Holt Plumbing & Heating Inc have always been on time. They're very professional and very respectful of my home. They put drop clothes down and always wear booties, whether they're going to the basement or the main part of the house. They're genuinely friendly and courteous. I've been with them for about fifteen years and I believe I chose them because they were close to my hometown. Holt Plumbing & Heating maintain my furnace and AC every year, and they have installed my central air conditioning unit as well as replace some piping in the basement. They're currently scheduled to put a first-floor laundry for me so they will put in new drain pipes. I always know I'm safe and that my house is safe. They're always exceptional and there are never any surprises. The quotes are always reasonable and would not think of using anybody else.
