Pick what your house needs and the price moves as you go. These are real ranges from real Monmouth County jobs, built from what we actually pay our suppliers, and a Novus job is never just an equipment swap.
What are we replacing or adding?
The biggest single choice here. One costs less today, the other costs less every winter after.
Finished, heated space. A rough number is fine.
Each room gets its own indoor unit and its own temperature.
Every level is installed and commissioned the same way. This is the box, not the workmanship.
Tap what sounds like your house. You do not need to know what fixes it.
Anyone can swap a box for the box that was there before. That is how houses end up with equipment two sizes too big, short-cycling all summer and never pulling the humidity out. Here is what happens on every Novus job, and it is already inside the number above.
Almost every contractor sizes your new system by reading the label on the old one. That only works if the old one was right, and most were oversized to begin with, so the mistake gets copied every fifteen years. We measure instead: room by room, windows, insulation, which way the house faces, how much air leaks out.
Every jobWe seal a calibrated fan into a doorway and measure exactly how much air your house leaks. That one number decides how much heating and cooling you actually need, which makes our sizing a measurement rather than an opinion. Most companies in this county do not own the equipment to do it.
Every jobSame idea as a doctor taking your blood pressure, done on your ductwork. High static pressure is the reason a brand-new system can still feel weak and still burn out early, and you cannot see it, hear it, or guess it. You have to put gauges on it. If we find it, you know before you buy anything.
Every jobNew equipment does not arrive working correctly. It arrives working approximately. At startup we verify refrigerant charge, airflow and real delivered capacity against the manufacturer's own targets, then hand you the report. Ask any contractor for their commissioning numbers on your last install.
Every jobThe builder above is the same numbers with your house plugged in. This table is here so you can read them without touching anything, and so a search engine can too. All figures are installed prices.

Prices last updated August 24, 2026. Rebuilt from real supplier invoices, not a national average.
Because nobody has measured your house yet. The range narrows to a single fixed price after the Manual J load calculation and the static pressure test, and that price is in writing before any work starts.
No, the visit and the written price that comes out of it are free, and nothing gets signed on the day.
Yes. One year of labor warranty from Novus, plus the manufacturer's warranty on the equipment itself.
You get the breakdown for your house by email. If it looks close, the next step is a visit to measure properly, and that is when the range becomes one fixed price. If you would rather talk it through first, call (848) 288-1133.
Usually because the other number does not include measuring your house. Sizing off the old equipment costs nothing and takes ten minutes, so a company that does it can quote lower. If the old system was oversized, and most were, that mistake gets installed again and you live with it for fifteen years. Our price has the load calculation, the blower door test, the pressure testing and the commissioning in it. That is the difference, and it is the whole reason we do this.
Because the equipment now costs us about the same, and a heat pump cools exactly like an air conditioner while also heating. For most homes here it is simply the better buy, so it is priced to be picked. Your existing furnace stays on as backup for the coldest nights.
Because a flex-heavy rebuild and an all-metal one are genuinely different jobs, and which one your house needs comes out of the duct design rather than out of a phone call. The bottom of that range is the flex build, the top is all metal with insulated trunk lines. It is per system, so a house with separate upstairs and downstairs units is double.
The range above is honest, but it is still a range. Send it to yourself and we will follow up with a written breakdown for your specific house, sized properly, with the price fixed before any work starts.
About these numbers. They are installed prices for Monmouth County, built from what Novus actually paid its suppliers on recent jobs rather than from a national average. They are not a quote and they are not binding. A few things genuinely cannot be seen from outside a house: an undersized electrical panel, asbestos, structural work. Those are not included, and here is the part that matters: if we find one, you get a written price for it and you decide before we touch it. Nothing gets added to a final bill that you did not agree to first. The only number that counts is the one on a written proposal after we have measured your house.
