Warning Signs Your
Heating System Needs
Repair Now

Most heating failures in Westchester don't happen without warning. Catching a problem in October is a scheduling call. Catching it in January at 11pm is an emergency. Here's what to watch for.

📞 Call 914-762-9600
  • !
    No Heat or Insufficient Heat Your thermostat is set correctly but your home isn't reaching temperature, or heat is only reaching some rooms. This can indicate a failed heat exchanger, burner problem, blocked flue, or a hydronic system issue.
  • !
    Furnace or Boiler Won't Turn On The system isn't responding to the thermostat at all. Common causes include a failed igniter, tripped safety switch, thermostat fault, or a loss of power or gas supply to the unit.
  • !
    Unusual Noises — Banging, Rumbling, or Squealing Banging on startup often means delayed ignition in a furnace or water hammer in a steam boiler. Rumbling during operation typically points to burner issues. Squealing suggests a blower motor or belt problem. None of these should be ignored.
  • !
    Short Cycling — System Turns On and Off Repeatedly A heating system that runs in short bursts and never reaches your set temperature is short cycling — often caused by an overheating limit switch, a dirty filter, or a malfunctioning thermostat. Left unchecked, it dramatically shortens equipment life.
  • !
    Spiking Heating Bills A sudden and unexplained increase in your gas or oil bill without a change in usage usually means your heating system is working significantly harder than it should — a reliable sign of a developing problem.
  • !
    Yellow or Flickering Burner Flame A healthy gas furnace flame should be solid blue. A yellow or orange flame can indicate incomplete combustion and potential carbon monoxide production — this requires immediate attention. Call us right away.
  • !
    Water or Leaks Around the System Water pooling around a furnace may indicate a condensate drainage problem on a high-efficiency unit. Water around a boiler can mean a leak in piping, a failed expansion tank, or a pressure relief valve discharging — all require prompt service.
What to Expect

Our Heating Repair Process

From the moment you call to the moment your heat is back on, here's exactly how a Carey & Walsh heating repair visit works.

01
📞
Call Anytime — 24/7

Call 914-762-9600 any time. Emergency calls are dispatched immediately. Non-emergency calls are scheduled same-day when available. We'll give you an arrival window and let you know if it's an emergency dispatch.

02
🔍
Accurate Diagnosis First

Our technician performs a thorough inspection of your system before recommending any repair. We look at every component involved — not just the most obvious failure point — to make sure we're fixing the actual problem, not a symptom.

03
📋
Written Estimate — No Surprises

After diagnosis, you receive a clear written estimate with parts and labor broken out. We don't start work without your approval. The price we quote is the price you pay — no surprise charges added after the fact.

04
🔧
Repair on the First Visit

Our vehicles carry common furnace parts, boiler components, and electrical supplies so most repairs are completed on the same visit. When a part needs to be ordered, we're upfront about the timeline and prioritize getting it quickly.

05
Full System Test

Once the repair is complete, we run the full system through a heating cycle — verifying operation of the burner, heat exchanger or heat transfer, controls, and safety switches. We don't leave until the system is confirmed working correctly.

06
🛡️
Repair Warranty

All repairs come with a workmanship warranty. If the same issue returns after our service, we'll make it right. We can also set you up on an Energy Savings Agreement for annual maintenance that prevents most breakdowns before they happen.

Call 914-762-9600
Why is my furnace not working?
The most common reasons a furnace stops working include: a failed igniter or flame sensor (won't start or starts then shuts off), a tripped high-limit switch (often caused by a clogged filter restricting airflow), a faulty thermostat or dead batteries, a tripped circuit breaker, a problem with the gas supply, or a cracked heat exchanger triggering a safety shutoff. Before calling, check your thermostat settings, replace the filter if it's dirty, and check your circuit breaker. If those aren't the issue, call 914-762-9600 for same-day diagnosis across all of Westchester County.
Furnace repair costs in Westchester depend on what needs fixing. Simple fixes like an igniter or flame sensor replacement are on the lower end, while component replacements like a limit switch, gas valve, or inducer motor represent a more involved repair. A cracked heat exchanger is more serious — repair costs vary but it often makes replacement the better investment for older systems. We provide a full written estimate before beginning any work, so you'll know exactly what you're paying before we start.
Yes. Carey & Walsh provides 24-hour emergency heating repair throughout Westchester, Putnam, and Rockland counties — including nights, weekends, and holidays. Call 914-762-9600 any time. We repair furnaces, boilers, heat pumps, and ductless heating systems under emergency conditions and dispatch as quickly as possible.
Banging or "water hammer" in a steam boiler is usually caused by water sitting in a horizontal steam pipe — a pitch or trap issue that forces steam and water to collide. In a hot-water system, banging can indicate air trapped in the pipes or a failing circulator pump. Deep rumbling during operation typically points to sediment buildup in the boiler or a burner combustion problem. All of these need professional diagnosis before they cause more significant damage. Call 914-762-9600 for a same-day boiler inspection.
The right decision usually comes down to weighing your system's age against the scope of the repair needed. An older furnace facing a significant repair is often a strong candidate for replacement — especially when a new high-efficiency system will deliver lower monthly heating bills and come with a manufacturer's warranty. A newer system with a relatively minor issue, on the other hand, is almost always worth repairing. We give honest advice based on your system's specific condition, age, and repair history — no pressure toward either option.
Yes — a severely clogged air filter is one of the most common and most preventable causes of furnace breakdowns. When airflow is restricted, the furnace overheats and the high-limit safety switch trips, shutting the system down. If your furnace is short-cycling (turning on briefly then shutting off), check and replace your filter first. If a fresh filter doesn't resolve it, the high-limit switch itself may have been damaged by repeated overheating. Filters should be replaced every 1–3 months during the heating season.
Yes. Oil-fired furnaces and boilers remain common across Westchester County, particularly in older homes. We repair, maintain, and replace oil heating systems — including burner cleaning, nozzle replacement, oil pump repair, electrode service, and flue inspection. We can also evaluate whether an oil-to-gas conversion makes financial sense for your home, given the significant operating cost savings it often provides.
