While you can expect your HVAC system to function without trouble for years to come, occasional problems can occur even with well-maintained systems. Knowing how to troubleshoot some of the most common heating and cooling problems can help you save time and money when it comes to restoring comfort at home. If you encounter a problem you can’t diagnose or solve yourself, your Columbia HVAC service can provide the prompt and effective repairs you need at any time of year.

System Won’t Activate
If your furnace or air conditioner won’t activate, there are a few possible causes you should investigate. First, make sure your thermostat is set properly, such that your desired air temperature is above (for heating) or below (for cooling) the ambient temperature reading. Additionally, check your circuit breaker or fuse box to ensure the system is receiving the power it needs to run. If your furnace or air conditioner has an obvious reset button, try using it to reset the system and prompt it to activate. Similarly, if your HVAC appliances draw current via a wall plug, make sure the appliance is plugged into an outlet that is receiving power and that the cord is in good shape. If you still can’t determine the cause of your problem, contact an HVAC technician for an evaluation.

Ice on Your Air Conditioner

Ice formation on air conditioning coils is a common summertime problem. The most likely cause of this issue is a dirty furnace filter, which restricts airflow through the unit and causes ice to form. Replacing your furnace filter, particularly if it hasn’t been replaced in the past month, could solve your problem. Alternatively, dirty evaporator coils may be causing ice to build up—handy homeowners can try cleaning the coils themselves, or you can contact your HVAC service to perform this cleaning for you. If changing the air filter and cleaning the coils yourself doesn’t work, it’s time to call in a professional for assistance. Your air conditioner may need additional attention or a refrigerant recharge to restore proper cooling and prevent ice formation.

Uneven Heating and Cooling

Uneven heating and cooling are typically due to either a problem with your furnace blower motor or your ductwork and vents. First, check that your vents are open in areas where you want heated or cooled air; you should also make sure that your vents and air registers aren’t blocked by furniture, window treatments, or other items. Second, try using your vacuum’s hose attachment to clean out your vents and vent covers, as dust and debris buildup could block airflow and affect your indoor comfort. If you’re still experiencing uneven heating and cooling, talk to your HVAC service about a duct inspection and duct cleaning to address leaky ducts or remove debris that could be clogging your ductwork and preventing proper airflow. You may also wish to consider HVAC zoning, which uses multiple thermostats to regulate the temperature more effectively in various areas of your home.
