🌆 Package Unit Repair in Orange County – Residential & Commercial Rooftop HVAC

When a rooftop HVAC unit fails—whether on a home or a commercial building—you need fast diagnosis and a fix that lasts. GoTech Air Conditioning & Heating provides reliable package unit repair across Orange County. We service rooftop package units (RTUs) and ground-mounted packaged systems for all major brands, restoring safe, efficient heating and cooling with clear, upfront options.

Packaged/rooftop systems place all major components in a single outdoor cabinet (compressor, coils, blower). They’re common on roofs or pads and can include electric heat, a gas furnace section, or a heat-pump circuit.

Signs You Need Package Unit or RTU Repair

• Unit won’t start, short-cycles, or runs constantly

• Uneven temperatures, weak airflow, or hot/cold spots

• Loud banging, grinding, buzzing, or fan squeal

• Outdoor coil frosting/icing, water leaks, or tripped float switch

• Thermostat or building controls not responding

• Energy bills rising with no comfort gain

Many of these symptoms come from basic problems. These include dirty coils or filters, wrong refrigerant charge, airflow blockages, or control faults. The DOE and ENERGY STAR identify these as common issues that can be fixed with proper service.

What Our Package Unit Repair Includes

We don’t guess—we test. Every visit uses a structured workflow aligned with industry best practices:

1. Safety & Controls – verify calls for heat/cool, safeties, and cycles

2. Airflow – filter condition, blower/belt, static pressure, duct leaks

3. Refrigerant Circuit – leak check; verify charge via superheat/subcool

4. Electrical – capacitors, contactors/relays, wiring, motor amperage

5. Heat Section – gas ignition, flame sensor, draft/venting (if gas RTU)

6. Economizer/Outside Air (commercial) – damper actuation & logic

7. Performance Verify – temperature split/heat rise, cycle test, trend review

8. Walkthrough – findings, options, prevention, and warranty notes

ENERGY STAR’s maintenance checklist mirrors this approach (thermostat verification, electrical testing/tightening, coil and drain service, airflow checks).

Common Package & RTU Problems We Fix

• Refrigerant leaks / incorrect charge (poor capacity, icing, high bills)

• Coil & drain issues (dirty coils, clogged condensate causing shutdown or leaks)

• Blower/fan failures (belts, bearings, motors, VFDs)

• Ignition & flame sensing faults on gas sections (no light, nuisance lockouts)

• Control board/thermostat faults (erratic staging, no economizer enable)

• Economizer failures (stuck dampers, bad actuators/wiring) that waste energy and ruin comfort—proper economizer maintenance is essential. PNNL

For commercial buildings, advanced rooftop controls and AFDD (automated fault detection & diagnostics) can cut RTU energy use dramatically and surface hidden problems (economizer, airflow, refrigerant, sensors).

Emergency Rooftop Unit Repair — Same-Day Options

Heat waves and cold snaps don’t wait. We offer same-day RTU repair in many Orange County areas, stocked vans for first-visit fixes, and transparent pricing before work begins.

Residential vs. Commercial Package Unit Repair

Residential packaged units

• Typically 2–5 tons, serve the whole home from a roof or pad

• Can be packaged AC + gas heat, heat pump, or electric heat

• DOE notes packaged options eliminate a separate furnace and can simplify footprint and service access.

Commercial rooftop HVAC units (RTUs)

• Commonly condition over 50% of U.S. commercial floor area—a huge efficiency opportunity.

• Benefit from economizers, VFD fan control, and advanced controllers; retrofits can deliver ~25–50% energy savings when implemented correctly.

• AFDD tools help continuously monitor and flag faults for faster, targeted repairs.

We fix both home and business systems. We can help you decide if a targeted control upgrade or planned replacement is the better choice.

Safety & Compliance (Refrigerant, CO, Licensing)

• Refrigerant handling: Only EPA Section 608–certified techs may connect gauges, recover, or charge refrigerant; venting is illegal. We follow all 608 requirements.

• Carbon Monoxide (gas RTUs): Gas-fired sections require annual professional inspection and proper venting to reduce CO risk; keep CO alarms in sleeping areas.

• California license check: Always verify your contractor on the state’s CSLB lookup. cslb.ca.gov+1

Proactive Maintenance = Fewer Breakdowns

A small bit of prevention prevents emergency calls:

• Replace filters and keep coils & drains clean (DOE guidance).

• Follow ASHRAE/ACCA Standard 180 for commercial inspection & maintenance to preserve comfort, efficiency, and IAQ.

• Consider advanced RTU controls and economizer commissioning to catch faults early and cut energy use.

We offer seasonal maintenance plans aligned with these standards.
