Central AC Questions Homeowners Ask
Once yearly, ideally before summer heat begins—usually in April or May. Annual maintenance keeps the system running efficiently, extends equipment life, and catches problems early. If you use your AC heavily or live in dusty areas, twice-yearly service (spring and fall) provides extra protection.
A low charge happens when your system is undercharged from the factory or loses refrigerant from a leak. If there’s no leak, topping off refrigerant solves the problem temporarily. If there IS a leak, simply adding refrigerant masks the issue—the refrigerant leaks out again, and you’re back where you started. We find leaks and repair them, then charge the system correctly.
Multiple causes: low refrigerant from a leak, a blocked condenser coil, a failed compressor, a stuck valve, or a broken thermostat. We diagnose the actual problem instead of guessing. Sometimes it’s a simple fix; sometimes it’s a system decision. Either way, you get honest information.
SEER (Seasonal Energy Efficiency Ratio) measures cooling output versus electricity used. Higher SEER means lower energy bills. Modern systems are 16–18 SEER; older systems might be 8–10 SEER. Over 15–20 years, upgrading to a high-SEER system often pays for itself through reduced cooling costs, plus you get better cooling performance and quieter operation.
In Houston’s climate, you won’t be running AC in winter, but you should have the system inspected before next summer and NOT shut it down completely. Some components (like the compressor) benefit from occasional lubrication even during off-season. Before winter, we run a final service to prepare the system for dormancy.
Our maintenance visits include refrigerant pressure checks, electrical testing, capacitor inspection, coil cleaning, filter replacement, and thermostat calibration. We test the system under load to confirm it’s performing to spec. If we find issues, we discuss repair options before going ahead.
Quality central AC systems last 15–20 years with regular maintenance. Armstrong and Samsung units we install are built for that range. After 15 years, repair costs often climb as components wear; replacement becomes more economical.
Possibly. Uneven cooling sometimes stems from blocked ducts, closed vents, or ductwork leaks. We check duct sealing and airflow as part of diagnosis. If ducts are genuinely dirty or blocked, we recommend cleaning; if the issue is elsewhere (compressor wear, refrigerant loss), we focus on that.
One-time repairs fix immediate problems. Maintenance plans include scheduled tune-ups, priority scheduling if emergencies happen, and often discounts on repairs. Plans pay for themselves if you use the discounts—plus you avoid surprise breakdowns on the hottest days.
Usually, yes—but not always. We evaluate your ducts for leaks, proper sizing, and compatibility with new equipment. Oversized or undersized ducts reduce efficiency even with a new system. Sometimes adding duct sealing or balancing makes sense; sometimes upgrading ducts is worth the investment. We explain the trade-offs.
