Canro boiler services were genuine life savers. I was stuck without heat overnight and they came by and got my boiler running again. Fast, professional, and genuinely caring about their customers. Could not recommend them more highly.

Five stars for Canro Boiler Service and Repair. We needed a replacement of a 30-year-old boiler. A new high-efficiency unit was installed professionally and efficiently. The difference in heating performance and cost savings has been remarkable.
