A furnace plays a critical role in maintaining home comfort during cold weather, yet it is often neglected until problems arise. Routine preventive maintenance not only reduces unexpected breakdowns but also helps the system operate efficiently and last longer. Homeowners who understand the importance of care can avoid costly repairs and improve energy savings. Furnace maintenance checklist homeowners should know Furnace maintenance checklist 1. Replace Air Filters Regularly Clogged filters restrict airflow, forcing the furnace to work harder than necessary. Replacing filters every one to three months keeps the system efficient and ensures cleaner indoor air. A fresh filter also reduces strain on the blower motor, extending the unit’s life. 2. Inspect the Thermostat A malfunctioning thermostat leads to uneven heating or unnecessary energy use. Check that settings are accurate and test responsiveness by adjusting temperatures slightly. Upgrading to a programmable or smart thermostat fur...
A running condenser fan with a silent compressor can confuse and frustrate homeowners. The outdoor fan blades spinning might give the impression the system works fine, yet the air remains warm indoors. Understanding what causes this mismatch will help identify solutions faster and avoid serious system damage. Fan Works, Compressor Doesn’t? Common Causes AC Compressor Failure Signs When Fan Still Works Faulty Capacitor The most common reasons a compressor doesn't engage is a failed capacitor. The capacitor stores and delivers a quick burst of energy to start the compressor and fan motors. A defective capacitor may still let the fan spin but fail to jump-start the compressor. Replacing the capacitor typically restores normal function. Burned-Out Compressor Compressors deal with high pressure and electrical loads. Over time, stress or overheating can lead to burnout. A burned-out compressor won't make noise or activate, even though the fan keeps running. Replacement becomes necess...
