Get answers to common questions about hvac services in Northumberland, New Hampshire.
The ideal times are during the shoulder seasons of late spring (May-June) and early fall (September-October). This avoids the peak summer cooling and harsh winter heating demands of our North Country climate, ensuring better availability from local technicians and often more flexible scheduling. It also allows you to proactively prepare your system for the intense cold of a White Mountains winter or the occasional summer heat wave.
Given our long, cold winters with temperatures often well below freezing, system durability and efficiency at low temperatures are critical. For heat pumps, you must choose a cold-climate model specifically rated for New Hampshire winters to ensure reliable performance. Furnaces and boilers should be properly sized for the home's heat loss calculation, and investing in high-efficiency models (like 95%+ AFUE furnaces) can lead to significant savings on heating oil or propane, which are common fuels in our rural area.
While Northumberland itself may not have unique town codes, all installations must comply with New Hampshire state building and mechanical codes. Importantly, New Hampshire offers specific incentives, such as rebates through NHSaves for qualifying high-efficiency heat pumps, furnaces, and boilers. Additionally, any work on fuel-burning appliances must be permitted and performed by a licensed NH gas fitter or oil burner technician, which is a key credential to verify when choosing a provider.
Prioritize contractors who are licensed, insured, and have extensive experience with the specific fuel types and systems common to older homes in our region (e.g., oil boilers, propane furnaces). Look for established local companies with a physical presence in Coös County or the North Country, as they understand the challenges of rural service calls and our climate. Always check for references from nearby towns and verify their membership with the NH Plumbing and Mechanical Licensing Board.
Some icing on the outdoor unit is normal during operation in damp, cold weather, and the system should periodically go into a defrost cycle. However, excessive buildup or a complete loss of heat output during Northumberland's deep cold spells may indicate an issue with the defrost controls, refrigerant charge, or that the unit is not a true cold-climate model. Given our sub-zero temperatures, it's crucial to have a local professional service it and confirm it's appropriately sized and specified for our climate zone.
