What Affects AC Repair Cost in Houston?
System Age
Older systems require harder-to-source parts and may have multiple failing components. A 15+ year old system may need $1,200 in repairs that only delay inevitable replacement.
Brand and Model
Premium brands like Carrier or Trane have higher parts costs. Budget brands like Goodman or Rheem have lower parts costs. We service all brands at honest prices.
Refrigerant Type
R-22 (old systems) is expensive and being phased out — $50-80/lb vs R-410A at $10-20/lb. If your system uses R-22, a leak repair may cost significantly more.
Labor Time
Simple capacitor swaps take 30 minutes. Coil replacements take 4-6 hours. More complex repairs mean higher labor costs — but we always give you the price upfront.
Repair vs. Replace — When to Choose Each
Use the 50% Rule: if the repair cost exceeds 50% of the replacement cost AND your system is over 10 years old, replacement usually offers better long-term value. AOT Mechanical gives you honest guidance — we'll tell you which option makes more financial sense, not which is more profitable for us.
- ✅ Repair: System under 10 years old, repair under $1,000, no history of multiple failures
- ⚠️ Consider replacing: System over 12-15 years, compressor failure, R-22 refrigerant, repeated repairs
