Cosby's Heating & Cooling-Appliance Services | Best HVAC Repair in Dothan, AL

Common signs include your AC running constantly but not cooling effectively, ice forming on the refrigerant lines or outdoor unit, a noticeable hissing or bubbling sound from the system, and a sudden spike in your energy bills. If you notice any of these, it's time to call Cosby's for a professional leak detection and repair service to prevent further damage and restore efficiency.

In Dothan's climate, with higher pollen counts and seasonal changes, we recommend checking your air filter every month and replacing standard 1-inch filters every 30-60 days. Homes with pets or allergy sufferers may need more frequent changes. A clogged filter restricts airflow, forcing your system to work harder. Our team can assess your specific needs during a maintenance visit.

Absolutely. A clean air filter is the first line of defense for your HVAC system. Restricted airflow from a clogged filter causes your AC to strain, reducing cooling capacity, increasing wear and tear on components, and raising energy costs. Regular filter changes, part of our preventative maintenance service, are a simple, cost-effective way to maintain peak efficiency and prolong the life of your system.
