It’s unnerving when your HVAC system is in cooling mode and you feel warm air coming from your registers. This can occur for various reasons like a mix-up in basic HVAC settings, neglected routine maintenance, or at worst, a newly-developed problem with the cooling components. Here’s how to identify and solve the most common issues, and know when to call for professional help:
Mix-ups with your thermostat settings can produce warm air output instead of cool, and they’re easily fixed:
If airflow from the registers suddenly goes from cool to warm, there may be a loss of power at the outdoor unit. If it’s non-responsive, check both the outdoor emergency shutoff switch and the unit’s breaker in your home’s main electrical panel. If either has tripped, resetting it may be all that’s necessary. If a reset safety device quickly trips again, leave it alone and call your HVAC pro to determine why.
A drop in airflow through your HVAC system can lead to coil icing and/or a compressor shutdown that leaves you with warm air output when it should be cool. Sometimes, putting in a clean air filter, making sure all the supply and return vents are fully open and unobstructed, and clearing away debris/vegetation that’s blocking airflow at the outdoor unit can help. If there’s no improvement, call your HVAC technician to check for more serious issues, like a low refrigerant charge, a malfunctioning fan, or a dirty evaporator or condenser coil.
