Testimonial Post-It Notes

We don’t like to toot our own horn, so we let our customer do it for us.

Your prices are more than competitive and you were one of the very few who got back to us for a “look-see” and then a written quote…the others didn’t even bother! Your Daikin Room AC/Heater is awesome and so was your craftsmanship, installation, clean-up and sense of humour! You and your business are a 10 out of 10 in our books!

Nolan is friendly, very approachable and able to explain how different components of the geothermal systems works. I greatly appreciate someone like Nolan who intuitively understands that an emphasis on technical detail to communicate with a nontechnical person is not what some customers need.

We recently had Sub Zero Heating and Cooling install an on demand hot water heater to replace our ailing hot water tank.  We are pleased with their work, expertise and efficiency. They consulted with us carefully, gave solid recommendations and most importantly listened carefully to what we wanted. During the install both gentlemen consulted with us when unexpected issues arose and gave clear options as to how best to proceed.  We are thrilled with the new heater (and bonus space in our little house) and will continue to recommend Sub Zero Heating and Cooling to our friends, neighbours and anyone we encounter who needs caring, knowledgable and efficient installations.

Nolan from Sub Zero Heating and Cooling is very professional and delightfully charming. He walked me thru the entire process of having air conditioning installed in our home. The Sub Zero Heating and Cooling installation technicians were clean, efficient and polite. I highly recommend this company!

Nolan, you are a rare gem! Your knowledge, speed of installation, cleanup and especially your sense of humor made it all so worthwhile! Your follow-ups have been so appreciated.  Jay & I give Sub Zero Heating and Cooling a 10 out of 10!!!
