Home Maintenance Series: Part 3 – Major Appliances
Buying a home is one of the biggest investments you’ll ever make. Protect that investment with regular maintenance! This is Part 3 of our Home Maintenance Series, where we focus on major appliances in your home. If you missed the previous checklists, check them out here:
HVAC System
Your HVAC system and water heater are the beating heart of your home—keeping you warm in the winter and cool in the summer. The good news? These systems are easy to maintain, and regular care can extend their lifespan significantly. As with any home maintenance, if you are not confident in your ability to safely complete a job, contact the appropriate professional.
Furnace Maintenance
Air Filters
Experts often recommend monthly filter changes, but that depends on your environment. If you live in a dusty area or near construction, you might need to replace them more often. For most homes, quarterly changes work just fine. Pro tip: The least expensive filters work well—particularly if you are planning on changing them more than quarterly anyway.
How to Change a Filter
- Locate the filter: It’s usually behind a thin door on the furnace, but some homes have it behind a metal grill in a hallway or ceiling.
- Check your home inspection report for details if you’re unsure where it is.
- Remove the old filter and simply install a new one, following the airflow direction marked on the side.
- If in doubt, consult your owner’s manual.
Pre-Season Check
Before cold weather hits, turn on your furnace in early fall to make sure everything runs smoothly. A slight burnt dust smell is normal at first and should disappear quickly.
Troubleshooting
- If the furnace isn’t running, check if the pilot light is on (if applicable).
- Ensure the blower switch (a standard light switch near the furnace) is in the ON position. This switch overrides furnace commands, and technicians often turn it off during maintenance.
Condensation on Windows?
High indoor humidity can cause condensation on windows, especially in cold weather. Adjust your humidifier settings and slightly lift the blinds to improve airflow. Wipe condensation away quickly to prevent damage to window sills and drywall. If the issue persists, call an HVAC professional.

Air Conditioning Maintenance
For optimal performance, set your AC to a consistent temperature throughout the day.
Efficiency Tips
- Your system should maintain 78°F indoors or 20°F cooler than the outside temperature.
- Uneven room temperatures? You may need to have your system balanced after installing furniture, blinds, and window treatments. An HVAC technician can help.
Filter Maintenance
- The AC also has a filter that needs to be changed regularly. The filter can be found in the air return vent (they will look larger and slightly different than the air registers found in other rooms). The grill will have a swing-down or sideways door that will allow you to access the filter. You can release the swing-down door using the small plastic or metal tabs on each side.
Preventing AC Drain Clogs
Your AC removes humidity from the air, draining water through two drain lines. These can clog over time, leading to leaks. Have them cleaned annually or DIY with these step-by-step drain cleaning instructions.

Water Heater Maintenance
Keep the Area Clear
Avoid storing anything within three feet of your water heater. This keeps it running efficiently and prevents hazards.
Annual Tank Drainage
Draining your water heater once a year removes sediment buildup, preventing rust, corrosion, and efficiency loss.
Pilot Light (Gas Models)
- Never light the pilot light or turn on electricity if the tank is empty.
- Turn off the cold water supply (usually located at the top of the unit).
- Follow the instructions on the water heater or check the owner’s manual for guidance.
Condensation Drips?
New water heaters may produce slight condensation, which can drip onto the pilot light flame. This is normal and shouldn’t cause any issues.
Tankless Water Heaters
Tankless water heaters require regular maintenance. You should have a professional service it annually for best performance or as recommended by the manufacturer.

Additional Systems to Maintain
Swamp Cooler
Unlike traditional AC units, swamp coolers add moisture to the air to cool your home. They work best in dry areas (hey like Colorado Springs!) You’ll typically see them mounted on the roof or side of a house.
Radiant Heat
Radiant heating comes in two forms: electric or hot water. Older homes may have it in ceilings, while newer ones often have it under tile floors. It’s an efficient, comfortable, and low-maintenance heating option.
Septic Systems
These are common in rural areas or properties over one acre. Some exist within city limits but will need to connect to city sewers when they reach the end of their lifespan.
Wells
If you live on a large lot or in the countryside, your home may have a water well. Regular water testing ensures safe drinking water.
Solar Panels
Solar energy is growing in popularity due to tax incentives, contributing to a greener future, and lower utility bills. Check your system’s user manual for maintenance recommendations.
