Quick Summary
When a rooftop unit fails on a 105°F Central Valley afternoon, every hour of downtime costs you revenue, food spoilage risk, customer comfort, and employee productivity. HVAC Penguin is a Turlock-based, fully licensed and insured commercial HVAC contractor (CSLB #1115847) specializing in light commercial HVAC repair up to 25 tons — rooftop units (RTUs), package units, split systems, and economizer-controlled equipment.
We service restaurants, retail storefronts, medical and dental offices, churches, salons, small warehouses, and multi-tenant properties from Turlock to Modesto, Ceres, Manteca, Patterson, Newman, and across all of Stanislaus and Merced counties. Our commercial trucks roll stocked with the parts behind the majority of light commercial failures — capacitors, contactors, condenser fan motors, control boards, belts, and refrigerant — so most service calls are resolved on the first visit.
After-hours dispatch is available for revenue-critical accounts. Every diagnostic ends with a written, flat-rate estimate before any repair begins — no surprise charges, no hourly creep, and full documentation for property managers and asset records.
Our commercial trucks are stocked with the parts behind the majority of light commercial HVAC failures. Most calls are resolved on the first visit.
#1 commercial AC failure cause. Stocked on every truck — typically replaced same visit.
Pitted or welded contacts that prevent the compressor from engaging.
Seized motors, bad bearings, weak run capacitors. Universal motors stocked.
Stuck open/closed economizers killing efficiency or comfort. Diagnose, free, or replace.
Failed control boards, blown 24V transformers, bad relays — common after lightning or power events.
Cracked, glazed, or shredded belts on belt-drive blowers. Replace and re-tension on the spot.
EPA-certified leak detection and proper R-410A / R-22 / R-454B handling.
Determine repair vs. replace, document for warranty claims, provide temporary cooling options.
Predictable, documented, and respectful of your business operations.
Every category of light commercial HVAC under 25 tons — gas/electric, heat pump, and straight-cool configurations.
The workhorse of light commercial HVAC. We diagnose and repair Carrier, Trane, Lennox, York, Daikin, Rheem, AAON, and Goodman rooftop units — gas/electric, electric/electric, and heat-pump configurations from 3 to 25 tons. Common repairs include compressor diagnosis, contactor and capacitor replacement, condenser fan motors, blower motors, control boards, gas valves, ignitor and flame sensor service, and economizer actuator repair.
Ground-mount and side-discharge package units serving restaurants, churches, and small offices. Same equipment family as RTUs — same diagnostic process, same stocked parts. We also handle dual-fuel package systems where a heat pump pairs with gas backup, common in newer Central Valley commercial construction.
Light commercial splits — outdoor condenser plus indoor air handler or furnace — common in older offices, dental practices, and tenant-improvement build-outs. We service refrigerant leaks, TXV failures, evaporator coil issues, and indoor blower assemblies. EPA Section 608 certified for R-410A, R-22, and R-454B.
Multi-head ductless systems serving salons, professional offices, server closets, and small retail. Communication-board diagnostics, indoor head airflow issues, drain line failures, and refrigerant line set leaks. Mitsubishi, Daikin, LG, and Fujitsu factory-trained service.
Stuck economizer actuators are a leading cause of inflated commercial energy bills and uneven cooling. We diagnose and repair economizer dampers, outdoor air sensors, mixed-air sensors, and zone control systems. Title 24 compliance verification available on request.
Different property types have different stakes. We adjust scheduling, documentation, and parts strategy accordingly.
Honest recommendations grounded in equipment age, repair cost, refrigerant type, and your operating budget.
Whichever way the math points, you'll get a written estimate with the rationale. We'd rather earn your trust now than oversell a replacement you don't need.
Call dispatch — we'll get a tech rolling toward your business.
