AC Installation Process

Here's How We Handle Your Installation

First, we evaluate your space to determine the right system size and type for your home. This isn’t guesswork – proper load calculations ensure your new AC can handle North Hempstead’s summer heat without wasting energy on an oversized unit.

How long does AC installation take in North Hempstead homes?

Most residential AC installations take 6-8 hours for a complete system replacement. If you’re adding central air to a home that never had it, the job typically takes 1-2 days because ductwork installation is involved. Ductless mini-split systems usually take 4-6 hours since there’s no ductwork required. The timeline can vary based on your home’s layout, accessibility, and whether any electrical upgrades are needed. We’ll give you a realistic timeframe during the initial consultation so you can plan accordingly.

What size AC unit do I need for my home?

AC sizing depends on your home’s square footage, insulation, window placement, and local climate factors. A proper load calculation considers ceiling height, number of windows, insulation quality, and how much sun your home gets. In North Hempstead’s humid climate, this calculation is especially important because an oversized unit won’t remove humidity effectively, leaving your home feeling clammy. An undersized unit will struggle during heat waves. We perform these calculations during the consultation to ensure you get exactly the right capacity for efficient, comfortable cooling.

How much does AC installation cost in North Hempstead?

AC installation costs vary based on system type, home size, and installation complexity. Central air systems typically range from $3,000-$8,000 depending on efficiency ratings and ductwork needs. Ductless mini-splits start around $2,500 for single zones. High-efficiency systems cost more upfront but save money on energy bills long-term. Factors affecting price include electrical upgrades, permit fees, and accessibility challenges. We provide detailed written estimates that break down all costs so you know exactly what you’re paying for before work begins.

Do you handle permits for AC installation in North Hempstead?

Yes, we handle all permit applications and inspections required by North Hempstead building codes. HVAC installations typically require permits to ensure safety and code compliance. The permit process includes submitting installation plans, scheduling inspections, and ensuring all work meets local requirements. This is included in our service – you don’t need to visit town hall or coordinate with inspectors yourself. We know local codes and have established relationships with building departments, which helps streamline the process and avoid delays.

What's the difference between central air and ductless AC systems?

Central air conditioning uses ductwork to distribute cool air throughout your home from a single indoor unit. It’s ideal if you already have ducts or want whole-house cooling from one system. Ductless mini-splits have individual indoor units in each room or zone, connected to an outdoor unit. They’re perfect for homes without existing ductwork, room additions, or when you want independent temperature control in different areas. Ductless systems are often more energy-efficient because there’s no duct loss, and installation is less invasive since no ductwork modifications are needed.

What warranty comes with professional AC installation?

You get manufacturer warranties on all equipment – typically 5-10 years on parts and up to 12 years on compressors, depending on the brand and model. Our installation work itself is also warranted to ensure everything was done correctly. Manufacturer warranties only apply when systems are installed by licensed professionals and registered properly. We handle warranty registration and provide all documentation you need for future service. We also explain what’s covered and help coordinate any warranty claims if issues arise. Proper installation is crucial because improper work can void manufacturer coverage.
