Customer Story in Hillsboro, Oregon

Better Heating and Air Quality Left This Hillsboro Customer Happy


Heather had been dealing with inconsistent heating in her home for months, and it was also affecting her indoor air quality. Despite her efforts to maintain her furnace, it was clear a replacement was necessary. After researching several companies in Hillsboro, Heather chose to contact Four Seasons. She scheduled the furnace replacement to address both her heating and air quality issues. Our polite and friendly representative, Amy, answered all of Heather's questions about air purifiers and offered a special promotion that would save her money on the installation.


Stephen, Mike and Tim arrived at Heather's residence at the scheduled time and were ready to get to work. They efficiently replaced her old furnace to address the heating concerns and installed an air scrubber to improve indoor air quality. Once they finished, they answered her questions and provided clear instructions on operating the new furnace and thermostat. Before leaving, they diligently tested and verified that all equipment was working perfectly. Heather expressed her gratitude for the exceptional service from our whole team, including the professionalism and helpful assistance offered by Amy in the office. Now a loyal customer, she gladly recommends Four Seasons' services. Thanks for choosing us, Heather!
