FURNACE BLOWING COLD AIR IN ROLLING HILLS

A furnace that blows cold air isn't completing the heating cycle, leaving your home cold despite the system running. Rolling Hills homeowners experience this issue at a rate roughly proportional to housing age and climate exposure — older Rolling Hills homes (built before 1985) have a notably higher incidence than newer construction.

Rolling Hills experiences a unique microclimate influenced by its proximity to the coast and the marine layer that often rolls in from the Pacific Ocean. This results in cooler evenings but can create a significant temperature differential between day and night, which HVAC systems must account for. The warm summer months may lead to increased demand for cooling, making it vital for residents to have well-maintained systems that can adapt to these changing conditions. For cold air specifically, this matters because the climate determines how hard your system is being pushed when the failure occurs.

Before calling us, you can try the following DIY checks — many Rolling Hills homeowners resolve the issue themselves without a service call:

• Verify thermostat is set to HEAT and AUTO (not FAN)
• Check that set temperature is above room temperature
• Replace dirty air filter
• Look for flashing error codes
• Ensure gas valve is on
