Complete HVAC installation in Lexington 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 Lexington 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 MA winter and summer design temperatures. As a rough reference, a well-insulated 2,000-square-foot home in Lexington 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 Lexington home to avoid oversizing, which causes short cycling, high humidity, and premature compressor wear.
A standard furnace and AC replacement in Lexington takes 1 to 2 days when existing ductwork, gas piping, and electrical service are adequate and the new equipment fits in the same location. A complete system replacement that includes ductwork modifications, new trunk lines, equipment relocation from basement to attic or vice versa, electrical panel upgrades, or zoning system installation may take 3 to 5 days. Multi-zone mini-split installations with 3 to 5 indoor heads typically take 2 to 3 days. KIC Refrigeration provides a clear timeline in every proposal, coordinates scheduling around your Lexington home availability, and keeps you informed on progress every step of the way.
Yes. KIC Refrigeration pulls all required mechanical, electrical, and gas permits for every HVAC installation in Lexington, MA. We prepare the permit application with equipment specifications and installation plans, pay the permit fee, schedule the inspection with the local building department, meet the inspector on-site, and ensure the installation passes all applicable mechanical code requirements. A building permit is not optional — it is required by law in most Lexington jurisdictions, and an unpermitted installation can void the manufacturer equipment warranty, create title problems when selling the home, and may not be covered by homeowner insurance if an HVAC failure causes property damage. KIC Refrigeration includes permitting in every installation project.
Our reputation is built on certified technicians, honest pricing, and results that last.
