How Pennsylvania homes are heated

Pennsylvania heats with a wider spread of fuels than most states. Utility gas leads with 1,942,752 of 3,656,971 owner-occupied homes (53.1%) in table B25117 of the 2020-2024 ACS, but fuel oil and kerosene heat 624,291 owner homes, 17.1%, the ninth highest share in the country. Wood and coal together still heat about 140,000 owner homes.

Solar, other fuels and no fuel44,9791.2%ACS 2020-2024, B25117

Across every occupied home, owners and renters together, the B25040 table (2020-2024 ACS) gives utility gas 51.3% and electricity 25.3% of 5,274,853 units. Fuel type tells an HVAC buyer what is in the basement: an oil boiler or oil furnace needs a different technician and different replacement options than a gas furnace or a heat pump. The table describes installed heating, not the number of leads tied to any fuel.

Propane and electricity fill most of the remaining gap. Tank gas heats 218,283 owner homes (6.0%) and electricity 686,474 (18.8%) in the same B25117 estimates (2020-2024 ACS). At 18.8%, the electric share ranks 30th of the 50 states, so a buyer focused on heat pumps would mostly be quoting homes that heat with another fuel today.

Heating and cooling demand in Pennsylvania by degree days

Pennsylvania’s climate is heating-led. The NCEI statewide heating degree day series records 5,729 for 2025, just above the 1991-2020 average of 5,701, which places the state 21st of the 48 with a series.

Cooling is about one seventh of that. The cooling degree day series shows 787 for 2025 against a 1991-2020 average of 706, so summers in 2025 ran warmer than the long-term pattern, while heating stays the larger share of the workload.

How these are calculated: each day contributes the number of degrees its mean temperature sits below 65°F (heating) or above it (cooling). NCEI adds those up for January through December statewide, and the average here is the mean of the yearly totals for 1991 to 2020.

Pennsylvania HVAC contractor rules

This section is general information, not legal advice. It summarizes official sources as of October 8, 2026; check the current text of each rule before relying on it.

Pennsylvania’s statewide rule for home improvement contractors, and the agency that administers it, are described with their official source on leads in Pennsylvania, so this page does not restate them. A buyer that places requests with Pennsylvania HVAC contractors can read that summary before taking on a new contractor client.

One federal requirement applies everywhere: technicians who service or dispose of equipment containing refrigerant must hold certification under EPA Section 608. It applies to heat pumps and central air conditioners whatever fuel the home uses for heat.

Pennsylvania owners and renters in HVAC terms

In the 2020-2024 ACS table B25003, Pennsylvania has 3,656,971 owner-occupied homes and 1,617,882 renter households, 5,274,853 occupied units in all. Owners hold about 69% of households, and they are the ones who decide on a boiler, furnace or heat pump replacement; tenants depend on the landlord for the same decision.

Housing age and Pennsylvania’s energy code are on Pennsylvania window replacement leads, and this page does not repeat them.

Pennsylvania counties by owner-occupied homes

Fuel oil matters too much in Pennsylvania to leave out, so this table shows utility gas and fuel oil shares for the ten counties with the most owner-occupied homes, from the ACS 5-year 2020-2024 county tables B25003 and B25117. The figures describe housing only and say nothing about lead counts.

Berks116,33442.8%26.3%ACS 2020-2024, B25003 and B25117 (county)

The two big cities are gas markets, Allegheny at 90.0% and Philadelphia at 80.2%, while the counties around Philadelphia and in the southeast lean on oil: Bucks at 27.4% and Berks at 26.3%, per the county data (2020-2024 ACS). Chester also stands out for propane, at 14.2% of owner homes, and Lancaster for electricity, at 29.4%.

West of the Susquehanna the pattern changes again. Westmoreland, next to Pittsburgh, is 68.5% gas with 13.5% oil, and Delaware County, southwest of Philadelphia, is 65.6% gas with 16.4% oil in the same ACS county estimates (2020-2024 ACS). Every county in the table has at least some oil heat, from 1.2% in Allegheny upward, so oil equipment turns up in every one of these counties, not only in the southeast.

Reading the Pennsylvania numbers for an HVAC plan

Three points come out of the fuel, county and climate figures:

  • Oil heat is a large segment. With 624,291 owner homes on fuel oil or kerosene in table B25117 (2020-2024 ACS), a buyer with oil burner technicians has a large installed base to serve, and one that converts oil systems to other fuels can find those homes concentrated in a few counties.
  • The fuel map splits east and west. Pittsburgh’s Allegheny County is 90.0% gas, while Bucks, Berks and Chester are each above 20% oil in the county table (2020-2024 ACS). One statewide approach would fit neither end.
  • Heating sets the calendar. The 5,729 heating degree days in 2025 from the NCEI heating series are more than seven times the 787 cooling degree days.

None of these points describes lead counts or demand; they read official housing and climate data.

What Pennsylvania HVAC buyers filter on

Pennsylvania HVAC buyers have the same filterFilterA rule that decides which leads a buyer is offered, based on fields such as vertical, sub-type, state, ZIP code, homeownership or accident details. Glossary set as other home services buyers, and the data above gives each one a purpose here:

  • Project type: for example install, replace or repair, for heating or cooling, including fuel conversions in oil-heated areas.
  • Homeowner status: the 3,656,971 owners counted above make replacement decisions (ACS 2020-2024, B25117).
  • Timeframe: a failed boiler in winter is urgent; a planned conversion can wait for the off-season.
  • ZIP code: lets an oil specialist stay in the southeastern counties and a gas specialist stay in Allegheny or Philadelphia.

When HVAC opens, Pennsylvania buyers will set these filters per campaign, down to the ZIP code, as on Summit’s other home services leads. Once HVAC opens, HVAC leads will be exclusive by default, with shared delivery on request. The sample HVAC lead lists the fields.

Where buyers filter in Pennsylvania

Philadelphia’s metro area spills into New Jersey, Delaware and Maryland, and Allentown’s into New Jersey, so both figures below are whole-metro counts from the Census Bureau’s July 1, 2025 estimates. Pennsylvania HVAC companies generally plan service areas around one of these metros. Once HVAC opens, buyers will be able to set coverage on any ZIP code, inside these areas or outside them.

  • Philadelphia-Camden-Wilmington, PA-NJ-DE-MD: 6,329,118 (July 1, 2025 estimate, whole metro area)
  • Pittsburgh: 2,421,992 (July 1, 2025 estimate)
  • Allentown-Bethlehem-Easton, PA-NJ: 887,615 (July 1, 2025 estimate, whole metro area)
  • Harrisburg-Carlisle: 617,427 (July 1, 2025 estimate)
  • Scranton--Wilkes-Barre: 574,418 (July 1, 2025 estimate)
  • Lancaster: 563,159 (July 1, 2025 estimate)

Pennsylvania HVAC lead questions

How many Pennsylvania owner-occupied homes heat with fuel oil?

624,291, or 17.1% of 3,656,971 owner-occupied homes, in the Census Bureau’s ACS 5-year estimates for 2020-2024 (table B25117). Only eight states have a higher fuel oil share.

Which Pennsylvania counties have the largest share of owner homes on fuel oil?

Among the ten counties with the most owner-occupied homes, Bucks (27.4%) and Berks (26.3%), followed by Chester (20.9%), in ACS 5-year 2020-2024 county data (table B25117).

How many heating degree days did Pennsylvania record in 2025?

5,729, against a 1991-2020 average of 5,701, in NOAA NCEI’s Climate at a Glance statewide series. Cooling degree days were 787 the same year.

Do Pennsylvania HVAC technicians need refrigerant certification?

Federal rules under EPA Section 608 require certification for technicians who service or dispose of equipment containing refrigerant, in Pennsylvania as in every state. This is general information, not legal advice.

Can a buyer narrow Pennsylvania HVAC coverage to particular ZIP codes?

Not yet: HVAC is now onboarding. When it opens, buyers will set filters down to the ZIP code, as on Summit’s other home services leads, and leads will be exclusive by default.
