LC Heating & Air provides professional, honest gas furnace repair for Fairfax District homeowners. We prioritize safety, accurate diagnosis, and transparent, flat-rate pricing for all furnace brands.
When your furnace stops working, you need a technician who tells it like it is. I'm Leo, owner of LC Heating & Air. I’ve spent years working on the specific heating systems found here in the Fairfax District, from older multifamily units to modern rooftop package systems. I don't believe in high-pressure sales or confusing jargon. My goal is to get your heat back on safely and efficiently.
Whether your system is making a strange noise or simply refusing to ignite, we start by checking the basics. We are fully licensed (CSLB #1073586) and carry common parts like ignitors, flame sensors, and control boards on our trucks to help get you back to comfort the same day. If you're in the 90036 area, give us a call at (323) 970-3113.

Common Heating Issues in Fairfax District
In this part of Los Angeles, we see a mix of housing stock that presents unique challenges. Many older buildings have compact mechanical closets where airflow is restricted, which can cause high-limit switches to trip and shut the furnace down prematurely. We also see many rooftop package units exposed to the elements, which can lead to issues with burner ignition and venting due to debris or heat-island effects.
A common pattern I see is the 'short-cycle'—where the furnace kicks on, runs for a minute, and shuts off. This is often a sign of a dirty flame sensor or a pressure switch that isn't sensing the proper draft. Because of the density of our neighborhood, proper venting and combustion safety are non-negotiable. We always verify that your system is venting correctly so that no carbon monoxide is entering your living space.
Heating Systems in Our Neighborhood
The Fairfax District is a mix of historic homes, apartments, and modern mixed-use buildings. This variety means we work on everything from aging gas furnaces that have been running for decades to high-efficiency systems tucked into tight, shared-wall spaces.
Access is a major factor here. Between navigating HOAs, finding parking, and accessing rooftop equipment, we are used to the logistics of urban service. We plan our visits to ensure we have the right tools and access permissions before we start, so we aren't wasting your time or creating a disturbance for your neighbors.
Our Diagnostic Process
When I arrive at your door, I don't start by guessing. We follow a strict safety and combustion check first. This includes testing for CO, checking the flue draft, and inspecting the heat exchanger. If the system isn't safe to run, we won't run it.
Once we confirm the system is safe, we trace the mechanical fault. Whether it's a failed ignitor, a faulty gas valve, or a control board issue, we identify the exact part that failed. Before we turn a wrench, we provide a written estimate. You’ll know exactly what the repair costs and why it’s needed before we proceed.
Repair or Replace?
Homeowners often ask me if they should just replace an old furnace. My answer is always the same: if a repair is safe and reliable, I will fix it. I don't push for replacements just because a unit is older.
However, if the heat exchanger is cracked or the cost of repeated repairs starts to exceed the value of the unit, I’ll tell you straight. We look at the long-term reliability of your specific system. If replacement is the better path, we will explain why, but the decision is always yours.
Transparent Pricing
I believe in flat-rate pricing. You shouldn't have to worry about an hourly clock ticking while I'm working on your furnace. Our diagnostic fee is $125–$175, which includes a full safety and CO check.
Common repairs like ignitor or flame sensor replacements typically range from $100 to $300. More involved repairs like gas valves or control boards range from $300 to $600. We provide a written estimate for every job, so there are no surprises when the work is finished.
Scheduling Your Service
We know that living in the Fairfax District means dealing with parking and building access. When you call (323) 970-3113, we’ll ask about your building type and any specific access instructions. We are experienced in working with property managers and HOAs to ensure we have the clearance needed to get the job done.
We offer same-day service for most furnace repairs. Since we stock common parts on our trucks, we can often resolve issues in a single visit, saving you the hassle of multiple appointments.
Your Safety is Our Priority
A gas furnace is a powerful appliance that requires respect. Every service call includes a CO measurement and a heat exchanger inspection. We are looking for signs of incomplete combustion, such as soot or rollout switch trips, which can indicate a dangerous situation.
If you ever smell gas or notice your CO detector alarming, shut the furnace off immediately and call the SoCalGas emergency line from outside your home. Once the gas is shut off and the area is safe, call us to investigate the source of the problem.
Making the Right Choice for Your Home
Choosing an HVAC contractor shouldn't be a gamble. Look for someone who is licensed, carries insurance, and provides a clear, written estimate before starting work. You want a technician who explains the 'why' behind the repair, not just the price.
At LC Heating & Air, we focus on the details that matter—airflow, combustion safety, and part reliability. We aren't here to sell you a new system if a simple repair will keep your current one running safely for years to come.
