Your written scope for a heating or air-conditioning job in Philadelphia

Philadelphia's Franklin Institute station has a 1991–2020 normal of 4,211.8 heating degree days annually; for a furnace repair scope, pair that heating-season context with a description of the fault and a specified heating-operation test. Source: NOAA station normals; read 2026-10-17.

The equipment: capacity, efficiency rating and model, in writing
The heating side too: Philadelphia's heating degree days mean the system heats as well as cools
Gas line and venting checks if the system burns gas, as many of Philadelphia's homes do
Whether your job is the kind Philadelphia's rule quoted below exempts or the kind it says needs a permit (heating, venting, and air conditioning)
Removal and disposal of the old parts or materials
Warranty terms on parts and labor, in writing

AC repair Philadelphia

At Philadelphia's Franklin Institute station, the 1991–2020 normal is 1,603.1 cooling degree days annually; for an AC repair scope, identify the cooling fault and whether the quoted work includes an operating test, while treating the station normal as climate context rather than a measurement of the home. Source: NOAA station normals; read 2026-10-17.

Ask which heat source the quoted equipment will use.

NOAA explains: “The degree day is one measure of the weather related energy demand.” Ask for equipment sized to that climate.

Median hourly wage for Heating, Air Conditioning, and Refrigeration Mechanics and Installers in the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD area, May 2025: $31.05 (U.S. Bureau of Labor Statistics, Occupational Employment and Wage Statistics).

This is what workers in this occupation are paid per hour. It is not what a contractor charges for a job.

How does InstaBids work?

InstaBids does not hold payment for the work; you pay the contractor directly on the terms of the bid you accepted.

How is InstaBids different?

Each bidder appears under a stable label such as Contractor A, so you judge the work, not the brand.

Contact details stay hidden until the homeowner picks a contractor and they confirm the connection.
