While Texas winters are generally mild, those in West Texas can vary drastically. The region’s unique climate often brings cold, damp conditions that can impact your home’s comfort and efficiency. 


As the colder months approach, it's important that your heating system is ready to handle the additional load. Taking a few proactive steps now can help you stay comfortable, improve efficiency and prevent costly repairs later. Let’s look at seven ways West Texas homeowners can prepare their heating systems for winter.


1. Check You Carbon Monoxide Detector


If you have a carbon monoxide detector, it’s essential to check it before winter arrives. As you rely on your furnace more during the colder months, the risk of a carbon monoxide leak increases. Ensuring your detector is working properly helps protect your household from this toxic gas and provides peace of mind while your system is in use. 


2. Seal Gaps and Drafts


Make sure your windows, doors, and attic spaces are free of gaps and leaks. While they may seem small, air leaks can make your home colder and force your heating system to work harder. Weatherstripping or caulking can be used to seal leaks, ensuring your heating system isn’t compensating for heat loss.


3. Check Your Vents and Registers


Keeping your vents and registers open ensures warm air is being delivered throughout your home. When vents are blocked by furniture, rugs or other objects, your heating system has to work harder to distribute warm air, which can increase energy costs and put unnecessary strain on the system. Blocked vents can also lead to uneven heating, leaving some rooms too cold while others become stuffy or overheated. 


4. Cover Your Outdoor Unit


Since your air conditioning unit won’t be in use during the winter, it’s a good idea to cover it for protection. A durable cover shields the unit from ice, snow and debris, which can cause damage to your unit over time. Taking this step ensures your AC unit is in top condition when spring arrives, saving you time and money on potential repairs.


5. Replace Your Air Filters


Replacing your air filters during the winter can improve efficiency and extend the lifespan of your HVAC system. Dirty or clogged filters restrict airflow, which forces your furnace or heat pump to work harder to heat your home, reducing efficiency and adding wear to your HVAC system. 


Clean filters also improve indoor air quality by trapping dust, allergens and other particles. This is especially helpful for family members with asthma or allergies, since cooler months often mean spending more time indoors.


6. Upgrade Your Insulation


Add insulation to your attic and walls to retain more heat. Insulated ductwork can also prevent heat loss in your HVAC system. A professional HVAC technician should do this. It’s not a diy job and requires expertise and proper equipment. 


Having the right amount of insulation can significantly improve comfort. Insulation prevents colder air from entering your home, helping your home stay warmer for longer. This not only improves comfort but also reduces the workload on your heating system.


A more efficient heater can lower energy bills and prevent uneven temperatures throughout your home. Additionally, well-insulated walls and attics can help protect against moisture buildup, reducing the risk of mold infestation.


7. Get your Heating System Serviced


If you haven’t had your furnace or sump pump serviced in a while, it’s important to schedule an inspection before winter arrives. Regular maintenance ensures that your furnace is running efficiently and safely.


Similarly, a serviced sump pump can prevent flooding and water damage during heavy rains, snowfall or ice melt. Plus, having a licensed HVAC technician perform thorough inspections can prevent small repairs from developing into costly repairs.
