When to Call an HVAC Technician in San Marcos — 4 Warning Signs
Don't ignore these common indicators — early action prevents costly damage and saves money.
Uneven Temperatures Between Rooms
If some rooms are too hot while others are freezing, your ductwork may have leaks (which waste 20-30% of conditioned air per ENERGY STAR) or your system may be improperly sized for your home.
Frequent On/Off Cycling (Short Cycling)
Short cycling puts excessive wear on compressors and motors, reducing system lifespan by up to 40%. Common causes include thermostat issues, refrigerant leaks, or an oversized unit.
Strange Odors When System Runs
Musty smells suggest mold in ductwork (affects 1 in 5 homes per EPA), burning odors indicate electrical issues, and rotten egg odors may signal a gas leak requiring immediate evacuation.
System is Over 15 Years Old
HVAC systems lose 5% efficiency per year after age 10. A 15-year-old system may be operating at 50-60% of its original efficiency, making replacement more cost-effective than repair.

What San Marcos Homeowners Ask About Thermostat Upgrade
Should I repair or replace my HVAC system in San Marcos?
The '5,000 Rule' helps: multiply the system's age by the repair cost. If the result exceeds $5,000, replacement is usually more cost-effective. Other replacement indicators include: the system uses R-22 refrigerant (phased out, expensive), repair costs exceed 50% of a new system, or energy bills have increased 15%+ despite maintenance. ProHVAC West Lake Hills AC Repair & Heating Services provides honest assessments for San Marcos homeowners — we won't push replacement when a $200 repair solves the problem.
