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!

I had no clue what was wrong but they came in and were super easy to book, very cheap in comparison to other companies but I’d say they’re worth three times the amount I paid. I cannot recommend them enough. If you want good quality work. Ask them
