What's Included in Every Installation

Every installation includes proper system sizing to match your space. Oversized units waste energy and create humidity problems. Undersized units run constantly and never reach comfortable temperatures.

You get professional ductwork evaluation and modifications if needed. Leaky or poorly designed ducts can waste up to 30% of your cooling capacity. The installation includes electrical work to code, permits when required, and cleanup afterward.

Malverne homes often need specific considerations for older electrical systems or unique layouts. We handle these challenges routinely, ensuring your new AC integrates properly with your home’s existing systems without surprises or shortcuts.

Most residential AC installations take 4-8 hours for a complete system replacement. Simple unit swaps can be faster, while first-time installations with new ductwork take longer. The timeline depends on your home’s layout, electrical requirements, and whether permits are needed. Malverne’s older homes sometimes require additional electrical work, which can extend the timeline. You’ll get a clear timeframe estimate before work begins, and we work efficiently to minimize disruption to your day.
AC sizing depends on square footage, ceiling height, insulation quality, window placement, and local climate factors. A professional load calculation determines the right capacity measured in tons or BTUs. Bigger isn’t always better – oversized units cycle on and off frequently, wasting energy and failing to remove humidity properly. Long Island’s humid summers make proper sizing especially important for comfort. We measure your space and calculate the exact capacity needed for efficient operation and consistent comfort throughout your home.
Permit requirements depend on the scope of work and local building codes. Simple unit replacements using existing electrical and ductwork typically don’t require permits. New installations, electrical upgrades, or major ductwork modifications usually do. Malverne follows Nassau County building codes for HVAC work. Licensed contractors handle permit applications and inspections when required. Working without proper permits can create problems during home sales or insurance claims. We determine permit requirements during the initial evaluation and handle the paperwork process.
Installation costs vary based on system type, home size, existing infrastructure, and complexity of the job. Basic central air installations start around $3,000-$5,000 for smaller homes. Larger homes or high-efficiency systems cost more. Ductless mini-split systems range from $2,000-$6,000 depending on the number of zones. First-time installations requiring new ductwork or electrical upgrades cost more than simple replacements. You get upfront pricing before work begins, including all labor, materials, and permits. No surprise charges or hidden fees after the job starts.
Central air uses ductwork to distribute cool air throughout your home from a single indoor unit. It’s ideal for whole-house cooling and works well with existing forced-air heating systems. Ductless mini-splits use individual indoor units in each room or zone, connected to an outdoor compressor. They’re perfect for homes without existing ductwork, room additions, or zone-specific cooling needs. Ductless systems offer more precise temperature control and can be more energy-efficient since you only cool occupied spaces. The choice depends on your home’s layout, existing systems, and cooling preferences.
Basic maintenance includes changing filters monthly during peak usage and keeping the outdoor unit clear of debris. Schedule professional maintenance annually before cooling season starts. This includes cleaning coils, checking refrigerant levels, testing electrical connections, and inspecting ductwork. Long Island’s coastal environment can be tough on outdoor units, so regular cleaning helps prevent corrosion and efficiency loss. Most manufacturers require annual professional maintenance to keep warranties valid. We provide a maintenance schedule and can handle ongoing service needs to keep your system running efficiently for years.
