Is Your AC Ready for Summer? The Spring Tune-Up Checklist
Every year, West LA homeowners wait until the first heat wave to turn on the AC — and every year, the same systems fail. Here's how to get ahead of it.
The busiest week in West LA HVAC isn't August — it's the first week of real heat, usually mid-June, when every AC unit that sat dormant since October gets switched on at once. Half of them don't work. The other half work but run inefficiently, spiking electricity bills by 30% or more. A spring tune-up costs $89–$149 and prevents both scenarios.
Why Spring Is the Critical Window
Between March and May, HVAC companies operate at roughly 40% capacity. By June, they're fully booked with emergency calls. A spring tune-up means you get same-day or next-day scheduling, your technician isn't rushing between emergencies, and if a major part needs ordering, there's time to get it before you need cooling. In July, that same part order means 3–5 days without AC in 95-degree heat.
The 8-Point Spring AC Checklist
A proper tune-up isn't just 'checking the system.' Here's what should be inspected and serviced: 1. Air filter replacement — a clogged filter reduces airflow by up to 15%, forcing the system to work harder. 2. Refrigerant level check — low refrigerant means weak cooling and eventual compressor damage. 3. Condenser coil cleaning — the outdoor unit collects a year's worth of dust, leaves, and debris. 4. Electrical connections — loose connections cause intermittent failures and are a fire risk. 5. Thermostat calibration — a thermostat reading 3° off means your system runs longer than needed. 6. Drain line flush — clogged condensate drains cause water damage and mold growth. 7. Capacitor test — the #1 part that fails without warning. 8. Ductwork inspection — leaky ducts waste 20–30% of cooled air into attic or wall spaces.
Run your AC for 15 minutes on a mild spring day and check every vent. If any room isn't getting airflow, that's a duct issue — and it's much cheaper to fix now than during peak season.
What a Tune-Up Actually Costs in LA
A standard residential AC tune-up in Los Angeles ranges from $89 to $149 for a single system. Dual-system homes (common in two-story LA properties) run $149–$249. This includes filter replacement, coil cleaning, refrigerant check, and a full electrical inspection. If your technician finds a failing capacitor ($150–$300 to replace) or low refrigerant ($200–$400 to recharge), those are additional — but catching them now prevents a $3,000+ emergency compressor replacement in August.
Signs Your System Needs More Than a Tune-Up
A tune-up maintains a working system. If you notice any of these signs, the conversation shifts from maintenance to repair or replacement: the system is over 15 years old and uses R-22 refrigerant (now phased out and extremely expensive), electricity bills have been climbing year over year even with similar usage, the system short-cycles (turns on and off every few minutes), or you hear grinding, banging, or squealing sounds from the outdoor unit. Any of these warrants a full diagnostic, not just a tune-up.
The best time to service your AC is when you don't need it. The worst time is when everyone in West LA needs theirs fixed at the same time — and every HVAC company has a two-week wait.
