Winter Home Maintenance Checklist: 7 Must-Do Steps for Des Moines & Grimes Homes

Freezing temperatures, snow, ice, and winter storms put heating, plumbing, and safety systems to the test across Central Iowa. A winter home maintenance checklist helps you find problems before the first deep freeze leaves you without heat or causes frozen pipes and water damage.

Use these seven steps to prepare your home for winter in Grimes, Des Moines, and surrounding communities.

1. Schedule Furnace or Heat Pump Maintenance

Start Iowa winter maintenance with your heating system. A pre-season inspection gives a technician time to find worn parts, airflow problems, thermostat issues, and safety concerns before temperatures plunge.

Professional heating maintenance includes testing system operation, checking airflow and controls, inspecting components, and cleaning equipment as needed. Greens Appliance, Heating & Cooling has NATE-certified technicians who service furnaces and heat pumps throughout Central Iowa.

2. Change Filters and Clear Airflow

Check your HVAC filter monthly during periods of heavy winter use. Replace a dirty filter according to its condition and the manufacturer's instructions. A clogged filter restricts airflow and makes the heating system work harder to move warm air throughout the home.

Keep supply vents and return grilles open and unobstructed. Furniture, rugs, boxes, and other household items blocking airflow interfere with heating distribution.

3. Protect Pipes and Flush the Water Heater

Frozen pipe prevention starts before temperatures drop. Disconnect outdoor hoses, protect vulnerable water lines, and winterize outdoor faucets as required for your plumbing setup. Pay particular attention to pipes in unheated or poorly insulated areas.

Your water heater also works through the winter to meet daily hot-water demand. Sediment accumulating inside the tank interferes with heating and takes up space. Water heater maintenance includes flushing and other system checks based on the equipment and its maintenance requirements. Keeping the water heater on a regular service schedule helps address buildup before it affects operation.

4. Fix Dry Winter Air

Central Iowa winters bring dry indoor air once heating systems begin running regularly. Static electricity, dry skin, irritated noses and throats, and shrinking or cracking woodwork are common signs of low indoor humidity.

Whole-home humidifiers add controlled moisture to air through the HVAC system instead of treating individual rooms. An indoor air quality evaluation helps determine current humidity levels and identify the equipment that fits the home's needs.

5. Prep for Storms and Outages: Iowa's “Big Three”

Winter storms and ice create more than a heating concern. Before severe weather arrives, check the readiness of three important home systems: the whole-home generator, surge protection, and sump pump backup.

Follow manufacturer instructions for routine generator and backup-system checks. Confirm that sump pump backup equipment is ready for an outage and keep emergency supplies available when snow or ice makes travel difficult. Whole-home surge protection helps protect connected electrical equipment from voltage spikes associated with utility disruptions and power restoration.

6. Clear Outdoor Units and Test Detectors

Keep heat pump outdoor units clear of leaves, snow, and ice so air moves freely through the equipment. Check exterior furnace vents and exhaust openings after snowfall to make sure they remain unobstructed.

Test smoke and carbon monoxide detectors before the heating season and replace batteries as required. These devices are especially important when fuel-burning heating equipment operates regularly through the winter.

7. Put Winter Care on a Yearly Schedule

Winter home maintenance becomes easier when recurring tasks stay on a yearly schedule. Track HVAC tune-ups, filter checks, water heater service, detector testing, and other seasonal work instead of waiting for equipment trouble.

Greens Priority Maintenance gives homeowners a way to stay on top of recurring home-system care. Keeping maintenance records also makes it easier to see what has been completed and what is due before the next winter season.
