HVAC Company in Lexington, MA
Lexington’s HVAC work runs through a specific set of conditions: 1950s and 1960s housing stock built for oil-fired baseboard heat, no ductwork in most homes, and winter design temperatures that sit colder than Boston’s coastal suburbs. That combination shapes nearly every repair and installation we do here. We’re Meadowsweet Heating & Air, an independently operated location within the Cedarwell family of companies, and our Lexington jobs are led by Luis Serrano. All three services on this page have their own dedicated Lexington pages, linked just below. Call (747) 966-3037 any time; a live person answers.
Why Lexington Homes Are Different
The houses tell the story. Lexington’s Route 128 boom produced thousands of ranches, split-levels, and center-entrance Colonials, nearly all of them heated by oil-fired boilers feeding hot-water baseboard. Most have no central air ducts at all. When a furnace repair call comes in, it’s usually a boiler, not a forced-air furnace. When an AC installation is on the table, ductless mini-splits or hybrid systems usually make more sense than trying to retrofit ducts through finished basements and closets.
Lexington’s distance from Boston Harbor matters more than people expect. Roughly 12 miles inland, the town doesn’t get the ocean’s moderating effect during cold snaps. Heating design temperatures here run slightly colder than Quincy or Winthrop, which means cold-climate heat pumps rated to -13°F or below are the practical choice, not a premium upsell. We also see a lot of work in the neighborhoods near Lexington Center and the Battle Green, where 18th- and 19th-century Colonials and Federals sit under historic district review. Exterior condenser and compressor placement on street-facing elevations can be restricted there, so equipment location gets decided carefully before any installation quote is written.
Our Main Lexington Services
These are the two calls we hear most often from Lexington households, plus the installation work that’s become the town’s dominant HVAC project. Each has its own Lexington page with pricing, timelines, and local specifics.
AC Repair in Lexington
Lexington’s AC calls cluster in two patterns. First, older central systems in the few homes that do have ductwork, often added in the 1980s and 1990s and now running on borrowed time. Second, ductless mini-split systems in converted oil-heat homes, where one indoor head failing while others run fine is the classic symptom. We know the split-level stratification problem on streets like those in the Peacock Farm area: warm air pools upstairs, the first floor stays cool, and someone has already turned the thermostat down too far trying to compensate. A repair that treats the actual cause beats a patch that holds two weeks. Luis Serrano and the crew write a clear price before any work begins, and the repair carries our 365-Day Done Right Promise. See AC Repair in Lexington for full details.

Furnace Repair in Lexington
Most Lexington “furnace” calls are actually boiler calls. Oil-fired hot-water systems from the 1960s and 1970s are the town’s default heating plant, and their failures are specific: circulator pumps wearing out, zone valves sticking, expansion tanks waterlogging. We also handle the gas furnaces in newer construction and the few homes converted from oil over the years. Lexington’s colder inland winter means a no-heat call is urgent in a way it isn’t in Boston’s harbor-facing towns. Same-day response is standard, and we answer the phone live at any hour, no voicemail queue. Every repair starts with a written price and ends with drop cloths picked up and floors left as we found them. Read the full scope at Furnace Repair in Lexington.

AC Installation in Lexington
This is where Lexington’s housing stock really drives the decisions. A home with hot-water baseboard and no ducts can’t accept a standard central AC system without major construction. The practical routes are ductless mini-splits, one per zone, or hybrid systems that pair heat pumps with the existing oil boiler for the coldest days. Sustainable Lexington’s push and the Net Zero Action Plan adopted by Town Meeting have made oil-to-heat-pump conversion the dominant project type here, and Mass Save rebates usually apply. Ductless heads also solve the split-level stratification issue directly by giving each level its own temperature zone. We size systems to the house, not a rule of thumb, and a written fixed price comes before any equipment is ordered. See AC Installation in Lexington for equipment options and local rebate guidance.

What pushes a Lexington job toward the higher end? Historic district constraints near Lexington Center that restrict condenser placement, older homes where running a new lineset is tight hatch-and-closet work, and split-levels that need two or three indoor heads rather than one. What doesn’t change is the price promise: it’s written down before we touch anything, and the clean-up photo is part of every job, not an extra.

FAQs About HVAC Company in Lexington
Same day, usually within 90 minutes. Lexington’s inland location makes cold snaps more severe than in Boston’s coastal suburbs, so we treat no-heat calls here as the urgent situations they are. The phone is answered live 24/7, including weekends and holidays. Call (747) 966-3037.
Yes, in some cases. Homes near Lexington Center and the Battle Green that fall under historic district review may face restrictions on exterior condenser and compressor placement on street-facing elevations. We check the applicable rules before quoting any installation, and we plan equipment location to meet both code and the review board’s requirements.
We do, and it’s now the most common project type we take on in Lexington. The standard approach pairs cold-climate heat pumps or ductless mini-splits with the existing oil boiler as backup, because Lexington’s baseboard loops need water temperatures higher than standard heat pumps deliver alone. Mass Save rebates often apply. Call (747) 966-3037 for an exact quote; estimates are free.

What Lexington Customers Say
"Good repair and a very tidy, respectful tech. The appointment window was wide and he came near the end of it, but he texted ahead. Work itself was clean and done right."
- Nadine Oakley"Furnace tune up before winter. He was careful going in and out, closed the gate behind him every time because of the kids, and cleaned up the work area completely. Calm, thorough guy."
- Marcus Pell"Comfortable in every room now, and not a trace that a crew had been here. Booties, drop cloths, the works. They even wiped down the thermostat they'd handled. Really considerate."
- Lamar Finch
