Central AC Replacementin Freehold, NJ
Your central air is fifteen years old, louder every summer, and the last repair felt like throwing money at a system on its way out. The real question is what size to put back.
Novus Mechanical replaces central air systems across Freehold and Monmouth County. Before we quote, we measure your home with a Manual J load calculation and a blower door test, so the new system is sized to your house instead of guessed from the old one. You get one fixed price and approve it before any work begins.
Should You Repair or Replace Your AC?
When a big repair lands on an older system, the real question is whether you are fixing it or feeding it.
If your AC is under about ten years old, a repair is usually the smart call, and we will tell you so. Once a system passes twelve to fifteen years, runs on old R-22 refrigerant, or needs a repair worth more than about a third of a new system, replacement usually wins over the next few years.
Novus lays out both numbers honestly. We would rather size you a system that lasts than sell one more repair on a unit that is done. If a repair is the better value, we say that. See how we handle AC repair when that is the right call.
And if you are replacing anyway, it is worth knowing whether a heat pump fits your home before you default to the same thing you had.
Installed right, not just swapped in
Why We Size It Right Before We Quote
Most contractors replace your AC with the same size that is already there. That size was probably a guess the first time, and copying it just repeats the mistake.
Oversizing is one of the most common mistakes in the trade, and the U.S. Department of Energy backs this up: a system that is too big cools the air before it removes the humidity, so you end up cold and clammy, while the constant on-off cycling wastes energy and wears the equipment out early.
So before we quote a replacement, we measure. A Manual J load calculation tells us exactly how much cooling your home needs, room by room, the sizing method ENERGY STAR tells contractors to use instead of eyeballing it. A blower door test shows how leaky the house is, which changes the answer. Then we size the new system to those numbers. It is the cheapest part of the whole project and the one that decides whether everything after it actually works.

Sized to the number, not a guess
What the Right Size Actually Changes for You
A right-sized system is not about the number on the box. It is the bedroom that finally cools, the humidity that drops, and the unit that is not grinding itself to death by July.
Oversized equipment blasts cold air, shuts off, and leaves the room damp. The right size runs longer and quieter, holds an even temperature, and lasts the years it is rated for.
