Winter in Wichita, KS can put serious strain on your home’s heating system, especially during periods of freezing temperatures and high energy demand. When your HVAC system is working overtime, skipping routine maintenance can lead to reduced efficiency, higher utility bills, and unexpected breakdowns at the worst possible time. That’s why taking care of a few key maintenance tasks before and during winter is so important for local homeowners.
From furnace inspections and filter changes to airflow checks and thermostat calibration, winter HVAC maintenance plays a critical role in keeping your home warm, safe, and energy efficient. In this guide, the experts at Fenix Heating & Cooling highlight the top winter HVAC maintenance tasks you shouldn’t ignore — and explain how staying proactive can help you avoid costly repairs and keep your system running reliably all season long.
Replace or Clean Your Air Filter
This is one of the simplest maintenance tasks, but also one of the most overlooked. During winter, your furnace runs more often, pulling air through the filter every time it cycles on. A dirty or clogged filter restricts airflow, forcing your system to work harder to heat your home. This extra strain can lead to higher energy bills, uneven heating, and even premature system failure.
What to do:
- Check your filter every 30 days during winter
- Replace disposable filters or clean reusable ones as needed
- If you have pets or allergies, you may need to change filters more often
A clean filter improves efficiency, protects your equipment, and keeps indoor air healthier.
Test Your Thermostat (and Upgrade If Needed)
Your thermostat controls when and how often your heating system runs. If it’s not working properly, your home may feel too cold, too warm, or inconsistent from room to room. Before winter sets in fully, test your thermostat by raising the temperature a few degrees and making sure the system responds normally.
If you’re still using a basic manual thermostat, you may want to consider an upgrade. A programmable or smart thermostat can help reduce energy use by adjusting temperatures when you’re asleep or away. Many homeowners in the St. Louis area see noticeable savings during winter with better temperature control.
Inspect and Clean Vents and Registers
Blocked or dirty vents can disrupt airflow and cause certain rooms to feel colder than others. Furniture, rugs, or curtains, often get moved around during the year and may end up covering vents without you realizing it.
What to Check:
- Make sure all supply and return vents are open and unobstructed
- Vacuum dust and debris from registers
- Check that vents aren’t loose or damaged
Good airflow helps your system heat your home evenly and efficiently. While it’s generally safe to remove the vent cover to clean just inside the duct, avoid sticking any objects deep inside.
Listen for Unusual Noises
Furnaces make some noise during normal operation, but banging, rattling, squealing, or grinding sounds are not normal and shouldn’t be ignored.
These noises can indicate issues such as:
- Loose or worn components
- Belt or motor problems
- Ignition or burner issues
Catching these problems early can prevent a complete system breakdown during the coldest part of winter.
Check Your Furnace Flame and Pilot Light
If you have a gas furnace, take a moment to look at the burner flame. A healthy flame should burn blue. A yellow or flickering flame can indicate dirt buildup or combustion problems, which can affect efficiency and safety. For older systems with a pilot light, make sure it stays lit and burns steadily.
If you notice anything unusual with the flame or smell gas, turn off the system and contact a professional immediately.
Seal Air Leaks Around Your Home
Your HVAC system works harder when warm air escapes your home. In Wichita winters, drafts around winters and doors can significantly impact comfort and energy use.
Common problem areas include:
- Window and door frames
- Attic access points
- Basement or crawl space openings
Using weatherproofing or caulk to seal leaks helps keep warm air inside and reduces how often your furnace has to run.
Clear Snow and Debris from Outdoor Units
If you have a heat pump or other outdoor HVAC components, winter weather can interfere with performance. Snow, ice, and debris can restrict airflow and cause system malfunctions.
There are several best practices to consider to keep your outdoor equipment in good condition. First, keep at least 18 to 24 inches of clearance around outdoor units. Gently remove snow and ice after storms and avoid piling snow near equipment when shoveling. Keeping outdoor components clear helps prevent breakdowns and efficiency issues.
Inspect Ductwork for Leaks or Damage
Leaky or poorly insulated ducts can waste a surprising amount of heat. In some homes, especially older ones common throughout the Wichita area, ductwork may run through unconditioned spaces like basements or attics.
Signs of duct issues include:
- Rooms that never seem warm enough
- Dust buildup around vents
- Higher-than-normal heating bills
Professional duct inspections can identify leaks and insulation problems that reduce system performance.
Schedule a Professional HVAC Tune-Up
Even if everything seems to be running fine, a professional maintenance visit can catch problems you can’t see. During a winter tune-up, an HVAC technician will inspect, clean, and test critical components to ensure safe and efficient operation.
A typical winter maintenance service includes checking heat exchangers and burners, testing safety controls, inspecting electrical components, and measuring system efficiency. Regular maintenance helps extend system lifespan, improve reliability, and reduce the risk of emergency repairs during freezing temperatures.
At Fenix Heating & Cooling, we offer our convenient maintenance plans to keep your HVAC equipment running optimally season to season. Maintenance tune-ups are performed by qualified, trained technicians who always follow manufacturer-recommend procedures. Our maintenance plans includes up to 50 points of inspection and follows bi-annual maintenance protocols.
Don’t Ignore Rising Energy Bills
If your heating bills are climbing faster than usual, your HVAC system may be working harder than it should. Dirty components, airflow problems, or aging equipment can all reduce efficiency.
Pay attention to sudden or unexpected increases in energy usage. It’s often an early warning sign that something isn’t right.
