First Clues
You set the thermostat to cool, but the air from the vents feels warm or only slightly cool. Sometimes the system runs nonstop without lowering the temperature much. That is a common summer problem for homeowners in Longmont and Boulder County.
Likely Reasons
The issue could be a thermostat setting, a dirty air filter, low refrigerant, or a problem with the outdoor unit. A blocked condenser coil or a tripped breaker can also keep the system from cooling properly. If the fan runs but the air stays warm, the problem is usually inside the AC system itself.
Best Next Steps
Check the thermostat mode, replace a clogged filter, and look outside to see whether the condenser is running and clear of debris. If the AC still blows warm air, stop trying to force it to run and schedule a diagnostic visit.
