What is a variable frequency drive and how does it help my system?

A VFD controls motor speed in HVAC fans and pumps, reducing energy use and wear. It helps commercial and multi-unit systems run more efficiently and last longer.

Do you install VFDs on commercial rooftop units and air handlers?

Yes. We install and service VFDs on commercial rooftop units, air handlers, and other HVAC equipment for property managers and light commercial facilities in San Jose.

How do I know if my system could benefit from a VFD?

If your commercial HVAC system runs at constant speed, you are likely wasting energy. Our technicians assess your system and recommend VFDs only when they provide real value.

Are VFD installations covered by a warranty?

Yes. All VFD installation and service labor is backed by our 1-year labor warranty, and manufacturer equipment warranties apply to all components we install.

Do you offer financing for VFD installation projects?

Yes. Hearth Financing is available for qualifying projects. You can check eligibility with no initial impact on your credit score.
