From initial contact to final verification — here is how we handle hvac installation.
Our Nashua estimator walks your property room by room — measuring square footage, checking insulation levels, assessing window area, and inspecting existing ductwork and electrical service. We input all variables into a Manual J load calculation to determine your exact heating and cooling requirements in BTU.
Based on load calculations and your priorities — efficiency, noise level, budget, zoning — we recommend specific equipment and provide a detailed written proposal covering equipment model numbers, SEER2/AFUE ratings, installation scope, warranty, and total cost.
KIC Refrigeration installs HVAC systems in Nashua, NH to the highest standards. We set equipment on level, vibration-isolated mounting, braze all refrigerant connections with nitrogen flowing, pressure test with dry nitrogen, evacuate to below 500 microns, charge by weight, seal all duct connections with mastic, and verify gas piping sizing and connections.
Our Nashua technician commissions the system by verifying superheat, subcooling, temperature split, static pressure, and gas pressure in heating mode. We program the thermostat, register your manufacturer warranty, label the electrical panel, and walk you through operation and maintenance.

Complete HVAC installation in Nashua ranges from $7,000 to $15,000 for a mid-efficiency furnace and AC combination — typically an 80 percent AFUE furnace paired with a 14.3 to 16 SEER2 condenser. High-efficiency systems with variable-speed blowers and two-stage or variable-speed compressors run $12,000 to $22,000 but deliver significantly lower operating costs and qualify for federal tax credits. Heat pump systems fall between $5,000 and $18,000 depending on whether the system is single-stage, variable-speed, or a dual-fuel configuration. Ductwork modifications or new duct runs add $1,000 to $5,000. KIC Refrigeration provides detailed written proposals for Nashua homeowners with every cost itemized and no hidden fees.
Correct HVAC system sizing is determined by a Manual J residential load calculation — the ACCA industry standard — that accounts for your home square footage, ceiling height, insulation R-values, window area and U-factor, air infiltration rate, duct losses, occupancy, and the local NH winter and summer design temperatures. As a rough reference, a well-insulated 2,000-square-foot home in Nashua typically needs a 2.5 to 3.5 ton system, while a poorly insulated home of the same size may need 4 tons. KIC Refrigeration never estimates by rule of thumb — we run a proper calculation for your specific Nashua home to avoid oversizing, which causes short cycling, high humidity, and premature compressor wear.
Yes, substantially. Replacing a 10 SEER air conditioner with a 16 SEER2 unit reduces cooling energy consumption by approximately 38 percent. Upgrading from an 80 AFUE furnace to a 96 AFUE condensing furnace saves 16 cents of every heating dollar — the old furnace sends 20 cents up the flue while the new one captures it. Combined with proper installation practices — correct refrigerant charge verified by superheat and subcooling, proper static pressure and airflow at 400 CFM per ton, sealed duct connections, and a programmable thermostat — a new system typically saves Nashua homeowners $600 to $1,800 per year depending on home size, usage patterns, and local energy rates.
The best HVAC brand depends on your budget, efficiency goals, warranty requirements, and desired features. Carrier, Trane, and Lennox are premium tier brands with extensive 10-year parts warranties and the widest selection of variable-speed equipment. Goodman, Rheem, and Ruud offer excellent value with solid warranties at a lower price point — often $2,000 to $4,000 less than premium brands for equivalent tonnage. Daikin and Mitsubishi lead the market in ductless mini-split and inverter heat pump technology. All major brands manufacture reliable equipment — proper installation quality matters more than the brand name on the box. KIC Refrigeration installs all major brands and recommends the best match for your Nashua home and budget.
