Coil cleaning
Condenser and evaporator coil cleaning — the single biggest factor in cooling efficiency and energy cost.
Refrigerant pressure check
EPA Section 608 certified to check and handle refrigerant safely. Low charge flags a leak we'll diagnose.
Electrical & capacitor test
Capacitor, contactor, and connection inspection — weak capacitors are the most common summer failure.
Condensate drain clearing
Clogged drain lines cause water damage and shutoffs. We clear and flush the line.
Airflow verification
Filter check, blower inspection, and temperature-split measurement to confirm the system is cooling properly.
$0 service call with work
$85 diagnostic fee waived when you proceed.

How Epic Star tunes up air conditioners in Los Angeles
In Los Angeles, an AC system that limps through the first heat wave usually fails on the hottest day — when every HVAC company in the city is booked solid. A spring tune-up is cheap insurance. We clean the parts that lose efficiency, test the parts that fail first, and tell you honestly whether your system is in good shape or heading toward a bigger repair.
What a tune-up covers
The biggest efficiency factor is coil cleanliness. Condenser coils outdoors collect dust, pollen, and debris; evaporator coils indoors collect a film that insulates them from the air they’re meant to cool. We clean both. We check refrigerant pressures (EPA Section 608 certification is legally required for this), test the run capacitor and contactor — the most common summer failure points — inspect electrical connections, clear and flush the condensate drain line, check the filter and blower, and measure the temperature split across the coil to confirm the system is actually cooling to spec.
Why the capacitor matters most
If there’s one part that strands LA homeowners every July, it’s the run capacitor. It weakens gradually, then fails in extreme heat. A capacitor test during a tune-up costs nothing extra and a replacement is inexpensive — far cheaper than an emergency call during a heat wave, or the compressor damage a failing capacitor can cause.
Refrigerant: we check, we don’t just top off
A low refrigerant charge is not normal wear — refrigerant doesn’t get “used up.” Low charge means a leak. We check pressures and, if they’re low, locate the leak and explain your options. Topping off a leaking system is wasteful and violates EPA best practice, so we don’t do it blindly.
Our scope: full-service HVAC
We do tune-ups, window and mini-split service, thermostat work, and system replacement coordination. If your system is at the end of its life, we’ll tell you plainly what’s needed and handle the project through completion — one call, one point of contact.

Real AC Tune-Up in Los Angeles jobs we've completed
Common issues we fix
AC running but not cooling well
Most likely causes:
- Dirty condenser or evaporator coils
- Low refrigerant charge (indicates a leak)
- Clogged air filter restricting airflow
- Failing capacitor weakening the compressor
AC unit won't turn on
Most likely causes:
- Failed run capacitor
- Tripped breaker or blown fuse
- Faulty contactor
- Thermostat wiring or battery issue
Water pooling near the indoor unit
Most likely causes:
- Clogged condensate drain line
- Cracked or overflowing drain pan
- Frozen evaporator coil thawing
- Disconnected drain hose
AC short-cycling (turns on and off rapidly)
Most likely causes:
- Dirty coils causing overheating
- Refrigerant charge problem
- Oversized system or thermostat placement
- Failing compressor or capacitor
Higher than normal energy bills
Most likely causes:
- Dirty coils forcing the system to run longer
- Low refrigerant
- Clogged filter
- Aging compressor losing efficiency
Frequently asked questions
How much does an AC tune-up cost in Los Angeles?
A standard AC tune-up in Los Angeles runs $120–$280 depending on system type and condition. A basic split-system tune-up (coil cleaning, refrigerant check, capacitor test, drain clearing) is typically $120–$180. Heavily soiled coils or units that need deeper cleaning run higher. Our $85 service call is waived when you proceed, and you get a flat quote before any work begins.
When should I schedule an AC tune-up?
Spring, before the LA summer heat arrives, is ideal — late March through May. A tune-up before peak season catches a weak capacitor or low refrigerant before it fails on the hottest day of the year, when scheduling is hardest. Annual maintenance also keeps efficiency up and extends compressor life.
Do you handle refrigerant?
Yes. We are EPA Section 608 certified, which is legally required to handle refrigerant. During a tune-up we check system pressures. If the charge is low, that almost always means a leak — we'll locate and explain it rather than just topping off, since topping off a leaking system is wasteful and against best practice.
Will a tune-up lower my energy bill?
Often, yes. Dirty condenser coils are the most common cause of high cooling bills — a coated coil can cut efficiency 20–30%. Cleaning coils, clearing the drain, and confirming proper refrigerant charge restores the system to designed efficiency, which shows up on your bill during heavy-use months.
Do you replace whole AC systems or install central air?
Yes — from tune-ups and repairs to full system replacement projects, we handle it. Call us and we'll coordinate the full scope of work from diagnosis through completion.
What does a tune-up actually include?
Condenser and evaporator coil cleaning, refrigerant pressure check, run capacitor and contactor test, electrical connection inspection, condensate drain clearing and flush, air filter check, blower inspection, and a temperature-split measurement to verify cooling performance. You get a short written summary of findings.
Do you speak Spanish?
Yes. Hablamos español. Our technicians and dispatch are bilingual. Call (213) 205-2055 and request Spanish service, or visit our Spanish-language site at epicstarcor.com/es/.
