Stan's Heating And Air Conditioning

I used to be a loyal customer of this company. I bought my new furnace in 2013 and ERV system in 2017 through this company. The furnace they installed in 2013 caused some damage to the exterior wall of my house in winter 2014 due to the very short exhaust pipe they installed. When they installed the ERV system, they drilled two unnecessarily large holes through the wall of my house and then covered them with lots of caulking. While I was unhappy about those incidents, they were relatively less significant, I did not complain anything.

Since last winter, I found the air circulation of the furnace was very weak. This was not a big issue in winter because the hot air in first floor went up naturally, so I didn't contact the company. However, in May this issue became significant because our second floor became very hot in evening. We called the company and told them the issue. Specifically, we emphasized the issue existed in both summer and winter. But the person who answered the phone insisted that it was likely caused by our A/C and they had to send somebody to check. Their technical staff came and checked. They found no problem with A/C. Instead, they said it was caused by the filter. They said I should use 4" filter and change it every month. However, when they did the regular maintenance last November, their report did not say any problem with my filter, nor did they mention changing filter every month. I have followed their original suggestion to change filter every three months, which is also the suggestion of filter vendor.

They then sent me a $162 bill for A/C service. When I said I cannot pay the bill because I did not ask you to do A/C service and our A/C does not have a problem based on your report, their manager replied by saying "Its AC season, so everything says AC service." He went further to say that they would not honor their warranty contract.

Following the response from Stan to my above post, I contacted the owner as he suggested. He did not provide any new solution except repeating the same things the manager had said. I am very disappointed.
