A homeowner in League City noticed that their air conditioning system was not cooling the house effectively, leaving some rooms warmer than others.
Brandon discovered that the issue was due to a clogged air filter, which was restricting airflow and causing the system to underperform.
Brandon replaced the clogged air filter with a new one, ensuring that the system could breathe properly. He also checked the overall system for any additional blockages and confirmed that the refrigerant levels were adequate.
After the service, the AC system was able to cool the home evenly, restoring comfort to all rooms.
A clogged air filter can significantly reduce your AC's efficiency. Change your air filter every 1-3 months, especially during peak cooling season, to ensure optimal airflow and performance.
