Duncannon Heating and Cooling for Older Homes

Someone should be available if we need access to a basement, crawl space, thermostat or indoor equipment. If the outdoor unit is the only accessible equipment, tell us what areas we can enter. We still need accurate equipment information and a clear description of the problem before we begin.

Duncannon sits near the Susquehanna River, and Shermans Creek joins the river just downstream. Moisture does not identify a specific failure, but it makes condensate drainage, coil condition, electrical connections and corrosion worth checking. We inspect those areas when the symptom or equipment location calls for it.

The schedule depends on the existing furnace, access, duct connections, fuel arrangement and required inspection steps. Older Duncannon homes can have tight basements or unusual duct paths. We review the equipment and installation conditions first, then explain the expected work sequence before starting.

We check exposed seams, disconnected sections, crushed runs, return airflow and the connection between the furnace and supply ducts. We also look at basement or crawl space access. Since 55.5% of Perry County homes were built before 1980, older duct layouts are an important part of replacement planning.

The existing fuel, furnace size, duct condition, access, venting and electrical controls all affect the work. Permit and inspection requirements also matter. Duncannon Borough uses Building Inspection Underwriters, Inc. through Perry COG, so we include the local code process when it applies.

The thermostat signal may be present while ignition, flame sensing, airflow or a safety control stops heating. A blower problem or restricted duct path can also affect delivered heat. We inspect the sequence, safety controls and airflow rather than assuming the furnace needs replacement.
