We Quote Before
We Start. Always.
You will know the cost of the repair or installation before any work begins. We do not add charges at the end of a job that were not in the original quote. If we find additional work during a service call, we explain it, quote it separately, and let you decide.
Quote Before We Work
Repair estimates provided before any work begins. Replacement quotes are itemized line by line so you see exactly what you’re paying for.
No Surprise Add-Ons
If we discover additional work mid-job, we explain it, quote it separately, and wait for your approval. You are never billed for work you didn’t agree to.
Honest System Life Advice
We tell you when a 12-year-old furnace still has life left. We recommend replacement when it’s warranted — not on every service call.
We also handle Peoples Natural Gas & Duquesne Light rebate paperwork on your behalf — at no extra charge.
The contractor who tells you “this furnace has 4 to 5 years of life left — here is what to watch for” builds a longer-term relationship than the one who recommends immediate replacement on every call.
