Winter HVAC Maintenance Checklist for Johnson County Homes
Winters in Johnson County, KS can be unpredictable — sunny one day and freezing the next. Don’t let your heating system catch you off guard. This guide covers the most important steps to prepare your furnace and HVAC system for winter so your home stays warm and efficient.
1. Replace or Clean the Air Filter
This simple step improves airflow, protects your system, and keeps indoor air clean. For most homes, filters should be changed every 1–3 months — especially before winter hits.
2. Test the Thermostat
Switch your thermostat from cooling to heating and raise the temperature. If your furnace doesn’t kick on or feels weak, it may need service. Consider upgrading to a smart thermostat to program winter settings and reduce waste.
3. Schedule a Seasonal Furnace Tune-Up
Professional inspections can detect problems like:
- Cracked heat exchangers
- Faulty ignition systems
- Carbon monoxide leaks

4. Seal Leaks Around Doors and Windows
Drafts can make your HVAC system work harder. Add weather stripping or caulk gaps to prevent heat loss — especially in older homes in Leawood, Prairie Village, and Lenexa.
5. Check Carbon Monoxide Detectors
Furnaces can leak carbon monoxide if the heat exchanger is cracked. Test CO detectors and replace batteries at the start of each heating season.
6. Clear Air Vents and Ducts
Make sure furniture isn’t blocking your supply or return vents. If you haven’t had your ductwork inspected in 3+ years, consider a cleaning or ductwork repair to restore airflow and balance.
7. Insulate Exposed Pipes and Ducts
Use foam pipe insulation in unheated basements or crawl spaces. Insulated ductwork in attics or garages helps reduce energy waste and system strain during cold snaps.
8. Set Up a Maintenance Plan
A year-round HVAC maintenance plan saves money and ensures your system is inspected before each major season — including winter prep and spring cooling checks.
