For a full system replacement in Lexington, including a new outdoor condenser and indoor coil, homeowners can expect to pay between $6,500 and $12,000. The final cost depends on your home's size, the system's efficiency (SEER rating), and the complexity of the installation, which can be higher in our area due to older homes with unique layouts. It's wise to get 3 detailed estimates from licensed local contractors, as Massachusetts state and local utility rebates for high-efficiency units can significantly offset the initial investment.
The optimal times are during the shoulder seasons—late spring (April-May) for AC servicing and early fall (September-October) for furnace tune-ups. Scheduling during these periods ensures your system is ready for Lexington's hot, humid summers and cold, snowy winters, and you'll avoid the high-demand rush that leads to longer wait times. For replacements, planning an installation in the fall or spring often provides more scheduling flexibility and potential off-season discounts from local providers.
Yes, most HVAC installations, especially those involving fuel-burning equipment or major electrical work, require a permit from the Lexington Inspectional Services Department. A licensed Massachusetts Refrigeration Technician and a licensed electrician or plumber (for gas lines) must perform the work. Crucially, Lexington is part of the Mass Save® program, which often requires specific documentation and a participating contractor to qualify for valuable rebates and 0% financing on eligible upgrades.
Always verify that the contractor holds a valid Massachusetts State Refrigeration Technician license and proper insurance. Look for established local companies with strong reviews on community-focused platforms and ask for references from homes of similar age and style in Lexington. A reputable provider should offer a detailed, written estimate, clearly explain the recommended equipment for our climate, and be an authorized partner in the Mass Save® program to help you access incentives.
While a new, high-efficiency heating system will improve performance, it may not fully resolve comfort problems common in Lexington's historic homes. First, invest in a home energy assessment through Mass Save®, which includes air sealing and insulation recommendations. Addressing drafts and inadequate attic or wall insulation is often the most cost-effective way to improve comfort, reduce energy bills, and ensure your new HVAC system operates at its designed efficiency in our harsh New England winters.
