"Jaymie first visited to review our need for correcting a pre-existing faulty installation of a tankless water heater. He grasped our concerns at once, joined us in brainstorming a relatively simple solution, and produced a financially reasonable bid on the spot. We accepted it as far more reasonable than other bids. He arranged to have the work performed by his company within a few days. At the appointed time, Jaymie himself arrived to do the job, which pleased us greatly since he already knew exactly what needed to be done, making it unnecessary to brief a new workman. He is a very competent, friendly, and helpful person. We would not hesitate to call on him for any future plumbing needs."

"Excellent from start to finish. Arrived on time, replaced our old water heater with a new one, left everything very clean and, from what I can tell, provided excellent workmanship at a very reasonable price."

"August 25, 2026 Rated 5/5, I am writing to express my appreciation for the excellent customer service provided by Horacio Parker, a plumber with Beutler Air Conditioning and Plumbing. On August 25, 2026, water was leaking from my water heater onto the garage floor. Mr. Parker responded promptly, listened attentively, and showed patience, empathy, and understanding of my concerns. He was courteous, polite, friendly, and maintained a professional, positive attitude throughout the service call. Mr. Parker shut off the power and water, drained the old 75-gallon Bradford White water heater, and installed a new 75-gallon Bradford White Energy Saver water heater. He communicated clearly and showed me how to shut off the water to the house and turn off the water heater to help prevent future flooding. Mr. Parker is an asset to Beutler Air Conditioning and Plumbing, and any company he provides service to Lovevasia Bey"

"Furnace blower would't run. James explained the problem & installed the condenser-which he had on the truck. He also explained some "issues" that might come up in the near future. He performed some maintenance that was overdue. Seemed very thorough & most importantly, the heater worked properly when he was done!"

"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."
