Cobb Heating & Cooling | Certified HVAC Services in Corydon, IN

For most homes in our area, we recommend checking your air filter every month and changing it at least every 90 days. During peak summer or winter use, or if you have pets or allergies, changing it every 30-60 days is better. A clean filter protects your system from dust and debris, improving efficiency and preventing costly repairs.

The condenser coil releases heat from your home. In Corydon's environment, it can get clogged with grass clippings, pollen, and dirt. A dirty coil makes your AC work much harder, leading to higher energy bills and potential overheating or failure. Regular professional cleaning as part of a maintenance visit ensures optimal cooling and can prevent a mid-summer breakdown.

Common signs include unusual noises, weak airflow, uneven heating or cooling, a sudden increase in your energy bill, or your system constantly cycling on and off. If you notice any of these, it's time to call us. Regular professional maintenance can catch small issues like a clogged filter or dirty coil before they turn into major, expensive repairs.
