How can I improve my AC’s performance during extreme summer heat?

• To keep your air conditioner running efficiently in Charleston AFB’s hot summers, make sure to replace air filters regularly, keep vents unobstructed, and schedule professional maintenance at least once a year. If your AC still struggles, upgrading to a high-efficiency system may be the best solution.

Why does my furnace emit a burning smell when I turn it on?

• A slight burning smell when you first turn on your furnace is normal, as dust burns off the heating elements. However, if the smell lingers or smells like plastic or smoke, turn off your system and contact a professional immediately to check for electrical issues or overheating components.

How often should I have my heat pump serviced?

• Heat pumps should be serviced twice a year—once before summer and once before winter. Since they provide both heating and cooling, regular maintenance ensures they operate efficiently in all seasons and helps prevent unexpected breakdowns.

What are the benefits of duct sealing for my HVAC system?

• Sealing leaky ducts improves airflow, prevents energy loss, and helps maintain consistent temperatures throughout your home. It also reduces strain on your HVAC system, which can lower energy bills and extend the lifespan of your equipment.
