AC Repairin Freehold, NJ
Your AC is running, but the air coming out of the vents isn't cold. Novus Mechanical repairs air conditioners across Freehold and Monmouth County, and every job starts with a real diagnosis instead of a guess. Too many companies show up, swap the cheapest part they can think of, and hand you a bill. When the same problem comes back two weeks later, you pay again.
That is not how we work.
We measure first. We check the refrigerant charge, the airflow, and the electrical parts before we tell you what is wrong. The fix has to solve the actual problem, not cover it up for a few days. If you want the bigger picture on cooling, our cooling services overview shows everything we handle.
Common AC problems we fix
Most calls we get in a Freehold summer come down to a handful of failures. Here are the ones we see most.
The AC won't turn on. Sometimes it's a tripped breaker or a dead thermostat battery. Sometimes it's a blown capacitor, the small part that gives the motor its kick to start. A capacitor often dies on the first 90-degree day of the year, when the unit works hardest. We find the real cause before we touch anything.
It runs but won't cool. Low refrigerant, a dirty coil, or a failing compressor can all leave you with warm air. Low refrigerant usually means a leak, since AC systems do not burn it off. More on that below.
It's leaking water. A clogged condensate drain backs up and can trip a safety switch that shuts the whole system down. Water near your air handler is worth a call before it reaches drywall or a finished basement.
It's loud. A new grinding, buzzing, or rattling sound is the unit telling you a part is going. Caught early, it's a small repair. Ignored, it can take out the compressor, which is the most expensive part in the system.
Find the real cause, fix it for good
How does Novus find a refrigerant leak?
If your AC is low on refrigerant, topping it off is a temporary patch, not a repair. Refrigerant runs in a sealed loop. If the level dropped, it leaked out somewhere, and the U.S. EPA restricts venting refrigerant on purpose. Adding more without finding the leak just sends your money and the refrigerant into the air.
We hunt the leak down with electronic detectors and visual inspection of the coils, line set, and fittings. Older systems still running R-22 refrigerant are the worst hit, because that refrigerant is phased out and the price keeps climbing. Once we find the leak, we tell you straight whether the repair makes sense or whether the money is better spent on a replacement. Sometimes a small coil leak on a 14-year-old unit is the moment to plan a central AC replacement instead of pouring cash into a dying system.

Coil and drain cleaning
A lot of "broken" air conditioners are dirty, not broken.
The evaporator coil and condensate drain are where summer humidity, dust, and algae build up. A coated coil can't pull heat out of the air, so the system runs longer, costs more, and still leaves the house warm. A clogged drain backs up water and can shut the unit down on a safety switch.
We clean the coils, clear the drain line, and check the airflow that feeds the system. On a Freehold colonial or a 1980s cape with the original ductwork, weak airflow is often the real story behind a coil that keeps freezing or fouling. If the airflow problem runs deeper, our thermal imaging work can show exactly where conditioned air is escaping before it reaches the room. Regular cleaning is also the core of what a maintenance plan covers, which keeps small problems from turning into July emergencies.
Our diagnostic process
We do not start with a part. We start with measurements.
Every repair visit begins with a real diagnostic: refrigerant pressures, airflow across the coil, static pressure in the ducts, and the electrical components that fail most. Our technicians hold NCI System Performance (#25-142-01) and Air Balancer (#25-143-01) certifications from the National Comfort Institute, plus EPA certification (#P165BDDE28EAD0701) to handle refrigerant. That training is the reason we catch the airflow and pressure problems most companies skip.
When we know the real cause, you get the full repair price before any work begins. Parts like a capacitor are priced before we start, so nothing lands on your bill as a surprise. If a repair doesn't make sense on an old system, we say so. We would rather lose the repair than sell you one you don't need. If a heat pump is your cooling source, our heat pump repair page covers that side.
