OverCool LLC

OverCool LLC is a Passaic-based HVAC contractor holding a perfect 5.0-star rating across 48 client reviews. The company serves residential and commercial customers throughout Essex County, including Montclair, Livingston, Millburn, Glen Ridge, and South Orange. Their service menu covers the full spectrum of heating and cooling needs, from new AC and heating system installations to repairs, maintenance, and mini split setups.

What distinguishes OverCool from neighboring contractors is their work with Airfidelity MESP whole-building filtration systems, which they installed across an entire structure in just two days according to one commercial client. The company processed an energy rebate for that customer while delivering additional efficiency upgrades. Their commercial HVAC division handles businesses of varying scales, while residential clients benefit from the same methodical approach to diagnostics and repair.

Reviewers consistently name the technicians who solved their problems. Jacob handled scheduling for a stressed homeowner with a 30-year-old cooling unit, getting them on the calendar quickly and sending advance arrival notice. Technician Abe arrived on time, diagnosed the issue, got the aging system running again, and stayed to monitor performance. He explained the cost-benefit of repairs versus replacement without pressure. Another commercial client praised the team for recommending a repair over a costly new unit installation, demonstrating skill and integrity over profit.
