Most homes have basements with gas furnaces or boilers, and central AC is common in newer homes. Older homes may have hot-water radiators and limited ductwork, making ductless systems a popular upgrade. For furnace Repair, that means the contractor should start with read the fault code and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: older radiator homes. Homes with radiators need boiler service and often add ductless systems for cooling.
