Maintenance & Repair FAQs
Why is my air conditioner running but blowing warm air?
An AC blowing warm air is typically caused by a dirty air filter blocking airflow, a refrigerant leak, or a failing compressor that requires professional diagnostics.
How often should I schedule maintenance for my air conditioning system?
You should schedule professional AC maintenance at least once a year, preferably in the spring, to ensure your system is clean and fully prepared for the Missouri summer heat.
Do you offer emergency AC repair on weekends?
Yes, we provide same-day and emergency air conditioning repairs across the Bootheel, including on weekends and after normal business hours.
Why is there ice on my air conditioner's refrigerant lines?
Ice buildup usually indicates severely restricted airflow from a clogged filter or a low refrigerant charge caused by a leak. Turn the unit off immediately to let it thaw and call for service.
Can routine maintenance help prevent my AC from breaking down?
Yes, routine maintenance removes dirt from the condenser coils and ensures all electrical connections are tight, drastically reducing the chances of an unexpected summer breakdown.
What should I check before calling for an air conditioning repair?
Before calling, verify that your thermostat is set to "cool," ensure the batteries are fresh, and check that your furnace's air filter isn't completely clogged with dirt and debris.
