Air Conditioning Repair by Sauer HVAC Pros

Expert technicians who diagnose, service, and repair your cooling system right the first time.

5 Highlights on Air Conditioning Repair

Certified EPA technicians handle all refrigerant types including R-410A, R-22, and R-32 with proper recovery and charging procedures that meet federal compliance standards.

Same-day diagnostic service gets your air conditioner back online fast. Our technicians arrive with fully stocked vans carrying capacitors, contactors, fan motors, and common replacement parts.

Comprehensive system testing includes superheat and subcooling measurements, static pressure readings, and delta T calculations to pinpoint exactly why your unit isn’t cooling properly.

Transparent flat-rate pricing means you’ll know the repair cost before we start work. No hidden fees. No surprise charges for refrigerant or labor.

All repairs backed by warranty covering both parts and labor. We stand behind every compressor replacement, coil repair, and electrical fix we perform on residential and commercial systems.

Why Choose Our Air Conditioning Repair

Air conditioning repair from Sauer HVAC Pros delivers reliable results backed by NATE-certified expertise. Our technicians complete ongoing training on split systems, package units, mini-splits, and ductless configurations from all major manufacturers.

We’ve repaired thousands of cooling systems across residential and commercial properties. That experience matters when diagnosing tricky problems like intermittent compressor failures, refrigerant leaks at flare fittings, or control board malfunctions that other contractors miss.

Our diagnostic process goes beyond surface symptoms. We measure airflow in CFM, check capacitor microfarad ratings with precision meters, and verify refrigerant charge using manifold gauge sets. This thorough approach identifies root causes rather than just treating symptoms.

Every repair truck carries professional-grade equipment. Vacuum pumps, electronic leak detectors, refrigerant scales, and combustion analyzers help us work efficiently. We don’t waste your time running back to the shop for tools.

Sauer HVAC Pros guarantees satisfaction on every air conditioning repair. If your system fails within our warranty period, we return at no additional charge. Our reputation depends on keeping your home cool and comfortable.

Signs You Need Air Conditioning Repair

Air conditioning repair becomes necessary when your system shows specific warning signs. Catching these problems early prevents compressor failure and costly replacements.

Warm air from supply registers indicates several possible issues. Your system might be low on refrigerant due to a leak in the evaporator coil or lineset connections. The compressor could be failing to pressurize refrigerant properly. A faulty expansion valve or metering device might also restrict refrigerant flow to the evaporator.

Short cycling behavior occurs when your air conditioner runs briefly then shuts off repeatedly. This pattern often points to an oversized unit, a clogged filter restricting airflow, or a malfunctioning pressure switch. Short cycling strains the compressor and drives up electricity costs significantly.

Unusual sounds during operation demand immediate attention. Grinding noises suggest worn fan motor bearings. Clicking sounds may indicate a failing contactor or relay. Hissing points toward refrigerant escaping through a corroded coil or loose flare fitting. Banging often means a loose blower wheel or damaged compressor mount.

Ice formation on the evaporator coil signals restricted airflow or low refrigerant charge. Dirty filters, collapsed ductwork, or a failing blower motor reduce air movement across the coil. Refrigerant leaks drop system pressure and cause the evaporator temperature to fall below freezing.

High humidity indoors despite the system running suggests your evaporator coil can’t dehumidify properly. The coil might be dirty, the refrigerant charge incorrect, or the blower speed set wrong for your ductwork configuration.

Our Air Conditioning Repair Process

Air conditioning repair at Sauer HVAC Pros follows a systematic approach that identifies problems accurately and fixes them permanently.

Step 1: System Inspection. Our technician examines your condenser unit, air handler, thermostat, and visible ductwork. We check the disconnect, inspect electrical connections, and note the system’s age and model number from the data plate.

Step 2: Diagnostic Testing. We connect our manifold gauge set to measure suction and head pressure. Temperature readings at the supply and return reveal delta T. We test capacitors, measure amp draw on motors, and verify thermostat signals reach the control board.

Step 3: Problem Identification. Test results pinpoint the failure. Low superheat might indicate an overcharged system or restricted airflow. High head pressure could mean a dirty condenser coil or failing condenser fan motor. We explain findings in plain terms.

Step 4: Repair Execution. With your approval, we complete the repair using quality replacement parts. Refrigerant work includes proper recovery, evacuation, and charging by weight. Electrical repairs meet code requirements. We braze copper connections when replacing coils or linesets.

Step 5: Performance Verification. After repairs, we retest the entire system. Pressure readings, temperature splits, and amp draws must fall within manufacturer specifications before we consider the job complete.

FAQs About Air Conditioning Repair

What causes an air conditioner to stop cooling? Several components can fail and stop cooling. Low refrigerant from leaks prevents proper heat transfer. Dead capacitors won’t start the compressor or fan motors. Frozen evaporator coils block airflow entirely. Faulty thermostats fail to signal the system to run. Our diagnostic process identifies which component has failed.

When should I repair versus replace my AC unit? Age and repair cost guide this decision. Systems under 10 years old with minor failures like capacitors or contactors deserve repair. Units over 15 years requiring compressor replacement or major refrigerant work often cost more to fix than replace. We provide honest assessments based on your system’s condition and remaining lifespan.

Why does my air conditioner run constantly but not cool? Continuous operation without cooling typically indicates low refrigerant charge, a failed compressor, or severely restricted airflow. The system runs trying to reach thermostat setpoint but lacks capacity. Dirty condenser coils, collapsed ductwork, or undersized equipment for your home’s cooling load can also cause this symptom.

How long does a typical AC repair take? Most repairs complete within one to three hours. Simple fixes like capacitor or contactor replacement take under an hour. Refrigerant leak repairs requiring brazing and evacuation need two to three hours. Compressor replacements may require four to six hours depending on system access and refrigerant recovery requirements.

Can I recharge my own air conditioner refrigerant? Federal law requires EPA Section 608 certification to purchase and handle most refrigerants. Improper charging damages compressors and reduces efficiency. Adding refrigerant without finding and repairing leaks wastes money and harms the environment. Professional technicians charge systems by weight using proper recovery and evacuation procedures.

Does homeowner insurance cover AC repair? Standard policies typically exclude mechanical breakdown and normal wear. Coverage may apply if a covered peril like lightning or falling debris damaged your system. Check your policy or contact your insurance agent for specific coverage details on your air conditioning equipment.
