Los Angeles is no stranger to punishing summer heat. Every year, as temperatures spike to extraordinary highs during heatwaves, millions of residents rely on their air conditioners to survive the scorching discomfort. Yet, a common problem resurfaces, leaving many Angelenos frustrated and sweltering in their own homes. AC systems fail just when they’re needed most. But why does this keep happening? From grid strain to inadequate HVAC maintenance, there’s more at play than you might think. That’s why having a contact with a reliable company who focuses on ac repair in Los Angeles.
Heatwaves and Power Strain in Los Angeles
LA’s Heat Dome Effect
Heatwaves in Los Angeles aren’t your average warm summer days. Increasingly, they’re driven by a phenomenon known as the “heat dome.” This occurs when high-pressure systems trap hot air over an area, leading to prolonged periods of intense heat.
According to the National Oceanic and Atmospheric Administration (NOAA), heat domes have become more frequent and severe in Southern California, with temperatures reaching triple digits across the city and surrounding areas. For example, during the 2022 September heatwave, the San Fernando Valley registered 112°F. These extreme temperatures force residents to crank up their AC units, significantly increasing energy demand.
Strain on the Power Grid
The massive uptick in electricity use during heatwaves often overwhelms the local power grid. Data from the Los Angeles Department of Water and Power (LADWP) shows that heatwave-related blackouts affected over 49,505 customers during a single September day in 2022. Many neighborhoods, from Echo Park to Santa Monica, were left powerless for hours or even days.
Air conditioning systems are among the most energy-intensive appliances in your home. When millions of LA residents simultaneously run their ACs at maximum capacity, it places a significant load on the grid, which can cause electrical failures and rolling blackouts. Unfortunately, when blackouts occur, your AC is rendered useless, leaving you at the mercy of the soaring heat.
Your AC System Might Be Part of the Problem
Grid strain is only part of the story. Many homes lose AC during heatwaves because their systems are ill-equipped or improperly maintained to handle the increased workload.
Outdated HVAC Units
Older HVAC units are particularly vulnerable during heatwaves. They often lack the efficiency and capacity to perform optimally under extreme conditions. Additionally, aging systems are more likely to overheat or short-circuit when stressed.
If your AC feels like it’s barely limping along, you’re not alone. Experts estimate that 50% of the air conditioning systems in Los Angeles homes are over 10 years old, a point at which regular wear and tear often lead to breakdowns.
Poor Maintenance Practices
When was the last time you scheduled professional AC maintenance? If you can’t remember, that could be why your system fails during heatwaves. Without regular check-ups, issues like clogged filters, refrigerant leaks, dirty coils, and weak airflow can remain unresolved until they escalate under demanding conditions.
Neglecting routine maintenance leads to your system running inefficiently, requiring more energy and making it prone to failure when it has to work the hardest.
Improper Installation
Even top-of-the-line AC systems can fail if they weren’t installed correctly. Improper installations can cause air leaks, inefficient performance, or even total breakdowns. Ensuring your unit is installed by experienced HVAC professionals can save you headaches when heatwaves strike.
Be Proactive with AC Maintenance
The surest way to keep your home cool and prevent AC failure during heatwaves is by taking a proactive approach to maintenance. Regular servicing, ideally before the peak summer season, is key to maximizing your system’s efficiency and lifespan.
Here’s what regular maintenance should include:
- Filter Replacement: Dirty filters can block airflow and force your AC to work harder, consuming more energy. Replace your filters every 1 to 3 months.
- Coil Cleaning: Condenser and evaporator coils accumulate debris over time, reducing your system’s efficiency. Annual cleaning keeps them in optimal shape.
- Refrigerant Top-Up: Too little refrigerant can result in insufficient cooling. Regular servicing ensures your system always has the correct amount.
- Professional Inspection: Certified technicians can spot issues like worn-out components, loose wiring, or potential leaks before they lead to costly failures.
