The cooler months in Hesperia, Victorville, and across San Bernardino County can bring noticeable temperature dips, and nothing disrupts your comfort faster than a malfunctioning furnace or heat pump. While complex repairs always require a certified professional, there are several simple troubleshooting steps you can take before calling the experts at West Country HVAC. Taking a moment to check these common issues can often save you time and restore warmth to your home right away.
Simple Checks: Starting with the Basics
Before diving into complex diagnostics, start with the most basic checks, which often resolve the majority of heating calls we receive.
Check Your Thermostat Settings
This might seem obvious, but it is the number one overlooked issue. Ensure your thermostat is set to "Heat" and that the temperature is set above the current room temperature. Also, check that the fan is set to "Auto" instead of "On"; leaving it on "On" will cause the fan to run constantly, potentially blowing cool air when the furnace isn't actively heating. If you have a smart or programmable thermostat, confirm the current schedule isn't keeping the heat off.
Confirm the Power Switch and Breaker
Always confirm your unit is receiving power before assuming a major malfunction. Ensure the furnace's power switch (often found near the unit) is securely in the ON position. Next, check your main electrical breaker panel for the HVAC system's labeled breaker and make sure it is ON. Safety Note: If the breaker immediately trips again after resetting, call West Country HVAC immediately, as this signals an an electrical fault within the unit.
Airflow Issues: The Filter and Vents
Poor airflow is a major cause of heating inefficiency and breakdowns, especially in our high desert climate where dust accumulation is frequent.
Change the Air Filter
A clogged air filter is the most common reason for poor heating performance. A dirty filter restricts airflow, forcing your furnace to work harder and often causing it to overheat and shut down prematurely. Given Hesperia's arid conditions, check your filter monthly and replace it every 1 to 3 months for optimal system health, efficiency, and indoor air quality.
Check All Vents and Registers
Good airflow depends on clear pathways throughout your home. Walk through your home and ensure that all air vents and return registers are open and completely unobstructed. Blocking even a few vents with furniture or drapes can negatively affect your system's pressure balance, leading to inefficiencies and potential damage.
Fuel and Ignition: If You Smell Gas or Hear Nothing
If you have a gas furnace, be mindful of fuel and ignition indicators. Safety First: If you notice a strong smell of gas, immediately leave your home and contact your utility provider from a safe location. If your system is completely non-responsive after the initial checks, the issue is likely with the ignition system (pilot light or electronic igniter). For safety, issues involving electronic ignition components should only be handled by a certified technician.
