Professional Air Conditioning Maintenance & Seasonal Tune-Up in Branson, MO

Reduced airflow is one of the most common efficiency killers and goes unnoticed by homeowners. We measure static pressure in your ductwork, check airflow at supply vents, and verify that your system is moving the volume of air it should. If airflow is weak, we diagnose the cause: clogged filter, dirty evaporator coil, crushed ducts, or undersized ductwork.

• Measure static pressure in return and supply ductwork
• Verify proper filter condition and replacement schedule
• Check airflow velocity at multiple supply registers
• Test for duct leaks that reduce cooling to certain rooms
• Evaluate thermostat placement and operation
• Confirm blower motor speed is appropriate for your system

Refrigerant at the wrong pressure is a silent efficiency robber. Undercharged systems don’t cool well and stress the compressor because it has to work longer to move less refrigerant, driving up amperage and heat. Overcharged systems create dangerously high head pressures and pressure spikes that can burst lines or cause compressor failure. We measure high-side and low-side pressures with calibrated electronic gauges, calculate superheat and subcooling, and compare to manufacturer specs. This is the most critical part of maintenance—a single percentage point of undercharge can cost you 3–5% in cooling efficiency and shorten system life by years.

• Measure high-side and low-side refrigerant pressures with calibrated electronic gauges
• Calculate system superheat and subcooling to verify proper charge balance
• Compare all readings to equipment nameplate specifications and seasonal adjustments
• Check for refrigerant leaks at all solder joints, valve connections, and hose fittings
• Verify refrigerant type matches nameplate (R-410A, R-22, R-32, etc.)—never mix types
• Document pressure trends if system history exists from previous visits
• Discuss refrigerant recovery and proper recharging if system needs adjustment

Compressors don’t just fail; their motors draw increasing amperage as bearings wear. Run capacitors develop high ESR before they fail completely. Contactors get pitted contacts that increase resistance. We test all electrical components and document readings to track trends year over year.

• Measure compressor motor amperage draw against equipment rating
• Test run capacitor with ESR (equivalent series resistance) meter
• Verify contactor operation and inspect contact surfaces
• Check thermostat wiring for loose connections
• Test all safety controls: high-pressure switch, low-pressure switch
• Measure voltage at the unit (should be within ±10% of nameplate)

A dirty evaporator coil reduces efficiency by 10–20% and increases the risk of freeze-up. A dirty condenser coil makes the outdoor unit work harder in the heat. We clean both coils and optimize your system for peak performance.

• Vacuum and chemically clean indoor evaporator coil
• Hose down and clean outdoor condenser coil fins
• Inspect and adjust thermostat settings for your usage
• Test heating/cooling cycle if system is heat pump capable
• Verify defrost cycle operation (if applicable)
• Document all findings on your service report

We sit down with you and review our findings. Here’s what we found, here’s how your system is performing compared to its design specs, and here’s what should be addressed now versus what we recommend monitoring. We provide a written report with all measurements, photos, and recommendations so you have a record.

• Present findings in plain language with visual documentation
• Explain any measurements that are out of spec
• Recommend any repairs or replacements needed soon
• Suggest monitoring items that are slightly off but not urgent
• Discuss filter replacement schedule and seasonal checkups
• Answer questions about your system’s operation and efficiency
• Provide invoice and schedule follow-up visit if needed
