Safety first: These guides cover simple homeowner checks only. Stop and call a qualified technician for gas odors, burning smells, repeated breaker trips, refrigerant work, or equipment disassembly.
Spring: Prepare Before the Heat
Replace or inspect the filter, clear leaves and cottonwood fluff from around the outdoor unit, and test cooling before the first very hot day. Keep at least two feet of open space around the condenser and avoid bending its delicate fins.
Summer: Protect Airflow
Check filters more often during wildfire smoke, remodeling, or dusty conditions. Keep blinds closed during peak afternoon sun and avoid drastic thermostat setbacks that force long recovery cycles.
Fall: Test Heat Early
Run the furnace before freezing weather arrives. Confirm carbon monoxide alarms are installed according to manufacturer and local guidance, replace their batteries as needed, and keep combustible storage away from heating equipment.
Winter: Watch for Venting Problems
After storms, visually confirm that accessible exterior intake and exhaust openings are not blocked by snow or debris. Never alter venting yourself. Note unusual odors, soot, repeated shutdowns, or new noises and request service promptly.
- Check filters monthly
- Keep equipment clear
- Test each season early
- Schedule service for persistent noises, odors, or cycling
