Hello all, we share home energy efficiency guides and we often see that air leakage, insulation gaps, and incorrect thermostat settings can raise monthly costs. 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.
