Four months of hard running, every year
Trenton only asks for cooling June through September, but those four months work the system hard. Summer afternoons average 85 degrees, and the air conditioner runs long hours to hold the house steady against that heat. Parts wear from that kind of steady demand, especially the ones nobody looks at until they fail.
A tune-up before the season starts checks the refrigerant charge, the electrical connections, and the condenser coil, so a small problem gets caught while it is still small. Mercer County has also seen 23 hail events and 112 damaging wind events over the past ten years, and a technician can spot hail dents or bent fins on the outdoor unit before they turn into a bigger repair.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
New Jersey requires HVAC contractors to hold a state license.
New Jersey licenses HVAC contractors through the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. That license means the state tested the contractor and keeps a record of them. It covers the contractor, not each individual job. Because the license sits at the state level, no town in Mercer County can require its own license on top of it.
For maintenance on an air conditioner, the state license is what stands behind the contractor who takes the job. If the work involves opening the refrigerant side of the system, whoever does that also needs EPA Section 608 certification, a federal requirement that applies to that kind of work in every state.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil outside, and checks the electrical connections and capacitor. They also check the filter, look at the blower, and check the condensate drain to make sure it isn't clogged. Coils that stay clean and connections that stay tight are what let the system cool the house without straining. Anyone opening the refrigerant side of the system has to hold EPA Section 608 certification, and in New Jersey the contractor also has to hold a state HVAC license.
- How often does an air conditioner need maintenance?
- Once a year, before the cooling season starts, is standard. Here that means getting it done before June, since the system runs from June through September and summer afternoons average 85°F. A yearly check catches a weak capacitor or a dirty coil before the system has to work through a stretch of hot afternoons.
- Is AC maintenance worth it?
- Yes, because a system that only runs part of the year needs to be ready when that stretch starts. Homes here only need cooling for about 4 months, June through September, so there isn't much room to lose a week of it to a problem that a check would have caught. Maintenance also gives a technician a chance to spot corrosion or loose wiring from wind or hail, and this area has recorded 112 damaging wind events and 23 hail events over the past ten years.
