FAQs
Why do I need a precision A/C tune-up, and how often should it be done?
Even a high-efficiency air conditioner can lose up to 5% of its rated performance each year without proper maintenance. A precision tune-up restores lost capacity, reduces wear, and helps catch small issues before they become expensive breakdowns. In Greenback’s hot, humid summers, we recommend scheduling a professional tune-up once a year—ideally in early spring—so your system is ready when the temperature spikes.
What does your precision A/C tune-up service include?
Our technicians follow a comprehensive 18-point checklist that covers electrical, mechanical, and performance components. We clean condenser and evaporator coils, tighten electrical connections, check refrigerant charge, calibrate the thermostat, inspect the blower motor and belts, test safety controls, clear the condensate drain, and measure airflow and temperature differentials. Before we leave, you’ll receive a written report of findings and recommendations.
How long does a typical tune-up visit take, and do I need to be home?
Most residential tune-ups take 60–90 minutes depending on system accessibility and cleanliness. We do ask that an adult be present to give us access to indoor and outdoor units, answer any questions, and authorize additional work if needed. If you can’t be home, let us know in advance—we can often arrange secure access and review the service report with you by phone afterward.
Will a tune-up really lower my energy bills?
Yes. Dirty coils, loose electrical connections, and incorrect refrigerant levels force your compressor to work harder, consuming more electricity. The U.S. Department of Energy estimates that well-maintained HVAC systems use 15–20% less energy than neglected ones. Customers in Greenback frequently see their summer utility bills drop after a tune-up—sometimes enough to offset the service cost in the same season.
Is a precision tune-up the same as a repair? What if you find a problem during the inspection?
A tune-up focuses on cleaning, testing, and adjusting your equipment to factory specs; it doesn’t include part replacements. If we discover a worn capacitor, leaking coil, or other issue, we’ll show you the problem, explain options, and quote a flat repair price on the spot. Minor fixes such as tightening a wire or lubricating a motor are performed at no extra charge. Larger repairs are only done with your approval.
Do you offer any guarantees or maintenance plans for customers in Greenback?
Absolutely. Every tune-up comes with our 100% Satisfaction Guarantee—if you’re not happy, we’ll make it right. We also offer an Energy-Saver Maintenance Plan that includes two seasonal tune-ups (spring A/C and fall heating), priority scheduling, a 15% discount on repairs, and no overtime fees. Plan members receive service reminders so you never miss critical maintenance.
