The Los Angeles90078 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.

Breaker trips every time the system starts
Dead or bulging run capacitor on the condenser
Heat pump stuck blowing cold air in heating mode
Short cycling — on and off every few minutes
Thermostat reading several degrees off from reality
Heating and air conditioning service built around Los Angeles
Whether the complaint is weak airflow upstairs, a furnace that will not stay lit, or an outdoor unit that hums but never starts, the process is the same — a proper diagnostic, a written price, then the repair.
In the 90078 area we see a lot of attic-mounted air handlers. Attic heat soak in summer and cold-soak in winter both shorten component life and make insulation checks part of a proper diagnosis.
The busiest week of our year in Los Angeles is the first stretch of sustained may weather. Systems that idled all season fail in clusters.

Los Angeles90078 HVAC questions, answered
Do you offer maintenance plans?
We do. A two-visit plan in California covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Los Angeles, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Los Angeles we see algae and dust clogging drain lines constantly during May through October. It is a fast fix but ignoring it ends in ceiling damage.
What does a new system cost in Los Angeles?
A complete residential replacement in the 90078 area generally lands between $6,000 and $13,000 installed, depending on capacity, efficiency rating and how much ductwork has to be modified. We always perform a Manual J load calculation first, because an oversized unit costs more to buy and runs worse than a correctly sized one.
Do you handle ductless mini-split systems?
Yes. Ductless installations have grown quickly in California, particularly in older homes without existing ductwork. We service indoor heads, clean filters and drain lines, check line-set insulation and diagnose communication faults between heads and the outdoor unit.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
