Should I Have a Spring AC Performance Check?

Most West LA homeowners don’t think much about their air conditioner until they need it, and that’s understandable. When the weather is mild, the system isn’t exactly top of mind. But the first real heatwave of the summer has a way of arriving quickly, and when it does, HVAC service schedules fill up just as fast.

A pre-season AC performance check is the simplest way to get ahead of that. Having your system looked at in May, before temperatures climb and before every other homeowner in the neighborhood is calling for the same appointment, puts you in a much better position heading into summer. Here’s why the timing matters and what a proper check actually involves.

Benefits of Scheduling HVAC Annual Maintenance for Late Spring

Timing an AC performance check for late spring isn’t just about convenience, though that’s part of it. It’s also about giving yourself options.

If a technician finds a worn capacitor, a refrigerant issue, or a blower motor that’s starting to show its age, a May appointment gives you time to address it without pressure. You can order parts, schedule repairs, and get your system back in shape before it’s needed.

By mid-July, that same repair becomes an emergency. Lead times on parts get longer when demand spikes, service appointments get harder to book, and, in the meantime, you’re waiting out a heatwave with an AC that isn’t working the way it should.

The other factor is system stress. Air conditioners that sit mostly idle through a mild Los Angeles winter and then switch abruptly to heavy use in summer are more likely to surface problems early in the season than systems that have been recently inspected. A performance check before that transition is the most reliable way to find out where things stand before the system is under real load.

What an AC Performance Check Covers

A thorough pre-season AC maintenance visit covers the components that most directly affect whether your system runs reliably when temperatures climb.

1. Refrigerant Level Inspection

Low refrigerant reduces cooling capacity and puts added strain on the compressor. Because refrigerant doesn’t deplete under normal conditions, a low charge typically points to a leak that’s worth identifying and addressing before the system runs hard all summer.

2. Electrical Components and Controls

Capacitors, contactors, and wiring connections are among the more common failure points in aging systems. Testing these components during a performance check catches the kind of gradual degradation that doesn’t always show up as an obvious symptom until something stops working entirely.

3. Coil Cleaning

Both the evaporator and condenser coils accumulate dust and debris over time. Dirty coils reduce the system’s ability to transfer heat efficiently, which means longer run times, higher energy use, and more strain on the equipment. Cleaning them restores the performance the system was designed to deliver.

4. Blower Motor and Airflow Assessment

Weak or uneven airflow is one of the more common complaints during the first hot stretch of summer. A performance check includes inspecting the blower motor, verifying airflow is balanced across the home, and confirming that nothing is restricting circulation through the system.

5. Condensate Drain Cleaning

A clogged condensate drain line can cause water to back up into the system or surrounding areas. It’s a straightforward issue to address during a maintenance visit and an easy one to overlook until it becomes a problem.

6. Thermostat Verification

A thermostat that’s reading temperatures inaccurately or responding sluggishly can make an otherwise functional system feel like it isn’t keeping up. Verifying calibration and responsiveness is a simple step that’s easy to skip and worth including.

What It Won’t Tell You

An AC maintenance check gives you a reliable picture of where your system stands at the time of the visit. It doesn’t guarantee the system won’t develop an issue later in the season, but it does significantly reduce the likelihood of a surprise. 

Most mid-season breakdowns trace back to components that were already showing signs of wear. A thorough inspection catches the majority of those before they become failures, which is about as much certainty as any mechanical system can offer.

Is AC Maintenance Worth It If the Unit Seems Fine?

This is probably the most common reason homeowners put off HVAC annual maintenance: the system ran fine last summer, so why spend money on a checkup now?

The honest answer is that air conditioning systems tend to run fine right up until they don’t. The components most likely to cause a mid-season failure, including capacitors, contactors, and refrigerant charge, don’t usually announce themselves before they go. A system that cooled your home without issue last August may have components that are one hot afternoon away from giving out.

For most homeowners, the cost of a pre-season air conditioning service is considerably less than an emergency repair call, and significantly less disruptive than waiting several days for a technician during peak season.

Schedule Your AC Performance Check Before Summer Arrives

If your system hasn’t been looked at since last year, late spring is a good time to change that. Brody Pennell Heating & Air Conditioning provides thorough pre-season AC maintenance for Los Angeles homeowners who’d rather spend July staying cool than waiting on a repair.
