Troubleshooting Your HVAC System

Your HVAC system is responsible for maintaining a comfortable indoor environment, regardless of whether the season calls for heating or air conditioning. Although regular maintenance should keep your heater and air conditioner functioning problem-free for years to come, problems can still occur as parts wear out or dust and dirt accumulate over time. By learning the most common HVAC issues faced by homeowners today, you can learn to spot the symptoms of trouble brewing and take steps to head it off to prevent breakdowns that affect your comfort in Myrtle Beach.

Power Issues

If your furnace or air conditioner won’t turn on, the first place to look is your circuit breaker. A tripped circuit means your HVAC system has been trying to draw more power than your home’s electrical system can handle. If your circuit breaker appears fine, check that your furnace or air conditioner is plugged completely into an outlet that is receiving power and that the power cord is in good condition. Older outlets may lose contact with the plug, while a frayed or damaged cord won’t transfer power properly. If you still can’t get your system to turn on, it may be a problem with a contactor or capacitor within the appliance; you’ll need to contact your HVAC service for help.

Pilot Light and Gas Valve Problems

Gas furnaces often use a pilot light to activate the burner system. If you’re experiencing a heating problem, check the pilot light on your furnace by finding the gas line running into the appliance and remove any panels necessary to access the pilot light and burner assembly. Check the gas valve near the pilot light; these valves can corrode over time, affecting the flow of gas and causing the pilot light to go out. A corroded valve will need to be replaced to restore consistent heating for your home. If the valve appears intact, you can try re-lighting the pilot light by following the manufacturer’s instructions for your furnace. When re-lighting a pilot light, always perform a safety check first by turning the gas off completely and waiting five to ten minutes before re-lighting the pilot light. If you smell gas, don’t try lighting the pilot light—call your HVAC service instead.

Frozen Evaporator Coil

A clogged or dirty evaporator coil can cause ice to build up on your air conditioner, affecting its cooling ability. If you find ice on your air conditioner coils, first thaw out the coils by turning your air conditioner off and letting the ice melt—you may want to place a bucket beneath the coils to catch the runoff. Once the ice has melted, turn your thermostat up and set the fan to “run” so it can blow warm air through the coils and clear out any remaining ice or debris. Now is also a good time to change your furnace filter, as a clogged filter is often the cause of dirty evaporator coils. After you’ve run the fan on your air conditioner for a few minutes, you can resume cooling your home as normal. If you’re still experiencing ice buildup, you may have a refrigerant leak—call in your HVAC service to clean your air conditioner and check your refrigerant levels.
