Commercial Boiler Service in Philadelphia
Most commercial HVAC contractors avoid boiler work. Custom Aire has been diagnosing steam traps, replacing heat exchangers, and maintaining hydronic systems across Philadelphia for 57 years.
Repair, Maintain, or Replace Your Commercial Boiler in Philadelphia
Custom Aire handles commercial boiler repair, maintenance, and replacement across the full range of systems running in Philadelphia-area buildings. That means cast-iron steam boilers in pre-war office buildings, fire-tube and water-tube hot water systems in healthcare and warehouse facilities, and modern high-efficiency condensing units in newer construction. Our NATE-certified technicians carry credentials on every major boiler configuration, so one team handles the full scope of your boiler work, from installation to repairs, regardless of what’s in the mechanical room.
Built-In Fabrication for Custom Piping and Fittings
Boiler work almost always involves custom metalwork, and most contractors sub that out. Custom Aire’s in-house sheet metal shop fabricates piping, fittings, and ductwork components on-site, which cuts lead time and keeps your project under one team from start to finish.
Keep Your Building's Heat Running Without the Guesswork
Whether your building needs an emergency boiler repair, a pre-season inspection, or a full system replacement quote, our commercial team will coordinate around your facility’s operating hours.
Solve Boiler Problems at Every Stage of the Equipment Lifecycle
Commercial boilers don’t fail all at once. They lose efficiency, develop intermittent faults, and eventually hit a point where repair costs outpace replacement value. Our team works with facility managers at every stage to ensure your boiler is always performing at its best.
Diagnose and Repair Pressure, Ignition, and Control Failures
Pressure drops, short-cycling, ignition lockouts, leaking relief valves, circulator pump failures, and control board malfunctions. Our technicians carry diagnostic equipment and common commercial boiler parts on every truck, and every repair is backed by our 1-year no-breakdown guarantee.
Maintain Performance and Protect Your Warranty
Annual commercial boiler maintenance includes combustion analysis, heat exchanger inspection, safety control testing, and water-side checks. PMA clients receive scheduled visits coordinated around your facility’s hours, priority emergency response, and no overtime fees on after-hours calls.
Size and Install the Right Replacement
When repair no longer makes financial sense, we’ll assess your building’s heating load and spec a properly sized replacement. Modern condensing boilers operate at 90%+ efficiency compared to the 80% or lower output of older atmospheric units, and qualifying systems may be eligible for utility rebates.
Frequently Asked Questions
We have a steam system in an older building. Can you convert it to hot water?
It depends on the building. Steam-to-hot-water conversions involve re-piping, new radiation, and potentially structural changes, so they’re not always practical or cost-effective. In many older Philadelphia buildings, the smarter path for commercial boiler service is maintaining and upgrading the existing steam system. We’ll evaluate your building and give you an honest recommendation about which system works best either way.
Do you handle boiler work for multi-building properties?
Yes. We service commercial boilers up to 25 tons and regularly work across multi-building campuses for offices, healthcare, and warehousing. Our PMAs can be scoped across multiple buildings under a single agreement.
How quickly can you respond to a boiler emergency?
We dispatch on-call technicians 24/7/365 for commercial boiler emergencies. PMA clients receive priority scheduling and pay no overtime fees on after-hours or weekend calls.
Our boiler is 30 years old but still running. How do we know when it's time to replace?
Age alone doesn’t decide it. The real indicators are rising repair frequency, declining efficiency (visible in your fuel bills year over year), and parts availability. If your technician is sourcing parts from salvage or the unit is running below 80% combustion efficiency, replacement typically saves money within a few heating seasons. We’ll run the numbers with you and give you a straight comparison.
