Full HVAC system replacement, including heating and cooling, properly sized and permitted for your Hollywood Hills home.
I'm Leo, owner of LC Heating & Air. When you're looking at a full HVAC replacement in the Hollywood Hills, you aren't just buying a piece of equipment; you're solving a comfort problem that’s likely been building up for years. Whether you're dealing with an aging furnace and AC that can't keep up with our local heat or you're looking to switch to a high-efficiency heat pump, I believe in giving you the straight facts on what your home actually needs.
Our approach is simple: we look at your specific property, the ductwork, and the electrical capacity before we ever talk about a specific model. We don't believe in one-size-fits-all solutions. If a repair makes sense, I’ll tell you. If the system is at the end of its life and replacement is the smarter financial move, I’ll explain why so you can make an informed decision for your home.

Common HVAC Challenges in Hollywood Hills
Living in the Hollywood Hills means dealing with unique terrain. Between the slope, the sun exposure, and the way these homes are tucked into canyons, we see a lot of systems that were never sized correctly for the specific room-by-room comfort needs of the house. If you have hot spots or rooms that never seem to get enough airflow, it’s often a combination of undersized ductwork and equipment that wasn't designed for the home's orientation.
Access is the other big factor here. Many of our hillside homes have tight mechanical areas, tricky ladder access, or long line-set runs that make maintenance difficult. When we plan a replacement, we don't just look at the unit; we look at how it fits into your specific space. We make sure the new system is accessible for future service so you aren't paying extra just because a technician can't reach a component.
Working with Hollywood Hills Architecture
The Hollywood Hills has a mix of older custom homes and modern estate lots. In older homes, the ductwork is often the weak link. You can put the most efficient furnace on the market in a house, but if the ducts are leaking or undersized, you’re still going to have comfort issues and high energy bills. We inspect the condition of your existing ductwork as part of our assessment.
We also see many homes where the electrical panel is a limiting factor. If you're considering a heat pump, we need to make sure your electrical service can handle the load. We check this upfront so you don't run into surprises during the installation process.
Our Diagnostic and Assessment Process
Before we suggest a replacement, we perform a full Manual J load calculation. This is the industry standard for determining exactly how much heating and cooling your home requires based on your insulation, window placement, and local climate. It takes the guesswork out of the equation.
We also look at the entire system as a whole. We check refrigerant levels, airflow at every register, and the condition of your gas lines and electrical connections. By the time we finish our assessment, you’ll have a clear picture of why your current system is struggling and exactly what it will take to fix it.
Making the Decision: Repair or Replace?
This is the conversation I have most often at kitchen tables. If your system is 10 years old and needs a minor repair, we fix it. But if your furnace is 15–20 years old and the AC is 12–15 years old, you’re likely throwing good money after bad. Every time we come out for a repair, you're paying for the trip and the labor. If you replace both at once, you pay for one mobilization, and you get a matched, warranted system.
We also look at the long-term cost. If your energy bills are consistently high because of an inefficient system, the monthly savings from a new, high-efficiency unit can often offset a good portion of the replacement cost over time. We provide a written estimate so you can see the numbers for yourself.
Understanding Costs and Incentives
A full HVAC replacement in Los Angeles typically ranges from $7,500 to $14,000, depending on the equipment size, efficiency, and the ductwork modifications required. While that's a significant investment, there are ways to manage it. We help you navigate available rebates, including TECH Clean California and federal tax credits for heat pumps.
We don't believe in hidden fees. Our estimates are transparent, and we explain exactly what is included—from the permit fees to the final commissioning report. You’ll know exactly what you’re paying for before we start.
Safety and Performance
Safety is non-negotiable. When we install a new furnace, we ensure proper venting and gas line integrity. If we're installing a heat pump, we make sure the electrical connections are up to code. We don't cut corners on the technical details that keep your home safe.
Performance is about more than just the equipment. It’s about how it’s installed. We include full commissioning, which means we verify the refrigerant charge and airflow after the unit is in place. This ensures the system actually delivers the efficiency you paid for.
Scheduling Your Replacement
We know that having a crew in your home is an inconvenience. Most full replacements in homes with existing ductwork are completed in one day, usually between 6 and 10 hours. If we need to do extensive ductwork repairs, it might take two days, but we will tell you that upfront in the proposal.
We work with your schedule to minimize the disruption. Our goal is to get in, get the job done right, and get out, leaving your home as clean as we found it.
Mistakes to Avoid
The biggest mistake I see is homeowners replacing an AC unit without checking the furnace or the ductwork. If you put a new, high-efficiency AC on an old, restrictive furnace blower, you won't get the efficiency you paid for. It’s like putting a racing engine in a car with a flat tire.
Another mistake is skipping the load calculation. If a contractor just replaces your old unit with one of the same size without checking if the old one was sized correctly, you might be repeating the same comfort problems you had before. We always calculate the load to ensure the new system is the right fit for your home.
Is it Time to Replace?
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 serious conversation about replacement. We look at the repair history, the age of the components, and your comfort goals.
If you're planning a major renovation, that’s the perfect time to address the HVAC system. It’s much easier to modify ductwork or upgrade electrical capacity when walls are open or the house is already being worked on. Call us at (323) 970-3113 to discuss your specific situation.
