Testimonials
Always great service from these guys! Jose and Jose (2 different guys) are awesome and so respectful. They explain everything well and I have always been pleased with the service for our heater units.
Sarah T.
North Bay Air Systems is as good as it gets! Our air conditioning unit went out and another company came our a took 5 minutes to come back with a recommendation to buy a new unit ($8000+). I called North Bay and they came right out and diagnosed the problem – a small part was all that was needed to repair the system!
Then my heater unit went out – same thing – Ron at North Bay Air Systems said we had a choice of either buying a new unit or repairing the one that we have! He found the part and we are back in business!
Efficient, honest, reasonable and without a doubt, the customer comes first!
