“Don’t know the names of the two service people but they were very competent and respectful. Made some thermostat adjustments which hopefully will improve the expense of enduring sustained bitter cold weather. Asked them if there is a way to manually adjust humidifier settings in bitter cold weather and in investigating they discovered that no such equipment had been installed when the heat pump system was purchased in 2023 and that the humidifier had not been working at all for that reason. After consultation with the office they installed the humidity monitoring and adjustment equipment.”
“We are getting the washer & dryer replaced next week. We had Federick come out to check out the hoses leading to the washer. They’d been in place for 22 years. We couldn’t get them off.
Dennis checked it out. Explained what needed to be done. Got it done quickly. And it is a simpler arrangement than before.
We really appreciated his efficient work. Especially like having things explained before and after.
Dennis also gave us some recommendations on faucet brands to check out as next on our list is to replace the kitchen sink faucet.
We’ll be in touch with Frederick soon…”
