Guarantees you can verify — including a signed 26-point install
Owner-run Six Star documents the work. Flat-rate diagnostics, commissioning that matches Pittsburgh homes, and a satisfaction standard that means we finish the scope we sold.
What we stand behind
Flat-rate diagnostics
You approve a defined diagnostic price before the meter runs. If repair expands, you approve the next scope — not an open-ended hourly surprise.
Signed 26-point install checklist
Qualifying installs are commissioned against a written checklist so airflow, charge, safety, and controls are not “tribal knowledge” that leaves with the truck.
100% satisfaction on qualifying work
If we missed the agreed scope, we make it right. Terms are on your paperwork — ask before you sign if anything is unclear.

- Refrigerant charge set by measurement — not guesswork
- Electrical, disconnects, and safety devices confirmed
- Condensate management that won’t soak a Carnegie basement
- Thermostat / control staging set for the equipment you bought
- Commissioning notes the homeowner can understand
- Site left clean — signed checklist, not a shrug
Deep dive: 26-point checklist explained · What happens on install day
Use guarantees to compare process, not just promises
The best trust question is not 'who says satisfaction the loudest?' It is 'who tells me what gets measured, what gets documented, and what happens if the installed result misses the agreed scope?' Six Star’s 26-point framing matters because it translates trust into steps a homeowner can actually ask about before signing. That makes guarantees easier to compare against other bids that may sound polished but stay vague about what 'done right' means in practice.

Common questions
What is the 26-point install checklist?
It is Six Star’s documented commissioning standard for qualifying installs — the steps we measure and sign so comfort is not left to “it feels fine.” Ask to see the checklist language on your proposal.
What does the satisfaction guarantee cover?
On qualifying work, we stand behind getting the agreed scope right. Exact terms are stated on your proposal/invoice — we do not hide behind fine print that contradicts the sales conversation.
Are manufacturer warranties the same as Six Star’s guarantee?
No. Equipment warranties come from the manufacturer (registration and maintenance requirements apply). Six Star’s process guarantee covers how we diagnose, install, and commission — ask which warranties apply to your job.
Do you guarantee same-day emergency response 24/7?
No. We guarantee honest timing: same-day when you call before 11 AM on business days. See /emergency for the real policy.
How should I compare your guarantees to another HVAC quote?
Ask whether the other quote defines diagnostics clearly, documents commissioning steps, and explains what 'satisfaction' actually covers after install. The point is not to collect slogans. It is to compare who is putting the install standard, follow-through expectations, and warranty responsibilities into writing before the job starts. A real guarantee should become easier to understand as you ask questions, not harder.
