Greencastle is the town the Heat Cool and Happy website names first, and it sits right in the middle of the company’s tri-state territory: Hagerstown is a short drive south on I-81, Chambersburg a short drive north.
The borough itself has a historic center of brick and frame homes around the square. Out in Antrim Township, farmland and older farmhouses sit beside newer subdivisions that went up as the I-81 corridor grew. That mix means one week is an oil furnace in a stone farmhouse and the next is a heat pump changeout in a house that’s fifteen years old.

What’s different in Greencastle
Know the house before the system.
Out past the gas lines
Many homes outside the borough don’t have natural gas, so heat pumps, oil and propane are the usual choices. A modern heat pump with a backup can replace an oil furnace and a separate A/C with one system.
Newer houses, first replacements
Builder-grade systems in subdivisions from the 2000s and 2010s are reaching the 12 to 15 year range where replacement starts to make more sense than repair.
Pennsylvania rules
Pennsylvania has no statewide HVAC license. Home improvement contractors register with the PA Attorney General’s office, and permits run through the township or borough’s code office.

We heat with oil. Is a heat pump worth it in Greencastle?
It can be. A heat pump handles most of the winter efficiently and cools in summer too; on the coldest nights a backup source can help. Whether it pays off depends on the house, the ductwork and your oil use, which is what the evaluation is for.
Our house is about 15 years old. Repair or replace?
At 12 to 15 years, it’s worth getting an honest look. Repairs more than once a year, climbing bills, uneven rooms or new noises usually point toward replacement. If it’s an R-22 system, replacement is usually more practical than repair.
