Why Seasonal HVAC Maintenance Matters
Prevents Unexpected Breakdowns
Routine maintenance minimizes the risk of sudden malfunctions, especially during extreme cold spells. Proactively addressing issues keeps your HVAC system running when you need it most.
Improves Efficiency and Reduces Energy Bills
A clean, tuned-up system uses less energy, reducing monthly bills. According to the U.S. Department of Energy, seasonal HVAC maintenance can improve system efficiency by up to 22%.
Prolongs System Lifespan
HVAC systems are a long-term investment. Regular maintenance protects your system from wear and tear, extending its lifespan and delaying costly replacements.
Ensures Indoor Comfort and Air Quality
A well-maintained HVAC system maintains even temperatures and reduces dust, pollen, and other allergens. This improves indoor air quality, making your home a healthier place.
Winter HVAC Maintenance Tasks to Complete in Southwest Iowa
This section offers a simple maintenance guide. It includes weekly tasks that begin four weeks before winter starts.
Four Weeks Before Winter: Preliminary Checks
- Inspect Your Heating System’s Components
- Thermostat Check: Test your thermostat for accuracy by setting a temperature and observing if it maintains the set point.
- Safety Equipment: Ensure smoke and carbon monoxide detectors are functional. Replace batteries as needed.
- Filter Inspection: Replace air filters to maintain airflow and reduce strain on your system. Schedule a filter replacement with John’s Heating & AC.
- Clear Outdoor Units and Ducts
- Remove leaves, dirt, and debris around outdoor units to prevent airflow obstruction.
- Dust and vacuum air ducts and registers to improve indoor air quality and system efficiency. Book a duct cleaning service.
Three Weeks Before Winter: Optimizing Efficiency
- Seal and Insulate
- Seal gaps around doors, windows, and attic spaces to prevent heat loss.
- Insulate exposed pipes and ducts to reduce energy waste. Learn about insulation services.
- Schedule a Professional HVAC Inspection
- Book an inspection to ensure all components are in top condition. This is especially crucial for preventing breakdowns in winter.
Two Weeks Before Winter: Detailed System Checks
- Examine the Furnace and Heat Exchanger
- Inspect the furnace and heat exchanger for cracks, dust, or soot. Clean these areas to maximize heating efficiency.
- Check Ductwork for Leaks
- Perform a quick check for visible tears or loose connections in ducts. Leaky ducts increase energy waste. Schedule duct inspection.
