"They installed a furnace and had to keep coming back to adjust it and even replaced a part. The warranty ran out a year later. But now, a year and a half later, they replaced it free of charge with a different brand."

"We got a brand new Trane, so we got the most state-or-the-art, most current unit, I think we also go it financed, we're paying for it on our escrow account, because we're financing it. I think the unit itself was maybe $10,000 or $12,000 and with the installation and everything, I think it ended up being close to $16 or $17,000. I thought it was too expensive, but my husband thought the price was reasonable. It was great. They were fantastic. They were knowledgeable. They were very clean. They were wonderful."

"Kermit and his son showed up quickly on the same day I called on a Saturday to replace my water heater and expansion tank. They were both very friendly and professional and performed the exact service I needed without any up-sells or other kind of pressure like a more expensive tank with unnecessary additional warranties. They replaced the old water tank and installed the new one very quickly and I was very happy with the work. Very efficient and professional and I recommend for any plumbing job. Am very happy with my Bradford White 50 gallon water heater and it has been working like a charm for months. It seems to be performing better than the old one too as the water heats up faster and is hotter at the same setting we had before. Thanks a lot Kermit!

"The team of four was very professional and performed an excellent job in a record period of time. Just one day to take the old furnace away, replace all the old boots and duct work and install the new furnace. They paid a lot of attention not to damage or dirty the floor/carpet. I am very happy with their performance. They may not be the cheapest on the block but it was all worthed and you only have to do that once in your lifetime."
