Licensed, Insured, and Experienced Houston AC Technicians
Every 75 Degree AC technician holds a TACLA license (TACLA72152E) and EPA 608 certification, plus general liability insurance that protects your home during every visit. Our team has spent years repairing leaks across Houston’s older bungalows and newer high rise units alike, so no system type catches us off guard.
If you’re searching for an HVAC contractor for a leaking AC near Houston, our techs arrive trained on the exact refrigerant types and drain configurations local homes use. We stand behind every repair with a written workmanship guarantee, not just a verbal promise.
Why Houston's Climate and Housing Stock Make AC Leaks More Common
Houston’s cooling season runs from March through October, and humidity levels above 70 percent keep your AC removing moisture nonstop, which strains condensate lines and coils. That constant workload is a major reason AC leak repair in Houston stays in demand year after year.
Houston also has no traditional zoning, so pre-war bungalows, mid-century ranch homes, and new high rise condos sit in the same neighborhoods, each with different drain layouts and refrigerant lines. Our technicians see this mix daily, which is why we diagnose leaks based on your home’s actual age and setup, not a generic checklist.
Signs of an AC Leak in Houston Homes (Water vs. Refrigerant)
Most AC leaks fall into two categories, refrigerant leaks and condensate water leaks, and each one shows different warning signs.
- Water pooling near the indoor air handler or dripping from the ceiling
- A clogged or cracked condensate drain line or drain pan
- Warm air blowing from vents despite the system running
- Frost or ice forming on the evaporator coil
- A hissing sound near the outdoor unit or compressor
- Rising energy bills without a change in usage
Knowing which type you’re dealing with is the first step to getting the right AC leak repair in Houston, since refrigerant and water leaks need different tools and techniques to fix.
How We Diagnose the Exact Source of the Leak
Guessing at a leak location leads to repeat repairs, so our technicians run a structured diagnostic before touching any component.
Electronic Leak Detection
We use an electronic refrigerant sniffer to scan coils, fittings, and line sets, pinpointing the exact leak point without guesswork.
UV Dye Testing
For slow or hard to trace leaks, we inject a UV dye into the refrigerant line and use a UV lamp to spot the exact escape point.
Condensate Drain Line Inspection
We check the drain line and drain pan for clogs, cracks, or disconnections, since water leaks often trace back to a blocked drain path.
System Pressure Testing
We pressure test the sealed system to confirm the leak is fixed and the system holds refrigerant at the correct level before we close the job.
Our AC Leak Repair Process, Step by Step
Once we confirm the leak location, our AC leak repair in Houston follows a clear repair sequence, not a one size fits all patch job.
Coil Sealing or Component Replacement
If the leak is in the evaporator or condenser coil, we seal small pinholes or replace the coil when the damage is too extensive to repair safely.
Drain Line Clearing
For water leaks, we clear the condensate drain line of algae, dirt, and debris, then check the drain pan for cracks that need replacing.
Refrigerant Recharge
Once the leak is sealed, we recharge the system with the correct refrigerant type and amount, based on your unit's manufacturer specs.
Final Pressure Test and Airflow Check
We pressure test the sealed system again and check airflow and cooling output, confirming the repair holds before we consider the job done.
Preventing Future AC Leaks with Routine Maintenance
Most leaks build slowly through clogged drain lines, worn seals, or coil corrosion, and a seasonal AC tune up catches these issues before they cause water damage or a full breakdown. Our maintenance visits include a drain line flush, coil inspection, and refrigerant level check, so small problems get fixed while they’re still cheap to fix.
Homeowners who schedule maintenance twice a year, once before summer and once before winter, see fewer emergency repair calls and lower cooling costs over time. If you’ve had a leak repaired recently, staying on a maintenance schedule is the best way to protect that AC repair and extend your system’s lifespan.
What Affects the Cost of AC Leak Repair in Houston
Repair cost depends mainly on leak location, refrigerant type, and how much labor the fix requires, with accessible coil leaks costing less than hidden line set leaks behind walls or ceilings. Older systems running R-22 refrigerant typically cost more to recharge than newer R-410A or R-32 systems, since R-22 is being phased out and harder to source.
System age also plays a role, since older units often need extra labor to access worn components or match discontinued parts. We give you a flat rate quote after diagnosis, before any repair work starts, so you know the full cost upfront with no surprise charges later.

Frequently Asked Questions
Is an AC refrigerant leak dangerous to my health?
Refrigerant exposure can cause dizziness or headaches in large amounts, but small leaks in a well ventilated home are low risk. Still, always have a licensed technician handle repairs, since EPA regulations require certified handling.
Can I fix an AC leak myself?
Clearing a clogged drain line is sometimes a DIY task, but refrigerant leaks require EPA 608 certified handling and specialized tools to diagnose and seal safely.
How long does AC leak repair take?
Most leak repairs take 1 to 3 hours, depending on whether the leak is easily accessible or hidden behind walls, ceilings, or ductwork.
Will my AC leak come back after repair?
A properly sealed and pressure tested repair should hold long term, though older systems with multiple worn components may develop new leaks over time.
Does homeowners insurance cover AC leak repair?
Coverage varies by policy and cause; sudden accidental damage is sometimes covered, but gradual wear and lack of maintenance usually are not. Check with your provider directly.

Frequently Asked Questions
Is It Safe to Keep Running My AC If I Suspect a Refrigerant Leak?
Running an AC with a refrigerant leak puts increasing strain on the compressor with every cooling cycle. The system works harder to compensate for the lost charge, which generates more heat and wear on internal components. Continuing to run it risks turning a repairable leak into a full compressor failure. Shut the system off and schedule a diagnostic as soon as possible.
What Should I Do If My AC Is Leaking Water Inside the House?
Turn the system off to prevent further overflow and water damage. Check if the drain pan under the indoor unit is full. Do not run the AC until the drain line is cleared. A blocked condensate drain is one of the fastest and most common AC leak repairs, and most are completed on the same visit.
Can a Refrigerant Leak in a Home AC System Be Fixed Permanently?
Yes, in most cases. Line set and fitting leaks are sealed and pressure-tested to confirm they hold. Evaporator coil leaks caused by corrosion may require section repair or full coil replacement depending on severity. A properly sealed and pressure-tested repair will hold long term.
How Can I Tell If My AC Is Leaking Refrigerant or Just Losing Cooling?
A refrigerant leak usually shows specific signs: ice forming on the line set or indoor coil, a hissing or bubbling sound near the unit, and the system running longer without reaching the set temperature. If you have recharged the system before and it lost cooling again within months, a leak is almost certainly the cause.
