I'm Leo, owner of LC Heating & Air. When you're looking at HVAC replacement in San Marino, you aren't just buying a box of parts; you're investing in how your home feels for the next fifteen years.

Common HVAC Issues in San Marino
San Marino homes present unique challenges. Because of the hillside terrain and varying tree cover, we often see significant room-by-room temperature differences. If your current system was installed years ago, it might not have been sized for your home's specific orientation or insulation levels. We often find that older systems struggle because they are fighting against poor airflow or leaky ducts that were never properly sealed.
Another pattern we see is the 'patchwork' repair. When a system is 15 or 20 years old, replacing one part often puts extra strain on another aging component. We see homeowners spend money on a new blower motor only to have the condenser fail a few months later. That is why we look at the whole system before recommending a repair or a full replacement.
Working with San Marino's Unique Architecture
San Marino has a beautiful mix of older custom homes and estate properties. These homes often have tight-access mechanical areas that make maintenance and replacement tricky. When we plan a replacement, we have to account for ladder access, line-set routing, and service clearances. If the equipment is tucked into a difficult spot, we make sure the new system is installed so that future technicians can actually reach it for routine service.
We respect the character of your home. Whether your equipment is in a basement, an attic, or a tight outdoor space, we plan the installation to minimize disruption while ensuring the system has the airflow it needs to run efficiently.
Our Diagnostic and Planning Process
Before we ever suggest a new unit, we perform a full assessment. We don't guess. We perform a Manual J load calculation to determine exactly how much heating and cooling your home requires based on your windows, insulation, and local climate. This ensures you aren't paying for a system that is too big or too small.
We also inspect your ductwork. A high-efficiency unit is only as good as the ducts it pushes air through. If we find leaks or obstructions, we include those repairs in our plan. We want you to have a system that performs, not just a shiny new box that struggles against bad ductwork.
Repair or Replace? An Honest Decision
I tell every homeowner the same thing: if a repair makes sense, I'll tell you. But if your system is 15+ years old and the repair cost is high, you're just delaying the inevitable. Replacing both the furnace and the AC at the same time is often the most economical choice because you only pay for one mobilization and one installation project.
We also discuss heat pump technology. For our mild San Marino climate, a heat pump is often a fantastic, efficient alternative to a traditional gas furnace and AC split system. We will walk you through the pros and cons so you can decide what fits your budget and your long-term plans for the house.
Understanding Costs and Incentives
Full HVAC replacement costs generally range from $7,500 to $14,000, depending on the equipment, ductwork needs, and the complexity of the installation. I know that's a significant investment, which is why we focus on maximizing your rebate potential.
Programs like TECH Clean California and federal tax credits can significantly lower your out-of-pocket costs, especially if you choose a high-efficiency heat pump. We handle the documentation for these programs so you don't have to worry about the paperwork. We provide a clear, written estimate before we start, so there are no surprises.
Scheduling Your Replacement
We know your time is valuable. Most full system replacements in San Marino are completed in a single day, usually within 6 to 10 hours. If your home requires extensive ductwork repairs, we might need a second day, but we will tell you that upfront in the proposal.
Because of the narrow roads and hillside access in some parts of San Marino, we plan our logistics carefully. We make sure our crew has the right equipment and access to get the job done safely and efficiently without blocking your neighbors or causing unnecessary noise.
Mistakes We See (And How We Avoid Them)
The biggest mistake is skipping the Manual J load calculation. Many contractors just replace 'like for like'—putting in the same size unit that was there before. But if your home has been renovated, or if the old unit was sized wrong in the first place, you'll end up with hot spots and high energy bills.
Another mistake is ignoring the electrical capacity. If you're switching to a heat pump, your electrical panel needs to be able to handle the load. We check your electrical service during our initial assessment so we don't run into a surprise on installation day.
Safety and Commissioning
Safety is the priority. When we install a new system, we verify the refrigerant charge, check all electrical connections, and ensure the system is properly vented. We don't just turn it on and leave; we perform a full commissioning process.
This includes measuring airflow at every register to ensure the system is balanced. We provide you with a written performance report so you know exactly how your new system is running. We want you to have peace of mind that your home is safe and comfortable.
Is It Time for a New System?
If your equipment is over 12 years old and you're calling for repairs more than once a year, it's time to have a conversation. You shouldn't be throwing good money after bad. We look at the total cost of ownership—what you're spending on repairs versus what you'd spend on a new, efficient system that comes with a warranty.
If you're planning a major renovation or just want to improve your home's comfort, a full system replacement is often the best path forward. We'll give you the facts, show you the options, and let you make the decision that's right for your family.

What San Marino customers say about hvac replacement
Verified reviews from homeowners in San Marino and nearby neighborhoods who used our hvac replacement 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.”
