Full AC system replacement — properly sized, permitted, and warrantied.
I'm Leo, owner of LC Heating & Air. When you're looking at an AC replacement, you aren't just buying a piece of equipment; you're buying a system that needs to work for your specific home. In Los Angeles, we deal with everything from tight attic spaces and older electrical panels to the intense heat that tests every component. My job is to make sure you get a system that is sized correctly for your square footage and insulation, not just a box that fits in the same spot as the old one.
We don't believe in high-pressure sales. We believe in showing you the math. Whether you're dealing with a system that's finally reached the end of its life or you're tired of high energy bills and constant repairs, we provide the honest analysis you need to make the right decision for your home and your budget.

When Repair No Longer Makes Sense
At some point, repairing an aging air conditioner stops being the smart financial move. The general rule: if a repair costs more than half the price of a new system, and your unit is 10 or more years old, replacement is typically the better investment. You stop throwing money at a declining system and start banking the energy savings a modern, high-efficiency unit delivers from day one.
We often see systems in Los Angeles that are struggling due to age and the local climate. If your AC is 12–15+ years old, uses the phased-out R-22 refrigerant, or simply can't keep up when temperatures climb above 90°F, it's time to have a real conversation about replacement. We look at your repair history, utility bills, and the current condition of your ductwork to see if a new unit will actually solve your comfort problems.
Los Angeles Housing and HVAC Challenges
Los Angeles has a unique mix of housing, from older single-family homes to small multifamily buildings and recent remodels. This variety means that no two installations are exactly the same. We often encounter older electrical layouts, limited attic access, and ductwork that needs attention to ensure proper airflow.
Before we recommend a new unit, we check your electrical panel, duct condition, and equipment placement. If your ducts are leaking or undersized, even the most efficient AC won't perform well. We make sure the entire system is set up to succeed, not just the condenser outside.
Our Replacement Process
We start with a free replacement assessment. We don't just look at the unit; we measure your home's insulation, window orientation, and ceiling heights to perform a Manual J load calculation. This ensures your new system is sized perfectly for your home's actual cooling needs.
Once we have the data, we present 2–3 equipment options. We explain the trade-offs between efficiency levels and help you understand the potential rebates from SCE, SoCalGas, and TECH Clean California. When you choose an option, we handle the permit process with LADBS and schedule the final inspection. On installation day, our crew removes the old system, recovers the refrigerant per EPA 608 regulations, and installs your new unit to manufacturer standards.
The 50% Rule
Homeowners often ask me, 'Leo, should I fix it or replace it?' My answer is always the same: let's look at the numbers. If your system is over 10 years old and the repair cost is more than 50% of what a new unit would cost, replacement is almost always the better financial choice. You're avoiding the risk of the next component failing shortly after the first repair.
We won't push you toward a new system if a repair is the right move. If your unit is in good shape and just needs a minor part, we'll tell you. We want to be the contractor you trust for the long haul, not just for one sale.
Understanding Your Investment
The cost of a new system depends on the efficiency tier, the complexity of the installation, and the equipment brand. We offer transparent, written estimates so you know exactly what you're paying for before we start. We also help you navigate available rebates, which can range from $500 to $3,000 depending on the equipment you choose.
Remember that a proper installation includes the cost of permits and professional commissioning. These aren't just extra steps; they are essential for your warranty and for the safety and longevity of your new system.
Mistakes We See Often
The biggest mistake we see is 'rule of thumb' sizing. Some contractors just replace a 3-ton unit with another 3-ton unit without checking if the home's insulation or window layout has changed. This leads to short-cycling, where the unit turns on and off too frequently, which wastes energy and leaves your home feeling humid.
Another common issue is skipping the permit. Unpermitted work can cause major headaches when you try to sell your home or if you have an insurance claim. We never skip the permit process. It's there to protect you and ensure the work is done to code.
Safety and Compliance
Safety is non-negotiable. When we replace an AC system, we ensure all electrical connections meet current code. We also properly recover all old refrigerant using EPA 608-compliant equipment. Refrigerant is a regulated substance and cannot be vented into the atmosphere.
By pulling permits and ensuring the final inspection is completed, we make sure your home's HVAC system is safe, efficient, and compliant with local regulations. You get peace of mind knowing the job was done right.
Is It Time to Replace?
Deciding to replace your AC is a big decision. We look at the age of your system, the frequency of repairs, and your current energy bills. If your system is over 10 years old and the repair costs are adding up, it's often more cost-effective to upgrade to a modern, efficient unit.
We'll walk you through the options, explain the efficiency ratings, and help you understand the long-term savings. Our goal is to give you all the information you need to make a decision you'll be happy with for years to come.
How the visit works
Free replacement assessment: We inspect your current system, ductwork, electrical panel, and insulation before recommending any equipment.
Equipment proposal: We present 2–3 equipment options at different efficiency levels with honest payback analysis and applicable rebates.
Installation day: A two-tech crew removes the old system, handles refrigerant recovery, and installs the new unit to manufacturer spec.
Commission and warranty: We measure refrigerant charge, test all functions, register your warranty, and review the system with you before leaving.
Cost factors we review before quoting
- • Equipment efficiency and SEER2 ratings
- • Ductwork condition and necessary repairs
