Once the sun sets, many Los Angeles homeowners assume their air conditioner should run smoothly without added strain. As outdoor temperatures drop and the sun sets, the house should naturally cool down and feel more comfortable after a hot day. So why does your AC seem to run longer at night than it did during the day?
Our team at JMS Air Conditioning and Heating has helped homeowners across Los Angeles solve this frustrating problem since 1993. We find the issue isn’t necessarily the nighttime temperature at all. It’s how your home holds onto heat after the sun goes down. Here’s what to know and how to get your AC system back on track.
Your Home Is Still Releasing Heat
Even after sunset, your home continues to release heat that has accumulated throughout the day. Roofing materials, attic spaces, exterior walls, concrete patios, and even garages can all store heat for hours before slowly transferring it indoors. This kind of heat release is especially common in Los Angeles after hot and sunny afternoons. Your AC may actually be fighting yesterday’s heat rather than today’s.
Your Thermostat May Take Time to Reach the Temperature You Want
It’s normal to want to keep an eye on your energy bills, raise your thermostat while you’re at work, and lower it before bedtime. That evening temperature change often requires your system to cool the entire home several degrees all at once. Even if it’s cooler outside, lowering the thermostat from 78 to 70 degrees means the AC system has to remove a significant amount of heat. The result is a longer cooling cycle before bedtime, which can make your home feel uncomfortably warm.
High Indoor Humidity Can Make Rooms Feel Warmer
Los Angeles isn’t known for its extreme humidity, but coastal neighborhoods and certain summer weather patterns can make indoor air feel damp. Even a small amount of humidity makes it harder for sweat to evaporate, making rooms feel warmer than the thermostat reading suggests. An overlooked contributor is running exhaust fans continuously after showering or cooking. If replacement air leaks into the home from outdoors overnight, your AC could be working overtime to cool and dehumidify that incoming air before your home feels comfortable again.
An Aging AC System Can Struggle During Peak Demand
If your AC is older, has a refrigerant leak, has a dirty filter or coils, or hasn’t received regular maintenance, it may struggle even more to keep your home comfortable at night. It’s not uncommon for systems to struggle to recover and cool efficiently after a hot Los Angeles day. Routine AC maintenance helps keep airflow going strong, improves efficiency, and catches small issues before they become expensive repairs.
