30-Point AC Maintenance & Tune-Ups

Your air conditioner works hard through long, humid cooling seasons. Even when it seems to be running normally, dust buildup, weak airflow, worn electrical parts, low refrigerant symptoms, or drainage issues can slowly reduce performance. AC maintenance is a scheduled service visit that helps catch those problems early, before they turn into uncomfortable rooms, higher energy use, or an unexpected breakdown.

R.S. Andrews provides AC maintenance for homeowners who want their cooling system inspected, cleaned, tested, and adjusted by experienced HVAC professionals. The goal is simple: help your system cool more consistently, run more efficiently, and last as long as possible.

AC Maintenance Services We Offer

Routine maintenance does more than just keep your system running—it helps you stay ahead of breakdowns, inefficiencies, and unnecessary repairs. At R.S. Andrews, we offer a full range of services designed to protect your cooling system season after season.

Full-System Tune-Ups

Our team inspects your entire system from top to bottom, checking components, cleaning coils, and testing airflow. We also tighten electrical connections and make sure safety switches are functioning properly. It’s a full checkup that helps prevent mid-summer surprises.

Filter Replacements & Airflow Checks

Clean filters and balanced airflow make a big difference in how your home feels. We inspect for blockages, swap out filters if needed, and ensure your system is moving air efficiently. Better airflow means better comfort and better energy use.

Refrigerant Level Checks & Coil Cleaning

Low refrigerant or dirty coils can make your AC work harder than it should. We check for proper charge and clean evaporator and condenser coils for maximum performance. It helps your unit cool faster and run longer.

Thermostat Calibration

Even a small thermostat issue can throw off your entire system. We test the accuracy of your readings and make sure your settings match your schedule and preferences. When needed, we recommend simple upgrades for better control.

Drain Line & Safety Checks

Clogged drain lines and unchecked sensors can lead to water damage or system shutoffs. We clear debris, test for leaks, and verify that everything is draining the way it should. A little prevention here can save a big headache later.

Our Full 30-Point AC Tune-Up Process:

System Interior & Airflow Inspection

We begin with a detailed internal review of the equipment and air-moving components.

• High Resolution (1080 dp) Deep Internal Scan
• Camera scan blower assembly, inspect the blower wheel and motor
• Check blower capacitor
• Measure blower amps
• Inspect evaporator coil
• Inspect heat exchanger
• Measure temperature difference across evaporator coil
• Replace standard 1 inch pleated filter
• Inspect ductwork
• Inspect flue pipe

This portion verifies airflow condition, internal cleanliness, and proper system operation from the air handler outward.

Outdoor Unit & Refrigerant System

Next, we evaluate refrigerant performance and condenser condition to ensure the system can reject heat properly.

• Check refrigerant charge
• Tighten all refrigerant service valve caps and covers
• Inspect condenser coil
• Clean out debris from bottom of condenser
• Inspect fan blade
• Check low and high pressure switches

These steps help prevent efficiency loss, overheating, and compressor strain during peak summer demand.

Drainage & Moisture Protection

Condensate management protects your home and your system from water damage and shutdowns.

• Flush condensate drain line
• Check all drain safety switches
• Check condensate pump and line (if applicable)

Clearing and testing these components reduces the risk of water backups and float switch trips.

Electrical & Component Testing

Air conditioners operate under significant electrical load. We measure and verify performance at each critical point.

• Test high voltage at disconnect and condenser
• Check and tighten all electrical connections
• Check and tighten all low voltage connections
• Measure compressor mega ohms
• Measure compressor amps
• Measure fan amps
• Test compressor run and start capacitors
• Check compressor terminal connections
• Check thermostat operation

This testing helps identify weak capacitors, wiring concerns, or compressor issues before they cause breakdowns.

Final Documentation & Completion

Before leaving your home, we complete the final steps that ensure everything is documented and left in proper condition.

• Update inspection label
• Clean up after tune-up

Every maintenance visit follows this full 30-point checklist. If we find wear, electrical weakness, or refrigerant concerns, we’ll explain what we’re seeing and what it means for the system’s reliability going forward.

Why Routine AC Maintenance Matters

Air conditioning systems often lose performance gradually. You may not notice the change until the house feels uneven, the system runs longer than usual, or the utility bill starts climbing. Maintenance helps slow that decline by keeping the equipment cleaner, safer, and better calibrated.

A properly maintained AC system can help:

• Improve cooling consistency throughout the home
• Reduce unnecessary strain on major components
• Support better energy efficiency
• Lower the chance of mid-season breakdowns
• Protect the system’s usable life
• Identify repair needs before they become emergencies

Maintenance does not guarantee that a system will never fail. No honest service company should promise that. What it does is give the equipment a better chance of performing the way it was designed to perform, especially when outdoor temperatures stay high for long stretches.

When to Schedule AC Maintenance

Most homes benefit from AC maintenance once a year, ideally before the heaviest part of the cooling season. Spring is a common time to schedule service because it gives the system a chance to be checked before it has to run daily.

You may also want maintenance if:

• The system has not been serviced in more than a year
• Cooling feels weaker than it used to
• The system runs longer than normal
• Some rooms feel warmer than others
• The outdoor unit looks dirty or overgrown
• You want the system checked before peak summer use

If the system is already blowing warm air, making loud noises, leaking heavily, or shutting down, that is no longer a maintenance issue. In that case, schedule AC repair instead.

Maintenance for Older AC Systems

Older air conditioners need careful attention. As parts age, the system may still cool the home but work harder to do it. Maintenance helps identify whether the equipment is still operating within a reasonable range or showing signs of decline.

If a technician finds repeated failures, major efficiency loss, or expensive repair concerns, they may discuss whether AC installation and replacement should be considered. That recommendation should come from the condition of the equipment, not from pressure during a routine tune-up.
