Get your free estimateThe Dalton Heating & Air Hempstead Guarantee
When we finish a repair at your home in Hempstead, you get it in writing. Every job starts with a written price before any work begins, and every repair carries a written guarantee that lasts a full year, not a 30-day window. If that repair fails inside 365 days, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s not an upgrade or an add-on you have to ask for. It’s the baseline for every furnace repair, AC repair, and heat pump job we do in Hempstead, Uniondale, Garden City, and the surrounding Nassau County neighborhoods. Marco Benitez, Owner, holds every tech to The Garrison Standard, which means the guarantee is real, in writing, and backed by a company that has operated since 2003.
What’s Covered
- Workmanship for a full year. If a repair we performed doesn’t hold, we return and make it right at no cost to you, no questions about whether it’s “still under the window.”
- Parts we install. We stand behind every component we put into your system. If a part we supplied fails within the guarantee period, we handle the replacement and the labor to reinstall it.
- Written price before any work starts. You approve the number on paper before a tool comes out of the van. No range, no “we’ll see how it goes,” no surprise line items after the fact.
- Written guarantee on every repair. Every service call ends with the repair documented and the coverage spelled out. You leave with proof, not a handshake.
- Free second visit if the repair fails. Our guarantee includes a return trip. If the work doesn’t hold, Dalton Heating & Air comes back at no charge, period.
- Clean job site. The Garrison Code says leave the site clean. We treat your Hempstead home like we’re working in our own. Drop cloths down, debris out, floors swept.
- On-time arrival. We commit to a window and we arrive inside it. If something outside our control shifts the schedule, a real person calls you, not an automated text.
- Honest diagnosis. If the fix is a $40 capacitor, we tell you it’s a $40 capacitor. We don’t sell you a replacement system because the diagnosis is easy money, and our techs are not paid on what they sell.
- Nine major brands covered. Our techs are factory-trained on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. The guarantee follows the work regardless of brand.
- Background-checked technicians. The person who shows up is a uniformed, background-checked pro. You know who’s coming before they arrive, and you know they’re accountable to The Garrison Standard.

Our Satisfaction Promise
If you’re not satisfied with the work, we don’t consider the job done. Call us and tell us what’s wrong. We send a technician back to evaluate the repair, and if the work didn’t hold or wasn’t done to The Garrison Code, we fix it at no charge under the 365-Day Done Right Promise. If there’s a dispute about what should have happened, we review the written price, the written guarantee, and the documented diagnosis with you, line by line. Marco Benitez built Dalton Heating & Air Hempstead around a simple rule: if it’s not done right, we make it right. That applies to a heat pump installation in East Meadow, a furnace repair near Hofstra, or an AC diagnostic in West Hempstead. You don’t chase us. We pick up the phone, 24/7, and a live person takes the call. No voicemail queue, no ticket number, no “someone will get back to you within two business days.” The Garrison Standard means the guarantee is part of the job, not a separate product you buy.
Licensed & Insured Backing
A guarantee is only as good as the company behind it, and a licensed, insured HVAC contractor in New York is bound by more than a promise. Dalton Heating & Air Hempstead operates as a licensed and insured business, which means our work is subject to state and local code requirements, and your home is protected if something goes wrong on the job. Insurance and bonding aren’t just paperwork; they’re the backup that turns our written guarantee into something you can actually collect on. If a technician is hurt on your property or accidental damage occurs, you’re not left holding the cost. Marco Benitez carries that coverage on every call, for every tech, on every job from AC repair to heat pump installation. It’s the difference between a guy in a truck with a magnet on the door and a company you can hold accountable. And accountability is the whole point of a guarantee.
