We put it in writing before we pick up a tool. That’s the whole point of The Garrison Standard, and it applies to every AC repair, heat pump installation, and furnace repair we do in Dallas. The price is on paper before work starts. The repair is guaranteed in writing for a full year. If it fails in that time, we return at no charge. That’s not a promotion and it’s not an upgrade. It’s how Dalton Heating & Air Dallas has operated since 2003, and Marco Benitez, Owner, enforces it on every single job his team runs.
What’s Covered
- Workmanship on every repair. Every repair we make is guaranteed in writing for a full year under our 365-Day Done Right Promise, and if it fails in that window, we come back and fix it at no charge.
- Parts and equipment we install. We stand behind the components we put in, and we handle the legwork of coordinating with the manufacturer if a part is defective out of the box.
- Clean site, every time. The Garrison Code requires our technicians to leave your Dallas home the way they found it, no condensate drips, no wire clippings, no filter wrap left in the flower bed.
- On-time arrival inside the stated window. Our background-checked, uniformed technicians commit to a window before they roll the truck, and we notify you who’s coming before they arrive.
- Written price before any work begins. You get the full price in writing, always included, never a surprise. You approve it before we start. If the scope changes, we re-write the price before touching anything new.
- Factory-trained work across nine major brands. We service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The repair standard doesn’t drop because the brand changes.

Our Satisfaction Promise
If a repair doesn’t hold, we don’t debate it. The repair is guaranteed in writing for a full year, and if it fails in that time, we return at no charge. No diagnostic fee game, no re-booking runaround. You call the number, a live person answers, and we schedule the return visit. That second visit is free because the first one was supposed to be right. Marco’s rule on this is simple: a callback is our mistake to own, not your bill to carry. If you’re ever not satisfied with how a job went, call us and ask for Marco directly. The Garrison Code says stand behind the work for a full year, and that’s what happens. We would rather redo a repair at our cost than leave a Dallas homeowner wondering if their AC will survive the next 100-degree week. The promise is the product, which is why it’s printed on every invoice.
Licensed & Insured Backing
A guarantee is only as strong as the company standing behind it. Dalton Heating & Air Dallas is a licensed and insured HVAC contractor serving Dallas, TX. The licensing means our technicians have passed the state’s required exams and operate under Texas HVAC regulations. The insurance means if something goes wrong on your property, you’re protected financially, not left to argue with an uninsured operator. Paying a door-knocker with no paper is a gamble with your compressor and your liability. We carry what’s required to do the work properly, and our technicians are background-checked before they ever put on a Dalton uniform and step onto your driveway. Marco has held that line since 2003, and The Garrison Standard makes it a condition of operation, not a suggestion.
How the 365-Day Done Right Promise Works
Most contractors offer a 30-day or 90-day labor window and call it generous. We cover our repair workmanship for a full year. Here’s the process in plain terms:
- Day one. We diagnose the issue, write the price, get your approval, and complete the repair.
- The paperwork. You receive a written guarantee on the repair with the coverage terms spelled out, not implied over a handshake.
- If it fails. Call (254) 280-5320. A live person answers, 24/7. We schedule a return visit at no charge.
- The standard. We diagnose what went wrong, fix it correctly, and the one-year coverage continues from that point. No pro-rated nonsense, no “that part isn’t covered” fine print games on our workmanship.
The only thing we ask is that you call us first. We can’t make it right if we don’t know it went wrong. And we want to know, because a failed repair in a Dallas August isn’t a minor inconvenience. It’s a health risk in a house that can hit 95 degrees by noon without cooling.

AfterWhat’s Not Covered (in Plain Language)
We’re direct about this because a guarantee with hidden exclusions isn’t a guarantee, it’s a brochure. Here’s what falls outside our workmanship coverage:
- Normal wear and tear on unrelated components. If we repair your blower motor and six months later your capacitor fails, that’s a different part with a different history, not a failed repair.
- Damage from power surges, flooding, or animal intrusion. A squirrel that chews through thermostat wire in your attic didn’t read our warranty terms. We’ll fix it, but the workmanship guarantee applies to what we originally touched.
- Neglected maintenance that causes a new failure. A filter clogged solid for six months can kill a blower motor we didn’t touch. We flag maintenance needs on every visit, in writing, because we’d rather prevent that call than bill it.
- Manufacturer part warranties. Parts carry their own manufacturer coverage. We help you file those claims and do the labor to swap a defective part under warranty, but the part warranty itself comes from the brand, not from Dalton Heating & Air Dallas.
If you’re ever unsure whether something falls under our guarantee, call (254) 280-5320 and ask. A live person answers and gives you a straight answer. That’s how we’ve handled warranty questions since 2003, and it’s not changing.
Why The Garrison Standard Matters in Dallas
Dallas HVAC work is unforgiving. Systems run hard from May through September, and a sloppy repair shows itself fast when the attic hits 130 degrees. The Garrison Standard exists because Marco saw what happens when contractors rush jobs to chase the next call. So Dalton Heating & Air Dallas runs every job under The Garrison Code: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. That code isn’t a marketing line. It’s the operational checklist every technician signs off on before leaving your home. When a company has been operating under that standard since 2003, the guarantee isn’t a risk calculation, it’s a habit.
What Should You Ask Any HVAC Contractor About Their Guarantee?
Before you hire anyone in Dallas, ask these three questions. The answers will tell you more than any review could:
- “Is the repair guarantee in writing, and for how long?” If they say “30 days” or “we stand behind our work” without a number, walk away. Ours is one full year, in writing, on every repair.
- “If it fails, do I pay for the return visit?” If the answer is anything other than a flat “no,” that guarantee is a coupon, not a promise. Our return visit is free, full stop.
- “When will I see the price in writing?” The correct answer is “before any work begins.” If they want to start before pricing, you’re about to fund a surprise. Dalton Heating & Air Dallas writes the price first, every time, no exception.
Those three questions will filter out most of the contractors in the Dallas metro. If you’d like to hear our answers directly, call (254) 280-5320 and ask for Marco. He enjoys that conversation.
Schedule a Repair Backed by a Real Guarantee
When your AC fails in July or your furnace quits on a January night, you need two things: a tech who can fix it today and a guarantee that the fix holds. Dalton Heating & Air Dallas provides both. Background-checked, uniformed technicians. A written price before any work starts. A written guarantee on every repair. A free return visit if the repair fails within a full year. And a live person answering the phone 24/7, including holidays, because HVAC systems don’t check the calendar before they fail.
Call (254) 280-5320 now. Tell us what the system is doing, or not doing, and we’ll get a technician to your Dallas home with the parts to make it right. The guarantee starts the moment the repair is complete, and it’s good for a full year. That’s the Dalton standard.
