Your Home Town Professional! The 1-800-PLUMBER® + Air history has a unique journey that laid a foundation for the strongest brand within the industry. In 1999, the 1-800-PLUMBER® name and phone number was secured, leading to the well-known “Our Name is Our Number!” slogan. In 2010, Mark Collins joined the 1-800-PLUMBER® brand as a franchisee and then in April 2015, they purchased the 1-800-PLUMBER® brand and created the foundation needed to grow 1-800-PLUMBER® into a household name throughout the country. Today, 1-800-PLUMBER® + Air locations can be found across the US, and our franchisees strive to make us the highest-quality brand in the industry through honesty and integrity, professionalism, and craftsmanship. Our teams achieve this by doing what they say they will, always telling the truth, training their team members to always conduct themselves in a professional manner, and only utilizing skilled craftsmen within the industry

"Contacted them for a second opinion / estimate on some work another outfit in town had recommended. They told us what actually needed to be done in the near term, and what work could be left for later. The other place wanted 9 grand to do everything. The 1-800-Plumber guys did the necessary items for less than $1000, and did them well and quickly!"

"This has been the most frustrating experience in my life. They said the project would take a day and a half. It has been 2 weeks and there is NO end in sight. They do not believe in keeping the customer informed about the status of the project. They say "somebody will contact you- but nobody does. They left the work site in an unsafe condition. Repeated request to remedy the situation have been ignored. First and last time user of Angie's services. I am non verbal. NO PHONE CALLS. I want to see someone in person ."

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. "

"DO NOT USE THIS COMPANY. During the process of doing the work, they damaged my property. They said they would fix it, but I called many times and continued to get the run around. Finally they had someone come out to paint, which did not cover the blue dye or fix the issue with the stained flooring or base boards. I have continued to call and been told a manager will reach out, which they never do. I have filed a complaint with the BBB."
