Allentown Housing Stock
Half the homes in Allentown were built before 1951 (Census ACS median), so the typical house is about 75 years old. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 42.3% of occupied homes, roughly 19,000 households. Homes here have a median value of $188,900 and households a median income of $53,403. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Lehigh County show 10 hail days and 40 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.25 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Lehigh County also had 2 tornado days in that period.

Pennsylvania Licensing and Efficiency Rules
Pennsylvania falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Pennsylvania the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask what the emergency fee is before the truck is sent.
- Maintenance plans often put members first in line for emergency calls.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
