What our customers are saying

  • Northern air found an issue with my furnace that was installed by others. Kyle found a concerning issue and fixed the problem. Happy he checked it out even though he was here for another problem. Thanks 669-heat and Kyle.
  • The gentlemen who installed our on demand water heater did a great job in a timely manner.
  • Excellent knowledgeable service on the furnace. Friendly manner, did the job efficiently, and left the place cleaner than when he arrived. Well done.
  • Thank you to the technician who was polite and on time. He worked on cleaning my furnace and HRV. The area was left clean and tidy. Very efficient work!
  • Fantastic service, communication and pricing
  • Ariel, was polite, efficient, and answered my questions regarding the furnace. She did give me great service and if I needed any assistance I would ask for her services.
  • Kyle assessed our problem expertly and was efficient and professional. He realized our situation was rather urgent and came back the very next morning to finish the job. Even arrived at the door greeting us with a smile. Wonderful! Thank you so much! Love 669 heat!
  • Ariel B was excellent and demonstrated very good knowledge & professionalism!
  • Kyle came to fix a concern with my relatively new gas insert and discovered a separate issue with the fan. Instead of rebooking another day, he addressed the concern immediately, which was time-consuming for him. He also took the time at the end to clean the glass and other parts, to make it look like it was just installed. I find customer service to be lacking in most industries these days, so a big thank you to Kyle and 669 heat for fantastic customer service.
  • Kyle and Dominic were very helpful, suggested I turn water heater down a little, very enjoyable and positive service visit. I also appreciated the recommendation to set up a service contract to make sure our equipment is working at top efficiency.
  • We were very impressed with the today's maintenance service by this knowledgeable and friendly young lady.
