DeSoto FAQ

Can I fix warm air blowing from my AC myself?+

Checking the thermostat setting and filter is worth doing yourself first. Refrigerant leaks, compressor issues, and frozen coils need a technician, refrigerant work specifically requires certification and specialized equipment, it's not a DIY repair.

Is warm air from the AC an emergency?+

Not usually a safety emergency, but especially during peak summer heat it's worth addressing quickly rather than letting it go, both for comfort and because some underlying causes (like a frozen coil) can get worse the longer the system keeps running under the same conditions.
