Residential AC Tune-Up in Los Angeles

What our Residential AC Tune-Up includes

Our tune-up is engineered to restore performance, protect components, and improve indoor air quality. We follow manufacturer‑aligned procedures, backed by factory training with Fujitsu, Mitsubishi Elektrik, Midea, Gree, and Hier.

• Airflow and static pressure testing to verify proper duct performance
• Refrigerant charge analysis and temperature split verification
• Deep cleaning of outdoor condenser coil and indoor evaporator access as applicable
• Electrical inspection: capacitors, contactors, connections, wiring, and safety controls
• Thermostat calibration and control sequence verification
• Blower assembly inspection and cleaning recommendations
• Condensate drain inspection and treatment to prevent clogs and leaks
• System start‑up test, amperage draw, and efficiency checkpoints
• Filter check with right‑sizing guidance for airflow and IAQ

After service, you receive a clear, photo‑supported report with prioritized recommendations to help you decide what to address now versus later.

Why an engineering‑grade tune-up matters

Most tune-ups are quick clean-and-go visits. Ours is different. As 4th‑generation engineers with 80+ years in engineering, we diagnose the system as a whole—equipment, ductwork, controls, and load conditions—so your AC delivers real‑world comfort and efficiency, not just good lab numbers.

• Lower energy bills through restored heat transfer and balanced airflow
• Fewer breakdowns thanks to early detection of failing parts
• Quieter operation and longer equipment life
• Cleaner, healthier indoor air aligned with our mission: healthy air at home

Health-first: indoor air quality checks

We assess filter fit and pressure drop, look for biofilm risks at the coil and drain, and identify dust or leakage patterns that indicate duct issues. We can recommend upgrades like high‑performance filters, UV coil treatment, sealing strategies, and ventilation improvements to support a healthier home.

Systems we service

We tune central AC, heat pumps, and ductless mini‑splits from a wide range of manufacturers. Our team holds factory training from Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), and applies the same disciplined process across most residential brands.

Ideal timing for your AC tune-up

Book before peak summer heat to maximize efficiency and comfort. If you notice warm spots, rising energy bills, odd noises, drainage issues, or frequent on/off cycles, your system likely needs attention now.

What to expect on the day

• On‑time arrival and a brief walk‑through of any comfort or noise concerns
• Protective shoe covers and workspace care
• Full diagnostic and cleaning scope as listed above
• Performance verification and a plain‑English, photo‑supported report
• Options prioritized by safety, performance, and budget

Frequently asked questions

How often should I tune my AC?
Once per year is recommended in Southern California, ideally in spring. Heavy coastal exposure or high dust homes may benefit from additional checkups.

Will a tune-up fix comfort issues?
It often does, especially when airflow, coil cleanliness, or charge are at fault. If duct design or controls are the root cause, we’ll show you targeted options.

Do you service heat pumps and mini‑splits?
Yes—our process covers central AC, heat pumps, and ductless mini‑splits.
