Commercial Condensing Unit Repair & Replacement

The condensing unit is where refrigeration and HVAC systems reject heat, and it is where most of the hard-working components live: the compressor, condenser coil, fan motors and controls. We repair and replace condensing units serving walk-in coolers and freezers, display cases, reach-in systems, split system air conditioners and process cooling.

Rooftop and outdoor condensing units in the East Bay deal with sun, salt air near the bay, kitchen grease and debris. Keeping them clean and correctly charged is the biggest factor in their service life.

Diagnostics

Common failures and what they mean

Fault 01

High head pressure trips in the afternoon

Dirty coils, failed fans or units installed too close to walls or each other.

Fault 02

Compressor burnout

A burnout requires proper system clean-up, new driers and root-cause correction or the replacement compressor will fail too.

Fault 03

Unit will not start in cold weather

Low ambient issues and head pressure controls; common on outdoor refrigeration units in winter.

Fault 04

Oil spots or hissing at the unit

Active refrigerant leak. Find and repair it rather than repeatedly recharging.
