In New Hampshire, your heating system isn't a luxury — it's a survival necessity. With average January lows around 11°F in Manchester and considerably colder in northern NH, a heating system failure during a cold snap can make your home unlivable within hours. Plumbing HVAC Services New Hampshire provides the full range of heating services to keep NH homes and businesses warm through the state's demanding winters.
Heating Services We Provide in NH
Heating Systems We Service in New Hampshire
Gas & Propane Furnaces
Forced-air furnaces are the most common heating system in New Hampshire, providing fast, effective heat distributed through ductwork. Modern high-efficiency condensing furnaces (96–98% AFUE) can cut heating bills by 20–30% compared to older 80% AFUE models. Common furnace issues we repair include failed ignitors, faulty flame sensors, heat exchanger cracks, inducer motor failures, and limit switch faults.
Boilers & Hydronic Systems
Boiler-based heating is popular in older New Hampshire homes and for homeowners who prefer the even, radiant warmth of hydronic systems. Hot water baseboard, steam radiators, and in-floor radiant systems all operate from a central boiler. We repair and service gas, oil, and propane boilers and maintain all associated hydronic components including pumps, expansion tanks, zone valves, and air separators.
Cold-Climate Heat Pumps
Modern cold-climate heat pumps — designed specifically for New England winters — have transformed heating options for NH homeowners. Systems from Mitsubishi, Bosch, Daikin, and other manufacturers maintain full heating capacity at temperatures down to -15°F or lower. When paired with a conventional backup (or as standalone in a well-insulated home), they dramatically reduce heating costs compared to propane, oil, or electric resistance heating.
Emergency No-Heat Service in New Hampshire
A heating failure in a New Hampshire winter is a genuine emergency. We maintain 24/7 emergency dispatch and prioritize no-heat calls during cold weather — aiming for arrival within 60 minutes across most NH service areas. We don't charge extra for weekend or overnight emergency calls.

New Hampshire's heating season runs roughly October through April — 7 months during which your heating system may log 2,000+ operating hours. An annual tune-up in fall, before the heating season begins, is the most cost-effective maintenance investment you can make. Our tune-up covers:
- Heat exchanger inspection for cracks (critical safety check for gas furnaces)
- Burner cleaning and combustion analysis
- Ignitor, flame sensor, and control board testing
- Blower motor inspection and lubrication
- Filter replacement
- Thermostat calibration
- Flue and venting inspection
- Safety control testing
- Carbon monoxide test
Heating System FAQs
Minor repairs like ignitor or flame sensor replacement typically run $150–$350. Motor replacements are $300–$600. Heat exchanger replacement or major control board repairs may cost $600–$1,200+. At a certain repair cost threshold, we'll recommend replacement — and we'll tell you honestly which makes more economic sense.
For homes currently on propane or oil, a cold-climate heat pump (possibly with a gas/propane backup) typically offers the lowest operating cost and qualifies for the best incentives. For homes on natural gas with existing ductwork, a high-efficiency condensing furnace (96%+ AFUE) is hard to beat on a cost basis. We provide a detailed operating cost analysis for any system we recommend.
A cracked heat exchanger is a serious carbon monoxide risk. Warning signs include soot around the furnace, a yellow or flickering flame (should be steady blue), headaches or nausea in the home when the furnace runs, or CO detector alerts. Our tune-up includes a thorough heat exchanger inspection — don't skip it.
Cold-climate heat pumps from major manufacturers now operate efficiently at temperatures well below -15°F. They're not the under-powered systems of 20 years ago. Properly sized and installed, they're a viable primary heat source for most NH homes — and the economics have improved dramatically with available rebates and incentives.
Gas furnaces typically last 20–25 years; boilers 25–30+ years; heat pumps 15–20 years. If your system is near end of life, losing efficiency, or requiring frequent repairs, replacement is often the better long-term investment. We'll give you an honest assessment — not a sales pitch.
