The Promise, in One Paragraph
When we finish a job at your home, we stand behind it for 90 days – in writing, no asterisks. If something we did isn’t holding up the way it should, call us. We’ll schedule a return visit, we’ll make it right, and we won’t charge you for it. No forms to fill out, no receipts to track down, no one to argue with. That’s the Keystone Standard, and it’s the same promise on every job we do, coast to coast.
What’s Covered
- Our workmanship: If a duct cleaning, dryer vent clearing, repair, sealing, or sanitizing job we performed isn’t right, it’s covered – full stop.
- Parts we supplied and installed: Any component we sourced and put in as part of your job is covered for the full 90-day window.
- A return visit at no charge: If you call within 90 days with a concern about our work, we come back – no service fee, no diagnostic charge.
- A redo when a repair doesn’t hold: If a sealed joint reopens or a repair fails on our watch within 90 days, we fix it again from scratch.
- Clean-up: We left your home clean when we finished, and we’ll do the same on any return visit.
- Camera re-inspection: We inspect ductwork before and after every job; on a return visit, we bring the camera again so you can see exactly what we see.
What Isn’t Covered
- Damage that happened after we left: A storm, a flood, a pest intrusion, or an accident isn’t something we caused, and it falls outside the workmanship promise – though we’re glad to come look and give you an honest assessment.
- Work done by someone else: If another contractor touched the same area after our visit, we can’t stand behind what we didn’t do. We’ll still look, and we’ll tell you plainly what we find.
- Parts the customer supplied: We install what we source and warrant. If you provided a component and asked us to use it, the part itself isn’t covered, though our labor on it is.
- Normal wear on equipment we didn’t install: An aging furnace blower or a flex duct that was already deteriorating before we arrived isn’t a workmanship issue. If we flagged it on your job report, that note is still on file.
- Problems you chose not to address: If we pointed something out – a cracked fitting, a blocked secondary vent, a section of ductwork that needed attention – and you decided to hold off, that item isn’t covered. It stays on your job record if you change your mind later.
- Equipment or systems outside our scope: We clean, repair, and seal ductwork. A furnace control board or an air handler refrigerant issue is outside our trade. We’ll tell you who to call.
How to Use the Promise
Step 1: Call us at (844) 685-6342, or book online.
A live person answers that number 24 hours a day, every day – not a voicemail, not a callback queue. Tell them you’re calling about a return visit under the 90-Day Done Right Promise.
Step 2: Tell us the job and roughly when it was done.
You don’t need a receipt, an invoice number, or anything in writing on your end. We keep the job on file, and we’ll pull it up while you’re on the phone.
Step 3: We schedule the return visit.
We’ll find a time that works for you and confirm it before we hang up. Most return visits happen quickly – we don’t put promise calls at the back of the line.
Step 4: We make it right.
The technician who returns will review the original job record, inspect with a camera, and correct whatever isn’t right. There’s no fee, no form to sign, and no one for you to convince. That’s the whole process.
Timing
The 90-day window opens on the date of your service and closes 90 days later. That date is on your job record, so there’s no dispute about when the clock started.
If you notice something the day after the window closes, call anyway. We’re not looking for reasons to turn a good customer away. Each location is independently operated, but every one of them honors this promise – it’s part of what it means to carry the Keystone name. Reasonable people work things out, and that’s how we’re built.
