Your VRF system is probably in trouble. Here's why.
Manhattan's commercial VRF boom ran from 2012 through 2017. That means thousands of systems across the city are now eight to twelve years old — the window where compressors start failing, inverter boards give out, refrigerant joints fatigue, and rooftop condensers corrode. VRF compressors run in both heating and cooling modes, which wears them out faster than conventional equipment.
The failures are not random. They are scheduled. The only question is whether your building finds out during a planned assessment or during a tenant complaint.

When landmark properties and new-construction luxury towers need VRF work done right, they call Mountain Mechanical. Three decades of commercial mechanical expertise, factory certifications on every major brand, and an owner on every project mean your building's VRF system is in hands that have seen the hard failures before.
From pre-commissioning and critical systems testing to full assessment and corrective measures aligned with manufacturer guidelines, we deliver the level of service these landmark properties require.

“The problem exists across all brands because technicians were not properly trained in the correct architecture and installation protocols. VRF hit the scene so fast that technicians were not prepared. That's where we come in.”
