HVAC MAKING STRANGE NOISES IN ROLLING HILLS

Unusual sounds from your HVAC system often indicate mechanical issues that can worsen if ignored. Different sounds point to different problems. 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 strange noises 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:

• Identify when and where the noise occurs
• Check for loose vent covers or grilles
• Ensure air filter isn't clogged
• Look for visible loose panels on unit
• Note if noise changes with fan speed
