HVAC Repair Austin TX | Call Mike's Heat and Ac

Short cycling is often caused by an oversized unit, a dirty air filter, low refrigerant, or a faulty thermostat. It strains your system and hikes up energy bills. Our technicians will perform a comprehensive diagnostic to pinpoint the exact cause—whether it's a simple filter change, recharging refrigerant, or calibrating your thermostat—and provide a lasting repair to restore efficient operation.

A frozen coil is a sign of a serious issue, like low airflow or refrigerant problems, and running the system can cause further damage. Yes, it requires prompt attention. We'll safely thaw the coil and then diagnose the root cause, which is often a dirty filter, blocked vents, a failing blower motor, or a refrigerant leak. Our repair service addresses the underlying problem to prevent a costly repeat freeze-up.

We strongly recommend bi-annual maintenance, ideally in spring and fall. Our preventative maintenance visit includes cleaning coils, checking refrigerant levels, calibrating thermostats, inspecting electrical components, and ensuring proper airflow. This proactive service is the best way to catch small problems early, improve efficiency, extend your system's life, and prevent disruptive breakdowns during our hottest and coldest months.
