How AC Repair Works in San Antonio
What to expect from a licensed San Antonio HVAC contractor from first call to completion.
- 1
Diagnostic Assessment
Technician inspects the full system — thermostat, electrical connections, refrigerant levels, and mechanical components — to identify the root cause of failure.
- 2
Component Testing
Individual components (capacitor, contactor, blower motor, compressor) are tested under load to confirm what needs replacement vs what is within spec.
- 3
Repair & Recharge
Faulty components are replaced with manufacturer-spec parts. If low refrigerant is found, the leak is located and sealed before recharging to the correct level.
- 4
System Performance Test
System is run through a full cooling cycle. Supply and return air temperatures are measured to confirm the system is achieving the correct temperature differential (typically 16-22°F).
- 5
Documentation & Recommendations
A written service report is provided. If other components are approaching end of life, the technician documents findings and provides a timeline recommendation.
Frequently Asked Questions About AC Repair in San Antonio, TX
What are the most common reasons an AC stops cooling?
The most common causes are a faulty capacitor (the most frequent failure point), low refrigerant from a leak, a dirty condenser coil that can't reject heat, a frozen evaporator coil from airflow restriction, a failed contactor, or a tripped breaker. A licensed HVAC technician can diagnose the root cause within 30–60 minutes and provide a written repair estimate.
How long does an AC repair take?
Most common AC repairs — capacitor replacement, refrigerant recharge, contactor swap — are completed in 1–2 hours on the same visit. More involved repairs like coil cleaning, blower motor replacement, or refrigerant leak location and repair may require 2–4 hours or a follow-up visit if parts need to be ordered. Emergency same-day service is available from most licensed HVAC contractors.
Does homeowner's insurance cover AC repair or replacement?
Standard homeowner's insurance typically does not cover HVAC repairs due to normal wear and mechanical failure — those are maintenance items. However, AC damage caused by a covered peril (lightning strike, electrical surge, fire, storm) is often covered. Separate HVAC breakdown coverage or a home warranty plan can cover mechanical failures. Check your policy or home warranty terms before paying out of pocket.
Can I recharge my AC refrigerant myself?
No — refrigerant handling requires EPA Section 608 certification and specialized recovery equipment. It is illegal to release refrigerants (R-410A, R-22, R-32) into the atmosphere. Additionally, adding refrigerant without fixing the underlying leak is a temporary fix that will fail again quickly. A licensed HVAC technician will locate the leak, repair it, and recharge the system to manufacturer specifications.
Is it worth repairing an AC unit that is 10 or more years old?
The industry rule of thumb is the "Rule of 5,000": multiply the repair cost by the system's age. If the result exceeds $5,000 (e.g., a $400 repair on a 15-year-old unit = $6,000, over the threshold), replacement is likely the better long-term value. At 10–12 years, a licensed technician can assess remaining compressor life and give you a repair vs. replace recommendation in writing.
