Full furnace replacement — properly sized, permitted, and installed to last. LC Heating & Air provides honest, professional service for Century City homeowners.
When your furnace starts acting up, you need a straight answer about whether it's worth fixing or if it's time for a new one. I'm Leo, owner of LC Heating & Air, and I've spent years working in the unique housing stock of Century City. Whether you are in a high-rise, a condo, or a single-family home, I approach every job by looking at the equipment, the safety, and the long-term cost to you.
My goal isn't to sell you a new unit if your current one has plenty of life left. But if your system is failing, leaking, or just plain dangerous, I will tell you exactly why. We handle everything from the initial Manual J heat load calculation to pulling the required permits, ensuring your home stays safe and comfortable.

Century City Housing and HVAC Challenges
Century City presents unique challenges for HVAC work. Between the dense mix of high-end condos, apartments, and older multifamily buildings, we often deal with tight mechanical closets, rooftop package units, and shared walls. These spaces require careful coordination with building management and HOAs to ensure we have the right access for repairs or replacements.
Because of the local climate, many systems here are exposed to heat-island effects from parking lots and limited ventilation. This puts extra strain on equipment. When I inspect a system, I look for signs of heat-related stress, such as prematurely worn capacitors or restricted airflow caused by poor duct design in compact spaces.
How We Assess Your Furnace
I don't believe in guessing. When I arrive, I start by checking the basics: ignition, burners, and flame sensing. I also look closely at the venting and combustion safety. Carbon monoxide is a real risk, so verifying that your flue is clear and your system is venting properly is my top priority.
After the safety check, I look at the airflow and duct leakage. If your furnace is struggling, it might not be the unit itself—it could be the ductwork. We verify the combustion air supply and measure temperature rise to see if the system is performing within the manufacturer's specifications.
Repair or Replace: Making the Right Call
The decision to replace a furnace should be based on math and safety, not pressure. If your furnace is 15 to 20 years old and the repair cost is significant, it's usually time to look at a replacement. You don't want to keep sinking money into a system that is nearing the end of its life.
If the heat exchanger is cracked, that is a non-negotiable safety issue. In that case, replacement is the only responsible path. However, if it's a simple part failure on a well-maintained unit, I'll tell you to keep it running. My job is to give you the information you need to make the decision that makes sense for your budget.
Understanding Costs and Incentives
I know that furnace replacement is a major expense. That's why I provide written estimates that break down the costs clearly. We also help you navigate available incentives, such as the TECH Clean California program and SoCalGas rebates, which can help offset the cost of high-efficiency equipment.
When we look at the numbers, we consider the payback period. A 96% AFUE unit costs more upfront than an 80% unit, but the energy savings over time can make it the better choice. We show you the actual math for your home so you can decide if the efficiency gains are worth the investment.
Scheduling and Building Access
In Century City, access is half the battle. Whether we are dealing with a rooftop unit on a commercial building or a closet unit in a high-rise, we plan for the logistics before we start. We understand the need to coordinate with building management and HOAs regarding parking, service elevators, and noise restrictions.
We respect your time and your building's rules. By planning the access and the installation sequence ahead of time, we minimize the disruption to your day and ensure the job gets done right the first time.
Avoid These Common HVAC Mistakes
The biggest mistake I see is 'rule of thumb' sizing. Many contractors just replace your old furnace with one of the same size without checking if the original was even sized correctly. In our mild climate, many homes are actually oversized, which leads to short-cycling. This wastes fuel and wears out your equipment faster.
Another mistake is skipping the permit. Furnace work involves gas lines and venting; it must be inspected to ensure it meets safety codes. Never let anyone talk you out of a permit—it's there to protect you and your home.
Your Safety is Our Priority
Your furnace is a combustion appliance. If it isn't venting correctly, it can leak carbon monoxide into your home. This is why we perform a thorough safety check on every visit. We verify the flue condition, check for proper combustion air, and make sure the system is operating safely.
If we find a cracked heat exchanger or a venting issue that poses a risk, we will shut the system down and explain the danger immediately. We don't cut corners on safety—ever.
Frequently Asked Questions
How long do furnaces last in Los Angeles? With annual maintenance, most gas furnaces last 18–25 years. LA furnaces work far fewer hours than in colder climates, which helps, but parts still degrade over time.
Do I need a permit to replace my furnace? Yes. Any work involving gas connections and venting requires a permit and inspection to ensure safety and compliance with building codes.
Should I replace my furnace and AC at the same time? If your AC is also aging, doing both at once saves on mobilization costs and ensures the systems are matched for efficiency.
Can you replace my furnace with a heat pump? Yes. Many LA homes are great candidates for heat pumps, which provide both heating and cooling and qualify for significant state and federal incentives.
The LC Heating & Air Approach
When you call us, you aren't getting a salesperson—you're getting a technician. I look at your system, test the components, and tell you exactly what I find. If a repair will get you through the next few years, I'll tell you. If the system is a safety hazard or a money pit, I'll show you why.
We believe in doing things the right way: pulling permits, performing Manual J calculations, and verifying every connection. We want you to be comfortable, but more importantly, we want you to be safe.
How the visit works
We inspect your current system, flue condition, combustion air supply, and ductwork, then perform a Manual J heat loss calculation.
We present 2–3 options at different efficiency levels with rebate information and honest payback analysis.
A licensed technician removes the old unit, handles gas line connections, updates venting if required, and installs the new furnace.
We test combustion, measure temperature rise, verify CO output, and walk you through the new system before leaving.
