Our licensed pros diagnose the problem thoroughly and make sure your plumbing is back to working like it should—without repeat issues.

Honest Plumbing & Air has been providing the best in HVAC and plumbing services to residents across Central Texas. Above all, we operate on the belief that honesty is the best policy. We will take the time to properly assess your specific situation and we will not overcharge you for unnecessary work. You can rest assured that when you call Honest Plumbing & Air, you're getting a professional technician who will be straightforward with you every step of the way. Our team will effectively diagnose your air conditioning, heating, or plumbing problem, without exaggerating the truth.

"Beware! not so honest. I had a air conditioner that would not start earlier this year and while he was here, I asked about having some general maintenance completed at the same time. I was told it could not be done at that time but the tech suggested that I purchase a maint. package that they would come out twice a year to do general maintenance on the units. He stated that they could do in a week or so, it turned out to be over 1-1/2 months for the 1st maintenance but I should clarify that it really isn't much maintenance but a opportunity to pay them to do a quote for additional work. In addition to this, one of our units was not operational arrived, before he would even move a finger I was required to sign a document for work in the amount of around $340 which ended up taking the technician 15 minutes to replace a blown fuse and loose wire, they charged $116.99 for the fuse (cost $0.1469). Not so honest, much different story from when I initially used them several years ago. "

Locally owned and operated plumbing company focused on residential and commercial installation, service, and repair. Our two Master Plumbers have over 50 years of experience. Let our service exceed your expectation.

"I needed to replace old water heaters and also had some other plumbing work in my home - caulking and taking the wobble out of some recently installed toilets. I looked to Angi's to get some quotes, and Matthew was quick to quote the work and schedule. He was detail oriented explaining what was needed, and very tech savvy being able to provide quotes over email and the app with photos and details compared to others, in my experience, who need to come to the home first and don't seem to follow up well. I got master plumber Zack who was respectful, nice, clean and considerate of scheduling water cut offs with the family's needs. There was another customer emergency, and they were able to finish the work so we had hot water and come back the next day to finish the rest at a convenient time - showing me they really cared about their customers and triaged appropriately given how essential running water is! Highly recommended."
