HVAC Services Ballwin MO | Call Pfeiffer Heating & Cooling

First, check the basics: ensure it's set to 'heat' or 'cool' correctly, replace the batteries, and verify the circuit breaker hasn't tripped. If problems persist, it could be faulty wiring, a sensor issue, or the unit needing calibration—common issues we see in local homes. Our technicians can diagnose and repair or recommend an upgrade to a more reliable model.

We recommend checking your filter monthly and changing it at least every 90 days. In Ballwin, with our seasonal pollen and dust, homes with pets or higher occupancy might need changes every 30-60 days. A clogged filter is a frequent cause of poor airflow, strain on your system, and higher utility bills. We can advise on the best filter type for your specific HVAC system.

Watch for uneven heating or cooling, strange noises, frequent cycling on/off, rising energy costs, or weak airflow. These are often symptoms of underlying issues like those we commonly fix. Regular professional maintenance from our team can catch small problems early, improve efficiency, and extend your system's life, saving you money and hassle.
