Common Heating Issues in Larchmont
In Larchmont, we frequently see furnace issues related to the age of the local housing stock. Many systems here are retrofitted into attics or tight crawlspaces where airflow is restricted. We often find ignitors that have failed due to age, dirty flame sensors causing the system to lock out, and draft inducer motors that have seized after years of service.
Because many of these systems were installed years ago, we also see issues with ductwork that wasn't originally designed for modern high-efficiency furnaces. If your furnace is short-cycling or failing to heat specific rooms, it is often a sign of an airflow restriction or a failing safety limit switch that needs a professional look.
Working with Larchmont’s Historic Architecture
Larchmont’s residential character is built on homes from the 1920s to 1940s. These homes were often built without central heating, meaning the HVAC systems you rely on today were added later. This creates unique challenges regarding equipment placement, duct routing, and electrical capacity.
We take extra care to ensure that any repair or service we perform respects the integrity of your home. We check for proper venting and electrical compatibility to ensure that your system is not just running, but running safely within the constraints of your home’s original design.
Our Diagnostic Process
When you call us for a furnace repair, we start by listening to your concerns. Once on-site, we perform a full system check. This includes inspecting the heat exchanger, ignitor, gas valve, control board, and blower motor. We don't just look for the immediate failure; we look for the root cause.
Safety is our first priority. Every gas furnace diagnostic includes a carbon monoxide test and a visual inspection of the heat exchanger. We want to ensure that your system is operating within safe parameters before we even discuss repair options.
Repair or Replace: An Honest Decision
One of the most common questions I get is whether a furnace is worth fixing. If a repair is minor—like a flame sensor cleaning or an ignitor replacement—it is almost always worth doing. However, if we find a cracked heat exchanger or a major component failure in a system that is 20+ years old, the repair cost might not make financial sense.
We provide an honest assessment based on the condition of your equipment. We will never push for a replacement if a reliable, safe repair is possible. If we do recommend replacement, we will explain exactly why, so you can make an informed decision for your home.
Understanding Repair Costs
We believe in upfront pricing. Our diagnostic fee is $125–$175, which includes a comprehensive safety check. Once we identify the problem, we provide a flat-rate estimate for the repair. You will know the total cost before we begin any work.
Factors that influence the cost include the specific part needed, the accessibility of the unit, and the complexity of the repair. We stock common parts like ignitors and flame sensors on our trucks to keep costs down and get your heat back on faster.
Scheduling Your Service
We know that a furnace failure in the middle of a cold snap is stressful. We prioritize emergency calls and answer the phone within 30 minutes to get you on our schedule. Whether you are in a gated property or a standard single-family home, we coordinate with you to ensure smooth access.
We serve the entire Larchmont area and surrounding neighborhoods. If you need same-day service, call us at (323) 970-3113. We will do our best to accommodate your schedule and get your home comfortable again as quickly as possible.
Avoid These Common Mistakes
The biggest mistake we see is ignoring small warning signs. A furnace that makes a banging noise at startup or smells like burning dust long after the season has started should be checked. These are often signs of delayed ignition or a dirty burner assembly that can lead to more expensive repairs later.
Another mistake is neglecting the air filter. A clogged filter restricts airflow, which causes the furnace to overheat and trip the high-limit switch. This leads to short-cycling and puts unnecessary strain on your blower motor. Check your filter every month during the heating season.
Your Safety is Our Priority
Carbon monoxide is a real danger in homes with gas appliances. Because it is colorless and odorless, you cannot detect it without a sensor. We perform a CO safety check on every furnace service call to ensure your heat exchanger is intact and venting properly.
If we find a cracked heat exchanger, we will shut the system down immediately. We also strongly recommend that every Larchmont home has working CO detectors installed outside every sleeping area. It is a small investment that provides essential protection for your family.
How to Decide on Furnace Service
If your furnace is acting up, start by checking the basics: is the thermostat set correctly, is the power switch on, and is the air filter clean? If these are fine and the system still won't run, it is time for a professional diagnostic.
When we arrive, we will evaluate the system's age, the cost of the repair, and the overall safety of the unit. We provide you with the facts so you can decide whether to invest in a repair or start planning for a new, more efficient system.

What Larchmont customers say about furnace repair
Verified reviews from homeowners in Larchmont and nearby neighborhoods who used our furnace repair service.
“Full system replacement in our 1930s Hancock Park home — not easy given the older construction. LC handled all the challenges: narrow access, old ductwork, low attic. Finished on time and on budget.”
“AC compressor failed on the hottest day of the year. LC came out quickly, gave an honest assessment — said the compressor was still under manufacturer warranty — and helped me get it covered. Saved me over $1,200.”
“Replaced our 20-year-old Lennox system with a new high-efficiency Carrier. LC handled the permits, coordinated the Edison inspection, and finished a full replacement in one day. Impeccable workmanship.”
