Two months of real work, then months of nothing
Your air conditioner in Manchester only earns its keep in July and August, with afternoons averaging 79°F. That short, hard stretch is what wears it out. A unit that sits idle most of the year can struggle the first hot day it is asked to run for hours straight, and a capacitor or contactor that was already weak often fails right then.
Hillsborough County has also logged 147 damaging wind events and 30 hail events over the past ten years, with hail up to 1.75 inches. Wind can knock the outdoor unit's fan out of balance or bend the cabinet enough to rub the fan blade. Hail that size can dent the condenser coil's thin fins, and once they're crushed the coil can't shed heat the way it should. You'll notice it as an air conditioner that runs but doesn't cool the house like it used to.

A new air conditioner would save little on running costs in Hillsborough County, so the repair decision comes down to the unit's condition.
Estimates for a typical Hillsborough County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, New Hampshire 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 Hampshire has no state license for HVAC contractors.
There is no state registry to check, no exam record, and no license number tied to the business doing your repair. Whatever confidence you have in a contractor here comes from the contractor's own record and reputation, not from a state file that says they were tested.
What does apply, no matter what state you're in, is federal. Your air conditioner's repair almost certainly means opening the refrigerant side of the system to check the charge or fix a leak, and anyone who does that has to hold EPA Section 608 certification. That's not a New Hampshire rule and it's not optional, it's a federal requirement tied to the individual technician, and it exists because refrigerant itself is regulated, not because the state is watching the job.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow, so check that first since it's the easiest to fix. If the filter is clean, the problem could be low refrigerant from a leak, a failing compressor, or a coil that's frozen over. A frozen coil often points back to restricted airflow too, whether from the filter or from blocked vents. A contractor can check the refrigerant charge and find where a leak is coming from, since that side of the system legally requires EPA 608 certification to open.
- Why is my AC leaking water?
- Most of the time this means the condensate drain line is clogged and water is backing up instead of draining outside. Algae and dust build up in that line over a cooling season and block it. It can also happen if the coil has frozen and then thawed, sending more water to the drain pan than it can handle at once. A contractor can clear the line and check whether something upstream, like airflow across the coil, caused the freeze in the first place.
- Why won't my AC turn on?
- Start with the thermostat, since dead batteries or a setting knocked into the wrong mode will stop the system before it ever starts. If the thermostat looks fine, check the breaker, since AC units trip breakers more than people expect. Beyond that it could be a bad capacitor, a tripped safety switch, or a wiring issue, and those need a contractor to diagnose. New Hampshire doesn't license HVAC contractors, so ask about their experience and insurance directly when you call one.
