Furnace Maintenance Guide for Merced Winters
March 18, 2026 | Heating Tips
While Merced winters are milder than many parts of the country, temperatures regularly drop into the 30s, and occasional freezes do occur. A well-maintained furnace keeps your family safe and warm while operating at peak efficiency.
Replace the Filter
A clean filter is essential for efficient furnace operation. Check your filter monthly during heating season and replace it at least every 90 days. A dirty filter restricts airflow, forcing your furnace to work harder and increasing energy costs.
Test Your Thermostat
Verify your thermostat responds properly and maintains accurate temperatures. If you have a programmable model, set schedules that lower temperatures when you're asleep or away to save energy.
Check Carbon Monoxide Detectors
Every home with gas heating should have working carbon monoxide detectors on every level. Test them monthly and replace batteries annually. This simple step could save your life.
Clear Vents and Registers
Ensure all supply and return vents are unobstructed by furniture, rugs, or curtains. Blocked vents create pressure imbalances that reduce efficiency and comfort.
Schedule Professional Maintenance
An annual furnace tune-up by a qualified technician includes cleaning burners, checking heat exchangers for cracks, testing safety controls, and verifying proper operation. This preventative service prevents breakdowns and keeps your warranty valid.
