaned as they went. If you’re looking for and HVAC or Water Heater don’t hesitate to give Warner a call. Fantastic experience and great employees!

I wish I would have read the reviews before I had Warner come out in May for plumbing issue main pipe to street. 30 days later same issue. They wanted charge $598 which was higher then fist time. If tech would have done it right the first time We wouldn’t need come out again. The customer service is horrible. Superior Josh didn’t care about that tech didn’t give us options needed to fix it the first time and refuse to work with us. He claimed he would call us back and never did. DON’T WASTE YOUR MONEY WITH THIS COMPANY!!!!!!!!

I have been trying to get a $250 rebate since May 2019. It was written into my contract and two months after installation and payment, I contacted my sales rep who told me he made a mistake and I wasn't eligible. He also told me he would take care of it. After numerous texts, I finally called the office. They took my information and I never… received a return call. This is terrible customer service! If the sales rep made a mistake, the company should cover it especially since it was written into the contract. Next stop... small claims court and the Better Business Bureau.
