Winter HVAC Failures Start with Clogged Filters
Prepare your HVAC system before winter demand peaks: replace filters, clear vents and outdoor heat pumps, test smoke and carbon monoxide alarms, and inspect for warning signs. Avoid DIY work involving gas, electricity, refrigerant, or combustion. Schedule licensed service, document maintenance, and address unusual noises, icing, weak heat, or unsafe readings promptly.
