              The furnace was not a 2022 furnace like I had been promised. The furnace I received had a July 2021 was the manufacture date. It also says its compatible for mobile homes. I questioned it because it did not look like the model I had seen in the advertisement. This caused me to investigate more and so I got the contract out and it said that my furnace was supposed to be made in 2022. It seems like its odd that they would bring out this July 2021 furnace when my contract says I would be receiving a 2022.

              *************** One-Hour recently installed a new hot water boiler for us. As to be expected in a 100+ yr old house a few problems came up but they were handled promptly and efficiently. They always showed up with sufficient workers for the job whether to transport a ********************************************************************** the chimney. Several other companies we contacted said we would be responsible for getting the flue liner. Although there was some delay in finding a replacement part, they always responded promptly and did their best to complete the job. Their customer representative *** and HVAC technician ******* were especially helpful in resolving any issues that occurred at the last minute.
