Furnace and air conditioner repair in Andover (40509)
Andover's brick two-stories sit over basements, and larger plans may split heating and cooling between two systems. When one falls behind, the whole house feels it, usually on the hottest or coldest night of the year.
Short answer: HVAC service in Andover
We repair gas furnaces, air conditioners and heat pumps in Andover (40509), the southeast Lexington neighborhoods off Todds Road and Man o' War Boulevard around the former Andover golf course. In Andover Hills, homes are mostly brick, built from the 1970s through 2011 and usually over basements, alongside 1990s brick townhomes with no basement at all.
Brick homes, golf townhomes and fairways turned into parkland
Andover takes in several neighborhoods in southeast Lexington. Andover Hills sits off Todds Road near Hays Boulevard, with Jacobson Park on its western side. It was developed by Lochmere Development Corporation, and homeowners took over the association in 1995. Andover Forest lies along Man o' War Boulevard beside the Brighton East Bike Path, which follows an old rail line.
In Andover Hills, single-family homes are mostly brick, built from the 1970s through 2011, about 2,000 to 7,000 square feet, and most have basements, many of them finished. Brick townhomes from the 1990s, roughly 1,100 to 2,000 square feet with garages, have no basements. Natural gas heat with electric central air is a common pairing in the larger homes.
The Andover Golf and Country Club opened around 1990 and closed in 2017. In 2018, six neighborhood associations bought the course from the bank, and most of it is now held by the associations as green space. For lots that back to it, that means open views, full sun on the back of the house and outdoor units that collect grass clippings and pollen in mowing season.

What wears down heating and cooling in Andover two-stories
Two floors over a basement, and sometimes two systems, bring their own weak points.
Upstairs systems working overtime
Where a separate system serves the second floor, it fights attic heat all summer, runs longer and often fails sooner than the main unit. A window unit in a bedroom is a sign it is falling behind.
Attic equipment and drain pans
Where an upstairs furnace or air handler sits in the attic, summer heat bakes wiring and capacitors, and a clogged drain pan can stain the bedroom ceiling below.
Original 1990s furnaces
Furnaces still running from the 1990s are now around 30 years old. Cracked heat exchangers, worn inducer motors and failed control boards are common at that age.
Finished basements running damp
A basement on the main system cools quickly but rarely runs long enough to dry the air. Carpeted lower levels can smell musty by August even with the thermostat set low.
Mismatched outdoor and indoor units
When an outdoor unit was replaced without its indoor coil, the mismatched pair loses capacity and efficiency and often struggles to pull humidity out of the house.
Townhome closets with little room
Townhomes without basements put the furnace or air handler in a closet, garage or attic, where tight clearances make service and replacement slower.
What replacing one system costs in an Andover home
In a two-system house, one side usually fails first. For a gas furnace and matching central air serving one floor, 2026 prices in Andover typically fall in this range.
- Attic or basement location. Attic installs take more time and handling than basement swaps, especially with narrow pull-down stairs.
- Furnace efficiency. A 95 percent furnace needs side-wall venting and a condensate drain, while an 80 percent unit can reuse a sound existing vent.
- Cooling capacity and stages. Two-stage or variable-speed central air costs more but handles humidity and upstairs heat noticeably better.
- Coil and line set. New A2L refrigerant systems need a matched indoor coil and often a new line set to the outdoor unit.
- Duct repairs. Crushed attic flex duct or a missing upstairs return adds labor when we find it during the job.
Ranges are typical, not a quote. You get a written price after we look at the system, the access and the ductwork. Compare typical prices for every service.

Keeping an Andover basement dry and the upstairs cool
Two-story homes over basements fight two climates at once. Through a humid Kentucky summer the basement stays cool and damp, while the upstairs soaks up attic heat. A single thermostat on the main floor satisfies itself and leaves both extremes alone, which is why the same house can feel clammy downstairs and stuffy upstairs on the same afternoon.
Our first step is usually airflow, not equipment. We measure static pressure, check that upstairs returns exist and are not blocked, and look at attic duct insulation. For the basement, a ducted whole-house dehumidifier or a dedicated zone can hold humidity near 50 percent without overcooling the room. In homes with one system serving everything, zoning the existing system can be a lower-cost alternative to adding a second unit.
What Andover homes call us for
Furnace Repair
Original 1990s gas furnaces in larger Andover homes are at the age when inducers, control boards and heat exchangers fail.
AC Repair
Upstairs cooling works hardest against attic heat, and a weak capacitor or dirty coil shows up first on hot afternoons.
HVAC System Replacement
Homes with two systems often replace one side at a time, and matching new equipment to the existing ducts matters more than tonnage.
Whole-House Dehumidifiers
Finished basements in Andover two-stories hold summer moisture that the main system does not run long enough to remove.
Furnace Tune-Ups
A fall check on both furnaces catches cracked igniters and dirty flame sensors before the first cold night.
AC Drain Line Repair
Attic air handlers above finished bedrooms need clear condensate lines and working float switches to keep ceilings dry.
Andover heating and cooling questions
Does the former Andover golf course affect the outdoor AC unit behind my house?
Only in small ways. Lots that back to the old course get more open sun and wind, and mowing season sends grass clippings and pollen toward outdoor units. Keep two feet of clearance, rinse the fins gently with low-pressure water each spring, and have the coil cleaned during an AC tune-up if the unit faces the open land.
What should I check first if my Andover townhome has no heat?
Make sure the thermostat is set to heat and has power, the furnace switch near the closet is on and the breaker has not tripped. Look at the filter, since a clogged one can trip the high-limit switch. If the furnace still will not start, or you smell gas, call us at (859) 377-8167 at any hour.
Why does the finished basement in my Andover home smell musty in August?
Basements stay cool, so the main system satisfies the thermostat before it removes much moisture down there. Humidity climbs above 60 percent, and carpet and drywall start to hold it. A ducted dehumidifier, a return in the basement and a properly sized system usually clear the odor within a few weeks of steady drying.
