What Your HVAC Contractor Wants You To Know Before Winter

Winter in Texas may not be as harsh as in northern states, but that doesn’t mean your heating system isn’t vital. Even the mildest winter nights can be uncomfortable—or even unsafe—if your furnace or heating system isn’t functioning properly. At Texas Air Authorities, we’ve worked with countless homeowners across the Dallas–Fort Worth Metroplex, and we want you to be fully prepared for the colder months. Here’s what your HVAC contractor wants you to know before winter arrives.

1. Schedule a Professional Maintenance Check

One of the most important steps before winter is scheduling a professional inspection of your heating system. This is not just about turning the system on; it’s about checking for potential issues that could leave you in the cold. A comprehensive winter tune-up includes:

1. Checking the furnace or heat pump for proper operation 
2. Inspecting electrical components and wiring 
3. Testing safety features and controls 
4. Cleaning or replacing air filters 
5. Examining ductwork for leaks or blockages 

Regular maintenance ensures your system operates efficiently, reduces the risk of breakdowns, and prolongs its lifespan. At Texas Air Authorities, our NATE-certified technicians provide same-day service and free estimates to make maintenance convenient and hassle-free.

2. Change or Clean Your Air Filters

It’s a simple step, but many homeowners overlook it. Clean filters are crucial for proper airflow, efficiency, and indoor air quality. Dirty filters force your system to work harder, increasing energy costs and potentially causing wear and tear. Before winter, replace disposable filters or clean reusable ones to ensure your furnace can heat your home effectively.

3. Test Your Thermostat

Your thermostat is your primary control over your home’s comfort. Before the cold sets in, make sure it’s functioning correctly. Check that the batteries are fresh, settings are correct, and if you have a programmable thermostat, verify that it follows your preferred schedule. A malfunctioning thermostat can make it seem like your furnace isn’t working—even if it is. Texas Air Authorities can recalibrate or replace your thermostat to ensure accurate, reliable control of your home’s temperature.

4. Inspect Your Ductwork

Leaky or poorly insulated ducts can waste up to 30% of your heating energy. Cold air escaping into unheated spaces or hot air not reaching your living areas reduces comfort and increases energy bills. Before winter, have your ductwork inspected for leaks, loose connections, or insulation gaps. Properly sealed ducts help your system perform efficiently, keeping every room warm without overworking your furnace.

5. Watch for Carbon Monoxide Hazards

Furnaces that burn fuel, such as natural gas or propane, need proper ventilation to operate safely. Carbon monoxide (CO) is odorless and deadly, making CO detectors essential in every home with a combustion furnace. During a winter inspection, your HVAC contractor will check for leaks, proper venting, and safe operation to protect your family. At Texas Air Authorities, safety is always a top priority.

6. Know the Signs of a Furnace Problem

Even with regular maintenance, furnaces can develop issues. Be alert for these warning signs:

1. Strange noises, such as banging, clanking, or squealing 
2. Uneven heating or cold spots in your home 
3. Frequent cycling on and off 
4. Rising energy bills without increased usage 

If you notice any of these signs, don’t wait—call your HVAC contractor immediately. Early intervention prevents bigger problems and avoids being without heat on the coldest nights.

7. Consider an Upgrade if Your System Is Old

Furnaces and heat pumps have a typical lifespan of 15–20 years. If your system is nearing or exceeding this age, winter is a perfect time to consider an upgrade. Modern units are more energy-efficient, provide more consistent heating, and include features like programmable thermostats and improved filtration. At Texas Air Authorities, we offer expert recommendations and installations for all makes and models, including Lennox, Trane, and Goodman, helping you choose the right system for your home and budget.

8. Plan Ahead for Emergency Service

Winter emergencies can happen at any time. Having a go-to HVAC contractor ensures you can get help quickly if your system fails. Our team at Texas Air Authorities provides same-day appointments, reliable repairs, and clear explanations of your options. By planning ahead, you reduce stress and ensure uninterrupted comfort for your family.

9. Take Advantage of Energy Efficiency Tips

Your HVAC contractor can provide tips to reduce energy consumption while keeping your home warm. Simple steps include:

1. Sealing windows and doors to prevent drafts 
2. Using programmable thermostats to reduce unnecessary heating 
3. Keeping vents and registers clear of obstructions 

These small adjustments can add up to noticeable savings on your winter energy bills while keeping your home comfortable.

Conclusion

Preparing your heating system before winter isn’t just about comfort—it’s about safety, efficiency, and protecting your investment. From professional maintenance and clean filters to duct inspections, thermostat checks, and CO safety, taking the time now can prevent headaches later.
