When the outside temperature climbs past 100°F, an air conditioning system that was merely weak in May becomes useless in July. Heat exposes every small fault at once and that is why our phones ring hardest between June and September.
Low Refrigerant Is a Symptom, Not a Cause
Refrigerant does not get consumed. If your system is low, it is leaking, usually at a fitting, a hose crimp, the condenser, or an aging compressor seal. A recharge without a leak check buys you a few weeks of cold air and another bill later. We pressure-test first, then recharge.
Airflow Problems Look Exactly Like Cooling Problems
A clogged cabin air filter, a failing blower motor, or a stuck blend door will all leave you with warm vents even when the refrigerant circuit is healthy. That is why diagnosis matters more than parts: the fix might be a $30 filter rather than a compressor.
What to Do Before You Call
Note whether the air is warm at idle but cool while driving, whether you hear the compressor click on, and whether the problem started suddenly or faded over weeks. Those three answers narrow the diagnosis before our trailer even reaches your driveway.
Then call or text us. We diagnose on-site anywhere in New Braunfels, Austin, San Antonio, and across Central Texas, 24/7.
