Cut Costs and Extend System Life with AC Maintenance

An AC tune-up—also known as preventive maintenance—is a professional check-up that keeps your system running smoothly, efficiently, and reliably. During a tune-up, a trained technician inspects and adjusts key components like panels, controls, safety switches, ductwork, and refrigerant levels. The goal is to catch small issues before they turn into major problems.

Lower Energy Bills

When your AC system is clean, properly calibrated, and free of hidden issues, it runs more efficiently. That means your home stays cool without your energy bill spiking. A tune-up corrects small inefficiencies—like dirty coils or misaligned components—that can quietly increase your monthly costs.

Prevent Costly Breakdowns

Most breakdowns don’t happen overnight. They’re the result of small issues that go unnoticed until something fails. A tune-up helps catch those early signs—like worn parts or restricted airflow—before they become a bigger, more expensive repair.

Extending the Life of Your AC Unit

AC units that are maintained regularly last longer, plain and simple. When a system isn’t working harder than it needs to, it experiences less wear and tear. That means fewer repairs, better performance, and a system that keeps running well beyond its warranty.

Turn a Tune-Up Into Year-Round Peace of Mind

Why stop at one visit? With a MightyServ membership, you get two seasonal tune-ups, priority scheduling, and exclusive discounts on parts and service—all starting at a low monthly rate.

Enjoy up to $780/year in included services and savings—like evaporator coil cleaning, contactor or capacitor replacement, and more.

Consider This Before Skipping Your Yearly Maintenance

Skipping your annual AC maintenance might seem like no big deal—but in Southern California, especially in the Valley where triple-digit heat is the norm, it can cost you. We’ve seen avoidable problems lead to full system failure—and a $10,000+ replacement homeowners didn’t plan for. A quick, affordable tune-up now is the best way to protect your comfort and your wallet.

What We Check During Every MightyServ AC Tune-Up

Our tune-ups go beyond a quick look. We inspect, clean, and calibrate every part of your AC system to keep it running smoothly and efficiently all season long.

Cooling Performance & Efficiency

✅ Thermostat Calibration – We make sure your thermostat reads correctly and communicates properly with your system.

✅ Evaporator and Condenser Coil Cleaning – Dust and grime on the coils can restrict airflow and reduce cooling power. We clean them thoroughly to restore efficiency and keep your system running smoothly.

✅ Refrigerant Level Check & Pressure Testing – We ensure your system has the proper refrigerant charge and inspect for any signs of a leak or imbalance.

✅ Temperature Split Measurement – We check the difference between return and supply air to confirm that your system is cooling as it should.

✅ Smart Thermostat or Zoning System Calibration – If your system includes smart controls or zoning, we test and calibrate them to ensure accuracy and functionality.

✅ Fan Blade Inspection – We check blades on both the indoor and outdoor units for cracks, warping, or imbalance.

✅ Compressor Performance Check – We verify that your compressor is operating efficiently and not overworking, which could lead to system failure.

✅ Refrigerant Line Insulation Inspection – We inspect insulation for cracks or damage that can affect performance and increase energy use.

Airflow & Circulation

✅ Air Filter Replacement or Cleaning – Clean filters improve air quality, prevent strain on the system, and ensure proper airflow.

✅ Blower Motor Inspection – We evaluate the blower motor to ensure it’s delivering consistent airflow and not showing signs of wear.

✅ Ductwork Visual Inspection – We visually inspect accessible ducts for disconnections, blockages, or visible damage.

✅ Fan Belt Condition (if applicable) – In systems with belts, we check for signs of fraying, tension loss, or misalignment.

Electrical & Safety Systems

✅ Electrical Connection Tightening – Loose connections are a major cause of breakdowns. We inspect and tighten all key terminals and wiring.

✅ Capacitor & Contactor Testing – We test these components to ensure your system starts and runs reliably without electrical issues.

✅ Voltage & Amperage Checks on All Motors – We measure motor loads to catch early warning signs of stress or failure.

✅ System Controls & Safety Check – We inspect the control board, relays, and safety systems to ensure reliable operation.

✅ Surge Protection Check (if installed) – We confirm that your system’s surge protector (if installed) is in place and functioning.

✅ Secure All Panels & Covers – We reseal access panels after service to prevent air leaks, vibration, or damage.

✅ Noise & Vibration Evaluation – Unusual sounds or vibrations often point to loose parts or developing problems—we catch them early.

✅ System Startup & Shutdown Test – We run a full system cycle to confirm smooth, reliable operation from start to stop.

Drainage & Moisture Control

✅ Condensate Drain Line Cleaning – We flush the drain line to prevent clogs that could cause water damage or mold growth.

✅ Safety Shut-Off Switch Testing (if applicable) – We test any safety shut-offs to ensure they’ll trigger properly in case of a leak or overflow.

Preventive Maintenance & Documentation

✅ Lubrication of Moving Parts – We lubricate motors and other components to reduce friction and extend system life.

✅ Document System Age, Model, and General Condition – We note your system’s specs and condition so you have a clear service history and replacement roadmap.

DON’T WANT THE FULL TUNE-UP?

If you don’t want the full tune-up, we strongly recommend a filter change!

Remember: your air conditioner takes whatever particles are inside your home and spreads it around! You can capture and contain those contaminants with a clean filter.

Our safe filter change includes safe removal of your old filter (bagging and disposal), disinfecting the surfaces inside of your furnace, and installation of a new filter.
