“Brian is an absolute joy to work with. Professional, reliable, full of in depth knowledge and takes such pride in his work. I was so impressed with how clean he made my vents, and the air quality improved 100%!“

“Brian is knowledgeable, professional, and hard working. My heater change out was an example of the way it's supposed to work. Brian sells and installs quality products and his work is top notch. My house was left clean when finished and other than the new unit installed you would never had guessed he was there. Trust is a huge thing in the service industry and Brian goes above and beyond expectations in that area. Couldn't ask for a better local service company. If you have duct cleaning, hvac work, AC or heater repair or install, you would be hard pressed to find anyone better. Super impressed with Brian's service and care.Services: Heating system maintenance“

“Great job with replacing a venting pipe! Would definitely contact them in the future.“

“Kopp Plumbing is QUICK! They responding quickly, fit me into their schedule quickly, and got the work done quickly. The work looks great and doesn’t leak. They left the work area cleaner than it was when they started. It also ended up being $2,500 LESS than what another plumber quoted me.“
