Peak Summer HVAC Strain: Components Most Likely to Fail During California Heatwaves

July 11, 2026

When a California heatwave settles into Burbank, your HVAC system may run for long stretches with very little downtime. That extra demand can expose weak parts, reduce cooling performance, and increase the risk of a breakdown when you need comfort the most. Why Heatwaves Put Extra Stress On HVAC Systems During extreme summer temperatures, your AC has to remove more heat from the home while also dealing with hotter outdoor air around the condenser. If the system is older, dirty, low on refrigerant, or already struggling with airflow, the added strain can push key components closer to failure. Homes with direct sun exposure, poor insulation, or blocked vents may also place more demand on the system. Even a well-maintained unit can work harder during peak heat, which is why seasonal service is so important before temperatures climb. Capacitors And Contactors Capacitors help motors start and run properly, while contactors help control power to the outdoor unit. Both parts are under heavy electrical stress during long cooling cycles. When they weaken, the system may hum, struggle to start, shut off unexpectedly, or fail to turn on at all. Because these parts are common failure points during hot weather, unusual startup issues...

Why Your AC Runs Longer During California’s Marine Layer (May Gray)

May 1, 2026

May Gray in Southern California brings cooler mornings, overcast skies, and a break from direct heat. On paper, that should mean less demand on your system. Yet many homeowners in Burbank notice the opposite. Their AC seems to run longer, even when temperatures are lower. The reason comes down to how your system responds to moisture, airflow, and indoor comfort. Cooler Air Does Not Always Mean Less Work During the marine layer, outdoor temperatures drop, but humidity levels rise. Your system is not just cooling air. It is also pulling moisture out of it. That process takes time. Instead of short, powerful cooling cycles, your system may run longer to gradually remove humidity while maintaining the set temperature. The air may already be cool, but until the moisture is reduced, it does not feel comfortable inside. Humidity Changes How Your Home Feels When indoor humidity climbs, the air starts to feel heavier. Even at the same temperature, it can feel warmer than it actually is. This is where many homeowners make a costly mistake. They lower the thermostat to compensate. The cooling system responds by running longer, not because the house is hot, but because it is trying to hit...

Spring HVAC Prep for California Homes: Preventing Pollen Build-Up in Hard-to-Reach Areas

March 2, 2026

Spring in Burbank brings warmer afternoons, blooming trees, and a noticeable increase in airborne pollen. While most homeowners think about dusting surfaces and changing air filters, pollen often settles in places you cannot easily see. Inside your heating and cooling system, buildup can quietly affect airflow, efficiency, and indoor air quality. Preparing your system for spring means looking beyond the obvious. Why Pollen Accumulates Inside Your System Your HVAC system constantly circulates air throughout your home. As outdoor pollen levels rise, those particles enter through open doors, windows, and even small gaps in your home’s structure. Once inside, pollen can collect in return ducts, on blower components, and along evaporator coils. Over time, this buildup may restrict airflow and cause your system to work harder than necessary. It can also recirculate allergens back into living spaces. Upgrade And Monitor Your Air Filtration Spring is the ideal time to review your filter choice. Standard filters may not capture finer pollen particles effectively. Selecting a filter with an appropriate MERV rating for your system can improve capture rates without restricting airflow. It is also important to check filters more frequently during peak pollen months in Burbank. Even a high quality filter loses...

How Do I Know if I Have a Heat Pump?

December 13, 2024

Understanding what type of heating and cooling system you have in your home is essential for proper maintenance and efficiency. If you’re unsure whether you have a heat pump, you’re not alone. Many homeowners aren’t familiar with the specific type of system they’re using. Here’s how to tell if your system is a heat pump and what makes it unique. Look at Your Outdoor Unit A heat pump often looks very similar to a standard air conditioner from the outside, which can cause confusion. However, a heat pump is capable of providing both heating and cooling, while an air conditioner only cools. To check if your system is a heat pump, look at the outdoor unit while your home is being heated. If the outdoor unit is running during heating mode, you likely have a heat pump. Check the Labels or Manual The manufacturer’s label or your system’s user manual can provide valuable insight. Most heat pumps will have a label or a model number that identifies them as a heat pump. Search for terms like “heat pump” or a model number that you can reference online. If you have trouble locating this information, your thermostat may also provide a...
