Customer Story in Lake Oswego, Oregon

A Lake Oswego Customer Trusts Four Seasons to Improve His Home's Air Quality


When Dexter needed an HVAC solution in his basement, he began shopping around for reputable contractors in Lake Oswego. He had different technicians come out to inspect his home and come up with quotes. While he held off on scheduling service for a while, he eventually decided to go with Four Seasons due to our competitive pricing, easy financing options and our tech Adam's impressive professionalism. As soon as Dexter signed off on the quote, our NATE-certified installation team got to work and completed the job fast.


Four Seasons' fully stocked white van showed up at the scheduled time, and the installation team worked quickly and efficiently until the job was done. Dexter was satisfied with how it turned out and thought our financing options were the best around. He's enjoyed the quieter operation of his new HVAC unit, and the air filter has left his home feeling much more comfortable, even substantially improving his allergies. We're glad we could help you breathe easier, Dexter!

"The install crew were on time, respectful and finished the job early."

"Adam was the most thorough, personable and professional of the 5 individuals that visited our home to provide a bid. The install crew were on time, respectful and finished the job early. Would have liked to see a bit cleaner finish in a few places, but it's an appliance in the laundry room and function matters most. Financing options were the best that I saw. Air handler is much quieter than the unit it replaced, apart from a squeal from one of the lines not solved for. Our home feels much more comfortable, and my allergies are substantially better between keeping the house closed up + better filtration. I can breathe through my nose for the first time in WEEKS."
