Simple Troubleshooting (What to Check First)

Check the Filter

Air filter condition directly impacts every aspect of HVAC performance, from energy efficiency to component longevity. A clogged filter forces the system to work harder, increasing energy consumption while reducing cooling or heating capacity. Monthly filter inspection during peak usage periods prevents most filter-related problems before they affect comfort or cause component damage.

Filter replacement frequency depends on multiple factors including pet ownership, local air quality, and system usage patterns. Standard fiberglass filters typically require monthly replacement, while high-efficiency pleated filters may last up to three months under normal conditions. Bold City Heating & Air recommends establishing a regular replacement schedule based on your specific circumstances rather than relying on generic guidelines.

Visual inspection reveals when filters need replacement - holding the filter up to light shows whether airflow remains adequate. Dark accumulation, visible debris, or inability to see light through the filter material indicates immediate replacement needs. Documenting replacement dates helps establish patterns and optimize replacement intervals for your specific situation.

Verify Thermostat Settings

Thermostat problems often masquerade as system failures when simple adjustments restore normal operation. Verify the thermostat displays the correct mode (heating or cooling) and that temperature settings align with comfort expectations. Dead batteries in digital thermostats cause erratic operation or complete system shutdown, making battery replacement an essential first troubleshooting step.

Programmable and smart thermostats require periodic verification that schedules remain appropriate for current usage patterns. Daylight saving time changes, vacation schedules, or lifestyle changes may require programming updates. Understanding your thermostat's features and settings prevents unnecessary service calls and ensures optimal comfort control.
