Why is my AC running but blowing warm air?

Causes include a clogged filter, a failed capacitor, an active refrigerant leak, or a failing compressor. Turning the system off prevents further mechanical strain; a licensed technician can diagnose which cause is at play before repairing.

Does low refrigerant just mean I need a recharge?

No. An AC doesn't consume refrigerant — low levels mean a leak in the coils or lines. A technician must find and seal the leak before recharging, or the new refrigerant simply leaks out again.

What makes an AC short-cycle on and off?

Short-cycling often comes from a restricted filter, a frozen evaporator coil, an oversized system, or a faulty thermostat. It strains the system and wastes energy, and can cause premature compressor failure if left unaddressed.

Is losing AC on a hot day an emergency?

In extreme heat it can be. For households with elderly members, young children, or medically sensitive individuals, a broken AC is a genuine safety concern and warrants prompt attention from a licensed technician.

Air Conditioning Repair

When an AC system stops cooling during a heat wave, a home gets uncomfortable — and for some residents, unsafe — fast. Failures range from a minor electrical glitch to a major mechanical breakdown, and an accurate diagnosis from a licensed HVAC technician determines whether it's a quick fix or a component replacement.

Symptoms of a Failing AC System

Call for professional diagnosis if you notice:

Warm or lukewarm air from the supply vents.
Weak airflow or uneven distribution through the home.
Short-cycling — the system switching on and off in rapid succession.
Water pooling around the indoor evaporator coil or furnace closet.
Squealing, grinding, or loud clicking from the outdoor condenser.

A licensed technician troubleshoots in order, checking the easy causes first: airflow restrictions, a tripped breaker, a weak capacitor, and refrigerant charge. Treating a symptom — like repeatedly resetting a breaker — without finding the root cause risks destroying expensive parts like the compressor.

The Truth About Low Refrigerant

A common misconception is that an AC "uses up" refrigerant. The system is a sealed loop — if it's low, there's an active leak. Simply topping it off without leak detection wastes money and vents refrigerant to the atmosphere. A technician locates the physical leak, seals or replaces the damaged coil or line, evacuates the system, and pulls a proper vacuum before recharging to manufacturer spec.

When Extreme Heat Becomes a Safety Issue

Because breakdowns cluster on the hottest triple-digit days — exactly when the home needs cooling most — AC repair is frequently time-sensitive. High indoor heat is a documented health risk for elderly residents, infants, and people with medical conditions, so a cooling failure in extreme heat is the kind of situation a licensed technician should address the same the problem arises. Routine tune-ups keep dirty filters or blocked condenser coils from triggering a shutdown when the system is needed most.

In Westwood: What Local Homeowners Should Know

Westwood's housing stock is unusually split between single-family blocks near UCLA and the Wilshire Corridor's high-rise condominium towers, some over 25 stories, most converted from 1920s-60s apartment buildings before later ones were built from scratch as condos. That means a large share of Westwood service calls happen inside HOA-governed buildings with their own engineering staff, freight-elevator booking requirements, and building-management sign-off before a licensed contractor can even reach a unit — very different from a single-family house call. Older sections near Westwood Village — land purchased in 1919 by Arthur Letts, developed by the Janss Investment Company beginning in the early 1920s — have prewar plumbing and electrical that hasn't always kept pace with modern HVAC loads. A contractor working in a Wilshire Corridor high-rise needs the building's insurance and access requirements sorted before a truck ever shows up.
