What Proper Installation Gets You

Your AC system works the way it’s supposed to when it’s installed right the first time. You get consistent cooling in every room, not hot spots upstairs and freezing temperatures downstairs.

Energy bills stay predictable because properly sized and installed systems don’t work overtime trying to cool your space. The unit runs efficiently, cycles properly, and doesn’t strain against poor ductwork or incorrect placement.

You avoid the headaches that come with rushed installations. No callbacks for leaks, no mysterious noises at 2 AM, and no surprise failures three weeks after installation. Just reliable cooling when you need it most.

AC Installation Process

Here's How We Handle Installation

We start with an honest assessment of your space and cooling needs. This includes measuring square footage, checking existing ductwork, and evaluating your electrical setup. No guessing, no overselling equipment you don’t need.

Installation day begins with protecting your floors and furniture. We map out the work area, shut off power safely, and remove old equipment if needed. For new installations, we run refrigerant lines, install the outdoor unit, and connect everything according to manufacturer specifications.

The final step involves testing the entire system under load, checking refrigerant levels, and programming your thermostat. We walk through basic operation with you and clean up completely before we leave. Your system is ready to run efficiently from day one.

What's Included in Every Installation

Every AC installation includes proper equipment sizing based on your actual cooling load, not just square footage. We account for insulation levels, window placement, and local climate conditions that affect how hard your system works.

Ductwork evaluation comes standard because even the best AC unit can’t perform with damaged or poorly designed ducts. We identify airflow restrictions, seal leaks, and recommend improvements that actually make a difference in your comfort.

You get permits pulled, inspections scheduled, and all electrical connections handled by licensed professionals. We coordinate with local inspectors and make sure everything meets current codes. The installation includes manufacturer warranties on equipment plus our labor guarantee.

How long does AC installation take in Massapequa homes?

Most residential AC installations take 6-8 hours for a complete system replacement, though this varies based on your specific setup. Straightforward replacements where we’re swapping out an existing unit can often be completed in a single day. New installations requiring ductwork modifications or electrical upgrades may take 1-2 days. We’ll give you an accurate timeline after evaluating your home and won’t rush the job to meet an artificial deadline. Proper installation takes the time it takes.

What size AC unit do I need for my home?

AC sizing depends on much more than just square footage, especially in Long Island’s humid climate. We perform a proper load calculation that factors in your home’s insulation, window placement, ceiling height, and local weather patterns. Oversized units cycle on and off too frequently, creating humidity problems and higher energy bills. Undersized units run constantly and never quite catch up. The right size unit runs efficiently, maintains consistent temperatures, and handles our summer humidity properly.

Do you install both central air and ductless systems?

Yes, we install central air conditioning systems, ductless mini-splits, and commercial HVAC equipment throughout Massapequa. Central systems work well for homes with existing ductwork and whole-house cooling needs. Ductless systems are perfect for additions, older homes without ducts, or when you want zone control in specific areas. We’ll recommend the best option based on your home’s layout, existing infrastructure, and cooling preferences rather than pushing one type over another.

What permits are required for AC installation in Massapequa?

Most AC installations in Massapequa require permits through the Town of Oyster Bay, especially for new systems or major electrical work. We handle all permit applications and coordinate inspections as part of our installation service. This ensures your system meets local building codes and won’t cause issues if you sell your home later. Skipping permits might save money upfront, but it creates problems down the road and can affect your homeowner’s insurance coverage.

How much does professional AC installation cost?

AC installation costs vary significantly based on system type, home size, and complexity of the installation. Basic central air replacement typically ranges from $3,000-$7,000, while new installations requiring ductwork cost more. Ductless systems vary based on the number of indoor units needed. We provide upfront pricing after evaluating your specific situation, so you know exactly what you’re paying before work begins. No surprise charges or hidden fees after we start the job.

What warranty comes with your AC installation work?

All equipment comes with manufacturer warranties that typically cover parts for 5-10 years depending on the brand and model. We provide a separate labor warranty on our installation work, covering any issues related to how the system was installed. This includes refrigerant line connections, electrical work, and system commissioning. If something goes wrong due to installation error, we fix it at no charge. We also offer extended service agreements for ongoing maintenance and priority service calls.
