How to Know When Your Heater Needs Service

Keep an eye out for warning signs that your commercial or residential heating system may need professional attention. If you see unexpected spikes in energy bills, unusual noises like banging or whistling, a yellow pilot light (which could indicate a carbon monoxide issue), uneven room temperatures, or weak airflow, they are all indicators that service is needed. Early maintenance or repairs can prevent full system failures and costly replacements, especially with older units. Dennis's Heating & Cooling provides expert heating & air conditioning repair and maintenance in San Francisco for all makes and models, including Carrier, Trane, Bosch, Lennox, Rheem/Ruud, Goodman, Amana, Bryant, Mitsubishi, Daikin, LG, and more.
