Why Is My AC Blowing Warm Air? Common Causes: A PlanoHomeowner's Guide

Plano calls on this topic aren't unusual for us, especially from homes near Collin County. Here's the short version of what we'd tell you on-site.

For Plano Homeowners

Between established neighborhoods and newer construction, Plano has enough variety in home age and system type that we rarely assume anything about a system before actually looking at it.

Plano, home to Plano ISD, is one of the larger cities in the Metroplex, with a wide mix of home ages, from established neighborhoods built decades ago to newer construction near the city's corporate corridor. That range means we see everything from older systems due for an honest repair-versus-replacement conversation to newer high-efficiency installs.

Plano 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.

Does this apply to homes in Plano specifically?+

Yes. The guidance in this article applies to residential HVAC systems throughout Plano and the rest of our service area. If you want a read on your specific system, call us at (817) 935-8540 or request an estimate and mention you're in Plano.
