I could not be happier with the work Gill’s has done at my house and business. Brett, his son, and everyone else at Gill’s are prompt and friendly. More importantly they do good quality work and they cleanup before they leave. Thanks again!

Chad repaired our non-working 27 year old furnace. He explained, very well, the issue then proceeded to fix problem. THEN he did a thorough inspection, cleaning, and ended by assuring us that even though older our furnace was in good shape. Very pleased!

Had a moisture problem in my attic, called Brett and he came over. I explained what was going on in my house and he knew immediately what the problem was? Clogged chimney. He CLEANED out the chimney, tuned up my furnace, problem solved. You couldn't ask for a nicer person. PTL.

I'm out of state and my daughter and her friends are staying at my house. She called me last night and said the furnace wouldn't turn on. I had used Gills once before and thought they treated me ok so I ended up telling her to call them. They showed up the same day, were fair, explained it to her and it was VERY affordable. I will never call anyone else again. Thank you!
