Furnace Repair in Andover, CT
Andover sits in the eastern Connecticut uplands, where wooded hills and open ridgelines shape how hard a furnace has to work. Homes along Route 6 and the back roads off Hebron Road catch steady winter wind, and many of the older farmhouses and capes scattered around town were framed long before anyone thought much about air sealing.
Winter arrives early here and settles in. Once January hits, a furnace in Andover can run almost nonstop for weeks, and any small weakness in the system tends to surface at the worst possible moment.
SM Mechanical Services LLC is a family owned heating and plumbing company, and we answer calls in Andover around the clock. Our licensed technicians service all makes and models, so the age of your system or who installed it is never a problem.
Signs Your Furnace Needs a Repair Call
Furnaces almost never quit without warning first. These are the signals Andover homeowners report to us most often before a full breakdown.
- Weak or cold airflow
- Frequent short cycling
- Banging or rattling noises
- Rising fuel bills
- Cold upstairs bedrooms
- Burner that will not ignite
- Soot around the unit
If any of those sound familiar, reach out before the next cold snap turns a small repair into a no heat emergency.
Furnace Problems We Run Into Most Often
A large share of Andover homes still burn oil, and oil fired furnaces come with their own trouble spots. Clogged nozzles, worn electrodes, and dirty cad cells cause most of the lockouts we clear, and a tank that ran low over the summer can pull sediment straight into the fuel line.
On the gas side we see failed igniters, cracked flame sensors, and pressure switches tripped by a blocked flue. Older basements in town often carry long duct runs with loose joints, which starves the far end of the house and pushes the furnace to shut down on its high limit.
Thermostat trouble rounds out the list, especially in homes where a modern thermostat was wired into decades old controls. We test the full system rather than swapping parts and hoping for the best.
What Our Furnace Repair Service Covers
Every call starts with a real diagnosis. We check ignition, fuel delivery, airflow, venting, and safety controls so we can tell you what actually failed instead of guessing at it.
Once we know the cause, we walk you through the fix and the cost before any work begins. We stock common parts on the truck, which means most Andover repairs get finished the same day we arrive.
We also handle the calls where repair is no longer the smart move. If your furnace is near the end of its life, we lay out your options honestly, including oil to gas conversion for homes ready to make the switch.
A Sunday Night Call Near Andover Lake
A homeowner named Dave called us from the Andover Lake area on a Sunday night in February. His furnace was running but the house had slipped to fifty five degrees, and the cottage he had converted for year round living was losing ground fast.
Our technician found a badly fouled burner and a partially blocked flue on a system that had gone several years without service. He cleaned the burner assembly, replaced the nozzle, cleared the venting, and had steady heat moving through the house that same night.
Before heading out, he walked Dave through a simple maintenance schedule so the same thing would not repeat next winter. Visits like that are routine for us, and they are why so many families around the lake keep our number on the fridge.

Frequently Asked Questions
How fast can you get to my home in Andover?
We answer emergency calls 24 hours a day and reach most Andover homes the same day, often within a few hours of your call.
Is it worth repairing an older furnace?
Often yes. If the unit is safe and the repair is minor, fixing it makes sense. Once repairs start stacking up or efficiency drops off, replacement usually becomes the better value.
Why does my furnace run constantly but the house still feels cold?
Usually restricted airflow, a dirty burner, leaky ductwork in an unheated basement, or a failing control. A full diagnostic pinpoints which one it is.
How often should a furnace be serviced?
Once a year, ideally before heating season starts. Oil fired systems in particular benefit from an annual cleaning and tune up.
Do you service both oil and gas furnaces?
Yes. We repair oil and gas furnaces of all makes and models, and we also handle full oil to gas conversions.
