The difference is in the details. Proper load calculations mean your system runs efficiently without overworking. Quality installation means fewer repairs down the road. And local service means we’re here when you need us, not three towns over with a two-week wait time.

Our AC Installation Process

Straightforward Installation, No Surprises

First, we come to your home for a proper assessment. This isn’t a quick walkthrough. We measure your space, check your electrical system, examine your existing ductwork, and calculate the exact cooling load your home needs.

Then we provide a clear, written estimate that breaks down equipment costs, labor, and any additional work needed. No hidden fees or surprise charges later. You’ll know exactly what you’re paying for before we start.

Installation day, our team arrives on time with all the equipment and materials needed. We protect your floors and furniture, install your new system according to manufacturer specifications, and test everything thoroughly before we leave. We clean up completely and walk you through your new system’s operation.

After installation, we’re still here. We provide warranties on both equipment and our work, plus ongoing maintenance to keep your system running efficiently for years to come.

Everything You Need, Done Right

Our AC installation service covers everything from central air systems to ductless mini-splits. We handle residential and commercial installations, working with the equipment that makes sense for your space and budget.

Every installation includes proper load calculations, electrical connections, refrigerant line installation, and thorough system testing. We work with quality manufacturers and can help you choose between different efficiency levels based on your priorities and budget.

For East Hills homes, we often recommend high-efficiency systems that handle our humid summers while keeping energy costs reasonable. We also install ductless systems for additions, older homes without existing ductwork, or spaces that need individual temperature control.

Our installations meet all local codes and manufacturer requirements. We pull permits when needed and coordinate inspections. You don’t have to worry about the technical details – we handle all of that so your installation goes smoothly from start to finish.

Most residential AC installations take one to two days, depending on your home’s setup and the type of system you’re installing. A straightforward central air replacement where ductwork is already in place usually takes one full day. If we need to install new ductwork, add electrical circuits, or work around structural challenges, it might take two days. Ductless mini-split systems are often faster, sometimes completed in just a few hours for single-zone units. We’ll give you a realistic timeline during your estimate so you can plan accordingly.
The right size depends on several factors specific to your home: square footage, ceiling height, insulation quality, window placement, and how many people typically occupy the space. We perform detailed load calculations that account for East Hills’ climate and your home’s unique characteristics. Many homeowners think bigger is better, but an oversized unit actually works less efficiently and doesn’t remove humidity properly. An undersized unit will struggle to keep up on hot days. Our assessment ensures you get exactly the right capacity for optimal comfort and efficiency.
Yes, most AC installations in East Hills require permits, especially if electrical work is involved or if you’re installing a completely new system. We handle all permit applications and scheduling inspections as part of our service. This protects you by ensuring the work meets local building codes and gives you documentation for insurance purposes or future home sales. The permit process typically adds a few days to the timeline, but it’s worth it for peace of mind and legal compliance.
Installation costs vary based on system type, home size, and complexity of the installation. Central air systems typically range from $3,000 to $8,000 including installation, while ductless mini-splits might cost $2,000 to $5,000 depending on how many zones you need. Factors that affect price include whether new ductwork is needed, electrical upgrades, equipment efficiency ratings, and any structural modifications required. We provide detailed written estimates that break down all costs so you know exactly what you’re paying for before we start work.
Central air uses ductwork to distribute cool air throughout your home from one main unit, while ductless systems have individual units in each room or zone connected to an outdoor compressor. Central air works well for whole-home cooling and is often more cost-effective for larger homes with existing ductwork. Ductless systems offer individual room control, work great for additions or older homes without ducts, and can be more energy-efficient since you only cool occupied spaces. The best choice depends on your home’s layout, existing infrastructure, and how you use your space.
Regular maintenance keeps your system running efficiently and extends its lifespan. Change your air filter every 1-3 months depending on usage and filter type. Keep the outdoor unit clear of debris, leaves, and vegetation. Schedule professional maintenance annually to check refrigerant levels, clean coils, inspect electrical connections, and catch small issues before they become expensive problems. We offer maintenance plans that include regular tune-ups and priority service. Most manufacturers also require professional maintenance to keep warranties valid, so it’s worth staying on top of.
