Customer Story in Keizer, Oregon

A Thorough Install Job Wins Over a Wary Customer


When Keizer homeowner Troy needed a furnace installed, he contacted four HVAC contractors in the area for bids. He wanted an HVAC company with a high level of professionalism that would give a detailed overview of what work would be done and why. Also, Troy wanted a contractor that would meet his cost expectations without sacrificing quality work. After reviewing four bids, he went with Four Seasons.


One of our experienced Comfort Advisors went to Troy's home to present the pricing options. Troy was pleased that our installation price beat our competition's bids by $1500. Our team determined the best solution for his heating needs was to replace his old furnace and explained that his old furnace was not properly sized for his house.

Troy was impressed that on install day our technicians were above and beyond professional. They laid drop sheets, removed their shoes when they entered Troy's home and used zip ties to keep everything tidy. Troy now recommends us to anyone in the Keizer area.

"The only contractor who actually explained"

The most professional business I've ever hired. They were the only one who actually explained what I needed for my heating needs. I got the furnace that was correct for my house (my old one was not designed for my house) for an installed price that was about $1500 less than the other 3 bids.

We thought we had some mice damage to some of our ducts under our house and for no charge [the tech] crawled under there, determined there was definitely damage and fixed it to get us by until we could have the ducts repaired correctly.

Very happy with their service and professionalism and I would recommend them to anyone!!
