Trusted HVAC Repair in Olivette, MO 63132 - Havis Lee HVAC

That's a classic sign of a failing AC capacitor, a very common issue we see in Olivette homes. The capacitor helps start your outdoor unit's compressor and fan motor. When it weakens, the unit struggles to start and may short cycle (turn on/off rapidly). This not only compromises your comfort but can damage the compressor. We can quickly test and replace a faulty capacitor to restore proper operation and prevent more costly repairs.

Thermostat problems are frequent here and can stem from several causes. It could be incorrect calibration, old age, faulty wiring, or even a tripped breaker. Before you buy a new one, it's wise to have a professional diagnose the issue. We'll check the wiring at the thermostat and at your HVAC unit, ensure it's receiving power, and test its accuracy. Often, a repair or recalibration is all that's needed, saving you the cost of an unnecessary replacement.

For a reliable summer in Olivette, we recommend addressing two key areas: capacitor health and thermostat function. A weak capacitor is the leading cause of sudden AC breakdowns on the first hot day. Secondly, an inaccurate or malfunctioning thermostat will make your system run inefficiently, raising bills and straining components. Scheduling a pre-season tune-up with Havis Lee HVAC includes checking these critical parts, cleaning your system, and ensuring everything is ready for the St. Louis heat, preventing inconvenient and expensive emergency repairs.
