Our combination boiler unit needed replacing after 18 years. We had no idea what to look for until we spoke with Larry of L&M. He was the 3rd contractor to come out and he knew his stuff. He didn't try to sell us an air handler because he said the one we had was working fine (basically they almost never die). Other contractors quoted us almost twice as much as what Larry did and that's because they wanted to change out the entire system....air handler and all.
Larry came out the next day after we spoke with him. He recommended a Navien combo boiler. He gave us his price which we knew was very fair. Him and his partner had it installed within a few hours even while having to work in a small boiler room.
They were both fantastic and I would highly recommend them. Both knew what they were talking about. Straight shooters and no nonsense. Exactly what you're looking for in a heating and air conditioning contractor (or any contractor for that matter).
I highly recommend them and I'll post a picture of our new installed Navien. Many thanks, Larry. You guys are awesome!
