Frequently Asked Questions
How much does a new HVAC system cost in New Hampshire?
In 2025, a full HVAC installation (heating and cooling) for a 2,000 sq. ft. home typically ranges from $8,000 to $15,000. High-efficiency heat pump systems or complex ductwork replacements can push costs toward $20,000.
Do heat pumps work effectively in New Hampshire's winters?
Yes, modern cold-climate air-source heat pumps (ccASHPs) are designed to provide heat at temperatures as low as -15°F. Many NH homeowners use them as a primary heat source, often paired with a backup propane or oil system for extreme 'polar vortex' events.
Are there tax credits available for NH residents?
Yes, under the Federal Inflation Reduction Act (Section 25C), New Hampshire homeowners can claim a tax credit of 30% of the project cost, up to $2,000 annually, for qualifying heat pumps.
Does my HVAC contractor need a license?
General HVAC work doesn't require a state-level HVAC license, but the technician MUST have a Fuel Gas Fitters license for gas systems and an EPA Section 608 certification for handling refrigerants.
