We had an amazing experience with Frank. He was responsive, friendly, transparent, efficient, and priced very reasonably. Definitely give him a call if you have any plumbing issues. He diagnosed the issue and quickly replaced the part needed for repair to our hot water. Great customer service!

We have used Mc Intosh Plumbing & Heating for many years. He has always responded to our calls quickly and followed through with visits in the least amount of time. All the work that was done was of the best quality. I highly recommend Mc Intosh for any plumbing or heating needs.

Frank was a pleasure to work with. I had my boiler and oil tank removed and converted to gas. The work went quick with no mess. I was completely at ease with his expertise and professionalism.

LOOK NO FURTHER…I cannot say enough good things about Frank McIntosh! He is a very experienced plumber with high ethics. He always diagnosed my plumbing issues correctly. I remember one incident specifically when my upstairs shower was leaking water down into my kitchen. Frank said he would need to open the back splash behind my stove to determine the actual location of the leak. Based on his expertise he only removed 3 tiles from my back splash and voila! This was exactly where the leak was. Any other plumber would’ve demolished my entire backsplash. This was only one of many instances where his expertise saved me money and avoided extra unnecessary repairs. Frank has been my plumber for over 20 years, if something is out of his scope like a cesspool issue, he knows to step back and recommend the right person for the repair. Frank is no nonsense, some may view him a bit serious, a no small talk guy but I happen to like this and throughout the years we’ve established a friendly relationship. I recommend him to all my friends and family, they too are very satisfied with Frank. I’m someone who is very picky and hold people to high standards so for me to write such a glowing review its because he absolutely earned it!

Do not hire this company. He told me he was familiar w radiant heat but then he could not be bothered troubleshooting the various zones. He told me the thermostats were not working. He bypassed two thermostats. He told me I needed a new circulator but he did not have one on the truck. He came back the next day, replaced the circulator. I did not have heat in the first floor. He said it was an electrical problem and he couldn't help me. He left w the two bedroom zones on continuously (no control) and no heat in the house. He overcharged me for two service calls. Billy Gs heating and a/c came out a few days later. Within 20 mins he told me the electrical was fine. The upstairs thermostat needed two aa batteries. He bled the whole system and I now have heat, controlled by thermostats, in the whole house. DO NOT HIRE MCINTOSH! CALL BILLY GS!!
Response from Company:
While I value all feedback, this review does not indicate what we did at this job. I was there myself and I am an expert in radiant heat, but I was never at this home before and needed time to get familiar with what zones served different areas of the home. We diagnosed a bad relay which was caused by a bad circulator pump. We repaired the relay but I had no pump on the truck the first day and it was too late in the day to get one. I also had the customer turn on all heat zones from her thermostats. , She did not let us have access to the house that day due to covid concerns. 2 Zones were not activating by the thermostats at all. I jumped them out overnight to see where she would get heat. We returned the next day with a pump and replaced it. When bleeding the system we found a bad mixing valve which we replaced. I went upstairs to check the thermostats. There was the only access to the 2nd-floor thermostat which I took off the wall and jumped the wires with no change at the boiler. That thermostat tested good. The first-floor thermostat I was told was buried behind furniture and presents and could not be accessed. I never charged her the first day and only gave her a bill at the end of the 2nd day this was for the 4 hours we spent and materials there was no service call added on . When we left off I told her the thermostats would need further work and suggested she contact an electrician as I believed there was a wiring issue. We bled all the zones a second time on the second visit and asked her to see what was operating and if there were still issues. Radiant heat takes 24 hours to get fully hot so it was not apparent that day if everything was getting hot. She paid the bill and never mentioned it to me in any way or never contacted me afterward to let me know she was unhappy. We strive to make all our customers happy and I am truly sorry we did not in this case. I would have appreciated the opportunity to make the customer happy before she decided to leave this review.
