Your AC is one of the few machines in your house you only think about when it stops. Then it's 92 degrees, the upstairs feels like an attic, and you need someone who actually knows what they're doing. Novus Mechanical is an air conditioning contractor in Freehold, working across Monmouth County on repairs, replacements and new installs, and every job starts the same way: we measure before we quote.
That second part matters more than it sounds. Most cooling problems get "fixed" by swapping a part and hoping. We diagnose first. Load calculations, static pressure, airflow, refrigerant charge. The numbers tell us what's actually wrong, so the repair holds and the new system is sized for your home instead of guessed from the old box.
This page is the front door to all of it. Pick the service that matches your problem below, or call us and we'll point you the right way.
The service you need depends on whether your system is broken now, worn out, or missing from a room altogether, and the table below routes you to the right page and says what Novus measures first before touching anything.
| Service | When you need it | What Novus measures first |
|---|---|---|
| AC repair | System won't turn on, runs but blows warm, or leaks water by the furnace | Refrigerant charge, airflow, electrical components |
| Central AC replacement | System is past saving, undersized, or costs more to keep alive than to replace | Manual J load calculation for the whole house |
| Mini split installation | A room the central system never reaches: addition, attic, sunroom | Room-by-room Manual J load calculation |
| Mini split repair | An existing ductless head is blowing warm, dripping, or throwing an error code | Refrigerant pressures, airflow, control boards |
| Heat pump repair | A heat pump that both heats and cools stopped doing one or both | Refrigerant side, reversing valve, electrical |
| Heat pump installation | Switching to one system for heating and cooling year round | Manual J load calculation, cold-weather performance |
Novus measures before recommending cooling equipment because a system sized off guesswork short-cycles, never pulls humidity, and wears out early, so every job starts with a load calculation and a static-pressure reading instead of a quote based on the old unit's size. Here's the thing most contractors skip. A new air conditioner can't fix a problem it can't see.
Say your house never cools evenly. One contractor measures the unit, sees it's old, and quotes you a bigger one. Sounds reasonable. Except an oversized AC is its own problem. It cools the air fast, shuts off, and never runs long enough to pull the humidity out. So the house feels clammy at 72 degrees, the compressor wears out from short-cycling, and you paid more for a worse result.
Right-sizing is the fix, and right-sizing takes a Manual J load calculation. That's the industry-standard math for matching a system to your actual home: square footage, insulation, windows, and how much air leaks out. We run it on every replacement. We also test the envelope and the ducts when the symptoms point there, which is what our home energy and HVAC diagnostics work covers.
Why go to the trouble? Two reasons that show up on your bill and in your comfort.
A system sized to the home runs longer, gentler cycles. That pulls more humidity, holds a steadier temperature, and costs less to run. And it cuts callbacks. When the repair is aimed at the real cause and the equipment fits, you're not calling us back in three weeks for the same complaint. That's the whole goal: do it once, do it right.
Our technicians hold the credentials that back this up. NCI Residential HVAC System Performance Technician (#25-142-01), NCI Residential Air Balancer (#25-143-01), and EPA certification #P165BDDE28EAD0701. Those aren't decoration. The performance and air-balancer training is exactly what lets us measure static pressure and airflow and turn the numbers into a system that's verified, not just installed.
Keeping a healthy system healthy is its own thing too. A seasonal check-up catches a weak capacitor or a dirty coil before July does. Our HVAC maintenance plan covers that.
Novus services all major cooling brands in Monmouth County, so you're not stuck shopping for a contractor based on whose name is on your condenser.
If your equipment isn't on that list, call us anyway. The brand on the label matters less than whether the system was sized and installed right, and that we can check on anything.
