Standard AC Inspection Checklist

Regular maintenance is about more than just swapping out filters. Our detailed AC inspection checklist ensures every component of your system is evaluated, cleaned, tested, and fine-tuned for top performance and long-term reliability. Here’s what we check during every maintenance visit:

Replace Air Filters: Air filters play a vital role in capturing dust, pollen, and airborne particles to maintain fresh, clean air in your home. However, as time passes, they can get blocked, leading to lower indoor air quality and putting extra pressure on your HVAC system. Replacing or cleaning them every 1-3 months improves indoor air quality, enhances system efficiency, and helps extend the lifespan of your unit.
Inspect and Calibrate Thermostat: The thermostat is the control center of your HVAC system, and ensuring it’s calibrated correctly is crucial for maintaining consistent and accurate temperature control. A properly calibrated thermostat prevents unnecessary energy usage, helps reduce utility bills, and ensures your home stays comfortable year-round.
Test System Startup and Shutdown Cycles: Starting and shutting down your HVAC system are key processes that should function smoothly. Testing these cycles regularly ensures your system powers up and turns off correctly, reducing the risk of malfunctions or sudden breakdowns. This helps maintain a reliable and efficient performance over time.
Clean Condenser and Evaporator Coils: The condenser and evaporator coils are key components in regulating your home's temperature. As dust and debris accumulate on them over time, their performance can decline, making your HVAC system work overtime to maintain comfort. Regular cleaning ensures optimal heat exchange, improves energy efficiency, and prevents costly repairs due to overworked equipment.
Inspect Electrical Wiring and Connections: Your HVAC system's electrical wiring and connections are vital for safe and efficient operation. Loose or damaged wires can lead to short circuits, system failures, or even fire hazards. Regularly inspecting these components ensures everything is secure, in good condition, and operating safely.
Evaluate Airflow and Check Duct Integrity: Proper airflow is essential for effective heating and cooling. Blocked or leaky ducts can compromise efficiency, increase energy costs, and make your system work harder than necessary. Inspecting airflow and ductwork helps identify blockages, cracks, or leaks that need to be addressed to ensure optimal performance and lower energy consumption.

With this comprehensive checklist, we catch problems early, before they catch you off guard, ensuring smooth operations and peace of mind.

Signs Your AC Is Operating Below Peak Performance

Is your AC showing signs of strain? Many homeowners don't realize their system is underperforming until it's too late. Catching issues early can help you avoid breakdowns and costly emergency services.

Uneven Cooling: Some rooms feel too hot while others are too cold, indicating poor air distribution, ductwork issues, or an imbalance in the system that affects its ability to maintain consistent temperatures throughout the house. Addressing this may involve inspecting vents, balancing dampers, or evaluating the HVAC design.
Weak or Warm Airflow: The air coming from the vents feels weak or not cool enough, often caused by clogged filters, leaky ducts, or a failing compressor. This reduces the system’s overall efficiency and comfort. Routine upkeep—like changing air filters and sealing ductwork—can significantly improve airflow and system efficiency.
Strange Sounds: Unusual noises like banging, rattling, or squealing could mean parts of the system are loose, worn out, or damaged, which can lead to further breakdowns and require immediate professional attention. Ignoring these sounds can result in higher repair costs over time.
Frequent Short Cycling: The system turns on and off more frequently than usual, placing extra strain on the unit, which might indicate a thermostat issue, electrical problems, or malfunctioning internal components. Professional diagnostics can identify the exact cause and prevent long-term wear on the system.
Moisture or Leaks Around the Unit: Water pooling near the AC unit might result from a clogged drain line or a refrigerant leak. Both can cause further damage to the system and should be promptly repaired. Left unattended, these leaks can lead to mold growth or more expensive repairs.

If your AC system is displaying any of these symptoms, it’s time for a tune-up before the summer heat arrives in full force.

DIY vs. What Requires a Technician

Some light maintenance tasks can be safely handled on your own, while others are best left to trained professionals. Understanding the difference can help you avoid unnecessary costs, wasted time, and added frustration.

Simple DIY Maintenance Tips:

Replace air filters every 1–3 months
Clear debris from around the outdoor condenser unit
Keep vents and registers unblocked
Monitor your thermostat settings for efficiency
Ensure indoor return air grilles are clean

These tasks are great for regular upkeep and can boost your AC’s efficiency between professional visits.

What You Should Leave to the Pros:

Checking and refilling the refrigerant
Electrical diagnostics or repairs
Deep cleaning the evaporator or condenser coils
Inspecting internal components like the blower motor or capacitor
Sealing or repairing ductwork

Professional servicing ensures safety, preserves warranties, and keeps your system operating at peak efficiency. If you're unsure, always call the experts at One Choice Mechanical.
