How to Prepare Your HVAC System for Extreme Weather Conditions Jan 07, 2026

As we brace for extreme weather conditions, ensuring your HVAC system is prepared can make a significant difference in maintaining comfort and reducing stress. At Brantley's Heating and Cooling, we understand that a well-functioning HVAC system is crucial during the most intense seasonal shifts. Whether you're gearing up for a scorching summer or an icy winter, here are some practical steps to prepare your HVAC system for whatever Mother Nature throws your way.

First, consider scheduling a professional inspection with Brantley’s Heating and Cooling. Regular maintenance every six months is critical, especially before the onset of extreme weather. Our experienced technicians can identify and fix minor issues before they escalate into costly repairs. Maintenance inspections typically involve checking the thermostat settings, tightening electrical connections, lubricating moving parts, and checking the refrigerant level and air filter.

Next, air filter maintenance is a simple yet essential task that you can handle on your own. A clogged filter forces your HVAC system to work harder, increasing energy consumption and potentially leading to breakdowns. Check your air filters monthly and replace them every 1-3 months depending on usage and the type of filter. This small step not only improves air quality but also enhances the efficiency of your HVAC system.

As temperatures fluctuate, ensuring proper insulation around your home can significantly impact the performance of your HVAC system. Check for gaps or leaks in windows and doors that could let heat escape in winter or enter in summer. By sealing any leaks, you help your HVAC system maintain the desired indoor temperature with less energy. Consider adding weather stripping or caulking to enhance your home’s seal against the elements.

Investing in a programmable thermostat is another effective measure to ensure your HVAC system operates efficiently during extreme weather conditions. With a smart thermostat, you can set specific temperatures for different times of the day, optimizing energy use when you're away from home. This tool allows for greater control over your system and can lead to substantial energy savings.

For those anticipating harsh winters, it’s wise to clear the area around outdoor HVAC units to prevent ice and snow accumulation, which can obstruct airflow. In contrast, during the summer months, ensure that shrubs and debris are cleared away to allow the unit to vent heat away effectively. Keeping a two-foot clearance around the unit will help maintain optimal performance.

Testing and cleaning your HVAC system’s drainage system is also crucial. Clogs in the drainage line can cause water damage and affect indoor humidity levels. Regular monitoring and cleaning can prevent serious issues and ensure that your HVAC system remains in peak condition year-round.

Finally, consider the age and efficiency of your current HVAC system. If your system is older than 10-15 years, it may be time to discuss a replacement with Brantley's Heating and Cooling. Newer systems offer higher efficiency, reducing your utility bills and ensuring reliable performance during extreme weather.

Preparing your HVAC system for extreme weather may seem daunting, but with these actionable steps, you can rest assured that your home will remain comfortable regardless of outdoor conditions.
