Central AC Installation in Lexington, MA
Lexington’s 1950s-1980s single-family homes on larger lots are prime candidates for full equipment replacement. Lexington is one of our most active Mass Save Heat Pump conversion markets. For AC installation specifically, the typical Lexington call comes in two flavors: an aging central system (15+ years old, R-22 refrigerant, declining efficiency) needing full replacement, or a homeowner adding cooling for the first time to a home that was originally heat-only. We handle both — including duct modifications, refrigerant lineset routing, electrical upgrades, and condensate management.
AC System Types We Install
Central air conditioning (split systems): Outdoor condenser plus indoor air handler or evaporator coil sharing the existing furnace blower and ductwork. Rheem Prestige and Classic series, two-stage and modulating units, 16-20+ SEER. Best for homes with existing forced-air heating.
Heat pump systems: Same equipment that cools also heats — at lower operating cost than gas/oil/propane in most temperature ranges. Mass Save rebates of up to $10,000 for whole-home conversions plus 0% HEAT Loan financing make these especially attractive in Lexington.
High-velocity small-duct systems: For older Lexington homes that don’t have ductwork and can’t accommodate traditional ducts. SpacePak and Unico systems use small flexible ducts that fit in existing wall cavities.
Ductless mini-split AC: When central AC is impractical (older homes without ducts, condo conversions, additions). Mitsubishi and Fujitsu single-zone and multi-zone systems. We handle these on our dedicated ductless mini-split installation in Lexington page.
What’s Included in AC Installation
Heat-load and Manual J calculation to size the system. Pulling the old equipment if replacing. Installing new outdoor condenser on a level pad with proper clearance. Running new refrigerant lineset and condensate drain. Installing new evaporator coil at the furnace. Updating electrical service and breaker if needed. Charging and commissioning the system. Pulling all required permits.
Mass Save Rebates and Financing

Frequently Asked Questions about AC Installation in Lexington
How long does AC installation in Lexington take?
A standard central AC replacement is typically 1 day. Adding central AC to a heat-only home takes 2-3 days for ductwork modifications, lineset routing, and electrical upgrades. We will give you an exact timeline at the in-home estimate.
Should I install a heat pump instead of standard AC?
Often yes. Heat pumps cool just as well as AC and also provide heating, eliminating most of your fossil-fuel heating bill. Mass Save rebates of up to $10,000 plus 0% HEAT Loan financing make the conversion math compelling.
Can my Lexington home support central AC if I have steam heat?
Yes — but it requires running new ductwork or installing a high-velocity small-duct system since steam-heat homes don’t have AC-compatible ducts. Ductless mini-splits are also a strong option. We will walk through tradeoffs at the estimate.
What SEER rating should I get?
For Lexington, 16-18 SEER offers the best return on investment. Going higher (20+) costs more upfront and saves more on operating costs but the payback period is longer. We will model both options at the estimate.

What we see in Lexington: Lexington housing tells you what to plan for before the truck rolls. Antique colonials around the Battle Green often hide knob-and-tube electrical adjacent to plumbing chases, requiring careful planning before any wall opens. Lexington Greens mid-century ranches typically have copper supply that's stood up well, but original water mains often need pressure regulation upgrades during fixture work. Construction along Route 2A is modern and code-current. From our Winchester shop it's about 12 miles to Lexington Center - 18-25 minutes typical drive.Other Services in Lexington
