Our AC Installation Process

Here's How Your Installation Works

First, we evaluate your space to determine the right system size and type for your home or business. We’ll measure rooms, check existing ductwork, and discuss your cooling needs and budget.

You’ll receive a written estimate that breaks down equipment costs, labor, and any additional materials needed. No surprises or hidden fees after the work starts.

On installation day, we arrive with all necessary equipment and materials. We protect your floors and furniture, install your new system, test everything thoroughly, and clean up completely before leaving. You’ll get a walkthrough of your new system and information about warranty coverage.

Most residential installations complete in one day. Larger commercial projects or homes requiring new ductwork may take longer, but you’ll know the timeline upfront.

What's Included In Your Installation

Every installation includes proper system sizing based on your space, not guesswork. We handle all electrical connections, refrigerant lines, and ductwork modifications needed for your specific setup.

We provide both residential and commercial installation services, including central air systems, ductless mini-splits, and heat pumps. For homes without existing ductwork, ductless systems provide efficient cooling without major construction.

All installations come with manufacturer warranties on equipment and workmanship guarantees on the installation itself. We also provide guidance on maintenance schedules to keep your system running efficiently and prevent premature breakdowns.

Most residential AC installations complete in 6-8 hours, typically finishing in one day. The timeline depends on your specific setup – replacing an existing central air system with similar ductwork goes faster than installing a completely new system. Ductless mini-split installations usually take 4-6 hours since they don’t require extensive ductwork. Commercial installations or homes needing significant ductwork modifications may take 2-3 days. During your estimate, you’ll get a clear timeline based on your specific project requirements.
AC sizing depends on your home’s square footage, insulation quality, window placement, and ceiling height – not just square footage alone. A unit that’s too small won’t cool effectively, while an oversized unit cycles on and off frequently, wasting energy and creating humidity problems. We perform a load calculation during your consultation, measuring rooms and evaluating factors like sun exposure and insulation. This ensures you get a system that cools efficiently without running constantly or driving up your electric bills.
Yes, ductless mini-split systems work perfectly for older Stewart Manor homes without existing ductwork. These systems don’t require major construction or wall demolition – just small holes for refrigerant lines connecting outdoor and indoor units. You can cool specific rooms or zones without the expense of installing full ductwork throughout your home. Ductless systems also offer excellent energy efficiency and quiet operation. Many homeowners choose ductless for additions, converted spaces, or homes where traditional ductwork installation would be too disruptive or expensive.
Central air uses ductwork to distribute cool air throughout your entire home from one main unit, while ductless systems have individual indoor units in each room or zone you want to cool. Central air works well if you already have ductwork and want whole-house cooling with one thermostat. Ductless systems offer more control – you can set different temperatures in different rooms and only cool spaces you’re using. Ductless installation costs less if you don’t have existing ductwork, since you avoid the expense of installing ducts throughout your home.
AC installation costs vary based on system type, size, and complexity of the installation. Basic central air replacement where ductwork already exists typically costs less than new installations requiring ductwork modifications. Ductless systems often cost less to install than central air if you don’t have existing ducts. Commercial installations vary widely based on building size and requirements. During your consultation, you’ll receive a detailed written estimate breaking down equipment, labor, and any additional materials needed. This way you know exactly what you’re paying before any work begins.
Yes, all installations include manufacturer warranties on the equipment itself, typically 5-10 years depending on the brand and model you choose. The installation work also comes with a workmanship guarantee covering any issues related to the installation process. This means if something goes wrong due to installation error, it gets fixed at no charge to you. You’ll receive all warranty documentation after installation completion, including manufacturer contact information and warranty registration details. Regular maintenance helps keep warranties valid and your system running efficiently for years.
