An air conditioner that sputters, rattles, or leaves half the house warm has a way of turning a hot California day into a miserable one. Dependable AC repair and maintenance in Oak Park, CA, and nearby areas keeps those problems from ruining your summer, and Galaxy Plumbing, Heating, AC & Solar has been the local team homeowners and businesses trust to keep their cooling running right. Whether your unit needs a quick repair or a regular tune-up, we get things back in shape before the heat gets the better of you.
Serving Los Angeles and Ventura Counties since 1986, Galaxy Plumbing, Heating, AC & Solar is a family-run plumbing and HVAC company based in Oak Park, CA. Our team repairs and maintains cooling systems from every brand for homes and businesses, tackling everything from worn parts and frozen coils to full tune-ups that keep systems humming. Licensed in plumbing, HVAC, and solar, we bring careful, dependable work to every AC job we take on.


The problem usually announces itself right when you need the AC most. Warm air drifting from the vents, a unit that runs nonstop without cooling, rooms that never match the thermostat, or odd noises and puddles near the system all point to something gone wrong inside. On the hottest afternoon of the year, that's the last thing anybody wants to deal with.
Plenty of things can knock a cooling system off its game. A failing capacitor or worn fan motor can stop the unit from starting or moving air, low refrigerant from a leak leaves you with weak cooling, and a frozen evaporator coil chokes off airflow entirely. Dirty coils, clogged drain lines, and a thermostat that's misreading the temperature all pile on, too, and a system that hasn't had regular AC maintenance is far more likely to run into these headaches when the heat is cranking.
Fixing it starts with identifying the root cause rather than throwing parts at the problem. As an experienced air conditioning contractor, our team runs a full diagnostic, checking the capacitor, fan motor, refrigerant levels, coils, and drain line to find exactly what's failing. From there, we handle the central AC repair, whether that means a fan motor swap, clearing a frozen coil, cleaning out a clogged drain line, or sorting a thermostat that's gone haywire, and we walk you through it so nothing feels like a mystery.
When the work's done, your home cools evenly and quietly again, and the system stops chewing through energy trying to keep up. Staying on top of air conditioning maintenance keeps small hiccups from snowballing into pricey breakdowns, stretches the life of your unit, and helps it run at its best through the hottest stretches of the year. That kind of steady, reliable cooling is exactly what we're after on every call.
Our technicians service residential and commercial cooling systems through practical repairs, scheduled maintenance, and support for equipment from every major HVAC brand.

Turn the system off if it runs without cooling, especially when you notice ice, burning smells, loud noises, or water around the equipment. Continuing to operate a struggling unit can worsen problems involving the compressor, motor, coils, drainage, or electrical components.
Most residential systems benefit from professional AC repair and maintenance once a year, preferably before the hottest part of summer arrives. Commercial equipment may need more frequent visits because it often runs longer and serves larger spaces.
Shut off the cooling system if you find ice on the coil or refrigerant lines, as continued operation can damage expensive components. A dirty filter, low airflow, a faulty fan, or a refrigerant problem may cause the freezing, so let the ice thaw and arrange professional service.
Short cycling can result from a dirty filter, thermostat trouble, a clogged coil, low refrigerant, electrical problems, or equipment that does not match the home’s cooling load. An HVAC technician can test the system and fix the source of the issue instead of guessing and replacing parts at random.
Call for emergency AC repair if you smell burning, hear buzzing from electrical components, see smoke, notice severe leaks, or lose cooling during dangerous heat. Turn off the system while you wait, and contact emergency services immediately if you see fire or smoke.
