Berlin doesn't ask much of an air conditioner
Summer afternoons here average 73°F, and most homes don't run cooling on a regular basis. An air conditioner that sits idle most of the year still needs to work when a hot stretch hits or a piece of equipment struggles to start after months off.
The bigger risk to the unit outside is the weather itself. The area has seen 62 damaging wind events and 25 hail events over the past ten years, with hail up to 2 inches. Wind can bend the fins on the outdoor coil or throw debris into the cabinet, and hail that size can dent the coil or the fan housing. If your AC is blowing warm air or won't start after a storm, that outdoor unit is the first place to look.

A new air conditioner would save little on running costs in Coos County, so the repair decision comes down to the unit's condition.
Estimates for a typical Coos 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.
New Hampshire leaves HVAC contractors off the state books entirely. There is no license and no registration, so no state agency tests them or keeps a record of who is doing this work in Coos County. Whatever protection you have comes from somewhere other than a state license, because in this state there isn't one.
For an air conditioner repair, that protection is federal. Any technician who opens the refrigerant side of your system, anywhere in the country, is required to hold EPA Section 608 certification. That rule doesn't come from New Hampshire and it isn't a license, but it's the one credential that applies here regardless of what the state does or doesn't require.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil, which can make the coil freeze up and push out warm or weak air. Low refrigerant from a leak causes the same thing, and that's not a top off job, since it means a leak somewhere in the system needs to be found and sealed. A failing capacitor or a stuck contactor can also keep the compressor from running even though the fan still blows. Only a technician with EPA Section 608 certification can legally open the refrigerant side to check the charge or repair a leak, so that part of the diagnosis has to go through a licensed contractor.
- Why is my AC leaking water?
- Water around your indoor unit almost always means the condensate drain line is clogged, and the pan is overflowing instead of draining outside like it should. Algae and dust build up inside that line over time and eventually block it. A frozen evaporator coil will also cause a puddle, but only after it thaws, since the meltwater has nowhere to go but down. If the coil was frozen, something is restricting airflow or refrigerant flow, and that needs a look before you turn the system back on.
- Why won't my AC turn on?
- Start with the simple things. Check that the thermostat is set to cool and below room temperature, and check that the breaker for the outdoor unit hasn't tripped. If those are fine, the problem is likely electrical, a bad capacitor, a failed contactor, or a tripped safety switch on the unit itself. New Hampshire doesn't license HVAC contractors, so ask about a contractor's experience and insurance directly rather than checking a state license number. Any repair that involves opening the refrigerant lines still requires EPA Section 608 certification no matter what state you're in.
