Our 12-year-old Slant Fin boiler was not running. An issue with the gas valve.
A different company (which shall remain nameless) told us they could install a new gas valve. It would take 'take 2-4 weeks' (We were at the end of November). They did not seem to want to fix our boiler ... but were very keen to sell us a new one.
Instead, we called Ketteringham Heating. They understood everything immediately. Jason found the part within a few hours and told us that "it will be fixed by my team (Matt)".
The very next day, before lunch, it was fixed!!!
Matt (the technician) did a great job and explained everything.
Without Jason and Matt, I might have been obliged to buy a new boiler.
Based on my experience, it is difficult to find a better service than Ketteringham's when it comes to boiler maintenance in the GTA.
Bravo!
A grateful customer.
