Commercial HVAC Repair in Philadelphia, PA

Most commercial HVAC contractors make you leave a message. Custom Aire dispatches a technician.

Stop Waiting on Hold and Get Your Building Fixed

Every hour of downtime costs your facility real money in tenant complaints, lost productivity, or both. For over 57 years and three generations, Custom Aire has been the commercial HVAC repair team Philadelphia facility managers call when the system goes down. NATE-certified technicians, trucks stocked with common commercial parts, and a 1-year no-breakdown guarantee on every job. If the same issue comes back inside 12 months, the labor is on us.

Solve Your Commercial HVAC Problem Before It Gets Worse

The longer a system runs without a fix, the more expensive the repair tends to get. Custom Aire’s commercial repair team is available around the clock, with priority dispatch for maintenance agreement clients.

Fix Every System in Your Building

Commercial buildings run on a mix of equipment ages, brands, and configurations. Custom Aire’s technicians are trained across every system we install and most we didn’t, and most commercial HVAC repair calls are diagnosed and resolved without a return trip.

Solve Rooftop Unit Failures Fast

RTUs are the most common commercial HVAC repair service call our team handles. Compressor issues, control failures, refrigerant leaks, and economizer problems are all diagnosed on the roof, with common parts on the truck to limit return visits.

Restore Heat From Commercial Boilers and Hydronic Systems

Steam, hot water, and high-efficiency boilers in older Philadelphia buildings and newer mechanical rooms. Ignition failures, pressure problems, control diagnostics, and full system troubleshooting across every common configuration in the area.

Repair Split Systems and Ductless Commercial Units

Smaller offices, retail suites, and zone-specific systems often run on split or ductless equipment. Custom Aire diagnoses, repairs, and recommissions these systems with the same urgency as larger rooftop work.

Reach Real Technicians 24/7 for Emergency HVAC Repair

Emergency HVAC repair calls route to a staffed answering service and on-call technicians, not a voicemail box. Maintenance agreement clients pay standard rates around the clock, so an after-hours call doesn’t reset your repair budget for the quarter.

Frequently Asked Questions

What happens when I call after hours for an emergency?

The call goes to a staffed answering service, and an on-call technician is dispatched. Maintenance agreement clients are billed at standard rates, no overtime fees, regardless of when the call comes in. Non-agreement customers pay an after-hours rate, and we’ll always quote before starting work.

What size systems do you work on?

Custom Aire services commercial HVAC up to 25 tons. We don’t work on chillers, cooling towers, or industrial process equipment above that range, which keeps response times tight on the work we specialize in.

How fast can a technician reach my building?

Same-day in most cases, often within a few hours depending on the time and call volume. Agreement clients receive priority dispatch on every call.

How does a maintenance agreement affect repair costs?

Agreement clients receive discounted parts and labor on all repair work, priority dispatch year-round, and no overtime charges on emergency calls. For most facility teams, a single after-hours repair saves a meaningful share of the annual agreement cost.
