Beyond Standard HVAC Service
Certified Technicians for Systems That Need Specialized Expertise
A VRF system throwing error codes needs a technician who understands refrigerant charge balancing across branch circuits, not someone who only works on rooftop units. A compressed air system losing pressure needs someone who can diagnose the compressor, the dryer, the piping, and the point-of-use regulators as an integrated system. Gas piping requires licensed work with proper leak detection and pressure testing protocols.
These are not systems you hand to a general service technician and hope for the best. Our specialty systems technicians carry manufacturer-specific training, relevant certifications, and diagnostic tools purpose-built for the systems they service. And because Dual Temp also designs and installs these systems through our construction division, our service technicians have access to institutional knowledge about how these systems are built, not just how they are supposed to run.
