We were having a problem with our heater. The fan wouldn't shut off even though the heater did. This would then cause cold air to be blown through the house. I'd called another company about the same problem the previous winter, and they told me I needed to replace a part on the main board. They replaced it, and the same problem happened again shortly thereafter.
The third time it happened, I thought I'd try someone else. I called 4 Seasons, and Alex came out for the call. He determined that I simply needed to change the filter. He was correct. The heater and fan have been working properly ever since. I really appreciate that given the fact that I was upfront and disclosed what the previous company had told me was the problem when it happened before, that he could've charged me a ton. The service charge was very minimal, and Alex wouldn't take the extra money that I offered to pay for his time. Thank you Alex and 4 Seasons! We will definitely call you again!
