Commercial HVAC in Langhorne, PA

Commercial HVAC in Langhorne — keep your business open and comfortable.

Commercial HVAC in Langhorne is judged by a different standard than residential work: whether your doors stayed open. A restaurant with a dead rooftop unit on a Friday night, an office that can't hold temperature, a warehouse with a boiler down in January — those aren't comfort complaints, they're operational problems with a cost attached to every hour.

JR Michalski has served Bucks County businesses since 1990. We install, repair, and maintain commercial heating and cooling systems of every make and model — rooftop units, split systems, furnaces, boilers, and heat pumps — and our own sheet metal shop fabricates the ductwork, so custom fittings and change-outs don't sit waiting on an outside supplier.

What we do for businesses

Installation, repair, and preventive maintenance.

One contractor for the whole mechanical scope — including the ductwork, fabricated in our own shop. Not sure what your building needs? Call and we'll walk the property with you.

Service 01

Commercial Installation & Replacement

New systems, unit change-outs, and build-outs — sized from an actual load calculation rather than a rule of thumb, then installed with the ductwork fabricated to fit your building. Free estimates.

Service 02

Commercial Repair

Rooftop units, split systems, furnaces, boilers, heat pumps, and controls — all makes and models. We diagnose the root cause with proper test equipment instead of resetting it and hoping.

Service 03

Preventive Maintenance Agreements

Scheduled service built around your equipment list and run hours. Commercial systems run far more hours than residential — twice-yearly service is the realistic baseline for most buildings.

Common questions

Commercial HVAC questions business owners ask us most.

Quick answers on commercial service, maintenance agreements, and how we work around your operating hours.

Call 215-752-1442
How often should commercial HVAC be serviced?
Twice a year is the realistic baseline for most commercial buildings — once before cooling season and once before heating season. Commercial equipment accumulates far more run hours than residential, and buildings with heavy use, kitchen exhaust, or dusty conditions often need quarterly attention.
Do you offer commercial maintenance agreements?
Yes. We build the agreement around your actual equipment list and run hours rather than selling a fixed package — scheduled visits, priority response, and a written condition report after each service so you have documentation for ownership or a warranty claim.
Can you work outside our business hours?
Yes, and for retail, restaurant, and office clients that's usually the default. We schedule installations and major service for nights, weekends, or phased by zone, and we'll tell you up front which portions of the work genuinely require the system to be down.
Do you service equipment you didn't install?
Yes — all makes, models, and brands. Taking over service for an existing building is common, and we'll give you an honest condition assessment of what's on the roof, including which units have real life left and which are living on borrowed time.
Do you fabricate your own ductwork?
We do. Our in-house sheet metal shop fabricates ductwork, fittings, and transitions to the dimensions of the job. It keeps custom pieces off an outside supplier's lead time, which matters most on retrofits and change-outs where nothing is ever quite standard.
Do you serve Philadelphia and the surrounding area?
Yes. We're based in Langhorne and serve commercial properties throughout Bucks County and Montgomery County, into Philadelphia, and across the surrounding NJ/PA area — including Trenton, Burlington, Ewing, and the Route 1 corridor. Call us and we'll confirm we cover your address.
How much does commercial HVAC work cost?
It depends on tonnage, equipment selection, roof and structural conditions, the ductwork and fabrication scope, and access — which is why we walk the property before quoting. You get a written scope and price to approve before anything proceeds, and replacements come with a free estimate.
