When winter arrives in Huntsville, the last thing you want is a heating system that can’t keep up with the cold. Your HVAC system works overtime during the colder months, and giving it the right care can help you avoid breakdowns, save money on energy bills, and extend its lifespan. A little HVAC maintenance goes a long way when it comes to keeping your home warm and comfortable all winter long.

At Thomas Service Company, we’ve been helping local families stay cozy since 2005, offering trusted HVAC services to prepare systems for the demands of winter. Here are some key tips to help you maintain your HVAC system during the cold season.

1. Replace or Clean Air Filters Regularly

One of the simplest but most important tasks is changing your air filter every 1–3 months. Dirty filters restrict airflow, making your system work harder and less efficiently. A clean filter helps your furnace or heat pump run smoothly and improves indoor air quality.

2. Schedule a Professional Tune-Up

Before temperatures drop too low, it’s a good idea to schedule an HVAC inspection. At Thomas Service Company, our technicians check for worn parts, clean components, and ensure your system is operating safely and efficiently. Preventative maintenance is the best way to stop small issues from turning into costly repairs.

3. Seal Air Leaks Around Your Home

Even the best HVAC system can’t keep up if warm air is escaping through cracks and gaps. Inspect windows, doors, and ductwork for leaks and seal them to prevent heat loss. This will help your system run more efficiently and reduce your energy bills.

4. Keep Vents and Registers Clear

Blocked vents make it harder for your HVAC system to circulate warm air. Make sure furniture, rugs, or curtains aren’t covering your registers so heat can flow evenly throughout your home.

5. Monitor Your Thermostat Settings

Constantly adjusting your thermostat can wear out your system and increase energy costs. Instead, set it to a comfortable, consistent temperature. A programmable or smart thermostat can help you manage heating more efficiently, even when you’re not home.

6. Pay Attention to Warning Signs

Unusual noises, uneven heating, or frequent cycling are red flags that something might be wrong. If you notice these issues, it’s time to call Thomas Service Company for professional help at (256) 908-8588. Prompt attention can prevent a full breakdown in the middle of winter.
