10 Seasonal Tips to Prepare Your HVAC System for Extreme Weather Aug 21, 2025

As the seasons shift, so do the demands on your HVAC system. Temperatures can swing to extremes, pushing your heating and cooling equipment to its limits. Ensuring your HVAC system is prepared for these environmental challenges is crucial to maintaining comfort in your home. At Brannan’s Heat and Air, we take pride in helping our customers optimize their HVAC systems. Here, we provide crucial tips to prepare your system for extreme weather, enhancing efficiency and longevity.

Your first step should be a thorough inspection and servicing of your HVAC system. A professional check-up can identify any underlying issues that could become problematic under extreme weather conditions. At Brannan’s Heat and Air, our technicians are skilled in spotting potential problems and providing timely solutions, thus preventing costly breakdowns.

Next, change air filters regularly. This is an easy yet often overlooked maintenance task. Filters should be replaced every one to three months, especially before the change of a season. Clean filters improve air quality and ensure your system runs more efficiently, hence reducing energy costs.

Check your thermostat settings to ensure they are optimized for your comfort and efficiency. Consider upgrading to a programmable or smart thermostat. These devices allow you to regulate your home’s temperature even when you are away, adapting to daily patterns and delivering potential savings on your energy bill.

Insulation plays a critical role in keeping your home comfortable throughout changing weather conditions. Check for any leaks or insufficient insulation, particularly around windows and doors. Proper insulation ensures that your HVAC system does not have to work harder than necessary to maintain desired temperatures, which can lead to significant energy savings.

Cleaning the outdoor unit is another essential tip. Over time, debris and dirt can accumulate around your HVAC’s external components, possibly hindering their efficiency. Ensuring that your outdoor unit is free from obstructions will aid in optimal air circulation and extend the unit's lifespan.

Seal any leaks in the ductwork. Leaky ducts can result in loss of heated or cooled air, which forces your system to operate longer, wasting energy. Sealing duct leaks can improve airflow and increase your system’s efficiency by up to 20 percent.

It’s also important to schedule a professional energy audit. Through this, you can assess your home’s energy consumption and measure your HVAC system’s efficiency. The audit will help identify areas that can be improved, which is invaluable in preparing for weather extremes.

Clear space around vents and registers. Maintaining unobstructed airflow throughout your home will ensure even temperature distribution and prevent overworking your HVAC system during peak seasons.

Ensure your system is free from noise disturbances. Strange noises often indicate potential mechanical issues. If your system starts making odd sounds, it's a sign that professional maintenance from experts like Brannan’s Heat and Air is needed.

Finally, make use of window shades and blinds. During summer, keeping curtains closed can keep your home cooler, while opening them during winter days can leverage natural heating from the sun. This simple practice can further reduce the workload on your HVAC system.

Preparing your HVAC system for extreme weather doesn’t have to be a daunting task. With regular maintenance and a few proactive measures, your system can run smoothly all year long, ensuring the comfort and safety of your home. At Brannan’s Heat and Air, we’re here to assist you with all your HVAC needs, ensuring that you’re well-equipped to handle whatever the weather throws your way.
