Every rooftop unit reaches a point where the question stops being “how do we fix it” and becomes “should we fix it at all.” TechBridge Pacific HVAC corp helps McKinney businesses make that call with real numbers, not a sales pitch toward the more expensive option. We service the McKinney commercial corridor — from US-75 to Craig Ranch — and repair-vs-replace is one of the most common conversations we have with property owners here.
When Repair Still Makes Sense
- Unit is under 10 years old and this is its first major failure.
- The failed part (capacitor, contactor, motor) is a small fraction of replacement cost.
- Refrigerant charge is intact and the system was running efficiently before the fault.
When Replacement Is the Better Number
- Age past 15 years — efficiency has already dropped well below a new unit’s rating.
- Running on R-22 — a refrigerant being phased out; a leak means an increasingly expensive top-off, not a routine recharge.
- Second or third major repair in under two years — the “rule of thumb” is if repair cost exceeds roughly half of replacement cost on an aging unit, replace.
- Unit undersized or oversized for current use — common after a tenant change or renovation in McKinney’s growing retail spaces.
We’ll give you the honest number both ways — repair cost and replacement cost, with the reasoning behind each — before you decide anything. See our checklist for choosing a commercial HVAC contractor in McKinney if you’re evaluating who to trust with either option.

Recent McKinney Work
Recent calls in McKinney have included a kitchen exhaust-fan VFD fault (fan wouldn’t start, part sourced and installed within days) near W. University Dr, and a rooftop-unit follow-up visit off Woodbridge Dr confirmed fixed on the callback. That is the kind of diagnostic-first, verify-the-fix approach that shapes every repair-vs-replace call we make here.
