Customer Story in Lake Oswego, Oregon

Emergency service done ASAP

Problem:

When homeowner Caitlin needed to have her heat pump repaired ASAP, she asked around the Lake Oswego community for referrals. She wanted a good price without sacrificing quality or speed. After hearing good referrals for Four Seasons, she reached out to us for a quote.

Solution:

After our expert Comfort Advisor took a look at her heat pump, he figured out that the heat pump was over 10 years old and needed to be replaced. He then thoroughly explained financing options and gave Caitlin a personalized quote on a new heat pump.

By the next week, our team had completed the heat pump install, explained what work had been done and taught Caitlin how to use her new heat pump.

"Very responsive"

"We had our heat pump go out on a Friday afternoon and in the next hour, someone was out to get us a quote on a new one. He explained everything so well and helped us understand all the details! After we decided that it was the right decision that evening we have very responsive calls to confirm financing and get guys out here the middle of the next week! They were very responsive and easy to get a hold of. It was an awesome experience even if it wasn’t the best situation to initiate it"
