Your AC in Lebanon barely has to work
Summer afternoons here average 76°F, so the compressor isn't running hard or running often. That's easy duty for an air conditioner, and it shows in how long the parts last.
What wears on a system in this area is more likely to be weather than heat. Grafton County has seen 30 hail events and 133 damaging wind events over the past ten years. A tune-up checks the cabinet, the coil fins, and the wiring for storm damage that a mild summer won't reveal on its own.

New Hampshire has no state license for HVAC contractors.
There is no state record of who does this work in Grafton County. New Hampshire does not test HVAC contractors, does not register them, and leaves no license number to check. Nothing about a contractor's standing here comes from the state.
For a maintenance visit on an air conditioner, the protection that does exist is federal, not local. Any technician who opens the refrigerant side of the system, which a proper tune-up includes, has to hold EPA Section 608 certification. That is a requirement in every state, including this one, and it applies regardless of what New Hampshire does or does not license.

- What does AC maintenance include?
- A maintenance visit covers checking refrigerant charge, cleaning the condenser coil, checking electrical connections, and testing that the system cycles on and shuts off correctly. The contractor also checks the filter and airflow through the ducts, since a dirty filter makes the whole system work harder. Any work on the refrigerant side has to be done by a technician with EPA Section 608 certification, which is a federal requirement everywhere, not just here.
- How often does an air conditioner need maintenance?
- Most advice you will hear is once a year, timed before the cooling season starts. Lebanon summers run mild, with afternoons averaging 76°F, and homes here need cooling for none of the year on average. Given that, a contractor can tell you whether your system even gets enough use to need a yearly visit, or whether checking it every couple of years makes more sense for your house.
- Is AC maintenance worth it?
- It depends on how much your system actually runs. In a place like Lebanon, where summer afternoons average just 76°F and homes need cooling for none of the year, an air conditioner sees far less use than it would somewhere hot. That said, this area has seen 133 damaging wind events and 30 hail events over the past ten years, and storm damage to the outdoor unit is worth catching early. A contractor can look at your specific system and tell you what makes sense to check and how often.
