Arrived onsite to investigate concerns about propane usage for the heating system. The customer felt the system was running constantly and consuming an excessive amount of propane. They reported using approximately 250 gallons over the past month, which is reasonable given the time of year and the size of the home. We inspected the heating system and noted that some of the thermostats are older and may be inaccurate; otherwise, the system appeared to be operating properly. We emailed estimates to install customer-supplied thermostats, replace a noisy power venter, and add an electrical outlet in the garage.
