Two months of real work, then ten months of standing still
Your air conditioner earns its keep in July and August here, when afternoons average 80°F, then sits idle the rest of the year. That kind of schedule is hard on it in its own way. A system that runs hard for two months and then shuts down for ten has time for dust to settle on the coil and moisture to sit in parts that were just working.
Rockingham County has seen 103 damaging wind events and 29 hail storms over the past ten years, with hail up to 1.75 inches. The outdoor unit sits outside through all of it. A tune-up checks the coil fins for damage, the fan blade for wear, and the electrical connections for corrosion before the next hot stretch asks the system to work.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
New Hampshire has no state license for HVAC contractors.
New Hampshire does not license HVAC contractors. It does not register them either. There is no state board testing this trade and no state list to check a contractor against.
For a maintenance visit on an air conditioner, the protection that does exist comes from federal law, not the state. Any technician who opens the refrigerant side of the system, to check the charge or recover refrigerant, has to hold EPA Section 608 certification. That rule holds in every state, including this one.

- What does AC maintenance include?
- A technician checks refrigerant pressure, cleans the condenser coil, and tests the capacitor and contactor. They also check the electrical connections and flush the condensate drain so it isn't clogged when you need the system most. Only someone with EPA Section 608 certification can legally open the refrigerant side of the system, so that part of the check has to come from a certified tech. New Hampshire doesn't license HVAC contractors, so ask about that certification directly before the work starts.
- How often does an air conditioner need maintenance?
- Once a year, before the season it has to work hardest. In Portsmouth that means getting it looked at before July and August, the two months homes here actually need cooling. Summer afternoons average 80°F, which isn't extreme heat, but a unit that sat idle most of the year still needs its coil and connections checked before it starts running every day.
- Is AC maintenance worth it?
- Yes, because most breakdowns start as small problems that a checkup catches before the unit quits on a hot day. A dirty coil or a weak capacitor won't stop your AC right away, but they make it work harder and wear out sooner. Portsmouth has seen 103 damaging wind events and 29 hail events over the past ten years, and a yearly check is when a technician would notice a bent fin or a dented cabinet before it turns into a bigger repair.
