A system that runs constantly but leaves one Pomona room hot, feels humid indoors, or drives your bill up isn't broken — it's underperforming. We measure instead of guess at what's dragging on performance.

Not every Air Conditioning Repair call in Pomona is a broken system — plenty run constantly, cool unevenly, or leave the air feeling clammy despite the thermostat reading right. Comfort complaints are almost always a combination of factors, so we test all three.
What every performance visit includes.
Airflow, pressure, and temperature split all get measured instead of a quick 'seems fine' check.
Local staging means most Pomona visits happen within days, not weeks.
You know the assessment cost before we start, credited toward repairs.
Anemometers and manometers measure airflow and pressure rather than estimating by feel, not guesswork.
The most common Pomona comfort complaints, and how we resolve them.
Register-by-register readings pinpoint the cooling loss before recommending dampers or resizing.
Sticky air often means the system is short-cycling or oversized, not properly pulling moisture out — we check both together.
Dirty coils, low refrigerant, and duct leakage all quietly increase runtime and cost, and we check each during the visit.
Excess static pressure strains the blower and cuts airflow throughout the Pomona house, since excess pressure quietly shortens blower motor life.
Charge issues rarely throw an obvious error, so we verify against factory targets.
Buildup on either coil insulates against heat transfer, and a clogged filter compounds it, since the two problems reinforce each other.

Four steps to figuring out what's really wrong.
Describe the comfort complaint and we schedule an assessment and we'll get it scheduled.
The measurement tools come already staged — no return trip for gauges.
Readings are taken and explained before any repair is proposed, then quote a flat-rate fix.
We re-test after the repair to confirm performance actually improved, not just assumed.
Reviews from actual diagnostic visits.
Second floor was always warmer than the first no matter what we set the thermostat to. Turned out the return duct was undersized for that whole level.
— W. Renaud, homeowner
Electric bill jumped almost $80 in a single month with no lifestyle change. They found a refrigerant undercharge that a previous company missed entirely.
— A. Sokolov, homeowner
Basement always felt swampy even when the AC ran constantly. Turns out the system was oversized for the space, adjusting settings fixed it without new equipment.
— G. Nakamura, homeowner
We assumed our old ductwork was fine since the house 'felt okay.' The pressure test showed otherwise and the fix noticeably improved airflow upstairs.
— P. Ekwueme, homeowner

What people usually ask first.
A smaller fix usually solves it, but we measure before recommending either.
Usually oversizing or short-cycling that doesn't give the system enough runtime to dehumidify is the common culprit.
Duct leakage losses show up directly on the bill.
Smaller fixes happen same visit, bigger jobs get quoted separately.
Efficiency losses are often invisible until the bill arrives — the assessment catches them early.
Typically under two hours for airflow, pressure, and charge.
