I'm Leo, owner of LC Heating & Air. When you call us about your furnace, I'm not looking for a quick sale. I'm looking at your system the same way I would if it were in my own home. In Sylmar, we see a lot of mixed-age housing, from older homes with original setups to newer remodels. Each one has different needs when it comes to heating.
My job is to tell you the truth about your equipment. Sometimes a simple repair is all you need to get through the winter. Other times, the age and condition of the unit mean that replacing it is the only way to keep your home safe and comfortable. We handle the permitting, the sizing, and the installation so you don't have to worry about the details.
Emergency calls are answered within 30 minutes — call (323) 970-3113 for dispatch.
Local HVAC considerations
Common Heating Issues in Sylmar
In Sylmar, we deal with a specific set of challenges. Because our climate is mild, furnaces often sit idle for long stretches. This can lead to dust buildup, burner issues, and flame sensor problems when the weather finally turns cold. We also see many older systems that were never sized correctly for the home in the first place.
Another pattern I see is the 'short-cycling' furnace. If your system turns on and off every few minutes, it’s likely oversized or struggling with airflow issues. This puts unnecessary wear on your components and drives up your gas bill. We check your ductwork and airflow during every diagnostic visit to see if the problem is the furnace itself or how it's interacting with your home.
Understanding Your Home's Needs
Sylmar has a mix of single-family homes and smaller multifamily buildings. Older homes often have ductwork that wasn't designed for modern, high-efficiency equipment. If you just swap out a furnace without checking the ducts, you might end up with a noisy system that doesn't heat evenly.
We look at the whole picture. Before we recommend a replacement, we check your electrical, the flue condition, and the physical space available. If your home has been remodeled, the heating requirements may have changed. We don't guess; we measure.
Our Diagnostic Process
When I come out for a service call, I start with the basics: ignition, burners, and flame sensing. I want to see if the system is actually firing correctly. I also perform a CO safety check, which is non-negotiable. If your heat exchanger is cracked, it’s a safety hazard that needs immediate attention.
After the safety check, I look at the system's history. Has it been repaired three times in the last two years? Is it struggling to maintain temperature? I’ll explain exactly what I find so you can see the same things I see. You’ll get a written estimate before we do any work.
Repair vs. Replace: Making the Right Call
This is the most important conversation we have. If your furnace is 15–20 years old and the repair is going to cost a significant portion of a new unit, I’m going to recommend replacement. It doesn't make sense to put expensive parts into a system that is at the end of its life.
However, if your furnace is younger and the repair is straightforward, I’ll tell you to fix it. My goal is to save you money in the long run. If the pattern of failures suggests the unit is failing, I’ll show you the numbers so you can decide what’s best for your budget.
Costs, Rebates, and Value
I know that replacing a furnace is a major expense. That’s why we help you navigate the TECH Clean California and SoCalGas rebate programs. If you choose a high-efficiency unit, these incentives can help offset the upfront cost.
We provide clear, upfront pricing. You won't find hidden fees or surprise charges on our invoices. We also provide a payback analysis so you can see how long it will take for a higher-efficiency unit to pay for itself through lower energy bills.
Safety First: Permits and Combustion
Furnace work isn't just about heat; it's about safety. Gas connections and venting must be done to code. That’s why we pull a permit for every replacement. It ensures that a city inspector verifies the work, which protects your home and your family.
We also verify combustion air. A furnace needs to 'breathe' to burn gas safely. If your home is sealed up tight, we need to make sure the furnace has enough air to operate without producing carbon monoxide. We don't cut corners on safety.
Scheduling and Access
We know your time is valuable. We work with you to find a time that fits your schedule. When we arrive, we respect your home. We check the access points, electrical setup, and ductwork to ensure the installation goes smoothly.
If you have an emergency, let us know. We prioritize safety-related issues like gas leaks or carbon monoxide concerns. For standard replacements, we’ll give you a clear timeline so you know exactly when your home will be comfortable again.
Mistakes to Avoid
The biggest mistake I see is 'rule of thumb' sizing. A contractor who just looks at the size of your old furnace and installs the same size is doing you a disservice. Every home is different, and modern furnaces are often more efficient than older ones. If you don't do a Manual J calculation, you risk buying a unit that is too large, which leads to short-cycling and wasted money.
Another mistake is skipping the permit. Unpermitted work is a red flag if you ever decide to sell your home, and it means the work wasn't inspected for safety. Always insist on a permit.
How to Decide
When you're looking at your furnace, ask yourself: Is it keeping the house comfortable? Is it making strange noises? Is it costing more to run every year? If the answer is yes, it’s time for a professional look.

What Sylmar customers say about furnace replacement
Verified reviews from homeowners in Sylmar and nearby neighborhoods who used our furnace replacement service.
“Furnace was making a loud banging noise every time it started. LC diagnosed delayed ignition from dirty burners. Cleaned and tuned the whole system, tested CO levels, explained everything clearly. No upsell, fair price.”
“Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.”
