Repair or Replace?
The Quantum Rule
- System is under 10 years old
- Failure is an isolated component (capacitor, fan motor)
- Repair cost is less than 30% of a full replacement
- System is 12+ years old (or uses R-22)
- Facing a catastrophic failure (compressor/coil leak)
- Current system was never sized correctly to begin with
What Counts as "Apples-to-Apples"?
Our estimate-beat guarantee is real, not gimmicky. To qualify, the competitor's comparison must match on:
- Comparable equipment tier (Exact SEER2 rating)
- Comparable manufacturer warranty coverage
- Comparable installation scope (Line-sets/Electrical work)
- Fully Licensed & Insured contractor status
- Current written estimate (issued within Fayette County)
*Note: If a cheaper quote leaves out vital code work, copper materials, or proper startup testing, it is not the same job. We will review their estimate and show you the difference clearly.
