At your Durham property, our technician performs a room-by-room heat load calculation accounting for square footage, insulation R-values, window area, orientation, and local design temperatures. The result determines the exact tonnage and HSPF rating your home requires.
KIC Refrigeration provides Durham, NH homeowners with detailed equipment proposals that include model specifications, AHRI-certified efficiency ratings, estimated annual operating costs, available rebates and tax credits, and a complete installation scope of work with no hidden costs.
Our crew installs the outdoor condenser, indoor air handler or coil, new refrigerant lineset, thermostat, and disconnect. We braze all connections with nitrogen purge, pull a deep vacuum, and charge the system by weight per the manufacturer specification.

Heat pump installation in Durham 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 Durham homeowners with all costs itemized and no hidden fees.
A properly installed and maintained heat pump in Durham 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 Durham customers that include coil cleaning, refrigerant pressure verification, electrical connection tightening, and capacitor testing to maximize your equipment lifespan.
A standard heat pump replacement in Durham 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 Durham property.
Yes. KIC Refrigeration handles all mechanical and electrical permits required for heat pump installation in Durham, NH. We prepare and submit the permit application, schedule the inspection with the local building department, and ensure the installation passes all applicable code requirements. A building permit is required by law for HVAC equipment replacement in most jurisdictions, and it protects you as the homeowner — an unpermitted installation can void the manufacturer warranty, create problems when selling the home, and may not be covered by homeowner insurance if a failure causes property damage. KIC Refrigeration includes permitting in every installation proposal.
