Get your free estimateThe Dalton Heating & Air Alpharetta Guarantee
When we finish a repair or installation at your home in Alpharetta, you get more than a receipt. You get a written guarantee on every repair we make, a written price before any work starts, and a promise that if the repair fails within a full year, we come back at no charge. That’s not a sales pitch. That’s how we’ve operated since 2003, and it’s written into every job we do. Marco Benitez runs this location, and he holds every technician to The Garrison Standard on each service call. If it’s not done right, we make it right. No fine print, no upgrade fee, no argument.
What’s Covered
- Written price before any work starts. You approve the number before a technician touches your system, and that number does not change unless you approve a change first.
- Written guarantee on every repair. Every service call includes a written guarantee at no extra cost. It’s not an add-on, it’s standard.
- 365-Day Done Right Promise. The repair is guaranteed in writing for a full year. If it fails in that time, we return at no charge.
- Free second visit if the repair fails. If the work does not hold, Dalton Heating & Air Alpharetta comes back and makes it right. You pay nothing for that return trip.
- On-time arrival inside the stated window. We give you a window, and our technicians arrive inside it. If something changes, you hear from us before you have to wonder.
- Clean site, every time. The technician leaves your home the way they found it. No scrap wire, no filter boxes, no boot prints through the house.
- Background-checked, uniformed technicians. You know who is coming before they arrive. Every Dalton tech passes a background check and shows up in uniform with company ID.
- Factory-trained service across nine major brands. We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That covers the vast majority of residential systems installed across Alpharetta, Roswell, Milton, and the rest of north Fulton County.

Our Satisfaction Promise
Here’s what happens if you’re not satisfied with the work. You call us. A live person answers, any hour, any day. You tell us what’s wrong, and we schedule the return visit. Marco Benitez personally reviews every warranty callback that comes through this location. The technician comes back, diagnoses the issue, and fixes it under the written guarantee. There is no deductible, no trip charge, and no prorating. The guarantee period is a full 365 days, not the 30-day or 90-day window you might see elsewhere in the Alpharetta market. If the repair fails on day 200, we’re still coming back at no charge. That’s The Garrison Code: stand behind the work for a full year. If we can’t make it right after a genuine effort, we’ll tell you straight and work out a solution you can accept. What we won’t do is disappear or make you chase us.
Licensed & Insured Backing
A written guarantee is only as good as the company behind it. Dalton Heating & Air Alpharetta is licensed and insured in the state of Georgia. If a technician gets hurt on your property, our insurance covers it, not your homeowner’s policy. If the work causes property damage, our insurance covers that too. And because we’re a Garrison Partners company, every Dalton location is independently owned and operated but bound to the same operating rules. That means you’re not relying on one guy’s handshake. You’re relying on a company that has answered to The Garrison Standard on every job since 2003, with a live-answer phone line staffed 24/7 and a written price before any work starts. The paperwork matters. The license and insurance matter more. They’re the reason the guarantee means something when it counts.
Why the Guarantee Matters in Alpharetta
North Fulton County summers push AC systems hard. It’s not unusual to see a condensing unit on a Milton cul-de-sac running for twelve straight hours in July, or a heat pump in Roswell cycling through a January night. That kind of load exposes weak repairs quickly. A bad capacitor replacement or a sloppy refrigerant recharge, something that’s just not quite right, will show itself within weeks under that strain. Most of our warranty callbacks happen within the first two months after a repair, usually when the first real heat wave or cold snap hits. We know this, and we plan for it. The 365-day window isn’t a marketing number. It’s the period that actually covers a full Georgia cooling season and a full Georgia heating season. If a repair survives both, it’s probably sound. If it doesn’t, we’re back at no charge.
What we see regularly in Alpharetta neighborhoods like Windward, Crabapple, and downtown Alpharetta proper is systems that are aging out. Furnaces from the late 1990s and early 2000s, heat pumps that have been limping along on repeated small fixes. The guarantee gives you time to find out whether a repair is actually holding, rather than crossing your fingers for thirty days and hoping. That’s the difference between a warranty that protects the company and one that protects you.
What the Guarantee Does Not Cover
Be clear on this. Our written guarantee covers our workmanship and the parts we install through our own supply chain. It does not cover damage from storms, flooding, power surges, or someone else working on the system after we leave. It does not cover manufacturer defects in equipment we did not install, though we will absolutely help you file a manufacturer warranty claim if that’s what the situation requires. And it does not cover normal wear on a system that was already near the end of its service life. If your furnace in Alpharetta is 22 years old and the blower motor fails two months after we repaired a different component, that’s not a failed repair. That’s an old furnace. We’ll tell you that plainly before we do any work, because honesty about what a repair can and cannot fix is part of The Garrison Code.
Marco Benitez is specific about this on job sites. “I’d rather lose a job by telling the truth than win one by overselling what a repair will do.” The guarantee is real, but it’s not a replacement for a new system when the old one is done. Part of doing the job by the book is telling you when repair is the wrong call.

After368 Words Our Competitors Won’t Say
Most HVAC companies in the Alpharetta area offer a 30-day or 90-day labor warranty. That’s the industry norm. It’s a narrow window that benefits the company, because most failed repairs show up after the window closes but before the homeowner has fully lost patience. A full year is expensive to offer. It means we eat the cost of callbacks that other companies would charge for. It means we train our technicians to fix things correctly the first time because every callback comes out of our margin, not yours. The 365-Day Done Right Promise costs us money. That’s the point.
Every Dalton Heating & Air Alpharetta technician knows the cost of a callback. Marco Benitez reviews warranty numbers monthly with the team. If a particular technician has repeated callbacks on the same type of repair, he gets retrained. If a particular part fails repeatedly across multiple jobs, we stop carrying that part and switch suppliers. The guarantee creates accountability inside the company, not just reassurance for the customer.
And the written price before work starts is non-negotiable. No technician can start work without your signature on the price. If the job needs more work than expected, the technician stops, calls it in, and gets your approval on the new number before proceeding. You will never get a surprise bill from us. In an industry where the final invoice is sometimes double the verbal estimate, that’s a meaningful difference, and we put it in writing on every job since the day this location opened.
Questions You Should Ask Any HVAC Company in Alpharetta
- Is your labor warranty 30 days or a full year? Ours is a full year, in writing, at no extra cost.
- Do you give the price in writing before work starts? We do. It’s a condition of employment for every technician on our team.
- Is the company licensed and insured in Georgia? We are, and we’ll show you proof if you ask.
- Will I reach a live person if I call after hours? Yes. 24/7, live answer, no voicemail queue.
- Who is actually doing the work? A background-checked, uniformed Dalton technician who arrives inside the stated window.
