Furnace Prep Checklist for Cold Weather in North Texas

Though it may not be as often as other homes in the Midwest, whenever you use your furnace in North Texas, it’s essential to make sure it can heat your home efficiently and thoroughly. That kind of assurance requires preparing the furnace for consistent use throughout the colder months. 


To that end, the following furnace prep checklist in North Texas will help ensure you get the best use of your heating equipment throughout the winter season:


Schedule Professional Heating Maintenance

A professional inspection and tune-up go hand-in-hand as an essential part of preparing your furnace for winter use. Your HVAC technician will clean the burners, check the heat exchanger for damage, and perform other fine-tuning services. They will also look for problems that could affect your heating performance, giving you time to schedule repairs before a cold snap takes hold.


Stock Up on Air Filters for Your Furnace

During a tune-up, your HVAC technician will replace your furnace’s old air filter. But even outside of regular maintenance visits, you should plan to replace the filter yourself every 30 days. A dirty air filter inhibits airflow, leading to increased energy waste, a faster rate of wear and tear, and diminished indoor air quality. 


Clean and Check Your Ductwork

A truly comprehensive furnace prep checklist in North Texas actually goes beyond the furnace and involves other components in your heating system. Dirty or corroded ducts, for instance, can affect the flow of heated air into your living spaces, so make sure to wipe down your registers and vents. You can also ask your HVAC company to provide duct cleaning every three years to remove debris and check for damage.


Test Your Thermostat

Make sure to set your thermostat from “Cool” to “Heat,” then adjust the temperature by a few degrees to initiate a heating cycle. If your furnace doesn’t start, your thermostat might need recalibration; ask your HVAC technician to diagnose and fix the problem.


Replace the Batteries in Your Alarms

As you rely on these detectors to alert you to hazardous furnace malfunctions, make sure to install new batteries in your carbon monoxide and smoke detectors (as well as your thermostat), then test each unit to make sure they’re operating correctly.
