Fast, Local AC Repair & Installation
When your AC goes down in Hempstead in August, you do not need a callback window that spans three days. You need a technician at your door. We keep technicians stationed across Nassau County, which is why we can typically reach homes in Hempstead, Uniondale, West Hempstead, and Garden City the same day you call. Our standard arrival window is 2 hours, and we hit it.
That speed matters because a dead AC on Long Island is not just uncomfortable – it is dangerous for older adults, young children, and anyone with a respiratory condition. High humidity inside a Hempstead home spikes quickly when the system stops running, and mold can start forming in as little as 24 to 48 hours on damp drywall. A fast repair is a health decision as much as a comfort decision.
What “fast” looks like for us:
- Phone answered by a live person, 24/7 – no voicemail queue
- Same-day appointments for most calls received before 2:00 p.m.
- Technicians carry common parts on the truck – capacitors, contactors, fan motors, thermostats, and refrigerant – so many repairs are finished in one visit
- License and background checked, in uniform, with a name you’ll hear before they arrive
We work on all nine major residential HVAC brands – Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your system is one of those, we have the factory training to diagnose and fix it correctly the first time. If it’s a lesser-known brand, we’ll still take the call and tell you honestly whether a repair is worth making.
What We Check on Every Repair Call
Here’s the sequence a Dalton technician follows on a repair visit, step by step. It’s the same whether the home is in Hempstead, East Meadow, or anywhere else on the route:
- Listen to the symptom. We ask when the system stopped cooling, what sounds or smells you notice, and whether the airflow feels weak or warm.
- Inspect the condenser and air handler. The condenser is the outdoor unit. The air handler is the indoor unit that pushes cooled air through the ducts. We check both.
- Run system diagnostics. We measure refrigerant pressure and line temperatures, check the capacitor and contactor, and test airflow across the evaporator coil.
- Show you what’s wrong. We take photos and point out the failed part or leak. You see what we see.
- Give you a written price. The cost to repair is on paper, split by part and labor, before we turn a screwdriver. If it’s not worth fixing, we’ll say so and give you a written replacement quote instead.
- Perform the repair. We fix the root cause, not just the symptom. A contactor that keeps failing because the system is overamping gets the underlying electrical issue addressed, not just the part swapped.
- Verify the repair. We run the system, measure temperature drop across the coil, and make sure the cycle is completing properly.
- Leave the site clean. No wire clippings, no empty boxes, no grease on the walkway. The Garrison Code says leave it clean, and that means clean.

What AC Repair Costs Near Hempstead
Hempstead homeowners ask us about cost more than anything else. Fair question. Here are the ranges we see most often on repair calls in Nassau County:
| Repair Type | Typical Cost Range |
|---|---|
| Capacitor replacement | $120 – $250 |
| Contactor replacement | $150 – $300 |
| Condenser fan motor | $250 – $550 |
| Refrigerant recharge (topping off the cooling fluid the system needs to reach set temperature) | $180 – $500 depending on the refrigerant type and how much is low |
| Thermostat replacement | $150 – $350 |
| Drain line clearing | $100 – $250 |
| Full system replacement (installation) | $6,500 – $14,000 depending on system size, SEER rating, and ductwork condition |
Those are honest ranges for the Hempstead market. The exact number depends on your system’s age, brand, and what failed. The point is you get a real number in writing before any work begins, not a fuzzy estimate that grows at the door.
Areas We Cover
Dalton Heating & Air serves homeowners across central Nassau County. If you’re in Hempstead, we’re likely 15 minutes away or less. We also cover Levittown, Freeport, Hicksville, East Meadow, Long Beach, Oceanside, and Plainview. In the summer, our trucks run routes through Uniondale, West Hempstead, Roosevelt, and Baldwin as well.
If you’re not sure whether we cover your street, call (516) 559-4840 and ask. A live person answers. You’ll know in 30 seconds.
Should You Repair or Replace Your AC?
The honest answer: it depends on the age of the system and the cost of the repair. A good rule of thumb is the $5,000 test. If the repair costs less than $5,000 and the system is under 10 years old, repair usually makes sense. If the system is over 12 years old and needs a compressor, a new installation is often the smarter money. A Compressor Repair addresses the pump that circulates refrigerant through the system. On an old R-22 unit, a compressor replacement can run $2,500 to $4,000 on its own – money that might be better spent on a new, more efficient system.
We’ll tell you the truth either way. Dalty does not make more money on a replacement than a repair; our dispatch team is not on commission, and Marco Benitez’s standard for the shop is simple: sell the right fix, not the profitable one. If your unit can run reliably with a $180 Capacitor Replacement, that’s the recommendation you’ll get.
AC Installation in Hempstead: What to Expect
A new AC installation is a different job from a repair, and it should be treated that way. When we install a system in a Hempstead home, here’s what happens:
- Load calculation. We measure the home’s square footage, window orientation, insulation levels, and ceiling height to size the system correctly. A unit that’s too big short-cycles and leaves the house humid. Too small and it runs constantly without reaching set temperature.
- Written proposal. You get a fixed price with the equipment model numbers, the SEER rating, the warranty terms, and the install date – in writing before you sign or pay anything.
- Permits and code. We pull any permits the Town of Hempstead requires and install the system to current code. That includes proper disconnect placement and line set insulation.
- Installation day. The crew arrives on time, in uniform, with everything needed to finish the job. Most residential installations are done in a single day.
- System startup and walkthrough. We run the system, confirm it’s cooling to spec, and walk you through the thermostat settings and filter locations. Then we clean up.
The 365-Day Done Right Promise applies to installations the same as repairs. If something is wrong in the first year, we come back and make it right. Free.
Why Homeowners in Hempstead Call Dalton
Most of our calls come from homeowners who have already tried someone else. They called another company, got a voicemail, left a message, and waited. Or the technician showed up, gave a verbal estimate, and the final bill came in hundreds higher. Or the repair held for two weeks and the same problem came back.
The Garrison Standard exists for exactly that reason. Our company was founded in 2003, and the rules we operate under have not changed since: arrive when we say we will, write the price down before starting, fix the root cause, clean up, and guarantee the work in writing for a full year. If the repair fails during that year, we return at no charge. That’s not a guarantee you have to ask for. It’s automatically included on every repair.
Marco Benitez runs the Hempstead location for Dalton Heating & Air. Every technician who shows up at your door works to The Garrison Code, and Marco’s name is on the work. That’s the standard.

Is it cheaper to repair or replace my AC?
