Winter is Coming: How to Prepare Your HVAC System for Cold Weather Aug 17, 2025

As the temperatures begin to dip and winter draws near, ensuring your HVAC system is ready to embrace the cold is crucial for maintaining comfort in your home. Brannan’s Heat and Air, your trusted HVAC service company, is committed to helping you keep your system in top shape as the seasons change. Preparing your HVAC system for winter requires some proactive measures to ensure efficiency, reliability, and safety. Here’s a comprehensive guide to get your system winter-ready.

Firstly, scheduling a professional maintenance check should be at the top of your list. During these inspections, a qualified technician from Brannan’s Heat and Air will examine your HVAC system to identify potential issues before they escalate into costly repairs. Trained experts can spot worn-out parts, check electrical connections, and assess the overall functionality of your system. An early inspection not only improves system performance but also extends the lifespan of your equipment.

Next, consider replacing your air filters to maintain optimal indoor air quality. Over time, filters can become clogged with dust, debris, and allergens, restricting airflow and causing your system to work harder than necessary. Replacing filters every 30 to 90 days, depending on usage and household factors, ensures cleaner air and promotes energy efficiency. During winter, when windows are closed and indoor air circulation is limited, having clean filters is even more critical.

Another essential step is to seal your windows and doors adequately. Drafty windows and doors can lead to significant heat loss, forcing your HVAC system to overcompensate and run more frequently. Use weather stripping and caulk to fix any leaks, and consider adding extra insulation in critical areas. Reducing drafts will not only keep your home warmer but also lower heating costs during the chilly months.

Thermostat management plays a pivotal role in your HVAC system's efficiency. Upgrade to a programmable thermostat if you haven’t already. A programmable thermostat allows you to set temperature schedules that align with your daily routine, reducing energy consumption when you’re asleep or away. Adjusting your thermostat a few degrees lower when you’re not home can lead to substantial energy savings without sacrificing comfort.

Moreover, remember to clear any obstructions around your HVAC units. Outdoor units, in particular, may become blocked with debris such as leaves, snow, or ice, which can hinder their performance. Ensure that the area surrounding your external units is clear and routinely check for any debris accumulation. Indoors, keep vents unblocked to allow free airflow, helping your system run more effectively.

Finally, assess your insulation. Proper insulation is vital for keeping warm air inside and cold air out. Attic insulation is particularly important, as heat rises and may escape through poorly insulated roofs. Consider consulting with insulation specialists if you suspect your home’s insulation isn’t adequate for peak winter conditions.

By taking these preventive measures, you ensure that your HVAC system is prepared to meet the demands of winter, keeping your home cozy and conserving energy.
