Specialty Systems Across Eastern PA
Self-Performed, Which Means No Waiting on a Sub
These systems demand training and certification that general HVAC technicians do not carry: manufacturer VRF credentials, 6G welding certification, licensed gas work. Dual Temp employs those people directly. When a compressor drops the plant or a branch selector box isolates a floor, the technician who arrives is qualified to fix it rather than qualified to diagnose it and schedule someone else.
That matters most on the systems where downtime stops production rather than just affecting comfort. Compressed air, process piping, and critical cooling failures do not wait for a subcontractor’s schedule.
Specialty Systems We Service
Four Disciplines, One Contractor
Each of these has its own page with deeper detail on failure modes and diagnostics.
VRF & Refrigerant Systems
Heat pump and heat recovery VRF from Mitsubishi, Daikin, LG, Samsung, and Fujitsu, including branch selector boxes and communication networks. Repairs follow manufacturer protocol for brazing, evacuation, and charge calculation, which is what keeps warranties intact.
Compressed Air Systems
Rotary screw, reciprocating, and scroll compressors, dryers, filtration, and distribution. We run ultrasonic leak detection across the plant and prioritize repairs by volume lost, since an unmaintained system commonly leaks 20 to 30 percent of its output.
Gas, Process & Specialty Piping
Licensed gas piping work, process piping in manufacturing facilities, and hydronic and steam pipefitting in occupied buildings. Our welders hold 6G certification and every gas scope closes out with pressure testing and documented results.
