Common questions about boiler service

What makes boilers different from furnaces?
Boilers heat water and send it to radiators or baseboards; furnaces heat air and blow it through ducts. See our guide on hydronic heating for how water-based heating works.
How long does a boiler repair take?
It depends on the fault and the parts needed. Once the technician has found the cause, we tell you what to expect before the work starts.
Do you service boilers in commercial buildings?
Yes. We service boilers in offices, retail shops, restaurants and apartment buildings, alongside rooftop units and split systems.
