Chester Housing Stock
Half the homes in Chester were built before 1947 (Census ACS median), so the typical house is about 79 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. About 5,100 households here own their home, 40.9% of the occupied total. With a median household income of $39,809 and a median home value of $85,400, local labor rates come out below the national middle in our model.
Delaware County had 5 hail days and 36 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.5 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

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
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Maintenance plans often put members first in line for emergency calls.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
