home energy efficiency - Thelma 2026/02/02(Mon) 18:21 No.2503489 home energy efficiency 投稿者：【Thelma】 投稿日：2026/02/02(Mon) 18:21 No.2503489 <Home> Hi everyone, we share home energy efficiency guides and we commonly find that drafts, duct leaks, and poor airflow can create hot and cold spots. If your AC is not cooling evenly, your furnace is not heating evenly, or you have weak airflow from vents, consider a basic checklist: check filters, confirm supply vs return airflow, and look for air sealing opportunities. Happy to answer questions about blower door tests, air sealing tips, HVAC performance testing, smart thermostat savings, or insulation R values.
