It takes about a minute.
Three months of real heat, then it stops
Summer here runs June through August, and afternoons average 82°F. That is a short season, but it is the three months a new air conditioner has to get right, cycling on through the warmest part of the day without a break.
Warren County has also logged 167 damaging wind events and 7 hail storms over the past ten years, one dropping hail over an inch wide. Outdoor units sit exposed to that. Any new install built since 2023 has to meet 13.4 SEER2, the federal efficiency minimum, so whatever goes in will start from that baseline.

New Jersey requires HVAC contractors to hold a state license.
The state board tests contractors before they can hold this license, and the license is what New Jersey has on file when work goes wrong. It belongs to the contractor, not to any single job, so it follows them from one house to the next. Warren County has no separate license on top of it, because New Jersey does not let towns add their own.
On this job, the license tells you the contractor who shows up is the one the state tested and tracks. In most cities and counties, an installation like this still needs a permit from the local building office and an inspection once the work is done, and that is where the connections get checked here, separate from the license itself.

- What size air conditioner does my house need?
- The right size depends on your square footage, your insulation, how many windows you have and which way they face, your ceiling height, and how many people live there. A unit that is too big cools the room fast but shuts off before it pulls the humidity out, so the air stays damp. A unit that is too small runs constantly and never quite catches up on the hottest afternoons. A contractor works this out with a load calculation done room by room, not just a chart based on square footage.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed together and matched to each other, replacing only the outdoor unit can leave you with a mismatched system that never runs at its rated efficiency. Age matters too. If the indoor coil is old, it may fail soon after, and you end up paying for two jobs instead of one. A contractor can check whether your existing coil and ductwork will work with a new outdoor unit or whether the whole system needs to come out together.
- Do HVAC contractors in Phillipsburg need a state license to work on my home?
- Yes. New Jersey requires HVAC contractors to hold a state license, issued through the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. The license belongs to the contractor, not to each job, and no city or town in New Jersey can require its own separate license on top of it. For an AC installation, you will also need a permit from your local building office, with an inspection once the work is finished.
