HVAC maintenance in New Hampshire is a scheduled visit, not an emergency repair and not a cleaning sold under a vague name. Call (603) 420-0791, say whether you want the heating plant, the cooling system, or both, and give your ZIP code. An independent contractor quotes the tune-up after they know what equipment is in the house. Confirm license and insurance. This site does not sell service plans and does not promise that a tune-up prevents every breakdown.
A heating tune-up before the season should match the appliance. On a gas furnace that means burners, flame sensor, filter, blower, condensate, vent, and a combustion check the contractor is equipped to do. On an oil furnace or oil boiler it means the burner, nozzle, flue passages, and safety controls. On a heat pump it means coils, filters, defrost operation, and the backup heat strips or the dual-fuel furnace. On a boiler it means the aquastat, circulators or zone valves, relief valve, and the expansion tank. A single checklist pasted over all of those machines is not a tune-up. Say what you own when you call.
Cooling visit
A cooling tune-up in late spring covers the condenser coil, the indoor coil if it is reachable, the drain, the capacitor, the contactor, and the temperature split. It finds a weak capacitor before the first heat wave. It does not refill refrigerant as a courtesy. If the charge is low, that is a leak search and a repair quote.
How often
For a furnace, the practical rhythm in this climate is a visit before the heating season, with filters changed more often than that. The reasoning is in how often to service a furnace. Cooling equipment wants attention before summer, especially after a winter of sitting under pollen and road dust. Heat pumps that run all year deserve a look twice, because they never get a long idle season. None of those intervals is a statute. They are a way to talk to the contractor about scope.
Typical cost factors
The quote depends on how many appliances, the fuel, whether combustion testing is included, and travel to your town. This page does not print a tune-up price. We do not have a cited New Hampshire fee schedule. Ask what is included, what is extra if a part has failed, and whether the visit fee applies to a repair the same day. A maintenance visit that discovers a cracked exchanger or a failed compressor should stop and become a repair conversation. See when to repair or replace.
You choose the contractor's quote or you do not. The contractor is independent. People in photographs are actors or models, not listed contractors.
What to keep from the visit
Ask for the readings they took and the filter size in writing. A sticker on the cabinet with the date is more useful than a club card. If they recommend a repair, ask them to separate it from the tune-up price before they start. You should be able to pay for the visit, decline the repair, and call someone else. A contractor who treats that as an insult is telling you something about the visit.
Keep a simple log: date, filter, anything they said to watch. Over three years the log shows whether you are buying the same repair every fall. That pattern is the moment to read the repair-versus-replacement guide, not the moment to buy another maintenance plan you do not understand. This site does not sell those plans. If a contractor offers one, ask what is included, what is excluded, and what happens if they sell the company. The plan is their product, not ours.
Group appliances into one visit when they are in the same house: furnace and air conditioner in the spring or fall, boiler and indirect water heater together, heat pump twice a year if it runs all seasons. You will get a clearer quote than if you book three trips. Tell the contractor about any alarm, any leak, and any room that misbehaves so the tune-up is not only a checklist. A checklist that ignores the complaint you actually have is how maintenance visits feel useless. The visit can still be maintenance. The findings can still become a repair you approve separately. Those are two line items, and you should see both.
