AC Installation Process

Here's How We Handle Your Installation

First, a technician evaluates your home to determine the right system size and type for your space. This isn’t a quick estimate – it involves measuring rooms, checking insulation, and understanding your cooling needs. Getting this step right prevents most future problems.

Next comes the actual installation. We handle all permits, remove old equipment if needed, and install your new system according to manufacturer specifications and local codes. This includes proper electrical connections, refrigerant lines, and ductwork modifications if necessary.

Finally, we test everything thoroughly before leaving. You’ll get a walkthrough of your new system, including how to operate it efficiently and what to expect during the first few weeks of operation.

Most residential AC installations take one to two days, depending on the complexity of your setup. A straightforward central air installation in a home with existing ductwork usually takes about 6-8 hours. If new ductwork is needed or you’re installing a multi-zone ductless system, it might take up to two full days. We’ll give you a realistic timeline during the initial assessment so you can plan accordingly. Weather delays or permit issues can occasionally extend the timeline, but you’ll be kept informed of any changes.
The right size depends on several factors specific to your home – square footage, ceiling height, insulation quality, window placement, and local climate conditions. A system that’s too small won’t keep you comfortable during hot summer days. One that’s too large will cycle on and off frequently, wasting energy and failing to remove humidity properly. A proper load calculation takes about 30 minutes and considers all these factors to determine the exact capacity you need. This calculation is included with every installation estimate and ensures you get a system that works efficiently for your specific situation.
Yes, all necessary permits and inspections are handled as part of our installation service. Great Neck Plaza requires permits for most AC installations, and the local codes are specific about electrical connections, refrigerant handling, and equipment placement. We pull all required permits before starting work and schedule any necessary inspections with the local building department. This ensures your installation meets all local requirements and protects you from potential issues if you sell your home later. You don’t need to worry about the paperwork – it’s all taken care of.
Absolutely. Many older homes in Great Neck Plaza don’t have central air ductwork, but there are several good options available. Ductless mini-split systems are often the most practical choice – they provide excellent cooling without major construction work. High-velocity ductwork is another option that uses smaller ducts that can fit in tight spaces. Traditional ductwork installation is also possible in most homes, though it requires more extensive work. During the assessment, you’ll get recommendations for the best approach based on your home’s layout, your budget, and your cooling preferences.
You get both manufacturer warranty coverage on the equipment and a workmanship guarantee on the installation itself. Most AC units come with 5-10 year manufacturer warranties on parts, with longer coverage on major components like compressors. Our installation workmanship is guaranteed for one year, covering any issues related to the installation process. This includes refrigerant leaks, electrical connections, and mounting problems. You’ll receive all warranty documentation at completion, along with instructions for registering your equipment warranty with the manufacturer. Keep these documents safe – you’ll need them for any future warranty claims.
Installation costs vary significantly based on the type of system, your home’s requirements, and any additional work needed. A basic central air installation might start around $3,000-$5,000, while high-efficiency systems or complex installations can cost $8,000 or more. Ductless systems typically range from $2,000-$6,000 depending on how many indoor units you need. The best approach is to get a detailed estimate based on your specific situation. This includes a proper load calculation, assessment of your home’s requirements, and recommendations for systems that fit your budget and cooling needs. No surprises, no hidden fees.
