Our 25+ yr furnace died in the early morning and Nick came by to assess by early afternoon. We had a new HE furnace installed by 11pm that same day which is amazing considering the requirement to drill out the intake and vent we didn't required before.It wasn't fun being without heat working from home on a super cold day, but Superior came through and we've got a great new unit to serve us for years to come.Thanks Superior!

Very satisfied with the furnace repair from Superior HVAC North York. The technician was knowledgeable, walked me through what caused the issue, and made sure everything was running properly before leaving. Reliable and honest service.
