Experienced HVAC Repair in League City, TX 77573 - Denco Air Conditioning & Heating

In our humid climate, the most frequent cause is restricted airflow, often from a clogged air filter. When airflow is blocked, the coil can't absorb enough heat and drops below freezing, causing condensation to turn to ice. Other common causes include low refrigerant levels or a failing blower fan. Our technicians can quickly diagnose and resolve the issue to prevent further damage to your system.

Given the dust common in our area, we recommend checking your standard 1-inch filter every month and replacing it at least every 60-90 days. If you have pets, allergies, or are in a particularly dusty location, monthly replacement is best. A clean filter is your first defense against poor airflow, which can lead to frozen coils, higher energy bills, and system strain.

Absolutely. Our preventative maintenance service is designed specifically for League City homes. We thoroughly clean the system, check refrigerant levels, inspect electrical components, and ensure the blower motor is functioning correctly. This proactive check-up catches small issues before they lead to a frozen coil or complete breakdown, saving you money and ensuring comfort, especially before our hot summers and occasional chilly winters.
