Dirty or clogged filters restrict airflow, forcing your system to work harder and reducing efficiency. Fresh filters not only improve air quality but also lower strain on the furnace and air conditioner.<\/p>\r\n<p><strong>Tip:<\/strong> Check filters monthly during heavy use and replace them at least every 1\u20133 months. In St. Louis, where fall brings allergens like ragweed, clean filters can also help <a href=\"https:\/\/www.galmicheandsons.com\/hvac-blog\/tips-to-improve-indoor-air-quality-in-fall\/\">improve indoor air quality<\/a>.<\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"Clear_Debris_Around_the_Outdoor_Unit\"><\/span>Clear Debris Around the Outdoor Unit<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>Leaves, grass, and other yard debris can collect around your outdoor AC condenser or heat pump. This buildup restricts airflow and can affect efficiency. Before winter arrives, take a few minutes to:<\/p>\r\n<ul>\r\n<li>Trim back shrubs and plants at least two feet from the unit<\/li>\r\n<li>Remove leaves and twigs from the top and sides<\/li>\r\n<li>Gently rinse off dirt with a garden hose (avoid using high pressure)<\/li>\r\n<\/ul>\r\n<p>This small step helps ensure your HVAC system can operate without obstruction.<\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"Check_Thermostat_Batteries\"><\/span>Check Thermostat Batteries<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>When temperatures swing between warm days and cool nights, you&#8217;ll be adjusting your thermostat often. A simple but often overlooked DIY fall HVAC maintenance task is checking and replacing thermostat batteries. Weak batteries can cause your thermostat to malfunction, leaving you without heat when you need it most.<\/p>\r\n<p><strong>Tip:<\/strong> Consider upgrading to a programmable or smart thermostat to improve energy efficiency and comfort throughout the heating season.<\/p>\r\n<h3><span class=\"ez-toc-section\" id=\"Seal_Air_Leaks_in_Your_Home\"><\/span>Seal Air Leaks in Your Home<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<p>Drafts and leaks can waste energy and reduce comfort.
