“Saturday before snow storm, 5:30am no heat. Emergency fee $125 for the Carrier system installed by Jos Frederick less than 3 yrs old. Service came out at 11, worked until 2, large bumble bee in 4×2 in plastic container, water in part of furnace where working. Said this should have been maintained, showed slip of maintenance 9/25. He said not all companies do as thorough a maintenance as Jos Frederick. He cleaned out container, said gaskets need replaced. Had to order. Wanted customer to pay additional $187 for his time. Spoke to Operation Mgr, John, said no additional cut as tech did not put in writing. System was working. Less than one week later, again 5:30 am not working. Sent different tech. Worked a few hours, replaced original 4×2 plastic container, flimsy gaskets, was running, water all soaked up from mess on floor, said good to go. 13 days later, 5:30am no heat. 4/16. Came out at 10 am said $189 for his labor to replace Pressure Switch. Not covered with warranty. Do not understand why the customer should pay for labor to replace a “defective” part from Carrier HVAC. I spent over $12,000 on that system and had it maintained 9/25 but still had problem. Tried to reason with Operation Mgr, John, but he said he had to run a business and I could get it replaced by another company. Told him to order part and install. Installed part for $189 today but wrote on invoice Not pleased with service costs and this was not over. Used Jos Frederick because my neighbor was a sister of the owner and felt they would be responsible, trustworthy, not the most reasonable price, dependable. I’m writing this Poor review as that was not the case and I do Not Recommend Jos Frederick for any HVAC system. Also, tech recommended to have duct work cleaned and dryer vent, which they also Do Not Do! Had to schedule another HVAC to do that next month!”

“Woke up on Saturday before snow storm with no heat. Sent repairman who worked from 11-2 to get system running but said the Carrier Dystem had a “defective” part hand had to be ordered and replaced. Asked to inform Carrier, as it was less than 3 years old and they needed to stand by defective products. Always used Carrier for systems, they need to be made aware they are selling defective parts and they should replace for No Charge, including labor. John did that! TU”

“On 2/24/26 Repairman Eusebio M. arrived to diagnose and repair our gas furnace. He was very professional and knowledgeable. In just a short time he had found and fixed the problem on our heater. Very satisfied and happy with the service.”

“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…”
