Question 1

How much does AC installation cost in Westwood, NJ?

Accepted Answer

Central AC installation ranges from $8,500 to $19,500, ductless mini-split installation from $5,500 to $12,500, and AC system replacement from $5,000 to $18,000. Final pricing depends on system size, your home layout, and installation complexity. We provide clear pricing after an in-home assessment.

Question 2

How long does a new AC installation take?

Accepted Answer

A straightforward AC replacement where the ductwork is already in place typically takes one to two days. New installations that require ductwork, electrical upgrades, or structural modifications may take longer. Your technician will provide a timeline specific to your project.

Question 3

What size AC system does my home need?

Accepted Answer

The correct size is determined through a Manual J load calculation that factors in your home's square footage, insulation, window area, orientation, and local climate. An oversized system short-cycles and wastes energy, while an undersized system runs constantly without reaching the set temperature. We perform this calculation for every installation.

Question 4

Should I repair or replace my air conditioner?

Accepted Answer

As a general rule, if your AC is over 10 years old and the repair costs more than half the price of a new system, replacement is usually the better investment. Other factors include refrigerant type (R-22 systems should be replaced), energy efficiency, and how often you have needed repairs in recent years.

Question 5

What is the difference between central AC and a ductless mini-split?

Accepted Answer

Central AC uses ductwork to cool your entire home from a single outdoor unit and indoor air handler. Ductless mini-splits use individual wall-mounted units in each room connected to an outdoor compressor, with no ductwork needed. Central AC is ideal for homes with existing ducts, while mini-splits work well for homes without ductwork, additions, or targeted zone cooling.

Question 6

What SEER rating should I look for in a new AC?

Accepted Answer

SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency. New federal regulations require a minimum of 15 SEER for systems installed in the northern US. Higher SEER ratings (16-20+) cost more upfront but lower your monthly energy bills. We help you find the right balance of efficiency and budget.
