Common Questions
Why does my AC keep shutting off or blowing warm air, especially during an O Fallon summer?
A common culprit in our area is a failing AC capacitor. This critical component helps start and run your outdoor unit's compressor and fan motor. When it weakens or fails, your system can't maintain proper operation, leading to shutdowns or warm air. Taff Sales can quickly diagnose and replace a faulty capacitor to restore your cool air.
How can I tell if my HVAC system is the wrong size for my O Fallon home?
Signs include frequent on/off cycling (short-cycling), inconsistent temperatures from room to room, excessive humidity indoors, and unusually high energy bills. An improperly sized system struggles to heat or cool your space efficiently. Our experts at Taff Sales perform detailed load calculations to ensure any new installation is perfectly matched to your home's specific needs.
What are the risks of just replacing a failed part like a capacitor without a full system check?
While replacing a single failed part can be a fix, it might not address the root cause. For instance, a failing capacitor can sometimes be a symptom of other electrical issues or an overworked system. Our thorough diagnostic approach ensures we identify any underlying problems, preventing future breakdowns and protecting your overall HVAC investment.
