Appliance, Air Conditioning, and Heating Repair | Emergency HVAC Services in Saint Louis, MO

Yes, a sudden loss of cooling, especially during our hot, humid summers, is often caused by a failed AC capacitor. This common component helps start the compressor and fan motors. We can diagnose and replace it quickly to restore your comfort and prevent further system strain.

Older homes often have accumulated dust and allergens. We recommend starting with a professional duct cleaning to remove debris from your system. Upgrading to a higher MERV-rated air filter and considering adding a UV light or whole-house air purifier can significantly reduce pollutants, allergens, and humidity for healthier indoor air.

The single most important task is scheduling bi-annual professional tune-ups—once for your AC before summer and once for your heater before winter. This preventative check catches small issues (like weak capacitors or dirty coils) before they become major, costly repairs and ensures your system runs safely and efficiently through our extreme seasons.
