Hear from the homeowners and businesses who rely on us for expert solutions.
    Appreciate the professional service!
    “John from Master Plumbing replaced my water heater after my old one failed. Despite it being after 4 pm, he was able to quickly pick up a replacement unit and install it the same evening, staying late to complete the task. He also went above and beyond to clean up the area around the old water heater, as well as my driveway after some of the water from the old water heater leaked out.”

    We feel confident with this team to help us!
    “We had a problem with our HVAC system leaking from the condensate and the blower and Matthew E was the best person for the job! He was professional, quick, and helped us understand what went wrong and got the items replaced in no time! We signed up for the Green Club for regular maintnence.”
    Kendal A.
    I felt every detail was taken care of when they went out the door.
    “Matt and Sean came to do my fall furnace check this afternoon and I want to say I was very pleased. They checked the airflow that I never had done before, cleaned the drain that was covered with corrosion materials, and replaced the humidifier filter with a fresh one I had. I felt every detail was taken care of when they went out the door.”
    Phyliss K.
    Very personable and I highly recommend him for any plumbing needs you may have.
    “Great experience with John. He is very knowledgeable and gets the work completed in a timely manner. He discussed everything he would be doing beforehand and told us the cost. When he was done, there was no up charging. The cost was exactly what he said it would be.”
    Elizabeth D.
    I will definitely recommend this company!
    “We had a water softener installed. I called Master Plumbing, Heating, and Cooling at about 8AM and we had a water softener installed by 12:15. Bill was our service technician. He was so very polite and respectful of our home! ( He wore shoe coverings) Bill explained everything extremely well. We bought their Green Club Membership, for a few dollars more, which will cover plumbing, heating, and cooling. Our systems are well over 25 years old, so over the long run this membership will save us a lot, Thank you Bill and Master Plumbing, Heating & Cooling.”
    Diana P.
    Thank you!
    “Very professional service. Both guys were very understanding and answered all our questions. I highly recommend. Appreciate the great communication too when they let us know they were coming over and when they finished the job. Also thought it was kind they offered to sweep up the area. Thank you!”
    Jayna A.
    I would definitely call them again!
    “Had John & Henry from Master Plumbing & Heating here, say before Thanksgiving to replace my water heater. They did a fantastic job and had it installed and running in 4-5 hrs. Both were very professional and cleaned up after themselves, as well as took the bad heater with them.”
    Karen R.
    We'll definitely be using Master Plumbing going forward.
    “ohn from Master Plumbing installed a new water heater for us last week. He was prompt and thoroughly explained all of our options in the quote. It was nice having the same person doing the quote and installation. He installed it the same day. We were so pleased, we had him return to fix some previous issues with water temperature and pressure. He fixed it in no time at all and was cognizant to keep the price as reasonable as possible.”
    Chad G.
    Would definitely recommend him and Master Plumbing.
    “John came out to do my annual plumbing inspection; caught and fixed a few things (had pictures of discrepancies), cleaned out my tankless hot water heater at no charge.”
