About UsOur clients say it best...
“Walt Cook and Northstar Heating & Cooling has been our HVAC service provider for years. We find his pricing fair and his customer service excellent. I would highly recommend Walt and his company for your HVAC needs.”
Doug W. Lynnwood, WA“We had a central exhaust fan go our on our small office building. Most of the companies we we contacted were too busy to come out for weeks, and wanted us to sign a service contract to do any work at all. Walt came out looked at our situation and quoted us to repair what we had, or to replace in kind.”
“We decided to upgrade to a more efficient system and he redid the quote for that. He then sorted out a control system for the more efficient system. He was very professional throughout. He will now be our tech when we have a problem with our HVAC equipment.”
Mark BSeattle, WA“Through Walt’s maintenance, he has kept our repairs to a minimum and extended the life of some older units. Walt is very conscientious, solves specific problems and has excellent communication skills to discuss and educate the tenants on their thermostats or repairs needed.”
