Common questions about heat pump installation costs, timelines, and what to expect.
Heat pump installation in Londonderry typically costs $5,000 to $12,000 for a standard split system including the outdoor condenser, indoor air handler or coil, new thermostat, refrigerant lineset, and all labor. High-efficiency variable-speed systems from Carrier, Trane, or Daikin with SEER2 ratings of 18 to 22 range from $10,000 to $18,000 installed. Ductless mini-split systems run $3,000 to $8,000 depending on the number of indoor zones. The total price depends on home size, system tonnage, efficiency tier, ductwork condition, and whether electrical upgrades are needed. KIC Refrigeration provides detailed proposals for Londonderry homeowners with all costs itemized and no hidden fees.
Many Londonderry homeowners qualify for substantial rebates and tax credits on heat pump installation. The federal energy-efficient home improvement credit covers up to $2,000 per year for qualifying heat pumps with SEER2 ratings above 16. State and utility rebates in NH may add $500 to $3,000 depending on the program and efficiency level. The Inflation Reduction Act provides additional point-of-sale rebates of up to $8,000 for qualifying heat pumps for income-eligible households.

A standard heat pump replacement in Londonderry where the existing ductwork and electrical service are adequate takes 1 full day — typically 6 to 10 hours from start to commissioning. New installations that require ductwork modifications, electrical panel upgrades, new concrete pads, or multiple zone setups may take 2 to 3 days. Mini-split installations with 2 to 4 indoor heads typically take 1 to 2 days. KIC Refrigeration provides a detailed timeline in your proposal, schedules the installation at a time that works for you, and keeps you informed on progress throughout the project at your Londonderry property.
A properly installed and maintained heat pump in Londonderry typically lasts 12 to 18 years before requiring replacement. Variable-speed systems with inverter compressors often last on the higher end of that range because they run at lower speeds most of the time, reducing mechanical stress and component wear. The single biggest factor in heat pump longevity is proper installation — correct refrigerant charge, proper airflow, and tight electrical connections — followed by annual professional maintenance. KIC Refrigeration offers annual maintenance plans for Londonderry customers that include coil cleaning, refrigerant pressure verification, electrical connection tightening, and capacitor testing to maximize your equipment lifespan.
