HVAC Commercial Installation Services

When your facility needs a new commercial HVAC system, Custom Aire’s installation crew delivers the work right the first time, backed by a 10-year parts and labor warranty.

Install Commercial HVAC Systems That Perform for Years

A commercial HVAC installation is a capital decision that shapes your operating costs, tenant comfort, and maintenance budget for the next decade. Custom Aire has completed commercial HVAC system installations across Philadelphia, Bucks County, and Montgomery County for 57 years, and every install is backed by a 10-year parts and labor warranty. Every project comes with NATE-certified crews, in-house ductwork fabrication, and a single accountable team from proposal through commissioning. That’s the standard on every job, not the upgrade.

Demand More From Your Install Partner

Scope drift, equipment delays, and change orders after the contract is signed are the most common complaints facility teams have about commercial HVAC contractors. Custom Aire has operated the same way for 57 years: clear scopes, honest timelines, and pricing that doesn’t move after the contract is signed.

Fabricate Custom Ductwork In-House

Custom Aire’s sheet metal shop handles complex commercial duct runs without relying on a subcontractor’s timeline. That control means tighter installs, fewer delays, and one team accountable for the finished product.

Keep Your Facility Running During the Install

Shutting down for an install isn’t realistic for most buildings. Our crews schedule rooftop replacements, retrofits, and equipment swaps around your hours, including evenings and weekends, and phase the work so critical zones stay online.

Build the Right Commercial HVAC Plan for Your Facility

Tell our commercial team about your building and we’ll schedule a site visit to assess your equipment and put together a written proposal with clear scope and honest pricing. No template quotes, no follow-up pressure.

Frequently Asked Questions

How disruptive is a commercial HVAC installation to our daily operations?

Less than most facility teams expect. Install crews work around your operating hours, phase equipment swaps when possible, and keep disruption limited to the zone being worked on. For most rooftop and split-system replacements, the rest of your building runs normally.

Do you handle new construction projects?

Yes. Custom Aire works with general contractors, builders, and developers on plan-and-spec commercial HVAC installation across Philadelphia, Bucks, and Montgomery Counties, from rough-in through final commissioning.

What's the largest commercial system you'll install?

Commercial HVAC systems up to 25 tons. Custom Aire doesn’t take on chillers, cooling towers, or industrial process equipment above that range, which keeps us focused on the work we do best.
