Everything Included in Professional Installation

Our residential AC installation covers central air systems, ductless mini-splits, and heat pumps. We handle the electrical connections, refrigerant lines, condensate drainage, and all ductwork modifications needed for proper operation.

For Williston Park’s older homes, we often upgrade electrical panels and modify existing ductwork to accommodate modern, efficient systems. We also install programmable thermostats and explain how to maximize your system’s efficiency.

Commercial AC installation includes rooftop units, split systems, and multi-zone configurations for offices, retail spaces, and restaurants. Every installation meets local building codes and manufacturer specifications, protecting both your warranty and your investment.

How long does AC installation take in Williston Park homes?

Most residential AC installations take one to two days, depending on your home’s setup and the system type. Simple central air replacements with existing ductwork often finish in a single day. New installations requiring ductwork modifications or electrical upgrades typically take two days. We’ll give you an accurate timeline during your estimate, and we stick to our schedule. Complex commercial installations or whole-house systems with extensive ductwork can take longer, but we coordinate everything to minimize disruption to your routine.

What size AC system do I need for my home?

System size depends on your home’s square footage, insulation quality, window placement, ceiling height, and local climate factors. We perform detailed load calculations rather than guessing based on square footage alone. Oversized systems waste energy and don’t control humidity properly. Undersized systems run constantly and never cool adequately. Most Williston Park homes need between 2-5 tons of cooling capacity, but the only way to know for sure is through proper assessment. We measure everything and calculate your exact needs before recommending equipment.

Do you install ductless AC systems in older homes?

Yes, ductless mini-split systems work perfectly in older Williston Park homes without existing ductwork. They’re also great for room additions, converted garages, or areas where extending ductwork isn’t practical. Installation is less invasive than central air since we only need to run refrigerant lines and electrical connections between indoor and outdoor units. You get individual temperature control for each zone, which many homeowners prefer. The process typically takes one day for single-zone systems, slightly longer for multi-zone configurations covering multiple rooms.

How much does AC installation cost in Williston Park?

Installation costs vary based on system type, home size, existing infrastructure, and equipment quality. Basic central air replacements with existing ductwork start around $3,000-5,000. New installations requiring ductwork and electrical upgrades range from $5,000-10,000 or more. Ductless systems cost $2,000-4,000 per zone. High-efficiency equipment costs more upfront but saves money long-term through lower energy bills. We provide detailed written estimates that break down all costs so you know exactly what you’re paying for, with no hidden fees or surprise charges.

What permits are required for AC installation in Williston Park?

Most AC installations require permits from the Town of North Hempstead building department. We handle all permit applications and inspections as part of our service. Permits ensure installations meet local building codes and safety requirements. Simple equipment replacements sometimes don’t need permits, but new installations, electrical work, and ductwork modifications typically do. The permit process adds a few days to project timelines but protects you legally and ensures proper installation. We’re familiar with local requirements and maintain good relationships with inspectors to keep everything moving smoothly.

Do you service AC systems after installation?

Absolutely. We provide ongoing maintenance and repair services for all systems we install. Regular maintenance keeps your warranty valid and prevents expensive breakdowns. We recommend annual tune-ups before cooling season starts, but we’re available year-round for any issues that arise. Being local means we can respond quickly when you need service. We keep detailed records of your installation and maintenance history, which helps us diagnose problems faster and recommend the right solutions. Our goal is a long-term relationship, not just a one-time installation sale.
