Frequently Asked Questions About HVAC in Hanover

Get answers to common questions about hvac services in Hanover, New Hampshire.

1What is the best time of year to schedule a furnace tune-up or replacement in Hanover?

The ideal time is during the late summer or early fall, specifically August through October. This ensures your system is fully serviced before the intense Upper Valley winter hits, and you avoid the high-demand rush when temperatures first drop. Scheduling proactively also gives you and your contractor more flexibility for appointment times and any necessary parts ordering.

2How does Hanover's climate affect my choice between a standard and a high-efficiency heat pump?

Hanover's cold winters, where temperatures regularly drop below freezing, make the choice of heat pump critical. For effective year-round heating and cooling, you need a cold-climate (or "hyper-heat") model specifically designed to operate efficiently in sub-zero temperatures. A standard heat pump may struggle and require a backup heating system, making a cold-climate model a more reliable and efficient primary heat source for our region.

3Are there local rebates or incentives in New Hampshire for upgrading to a high-efficiency HVAC system?

Yes, homeowners should first check with Liberty Utilities or New Hampshire Electric Co-op, as they often offer rebates for installing high-efficiency heat pumps, furnaces, or boilers. Additionally, the state of New Hampshire may have its own incentive programs, and you should always inquire with your HVAC contractor, as they are typically up-to-date on the latest available local and federal tax credits for energy-efficient upgrades.

4What should I look for when choosing an HVAC contractor in the Hanover area?

Prioritize local, licensed, and insured contractors with extensive experience in New Hampshire's climate. They should be familiar with the specific challenges of older homes common in Hanover, such as insulation and ductwork issues. Check for strong references, membership in local business associations, and their ability to service the specific high-efficiency or cold-climate systems recommended for our region.

5My home uses oil heat. Is it worth switching to a different system given Hanover's energy costs and climate?

Given the volatility of oil prices and Hanover's long heating season, switching to a high-efficiency cold-climate heat pump system is often a cost-effective and environmentally friendly decision for primary heating, potentially using your existing oil system as a backup for extreme cold snaps. A professional energy audit and cost analysis from a local HVAC provider can compare projected annual costs of oil, propane, and modern electric systems specific to your home's efficiency.
