When You Need AC Installation
Not every AC problem means replacement. Here’s when installation is the smarter move than another repair:
- Your unit is 12 – 15 years old and uses R-22 refrigerant. R-22 was phased out years ago. Refrigerant recharge, which means topping off the cooling fluid your system needs to hit set temperature, now costs more than it should on older units because the refrigerant itself is scarce. Homes in Hempstead built in the 1980s and 1990s often still have these systems running.
- Repair bills totaled $1,000 or more in the last two seasons. A good rule of thumb: if a repair costs more than 30% of the system’s replacement value, that money is better spent on new equipment.
- Rooms heat up unevenly. Homes in the South Hempstead and Uniondale border areas, especially two-story colonials and split-levels, often fight poor airflow in upstairs bedrooms. A properly sized new system with the right blower settings fixes this.
- Your outdoor unit runs constantly but the house never quite cools. That’s often a compressor near the end of its life, or a system that was sized wrong from day one. Both situations point to replacement, not another patch job.
- You’re hearing grinding, rattling, or a hard-start thump when the unit kicks on. Those sounds mean internal wear that most repairs can’t undo. On newer units, we’ll repair it. On older ones, we’ll tell you straight if replacement is the honest recommendation.
If any of these sound like your situation, call (516) 559-4840 and we’ll send a technician to assess it. You’ll get a written price for whatever option you choose.
Our AC Installation Process
Here’s exactly how an installation goes when you call Dalton Heating & Air Hempstead:
- Free in-home assessment. A technician measures your home’s square footage, checks the existing ductwork, tests electrical capacity, and asks about your cooling habits. This takes about 60 – 90 minutes. No charge, no obligation.
- Written quote with equipment options. We present two or three configurations, typically including Rheem, York, and Daikin units depending on your budget and efficiency goals. The price is in writing before you decide anything. No number changes at the door.
- Permit and scheduling. Hempstead’s building department requires a permit for most central AC replacements, and we handle that paperwork. We schedule your install for a day that works for you, arrive inside the stated window, and get to work.
- Installation day. We remove the old equipment, set the new outdoor condenser and indoor coil, flush the refrigerant lines, and connect everything to code. If ductwork needs sealing or replacement sections, we handle that too. We protect floors, wear shoe covers, and haul away every scrap of old equipment.
- Startup testing and walkthrough. We run the system through a full cycle, measure temperature drop at the vents, and show you how to use the thermostat. You get the written guarantee and the 365-Day Done Right Promise in writing before we leave.
AC Installation Pricing in Hempstead
Here’s the honest range for a central AC installation in Hempstead, based on the systems we install most often:
- 3-ton, 14 SEER single-stage system (entry level): $4,800 – $6,500. This replaces a basic older unit with a solid, efficient new one. Good choice for a smaller ranch or cape cod.
- 3-ton, 16 SEER two-stage system (mid-range): $6,800 – $8,800. Two-stage cooling runs at partial capacity on mild days, which uses less electricity and controls humidity better. A strong fit for Hempstead’s humid July and August days.
- 4-ton, 17 – 18 SEER variable-speed system (high efficiency): $9,000 – $11,500. Variable-speed units hold temperature within a degree and are nearly silent. Best for larger homes and anyone planning to stay put for 10+ years.
What changes the price:
- Ductwork condition. If your existing ducts are undersized or leaking, we may need to replace sections or add return air. That can add $1,500 – $4,000 depending on scope.
- Electrical upgrades. Older Hempstead homes with 100-amp panels sometimes need a service upgrade before a new high-efficiency system can be installed. We’ll tell you up front if this applies.
- Equipment brand and efficiency. We quote Rheem, York, and Daikin systems most often because they offer the best balance of reliability and parts availability in our market. Daikin tends to cost a bit more up front but carries longer compressor warranties.
- Access and line-set routing. If your condenser sits in a tight side yard or the refrigerant lines run through a finished ceiling, the install takes longer and costs more. We’ll walk the site and account for all of it in the written quote.
Every Dalton quote is free, and the number we put in writing is the number you pay. Call (516) 559-4840 to schedule yours.

FAQs – AC Installation
How much does AC installation cost in Hempstead, NY?
Most central AC installations in Hempstead run between $4,800 and $11,500, depending on system size, efficiency rating, and whether ductwork or electrical upgrades are needed. A basic 3-ton unit in a smaller ranch or cape cod typically lands around $5,000 – $6,500, while a high-efficiency variable-speed system for a larger two-story home runs $9,000 – $11,500. Call (516) 559-4840 for a free in-home assessment and a written quote with no obligation.
Is it cheaper to repair or replace my AC unit?
If your unit is under 10 years old and the repair is a single component, repair is usually the smarter money. If the unit is 12 – 15 years old, uses R-22 refrigerant, or has needed multiple repairs in the last two years, AC Replacement nearly always costs less over the next five years. A good rule: if the repair quote exceeds 30% of replacement value, replace it. We’ll give you our honest read either way, with both numbers in writing.
Can you install a new AC system the same day?
Installation is usually scheduled within 3 – 7 days of the assessment, not same day, because permits and equipment delivery are part of doing the job correctly. If your system fails during a heat wave and you need cooling immediately, call (516) 559-4840 anyway. In some cases we can install the next day if the equipment is in stock and the permit is already in process.
Do I need a permit for AC installation in Hempstead?
Yes. The Town of Hempstead building department requires a permit for most central AC replacements and new installations. Dalton Heating & Air Hempstead handles the permit application, scheduling, and inspection for you. It’s part of every install quote, and it’s why our written price includes the whole job, not just the equipment swap.
Which AC brands does Dalton install?
We quote Rheem, York, and Daikin systems most often for Hempstead homes. Each has solid parts availability and factory warranties that fit our market. We also service and can install Bryant, Carrier, Trane, Lennox, Goodman, and American Standard if you have a specific preference. Marco Benitez reviews every quote before it goes out to make sure the equipment is sized correctly for the house, not just the budget.
