Debunking a Common Heating Myth
One of the most persistent myths we encounter at Sentry Heating is that furnaces need annual refrigerant charging, similar to air conditioning units. This misconception costs homeowners unnecessary money and worry each year.
Let’s set the record straight:
Why Furnaces Don’t Use Refrigerant
• Furnaces heat your home through combustion or electrical resistance
• Only heat pumps and air conditioners use refrigerant
• Furnaces circulate heated air, not cooled air
• No refrigerant means no need for recharging
What Your Furnace Actually Needs
Instead of refrigerant service, your furnace requires:
• Regular filter changes
• Annual safety inspections
• Combustion chamber cleaning
• Blower motor maintenance
Understanding this difference can save you hundreds of dollars in unnecessary service calls. While professional maintenance is crucial for your heating system, knowing what your specific equipment needs helps you make informed decisions about your home comfort.
If you’re in Vestavia Hills, Hoover, or surrounding areas, our team at Sentry Heating can help you understand exactly what maintenance your heating system requires for optimal performance and longevity.
