Get your free estimateThe Dalton Heating & Air Houston Guarantee
When we finish a job at your Houston home, you get more than a repaired AC or a new heat pump. You get it in writing. Every repair we make carries a written guarantee for a full year. If that repair fails inside those 365 days, we come back and fix it at no charge. No prorated calculations, no fine print about which parts qualify, no “that’s a different component” runaround. The price you approve before work starts is the price you pay. That’s The Garrison Standard, and it applies to every single call we run in Houston.
What’s Covered
- Written price before any work starts. You see the full cost on paper before a tool comes off the truck. No verbal estimates, no surprise line items at the end.
- Written guarantee on every repair. Each repair gets a guarantee in writing for a full year. If it fails inside that window, the return visit is free.
- Free second visit if the repair fails. We don’t charge you twice for the same problem. If our work doesn’t hold, the follow-up call is on us.
- 365-Day Done Right Promise. A full year of coverage on our workmanship, not a 30-day window that expires before Houston’s next heat wave tests the system.
- On-time arrival inside the stated window. We give you a window before we show up, and we arrive inside it. If something shifts, a live person calls you.
- Background-checked, uniformed technicians. You know who’s coming before they ring the bell. Every tech is background-checked and shows up in a Dalton uniform with identification.
- Clean job site when we leave. The work area looks the way we found it, minus the broken part. We haul off old components and packaging.
- Parts handled correctly for nine major brands. We’re factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard systems, so the right part goes in the first time.

Our Satisfaction Promise
If you’re not satisfied with the work, call us. A live person answers, 24 hours a day, seven days a week, no voicemail queue and no callback window. Tell us what’s wrong. We send a tech back to look at it. If the repair didn’t hold, the second visit is free, no questions and no forms to fill out first. If we made a mistake, we own it and we fix it. Marco Benitez runs this Houston location, and he stands behind what leaves the truck. The make-it-right process is simple: you call, we return, we fix it, and the paperwork reflects what happened. That’s The Garrison Code in practice: arrive inside the window, price it in writing, do the job by the book, leave the site clean, and stand behind the work for a full year.
Licensed & Insured Backing
Paper guarantees matter, but the paperwork behind the company matters more. Dalton Heating & Air Houston is licensed and insured in Texas. That means if something goes wrong on the job, you’re not left holding the cost. Our techs work on live electrical, gas connections, and high-pressure refrigerant lines, and the insurance backing protects your home while they do it. Anyone can print a warranty card. It’s the license and insurance that make that guarantee enforceable. Ask to see either one when we arrive. We’ll show you.
What The Garrison Standard Means on Every Job
Dalton Heating & Air Houston is a Garrison Partners company, founded in 2003. That network holds every location to the same operating rules, called The Garrison Code. Here’s how it plays out on a Houston service call:
- Arrive inside the stated window. We tell you when we’re coming, and we’re there.
- Price in writing before starting. You approve the number before we touch the system.
- Do the job by the book. Factory procedures for all nine major residential brands we service.
- Leave the site clean. No scrap metal, no packaging, no footprints through the attic.
- Stand behind the work for a full year. The 365-Day Done Right Promise applies to every repair, every time.
Why a Full-Year Guarantee Matters in Houston
Houston HVAC systems work harder than systems almost anywhere else in the country. A hundred-degree August afternoon puts stress on a compressor that a mild-climate unit never sees. A furnace that runs three months a year in the Midwest runs six months here, cycling through humidity swings and salt air if you’re near Galveston Bay. A 30-day repair guarantee might expire before the next weather shift actually tests it. A full year means your AC repair gets pushed through a real Houston summer and your furnace repair through a real Houston winter. If it survives both, it was done right. If it doesn’t, we come back free.

AfterThe Nine Brands We Service Under This Guarantee
Our techs are factory-trained on the residential lines from Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters for the guarantee because each brand engineers its equipment differently. A Trane heat pump uses different controls than a Goodman. A Lennox furnace sequences its inducer and igniter differently than a Rheem. When a tech knows the factory spec, the repair holds. When the repair holds, the guarantee never gets tested. And when it doesn’t hold, we’re on the hook for the return trip, so we have every reason to do it right the first time.
How the Second-Visit Guarantee Works
Say we replace a capacitor on your condenser in June. In October, the same capacitor fails. You call. A real person answers. We schedule the return visit at no charge, and we cover the part and the labor to make it right. You don’t pay a second diagnostic fee, you don’t pay for the part again, and you don’t wait through a callback queue. The repair is guaranteed in writing for a full year. If it fails in that time, we return at no charge. That’s the entire promise, stated in plain terms.
Service Areas Across Houston
We run calls across Houston and the surrounding communities, from Katy to Pasadena, The Woodlands to Sugar Land. Whether you’re in a 1970s ranch in Spring Branch with an original duct layout or a newer build in Cypress with a high-efficiency heat pump, the same guarantee applies. Same written price rule. Same full-year coverage. Same live person answering the phone. The zip code changes. The standard doesn’t.
