New Hampshire labor rates are above the national baseline used for these estimates, mainly on labor and permitting. Parts are priced nationally, so the spread between quotes usually comes from labor, brand and whether a repair or a replacement is recommended — ask for both numbers when a component is more than ten years old.
Photograph the pump, filter, heater and controller labels (model and serial). It saves a diagnostic visit and lets the tech bring the right parts.

A compressed season: late-May openings, faithful summer weeks, and an early-October close ahead of the first freeze. Winter is about cover integrity under snow; spring is about how good the close was. Freeze damage — cracked pump housings, split filter tanks and burst above-ground plumbing — is the classic spring repair here, and a documented winterization is the best defense.
The largest listed markets are Nashua (21 companies), Manchester (14 companies).
Repair a component under about eight years old with a single failed part. Replace when the unit is older than ten years, when the repair is more than half the cost of a new one, or when a more efficient model — a variable-speed pump or a heat pump — pays back through lower New Hampshire energy bills within a few seasons. Ask for both quotes and the expected life of the new unit.

Repair when the pump is under about eight years old and one part failed — a shaft seal, capacitor or lid o-ring is a $325-class fix. Replace when the motor is more than ten years old, the repair is more than half the cost of a new unit, or you are still running a single-speed pump: a variable-speed model typically cuts pump electricity by 50–80% and is required for most new installs under federal efficiency rules.
The most common causes are low water flow (dirty filter, closed valve or a failed pressure switch), a failed igniter or thermistor, a tripped high-limit switch, gas supply problems or a control board fault. Check filter pressure and valves first; if flow is fine, a heater technician can test the switches and board in one visit. Repairs typically run $150–$550, and units past 12–15 years are usually replacement candidates at $2,700–$7,000.
Pump motors typically last 8–12 years, filter cartridges 2–4 years, DE grids 5–10 years and filter tanks 15–25 years. Gas heaters last 10–15 years and heat pumps 10–20 with clean water and steady flow. Salt cells run 3–7 years depending on runtime and calcium scaling. Balanced water and clean filters are the cheapest way to reach the long end of those ranges.
The outdoor season in New Hampshire runs mid-June through early September — about 3 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. Mid-June through early September unheated; heaters realistically buy a month more. Winters are long and hard-freezing, so full winterization with a snow-rated cover is the standard of care.

New Hampshire has no general statewide contractor license, so vetting is on you — insurance certificates, references, and recent local addresses matter more here. Pool permits and residential-code barrier requirements (fencing, self-latching gates) run through your town's building department.
Often, yes. Most manufacturers give a longer warranty — commonly three years instead of one — when equipment is bought and installed through a qualified pool professional, and some void coverage for online purchases installed by the owner. Ask the repair company whether it is a warranty station for your brand and keep the installation invoice with the serial number.
