6 days of terror working with these guys. During winter storm, gave us the wrong diagnosis of our…read morefurnace problem, sent us wrong parts even though we told them multiple times to make sure they sourced the right part. Refused to help us despite assuring us they would fix our heating problem because it had been several days. Didn't honour the warranty and their suppliers don't even care to deal with them leaving everyone hanging for another 72 hours.

Job: provide, install new water heater and remove the old one…read more Very satisfied with the service provided by Andre and his collegue. They are very polite and friendly, working fast and clean. The price of the water heater was really good. The job was done in time and a small "hick-up" (due to my floor heating piping) was resolved fast. I strongly recommend them.

I have used Martino since 2011 with no issues - professional service and I have always had a great…read moretechnician. In February 2026 C, a Martino employee, contacted me to book my annual furnace cleaning and we booked for February 26. Nobody showed up, no phone call, nothing. When I was able to get hold of C he told me that I was suddenly no longer in Martino's service area. I was shocked that there was no communication and that they would just drop me with no warning. Last week I was contacted by J, a Martino employee, to once again book my annual furnace cleaning. I explained what happened last time when C contacted me. J checked and confirmed that I am off their client list - no warning, no recommendations for a new company to service my heating and cooling equipment, nothing. If you are a loyal customer, be aware that this could potentially happen to you. I really thought I was set for life with a great company. I am beyond disappointed at being so unprofessionally kicked to the curb like this, do better Martino.

I had a service man clean my tankless hot water heater 6 months ago and apparently he missed…read morecleaning the air intake filter. Consequently the filter clogged up and the hot water heater stopped working. I called Martino HVAC to send a service man over and Tom Scrannage identified the problem, removed the cover and the screen and cleaned the air filter and got everything working in short order. He also noticed that the hose for the overflow was the wrong one. He came back the next day ( Friday evening at 6:30!) with a new filter and nose and now we have piece of mind that everything works! I highly recommend that you ask for Tom when you are requesting service.
