"Installed ok and he left ! No complaints!"

"Great Experience. I was concerned about the 22 yr age of our air conditioner able to keep working and wonder if a long wait time to get a product shipped like refrigerators last year, I called for a quote and within a week it was installed and working! Installers worked tirelessly until their work was done, clean and neat!"

"Very impressed with the professional appearance and demeanor of the installers. They initiated a series of pre install checks around the home that solved some issues and found a few problems that needed to be solved before they started. On top of going the extra mile, the install was successful and I'm a very satisfied customer. The manager was responsive and accommodating. Highly recommend Dunn One Hour Plumbing, Heating and Air Conditioning."

"The selection process took a long time to find the right plumber. I talked to Steve, he really made me feel at ease about the company. Plus there was a coupon on Angie's list for the work. Scott was the plumber that did the install. He was patient and explained everything he was doing. (I always watch over the guys shoulder to see what is being done.) Everything went perfect, removal, install, cleanup, etc. It is great to find this kind of company nowadays. Keep up the good work."

"Both the estimator Kevin the two installers who visited my home were very professional and kind. They answered all my questions and provided a very reasonable price for the installation of the attic insulation. I feel I was very informed on the federal rebate that was available for this installation, as well as on the recommendations of quantity of insulation I needed per residential standards and codes. I would recommend Anton and will use them in the future for my HVAC needs!"

"Able to install on a timely basis. Friendly, clear, and reasonably priced."

"Glen the repair man was fantastic. Installed new kitchen faucet within one hour. Quality workmanship, clean and neat. It was an honor to meet this distinguished Marine Core Vet."

"Jacob and Cody have been amazing to work with. We originally hired them to repair our stairs and have since contracted with them to install our kitchen tile floor, install electric in our kitchen island and to repair some of our drywall. Their team is very professional, their estimates are accurate and they do quality work. We plan to hire them again when we remodel our bathrooms."

"Had some filters updated. Glad to have a great HVAC guy!"
