Three months of real heat is still three months of hard work
Morristown summers run June through August, with afternoons averaging 82°F. That is a short season, but a new air conditioner still has to keep up on the hottest days in it, and it has to sit outside through the rest of the year exposed to whatever comes.
Storms are part of that. Morris County has logged 188 damaging wind events and 31 hail events over the past ten years, with hail up to 1.5 inches. An outdoor unit needs to hold up to that, not just cool the house. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2, so whatever goes in will start from that baseline.

New Jersey requires HVAC contractors to hold a state license.
The license comes from the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors, and it covers the contractor rather than each job they take on. New Jersey does not let towns or counties set their own HVAC licensing on top of that, so this is the license that applies to the work, wherever in the state the home is.
For an air conditioner installation, that license is what stands behind the person doing the work. In most cities and counties, the job will also need a permit from the local building office, with an inspection once the installation is finished. That inspection checks the work itself, separate from the license the contractor already holds.

- 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, and your ceiling height. A contractor works this out with a load calculation, not a tape measure and a chart. Going bigger than what the calculation says is not a safety margin. An oversized unit cools the air fast and shuts off before it pulls the moisture out, so the house feels damp even at the right temperature. A properly sized system installed for your house is worth more than a bigger box installed for a house down the street.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both the outdoor unit and the indoor coil together, not just the outdoor unit. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old indoor coil usually gives up performance you paid for. There are also refrigerant differences between older and newer systems that can rule out mixing parts outright. A contractor can look at your existing coil and tell you whether it can stay or has to go.
- Do HVAC contractors in Morristown 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 the individual job, and no town in New Jersey can layer its own license requirement on top of that. You will still need a permit from Morristown's local building office for an air conditioner installation, along with an inspection once the work is done.
