Houston pulls moisture from the Gulf of Mexico. Average relative humidity stays above 65 percent, even in summer. Your air conditioner removes 10 to 20 gallons of water from the air every day. That water drains through a condensate line to the outside. When algae clogs the drain, water backs up into the evaporator housing. If your system is already running with reduced airflow or low refrigerant, that trapped moisture freezes instantly. Ice blocks the coil. Airflow drops to zero. Your compressor runs nonstop but produces no cooling. Emergency AC freeze up repair becomes urgent because the combination of Houston's heat and humidity accelerates the damage. A frozen coil in Phoenix might take two days to cause a compressor failure. In Houston, it happens in hours.
Houston residential HVAC systems face higher condensate loads than almost anywhere in the country. Builders install secondary drain pans and float switches to protect against water damage. City code requires these safeguards because of our flood risk. Titan HVAC Houston knows these local requirements. We inspect secondary drains during every frozen coil repair. We verify float switches are working. We check that the primary condensate line is pitched correctly. We understand that AC evaporator coil icing repair in Houston is not just about fixing the coil. It is about addressing the drainage and humidity challenges unique to the Gulf Coast. National chains do not always understand these local factors. We do.
