Decades of Service, Thousands of Smiles

Hear from the homeowners and businesses who rely on us for expert solutions.
    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.
    My entire experience with Master Heating, Plumbing, and Cooling was a 10 out of 10.
    “Bill M was my service tech, I don’t know if he was a plumber but he certainly installed my sump pump with absolutely no problem. He explained to me in the beginning that my sump pump “could fail” but did not try and pressure sales me into anything. What he said made me comfortable in his knowledge and I trust him. I did not get the idea that he was just trying to make the company money by upselling to me either. So exceptional work from Bill M. I’d also like to say I had a couple interactions with the office staff as well. Taylor and Allie are top notch as well. My entire experience with Master Heating, Plumbing, and Cooling was a 10 out of 10. I will continue to use them in all my heating, plumbing and cooling issues that arise.”
    Michael S.
    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.”
    Eric F.
    Bill was outstanding, friendly, and very accommodating!
    “Bill came to our home to do a full plumbing inspection. Bill was very thorough and showed attention to detail. We noted to technician that we had a concern with our shower drain. Bill was right on it! He recommended we consider using a snake on the drain. Bill adjust the price based on the fact that it was an easy job to complete. He also tested our water and reviewed the report with us. Bill was outstanding, friendly, and very accommodating!”
    Tana L.
    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.
    I would 100% recommend Master Plumbing Heating and Cooling
    “I called in the AM regarding our central air not working and spoke with Taylor who was so friendly and let me know they had an appointment in the afternoon. Maddie then kept in contact with me as to when Madison & Jordan would arrive. Madison and Jordan were very friendly and got to work right away and had the unit working quickly. Everything went smoothly and I cant say enough about every person I was in contact with. Such a great experience! Thank you all so much!”
    Denise E.
    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 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.”
