Four months of heavy work, then long stretches of none
Your air conditioner in New Brunswick works hard from June through September, then sits idle the rest of the year. Summer afternoons average 85°F, so the compressor runs long hours to keep up. That kind of steady demand after months of sitting is when weak capacitors and low refrigerant show up, usually as a system that runs but can't cool the house down.
Middlesex County has also seen 139 damaging wind events and 29 hail events over the past ten years, with hail up to 1.75 inches. Wind can knock debris into the outdoor unit's fins and fan, and hail that size can dent the cabinet or bend the coil fins enough to cut down airflow. If your unit sits outside and airflow through it is blocked, it will struggle to cool even on a mild afternoon.

A new air conditioner would save little on running costs in Middlesex County, so the repair decision comes down to the unit's condition.
Estimates for a typical Middlesex County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, New Jersey fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
New Jersey requires HVAC contractors to hold a state license.
The license is issued to the contractor, not the job, so the same license covers this repair and any other HVAC work that contractor takes on. New Jersey handles this at the state level only. Middlesex County and its towns cannot add their own licensing requirement on top of it, so the state board's record is the one that applies here no matter which town you're in.
For an air conditioner repair, the state license isn't the only credential in play. If the repair involves the refrigerant side of your system, the technician doing that part of the work must hold EPA Section 608 certification, a federal requirement that applies in every state on top of whatever New Jersey requires. That's separate from the HVACR license and it's the piece that specifically governs anyone handling refrigerant.

- Why is my AC not blowing cold air?
- Most often the filter is clogged and starving the system of airflow, so check that first. A dirty filter makes the coil so cold it freezes over, and once that happens the air coming out turns warm instead of cold. Low refrigerant from a leak causes the same thing, but only a licensed technician can check refrigerant, since opening that side of the system legally requires EPA certification. If the outdoor unit isn't running at all while the indoor blower is, that points to the compressor or the capacitor, and that's a repair, not something to test yourself.
- Why is my AC leaking water?
- Water around your indoor unit usually means the condensate drain line is clogged. Your AC pulls a lot of moisture out of the air all summer, and that water is supposed to run out through a drain line to the outside. Algae and dirt build up in that line over time and block it, so the water backs up and drips out wherever it can, often right at the unit. A clogged filter can cause this too, since it lets the coil ice over, and the water shows up when that ice melts faster than the drain can handle.
- Why won't my AC turn on?
- Start with your thermostat. Check that it's set to cool and below the room temperature, and if it runs on batteries, try fresh ones. If the thermostat looks right, check your breaker panel, since a tripped breaker will shut the whole system down with no warning at all. When neither of those is the problem, it's likely something electrical inside the unit itself, like a bad capacitor or a failed contactor, and that calls for a licensed technician to open it up and find the actual fault.
