What Proper Installation Really Gets You

You get consistent cooling in every room, not just the one closest to the unit. Your monthly electric bills stay reasonable instead of shocking you every August.

The system runs quietly in the background instead of rattling the windows or keeping you awake at night. When something does need attention years down the road, you’re covered by real warranties that actually mean something.

Most importantly, you stop worrying about whether your AC will quit working on the hottest day of the year. That peace of mind is worth more than the few hundred dollars some people think they’re saving by going with the cheapest option.

Flower Hill Air Conditioning Contractors

We Know Long Island Homes

We’ve been handling AC installations throughout Nassau County for years. We understand the specific challenges that come with Long Island homes – from older electrical systems that need upgrades to tight spaces that require creative solutions.

Our technicians are licensed, insured, and trained on the latest equipment from major manufacturers. We’re not the guys who show up in an unmarked van with a business card printed at home.

When you call us, you’re working with a local business that has to maintain its reputation in the community. That means we do the job right the first time, because we’ll be here tomorrow if something goes wrong.

AC Installation Process

Here's Exactly What Happens

First, we come out to assess your home and current setup. We measure spaces, check your electrical panel, examine existing ductwork, and discuss what you actually need – not what costs the most.

You get a detailed estimate that breaks down equipment costs, labor, and any additional work required. No surprises, no “we found something else” charges that double your bill halfway through the job.

Installation day starts with protecting your floors and furniture. We remove old equipment properly, install the new system according to manufacturer specifications, test everything thoroughly, and clean up completely. You get a walkthrough of your new system and all warranty information before we consider the job finished.

The whole process typically takes one day for most residential installations, though larger or more complex jobs might take two days.

Everything's Included in the Job

Your installation includes proper equipment sizing based on your home’s square footage, insulation, and layout. We handle all electrical connections, refrigerant lines, and ductwork modifications needed for optimal performance.

We install both central air systems and ductless mini-split units depending on your home’s needs and your preferences. Every installation includes startup, testing, and calibration to ensure everything operates correctly from day one.

You receive manufacturer warranties on equipment plus our labor warranty on the installation work. We also provide a complete walkthrough of your new system, including thermostat programming and basic maintenance tips that help keep everything running smoothly.

All permits and inspections are handled as part of the service. You don’t need to worry about dealing with the town or scheduling follow-up visits – we take care of those details.

Most residential AC installations take one full day, typically 6-8 hours depending on the complexity of your setup. If we’re installing a central air system in a home that previously had window units, it might take two days because we need to install new ductwork. Ductless mini-split systems usually take 4-6 hours since there’s less involved. We’ll give you an accurate timeframe during the estimate so you can plan accordingly. The key is that we don’t rush the job just to finish faster – proper installation takes the time it takes.
The right size depends on your home’s square footage, ceiling height, insulation quality, window placement, and several other factors. A unit that’s too small won’t cool your home effectively. A unit that’s too large will cycle on and off constantly, wasting energy and not removing humidity properly. We do a proper load calculation during our estimate – measuring rooms, checking insulation, noting which direction your home faces, and accounting for heat sources like large windows or kitchens. This ensures you get a system that’s sized correctly for efficient operation and consistent comfort.
Installation costs vary based on the type of system, size of your home, and complexity of the installation. Central air systems typically range from $3,500 to $8,000 including equipment and installation. Ductless mini-split systems range from $2,500 to $6,000 depending on how many indoor units you need. Factors that affect price include whether electrical upgrades are needed, ductwork modifications, and the efficiency level of equipment you choose. We provide detailed written estimates that break down all costs so you know exactly what you’re paying for before any work begins.
Yes, we handle all permit applications and coordinate required inspections as part of our installation service. Nassau County requires permits for most AC installations, and there are specific requirements for electrical connections, refrigerant handling, and equipment placement. We’re familiar with local codes and inspection requirements, so you don’t need to worry about dealing with the building department or scheduling follow-up visits. The permit costs are included in your estimate, and we make sure everything passes inspection the first time by doing the installation correctly according to local codes.
Central air uses ductwork to distribute cool air throughout your home from one main unit, while ductless systems have individual units mounted in each room or zone you want to cool. Central air provides consistent temperature throughout the house and is often more cost-effective for larger homes with existing ductwork. Ductless systems offer more control over individual room temperatures and work well in homes without existing ducts or room additions. Ductless units are also more energy efficient since you’re not losing cool air through ductwork, but the upfront cost can be higher if you need multiple indoor units.
You get two types of warranties with professional installation. The equipment manufacturer provides warranties on the actual AC unit – typically 5-10 years on parts and sometimes longer on major components like compressors. We provide a separate labor warranty on our installation work, usually 1-2 years, which covers any issues related to how the system was installed. This is important because manufacturer warranties don’t cover problems caused by improper installation. Having both warranties means you’re protected whether the issue is with the equipment itself or how it was installed, and you have clear recourse if something goes wrong.
