Ducted Heat Pump Maintenance & Tune-Up in Worth, IL

We arrive with diagnostic equipment and systematically test your heat pump in both operating modes. We measure refrigerant pressure in heating mode, then switch to cooling and measure pressure again. We verify the reversing valve switches between modes reliably, test the backup electric heater activation sequence, and check airflow through the ductwork. We listen for unusual sounds indicating wear and visually inspect components for corrosion or damage before moving to the next stage of the inspection.

• Measure refrigerant pressure in heating mode and record data
• Switch to cooling mode and verify pressure changes correctly
• Test reversing valve switch operation in both directions
• Verify the backup electric heater activates only on very cold days
• Measure supply air temperature in both heating and cooling
• Inspect outdoor unit, indoor handler, and ductwork for wear

Refrigerant must be at the correct level year-round—low charge reduces heating and cooling, while overcharge damages the compressor. We verify charge against OEM specifications in both heating and cooling modes. If charge is low, we investigate for leaks using electronic detection and UV dye. We repair leaks if found and recharge to manufacturer specification exactly, documenting every reading along the way.

• Verify refrigerant charge in heating mode against nameplate spec
• Verify refrigerant charge in cooling mode against nameplate spec
• Calculate superheat and subcooling to confirm proper operation
• Use electronic leak detection to find any refrigerant escape
• Repair refrigerant line leaks and fittings if found
• Recharge to OEM specification using certified scales and gauges

Dirty evaporator and condenser coils reduce heat transfer, forcing your heat pump to work harder and consume more energy in both seasons. We clean both coils chemically and mechanically, removing dirt, dust, and debris. We inspect and replace the system filter, lubricate moving parts, and tighten any loose mechanical or electrical connections that could cause premature wear or failure down the line.

• Clean indoor evaporator coil with safe chemical cleaner
• Pressure wash outdoor condenser coil carefully
• Remove leaves, debris, and dirt buildup from outdoor unit
• Replace or clean system air filter
• Inspect blower wheel for dust and debris accumulation
• Lubricate blower motor and outdoor fan motor bearings

A heat pump's electrical system must deliver proper power to the compressor, fan motors, reversing valve, and control board. We measure voltage at key terminals, test the capacitor for proper microfarads rating, verify the contactor switches smoothly, and check ground connections. We test all safety controls and ensure proper operation under heating and cooling load, flagging any component showing early signs of wear.

• Measure voltage supply to outdoor unit and indoor handler
• Test compressor capacitor for proper rating and function
• Test contactor operation under heating and cooling load
• Verify all electrical connections are tight and corrosion-free
• Test ground connections for safety and equipment protection
• Confirm thermostat calls for heating and cooling reliably

We provide a written maintenance report documenting every test result, what was cleaned or adjusted, and recommendations for any future work. We explain findings in plain language and discuss upcoming maintenance needs. Maintenance plan members receive priority booking for the following year, ensuring your system gets attention at the start of each season without having to remember to call us first.

• Provide itemized service report with all test data and findings
• Explain refrigerant charge, electrical test results, and efficiency
• Recommend filter replacement frequency for your home
• Discuss upcoming repair needs or minor adjustments
• Schedule next year's maintenance visit (plan members get priority)
• Answer all questions about heat pump operation and energy efficiency
