Commercial Rooftop HVAC service was completed in Redwood City, California for a commercial property with two rooftop units experiencing performance issues. One unit had mechanical wear, while the second showed reduced cooling due to low refrigerant levels.
Unit 1 — Carrier 48TCDD12A2A5A0A0A0
Required mechanical repairs. Work included replacement of crankcase heater #1 and #2, installation of a new drive belt, inspection of belt alignment, and verification of compressor protection and startup cycle.
Failed crankcase heaters can cause refrigerant migration into the compressor during off cycles, increasing risk of damage.
Unit 2 — Day & Night PHN330000K000A1
Was serviced for refrigerant loss. Work included refrigerant recharge, pressure and temperature checks, leak inspection, adjustment of refrigerant charge, and verification of cooling performance after service.
Both systems were restored to proper operation. Even small issues such as refrigerant imbalance or worn components can gradually lead to reduced efficiency and costly breakdowns if not addressed in time.
Regular HVAC maintenance is recommended to maintain stable performance, improve energy efficiency, and extend equipment lifespan in commercial building.
