Why Tune-Ups Matter More in Katy Than Anywhere Else
A standard HVAC system in Chicago runs about 4 months of cooling and 4 months of heating — roughly 2,400 hours per year. The same system in Katy runs 8–10 months of active service — up to 4,500 hours annually. That's nearly double the wear in the same calendar year.
Small issues that a northern homeowner might not notice for two seasons — a slightly low refrigerant charge, a mildly dirty condenser coil, a capacitor reading at 70% capacity — become system failures in Katy because the equipment simply runs so much more. Annual tune-ups are not optional maintenance here. They are the difference between an 8-year system and a 20-year system.
Our 21-Point Tune-Up Inspection Checklist
Every tune-up visit covers the complete system — indoor air handler and outdoor condenser unit:
- Refrigerant pressure & superheat check
- Condenser coil cleaning (chemical flush)
- Evaporator coil inspection
- Capacitor voltage & microfarad test
- Contactor pitting & wear inspection
- Blower motor amp draw
- Condensate drain flush & pan treatment
- Filter replacement (standard 1" included)
- Thermostat calibration & staging test
- Temperature differential (supply vs. return)
- Duct static pressure measurement
- Electrical connections & wire condition
- Disconnect & breaker size verification
- Outdoor unit clearance & airflow
- Refrigerant line insulation condition
- Gas valve & ignition system (heating)
- Heat exchanger visual inspection
- Flue draft & combustion air (gas systems)
- Belt & bearing condition (older air handlers)
- Safety float switch test
- Full written report with photos
Spring AC Tune-Up — Book Before April
The best time for your AC tune-up is March or early April — before Katy's temperatures start climbing into the 90s and our schedule fills. A spring tune-up ensures your system enters peak season fully charged, clean, and running at its rated SEER2 efficiency. Waiting until June means you're booking into a 2–3 week backlog and paying emergency-adjacent rates.
💡 Maintenance Plan: Ask about our Katy Comfort Club membership. For a flat monthly fee, you receive two tune-ups per year (spring AC + fall heat), priority emergency scheduling, 15% discount on all repairs, and no overtime charges — ever. Most members save $200–$400 annually compared to paying per visit.
Fall Heating Tune-Up — Book Before November
Because Katy's heating season is short and unpredictable — a Blue Norther can arrive in late October with almost no warning — fall tune-ups are critical. Our heating inspection verifies ignitor condition, heat exchanger integrity, gas valve operation, and heat pump defrost function before you actually need them on a 28°F night.
We recommend scheduling fall heating service in September or October. This gives us time to order any non-stock parts before the first cold snap, rather than scrambling during peak demand.
What Happens If We Find a Problem?
We document everything — photos, measurements, readings — and present you with a clear written report. We'll explain what we found, how urgent it is, and what it costs to fix. There's no pressure. You choose what to repair and when. We just make sure you have the information to make a smart decision before the issue becomes an emergency.
