W.F. Smith repairs air conditioning on both sides of the Langhorne borough line. Our office confirms the diagnostic fee before a visit, charged whether the repair proceeds or not. It never comes off the bill.
Which half of the ZIP code a house sits in decides most of what follows. A borough house on ductless heads and a township colonial on a ducted split fail in different places. We ask which first.
Mitsubishi Electric is most of what we open in the borough, Lennox most of what we open in the township.
Langhorne Borough is half a square mile of 19th century houses with no duct path, so its cooling arrived as ductless heads. Drainage leads, since a head on a plaster wall sheds condensate through a wall sleeve by gravity.
A sagging or fouled line backs up into the head and down the wall. The rest are head filters, control boards, and line-set fittings behind plaster. Small yards also crowd the outdoor unit.
Middletown subdivisions around the borough run ducted splits, and the tree canopy shortens their lives. Oaks and maples drop seed and leaf into the coil yearly. A packed coil can’t reject heat, so capacity falls before a part does.
Capacitors, contactors, and condenser fan motors follow, and those are the cheap ones. Second-floor complaints are the other standing call, and those are return air, not tonnage.
