Your AC is running, but the air from the vents isn't cold. AC repair is the work of finding why an air conditioner quit cooling and fixing the real cause, not the cheapest part on the truck. Novus Mechanical repairs air conditioners across Freehold and Monmouth County, and every repair starts with a measurement, not a guess. Plenty of companies show up, swap a part, and hand you a bill. Two weeks later the same problem is back, and you pay twice.
We measure first. A Novus technician checks the refrigerant charge, the airflow, and the electrical parts before naming a fix. Improper setup and wrong sizing can cut an air conditioner's efficiency by up to 30%, according to ENERGY STAR, so a guess gets expensive fast. The repair has to solve the real problem, not hide it for a week. Our cooling services overview lays out everything Novus handles around Freehold.
Most summer cooling calls in Freehold trace back to four failures, and Novus measures the system to tell them apart before recommending a fix. A botched repair can cut cooling efficiency by up to 30%, according to ENERGY STAR, so guessing gets expensive. A capacitor often quits on the first 90-degree day, when the 91-degree design heat of Climate Zone 4A hits Monmouth County.
| Symptom | Likely cause | What Novus checks first |
|---|---|---|
| AC won't turn on | Tripped breaker, dead thermostat battery, or a blown capacitor | Breaker, thermostat battery, capacitor |
| AC runs but won't cool | Low refrigerant (almost always a leak), a dirty coil, or a failing compressor | Refrigerant charge, coil condition, compressor amp draw |
| Water is pooling near the unit | A clogged condensate drain that tripped the float switch | Drain line flow and the float switch |
| A new grinding or buzzing noise | A failing part: cheap to fix caught early, but ignored it can take out the compressor | Motor bearings, blower wheel, contactor |

A refrigerant leak is a breach in the sealed loop that carries cooling through your air conditioner. Topping off the charge without sealing the breach is a patch, not a repair. Here is how we find the leak. First, we measure the refrigerant charge against the system's target and confirm the loss. Second, we trace the source with electronic detectors across the coil, line set, and fittings. The U.S. EPA restricts venting refrigerant on purpose, and older systems on R-22 get hit hardest, because the EPA banned all R-22 production as of January 1, 2020. In practice, a recharge on a phased-out R-22 system rarely pays off, so a small coil leak on a 14-year-old unit is often the moment to plan a central AC replacement instead of another recharge.

A coil freezes or fouls when airflow across the air conditioner drops too low. A lot of AC units around Freehold are dirty, not broken. The evaporator coil and condensate drain collect summer humidity, dust, and algae until the coil cannot pull heat from the air. Here is how we fix the real cause. First, we clean the coil and clear the drain line. Second, we measure airflow and static pressure across the system using MeasureQuick. Airflow is where Freehold's housing stock matters. In the Stonehurst and Monmouth Heights split-levels off Route 9, for example, the original ductwork now runs 55 to 60 years old, undersized and leaky, which starves the coil. On a 1980s colonial the weak return air does the same. The diagnostic that finds the fault comes with a full price before any repair starts, and our thermal imaging shows where conditioned air escapes.
An AC diagnostic is a measured inspection of the whole cooling system, not a parts swap. Novus does not start with a part. We start with measurements, and we run the same sequence on every Freehold repair visit.
Our technicians hold NCI System Performance (#25-142-01) and Air Balancer (#25-143-01) certifications from the National Comfort Institute, plus EPA refrigerant certification (#P165BDDE28EAD0701). That training is why Novus catches the airflow and pressure faults a part-swapper misses. Novus Mechanical has served Freehold and Monmouth County homeowners since 2016, holds a 5.0 average across 48 Google reviews, and is fully insured. You get the full diagnostic and repair price in writing before any work begins.
Freehold is really three housing markets, and each one fails a different way. First, the 1960s Levitt-era split-levels in Stonehurst and Monmouth Heights, off Route 9 in West Freehold, fight uneven cooling from one undersized system feeding multiple half-levels. Second, the 1980s and 1990s colonials across Freehold Township run a hot second floor, an airflow and zoning problem rather than a dead compressor. Third, newer subdivisions like Freehold Pointe and the Regency at Freehold 55+ community run systems installed around 2004 to 2010, now hitting repair-or-replace age. Many homes carry basement air handlers in EPA Radon Zone 1, where sealing can cut bills by about 15%, according to ENERGY STAR. We measure every system the same way using MeasureQuick, wherever in Freehold or Monmouth County the call comes from.
