He fixed my issue as best he could, showed and explained to me what had gone wrong, and returned with two other guys to replace my furnace by that weekend. Not only was I able to keep my house warm between his service visits, the installation was done well before I had to go to work. I greatly appreciated the punctual, friendly service.

They were quick, kind, and reasonably priced! We will be calling them for all our HVAC needs!read more

I very seldom write a bad review because I believe that anyone can have an off day. However, I…read morefeel I need to share my story with anyone thinking of calling this company for their furnace needs. We bought a house back in 2012 and were given a home warranty that would last one year. We've renewed this warranty every year and up until last year they would always send out All-Knight when our furnace would act up. Our furnace would act up about every four months. It wouldn't blow out any hot air, it would try to kick on but just couldn't. We would call the home warranty folks, they would send out All-Knight. The tech would go in the basement, hang out for maybe ten minutes and say it was all fixed! It was just a dirty heat sensor. And the furnace would work again.....for about four months. We dealt with All-Knight so often that we were on a first name basis with the receptionist, Brenda. We almost invited her over for Thanksgiving!! After YEARS of dealing with this, our home warranty company finally switched to a different HVAC company. Last fall the furnace wouldn't work as usual, we called like we always did. However, this time they sent out an unfamiliar face, a gentleman who was not from All-Knight. He took one look at our furnace and asked "Who has been messing with this furnace???" As soon as I said All-Knight he recognized the name and said I am not the first customer to throw out that name when having constant furnace issues. I told him that it should only take him a second to fix because it's always the heat sensor according to All-Knight, and he just shook his head. He worked on it for about 30 minutes and it has never broken since. It's been over a year!! I think the evidence is pretty clear that the home warranty company as well as us, were scammed all those years. I would avoid these guys at all costs!! Or your cost may be way higher than you could ever dream of!!

OK! Let me tell you about our experience! We are beyond pleased!…read more We had our ac go our Sunday afternoon before 7/4. We scheduled an appt with a different company in Pickerington, OH for 7/3 only they scheduled us incorrectly in the computer for the following Friday. Naturally, with our home pushing 90degrees, I was pretty intense on the phone when I called to inquire about our sevicemans tardiness; so I cancelled and started hunting for a new company to come fix our ac. I came across LFR Maintenance and on a stroke of luck, was scheduled for the same day (7/3)!! They had a technician out to our home within 20minutes and it took him 15mins to fix our problem (a common capacitor burnout). I was so excited that they were able to repair our ac unit and within such short notice! That's absolutely incredible; our tech, Ross, was professional and efficient--he finished within minutes before a downpour! Thank you for your awesome service!

Robert came and diagnosed the issue and made recommendations on the repairs. I had to wait for three weeks for the new gas valve and pilot light assembly, which luckily the water heater did not fault out more than once during the wait.

Robert communicated well with me when I called him during the parts to deliver.

The big name company with fancy commercials on TV And took monthly service amounts to "make it easier" for me. 2 years ago they said that I needed to replace my ENTIRE air conditioning unit that they had been servicing for almost 10 years. The unit was only 11 years old at that point. They tried to sell me a new one for $9k !!!! I decided to get a second opinion and had 3 different companies come to check the unit. THERE WAS NOTHING WRONG. They said someone had loosen up a valve and all the antifreeze was gone. Needless to say I was almost the victim of fraudulent business practices. I dropped my contract and have been with KNOW ever since - you WILL NOT find a better HVAC company with amazing customer service and integrity. Ask for Scott! I have referred 5 people since then and they all love the service.
