Common Issues
Sometimes, repair is no longer an option; replacement is the better decision.
Old Age and Frequent Repairs
Even if your AC is over a decade old and not programmable, you’ll save time, worry, and money if it breaks down frequently.
High Energy Bills
Older models are more difficult to cool and consume more power. If you install a new energy-efficient system, you could reduce your monthly bills.
Overheating or Non-uniform Temperatures
If you have some rooms that are warm and others that are cool, this could indicate that your current system is underpowered or simply dying. This is where a properly sized new system can correct this.
R-22 Refrigerant Phase-Out
Most older air conditioners have R-22 refrigerant, which has become obsolete and is very expensive. System replacement or a good measure is the best solution.
Damaged or Incompatible Parts
When you have worn or mismatched ductwork, wiring, or major components, a full installation is usually safer and more reliable than a series of ongoing repairs.
AC Installation Cost
One of the most common questions is: “What does an AC installation cost in Long Island?” The answer depends on the type of system, the size of your home, and how complex the installation is.
Basic Central Air Conditioner Installation:
$3000 – $7000
This unit (without significant improvement) has standard installation.
Ductless Mini-Split Installation Pricing:
Depends on Zones
This is an excellent option for ductless homes. The price is based on the number of indoor air conditioning units (or zones) to be installed.
High-Efficiency (Advanced) Systems:
$7,000 to $15,000 and up
These models feature more advanced capabilities and offer enhanced performance, catering to higher-end users. They may be more expensive initially, but they can save you money on energy bills in the long run.
Additional factors to consider when determining AC installation cost are whether or not the installation also requires new ductwork or electrical work, ease of installation (e.g., attics or crawl spaces can complicate installation), local permitting and inspection, and efficiency and brand of the unit you select.
At All Island Comfort, we always provide clear itemized quotes with no hidden charges.
