Heating repair & installation
Heating Services Built for Philly Winters
Furnaces, boilers, heat pumps, and everything in between — repaired, replaced, and maintained by the crew Philadelphia calls when the heat goes out.
Every system, every brand
When your heat goes out, hours matter. We treat it that way.
A dead heating system in January isn't an inconvenience — it's an emergency for your family, your pipes, and your home. AJM Mechanical has spent 19+ years repairing and replacing heating systems across Greater Philadelphia and Southern New Jersey, and the playbook hasn't changed: show up fast, diagnose honestly, and fix what actually needs fixing.
We service gas furnaces, oil systems, boilers, heat pumps, and ductless heating across every major brand. Whether your rowhome runs on a decades-old boiler or your new build has a high-efficiency heat pump, the person who shows up has seen your system before — and carries the parts that most commonly fail.
No commission-driven upsells, no scare tactics. If a $200 repair buys your system another five winters, that's what we'll tell you. When replacement genuinely makes sense, you'll get straight numbers and options at more than one price point.
What's included
Full-service heating, one call
Fast diagnosis and same-day repair for furnaces, boilers, and heat pumps of every major brand.
Right-sized replacement systems with clear, upfront quotes — never a one-size-fits-all box.
24/7 response when the heat dies — because Philly winters don't wait for business hours.
Pre-winter inspections that catch cracked heat exchangers, weak igniters, and failing motors early.
Smart thermostat installation and zoning controls that cut bills without cutting comfort.
Carbon monoxide testing, gas-line checks, and venting inspections with every service call.
Know the warning signs
Six signs your heating system is asking for help
Uneven heat usually means airflow, zoning, or a system losing capacity — not a thermostat problem.
A system that starts and stops constantly is overworking itself toward an early failure.
A tired system burns more to deliver less. Efficiency loss shows up on the bill first.
New noises are mechanical wear announcing itself. Caught early, it's a part — not a system.
A healthy gas flame burns blue. Yellow can signal incomplete combustion — a carbon monoxide risk.
Past 15 years, every repair decision should be weighed against replacement economics. We'll show you the math.

Common questions
Heating Services FAQs
Do you charge extra for same-day heating repair?
No. Same-day is our standard response, not a premium service. Emergency after-hours calls are quoted upfront before anyone rolls a truck.
Repair or replace — how do you decide?
We weigh the repair cost against the system's age, efficiency, and likely remaining life. If the repair is more than a third of replacement cost on an old system, we'll show you both numbers and let you decide.
Which brands do you service?
All major residential brands — gas furnaces, boilers, heat pumps, and ductless. If it heats a home in the Philadelphia area, we've worked on it.
How fast can you install a new heating system?
In most cases, next-day installation after the estimate — and same-day when the schedule allows. No-heat replacements in winter get priority.
