If you live in an older Toronto home, there is a good chance that a boiler heats up your home and even your hot water. Boilers are still a perfectly efficient way to heat homes, so it's important that you have a technician that can repair and replace this heating unit. While some HVAC companies no longer do work on boilers, at Rose Branch Mechanical we have an experienced team of technicians who are specially trained to fix and replace boilers.
