I’m Leo, owner of LC Heating & Air. I’ve spent enough time in San Marino to know that these homes—whether they are historic custom builds or hillside properties—have unique mechanical needs. When you live in an area with varied elevation and specific architectural constraints, your HVAC system works harder than you might realize. My goal is to keep your system running reliably so you aren't left without cooling on a 95-degree day.
Maintenance isn't just about changing a filter. It’s about catching the small, inexpensive parts—like a $35 capacitor—before they fail and take out a $2,000 compressor. We provide clear, plain-spoken service that helps you decide when a repair is the right move and when it’s time to consider a replacement. We are licensed (CSLB #1073586) and ready to help you keep your home comfortable.

Why San Marino Homes Need Specific Maintenance
San Marino’s geography creates specific challenges for HVAC systems. Between the hillside slopes, canyon properties, and mature tree cover, airflow and equipment placement are rarely straightforward. We often see systems struggling because of restricted service clearances or line-set routing that wasn't optimized for the property’s layout. If your outdoor unit is tucked into a tight, poorly ventilated area, it has to work much harder to reject heat, which leads to premature component wear.
We also see room-by-room comfort issues caused by sun exposure and elevation changes. During our maintenance visits, we don't just look at the furnace or AC unit; we look at how the system is actually performing within the context of your home. If your system is cycling too frequently or taking too long to reach the target temperature, it’s often a sign that the system is fighting against the home's unique environmental factors.
Working with Older and Custom Homes
San Marino is home to many older custom properties and estate lots. These homes often have mechanical areas that were designed decades ago, which can make modern equipment upgrades or even basic maintenance access a challenge. We are used to working in tight-access mechanical areas and navigating the complexities of older ductwork.
If you have an older system, maintenance is even more critical. We check for signs of aging that could lead to safety issues, such as heat exchanger integrity or electrical connection degradation. We’ll tell you honestly if your system is worth the cost of a repair or if the age and condition of the equipment make replacement the more practical long-term investment.
Our 21-Point Inspection Process
When we arrive at your home, we follow a strict 21-point protocol. We check the electrical connections, test the capacitors and contactors, measure the blower motor amp draw, and inspect the evaporator and condenser coils. We also perform a combustion analysis and CO testing on all gas heating systems—safety is not optional.
After the inspection, I provide a written report. If I find a part that is wearing out, I’ll show you why it matters and give you a price for the repair before we touch anything. You are never pressured into work you don't need.
The Honest Repair vs. Replace Decision
One of the most common questions I get is, 'Leo, should I fix this or just get a new one?' My answer depends on the math and the condition of your equipment. If a repair is minor and the system has plenty of life left, I’ll tell you to fix it. If the system is aging, inefficient, and the repair cost is a significant percentage of a new unit, I’ll be honest about that, too.
We don't push for replacement unless it's the right financial move for you. We want to be the contractor you trust for the long haul, which means giving you the straight truth, even if it means we don't sell a new system today.
Understanding Costs
We believe in transparent pricing. Our diagnostic and inspection fees range from $125–$200, and standard maintenance tune-ups are $89–$175. If you need a full system replacement, those projects typically range from $6,000 to $18,000+ depending on the complexity of the installation and the equipment required.
We don't hide costs in fine print. We provide written estimates for every job so you know exactly what you are paying for before we start.
Scheduling for San Marino
We know that San Marino residents have busy schedules. We prioritize our maintenance agreement customers, ensuring you get on the calendar before the peak heat of summer or the first cold snap of winter. Because of the unique access requirements in many local neighborhoods, we always plan our arrival with the specific property layout in mind.
If you need us, call (323) 970-3113. We’ll get you on the schedule and make sure we have the right information about your property access before we head out.
Mistakes Homeowners Make
The biggest mistake I see is waiting until the system stops working to call for help. By then, a simple $35 capacitor failure has often caused a compressor to overheat, turning a minor repair into a major expense. Another common mistake is ignoring small changes in sound or performance. If your system sounds different or is taking longer to cool your home, it’s telling you something is wrong.
Also, don't forget your filters. Replacing them every 1–3 months is the single best thing you can do for your system between our visits. During wildfire season, check them monthly.
Your Safety is Our Priority
HVAC systems involve high-voltage electricity, pressurized refrigerant, and, in many cases, natural gas. We take safety seriously. Every heating system visit includes a combustion analysis and carbon monoxide testing. We don't skip these steps. We want to ensure your home is not just comfortable, but safe for your family.
As a C-20 licensed contractor, we follow all local codes and safety standards. We don't cut corners, and we don't ignore potential hazards.
Is Maintenance Right for You?
If you value reliability and want to avoid the stress of a breakdown, maintenance is the right choice. It’s an investment that pays for itself by extending the life of your equipment and keeping your energy bills lower.
If you are unsure about the state of your system, give us a call. We can perform an inspection and give you a clear, honest assessment of what your HVAC system needs to keep your home comfortable.

What San Marino customers say about hvac maintenance
Verified reviews from homeowners in San Marino and nearby neighborhoods who used our hvac maintenance service.
“AC wasn't cooling to setpoint even though it was running all day. LC found the condenser coils were completely clogged with cottonwood. Cleaned them on the spot and the system cooled my house 12 degrees in an hour.”
“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
