FONTANA
From Sierra Lakes and North Fontana to Southridge and neighborhoods near the I-10, I-15, and SR-210 corridors, homeowners rely on their HVAC systems to stay comfortable through long, hot Inland Empire summers. With temperatures regularly climbing into the 90s and beyond, dependable air conditioning isn’t just about comfort—it’s about keeping your home consistently cool and energy efficient throughout the season.
Homeowner Tip​
​
Before summer arrives, clear leaves, weeds, and debris from around your outdoor condenser. Maintaining at least two feet of open space helps improve airflow and allows your system to cool more efficiently during periods of extreme heat.
Commonly Seen in Fontana Homes
​
Fontana’s long, hot summers place significant demand on air conditioning systems, especially during periods of prolonged triple-digit temperatures. Whether a home is located in an established neighborhood or a newer development, HVAC equipment often works for extended hours to maintain indoor comfort. Over time, that consistent workload can contribute to a variety of common issues.
​
• Air conditioners struggling during prolonged heat ~
During the hottest weeks of summer, it’s common for AC systems to run much longer than usual. While longer run times are expected in extreme temperatures, systems that rarely shut off or have trouble reaching the thermostat setting may be losing efficiency or developing mechanical wear.
• Components wearing out from heavy seasonal use ~
Capacitors, contactors, and fan motors experience added stress after months of continuous operation. These parts often show signs of wear gradually before failing completely, which is why preventative maintenance can help identify problems early.
​
• Dirty condenser coils reducing efficiency ~
Outdoor units naturally collect dust, pollen, and debris throughout the cooling season. When condenser coils become dirty, the system has a harder time releasing heat, causing longer cooling cycles and increased energy use.
​
• Frozen evaporator coils from restricted airflow ~
Restricted airflow caused by clogged filters or blocked vents can sometimes lead to evaporator coils freezing over. Homeowners may notice weaker airflow, reduced cooling, or ice forming on refrigerant lines.
​
• Gradually increasing utility bills ~
One of the earliest signs of an aging HVAC system is often a steady increase in energy costs without any obvious breakdown. Even though the equipment still operates, declining efficiency can cause it to consume more electricity throughout the summer.
