Replacing your entire HVAC system—both heating and cooling—is the right move when systems are aging simultaneously, or when upgrading to heat pump technology. LC Heating & Air performs complete HVAC replacements throughout Agoura Hills with proper sizing, permits, and commissioning.
HVAC Repair & Service in Agoura Hills
LC Heating & Air provides HVAC service in Agoura Hills — including HVAC services near me, HVAC repair and service, heating and air conditioning, HVAC system repair. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.
We repair and service all major HVAC brands in Agoura Hills, including Carrier, Lennox, Trane, Goodman, Daikin, and Mitsubishi, and older or discontinued units. No matter the manufacturer, we diagnose the problem accurately and give you an upfront price before any work begins.
When your AC reaches 12–15 years old and your furnace is 15–20 years old, replacing both at the same time has significant advantages. You pay one mobilization cost instead of two. Modern split systems are designed as matched pairs—the AC condenser and air handler are engineered together. Mismatched components often reduce efficiency and can create warranty complications.
At LC Heating & Air, I don't believe in pushing for a replacement unless it makes financial and practical sense for your home. If a repair will keep your system running safely and efficiently, I will tell you. If the pattern of repairs suggests you are throwing good money after bad, I will explain why replacement is the better long-term investment.

The Agoura Hills Hillside Challenge
Agoura Hills presents unique challenges for HVAC systems. Because of our hillside homes, canyon properties, and estate lots, equipment placement is rarely straightforward. We have to account for slope, sun exposure, and tree cover, which often lead to room-by-room comfort differences that a generic system just cannot handle.
I pay close attention to how your home is situated. If your ductwork runs are long or your mechanical area is in a tight-access space, the design of the system matters as much as the equipment itself. We plan for ladder access, line-set routing, and service clearances before we start any work to ensure your new system is actually serviceable in the future.
Older Custom Homes and Modern Efficiency
Agoura Hills has a mix of older custom homes and newer developments. In older properties, we often find that the original ductwork is undersized for modern, high-efficiency equipment. Simply swapping out the condenser and furnace without checking the ducts is a common mistake that leads to noisy operation and uneven temperatures.
When we replace a system, we look at the whole picture. We inspect your electrical service to ensure it can handle the new load, especially if you are considering a transition to a heat pump. My goal is to leave you with a system that works quietly and reliably, not just one that turns on and off.
How We Assess Your System
Before I ever recommend a replacement, I perform a full system assessment. This includes checking your current refrigerant levels, inspecting the heat exchanger for safety, and verifying the airflow at your registers. We don't guess; we measure.
Crucially, we perform a Manual J load calculation for every replacement. This is the industry standard for determining exactly how much heating and cooling your specific home needs based on your insulation, window orientation, and local climate. This ensures you aren't paying for a system that is too large, which causes short-cycling and humidity issues.
Repair or Replace: An Honest Look
The decision to replace an HVAC system is a big one. If your system is 12 years old and needs a minor repair, we will fix it. However, if your compressor is failing or your furnace heat exchanger is cracked, the repair costs often approach the value of the equipment. In those cases, I will show you the math.
We also look at the 'hidden' costs of keeping an old system: higher utility bills, the risk of a breakdown during a heatwave, and the lack of modern features like variable-speed motors. If you plan to stay in your home for several more years, a new, high-efficiency system usually pays for itself through energy savings and improved comfort.
Understanding Costs and Incentives
A complete HVAC replacement in a typical home runs between $7,500 and $14,000, depending on the equipment size and the complexity of the installation. I provide a written estimate that covers everything—no surprises. We also help you navigate the available rebates, such as the TECH Clean California program and federal tax credits for heat pumps.
These incentives can significantly lower your out-of-pocket cost. We handle the documentation for these programs so you don't have to worry about the paperwork. My focus is on making sure you get the best value for your investment, not just the lowest sticker price.
Safety First: Gas and Electrical
Safety is the most important part of my job. With gas furnaces, we check for carbon monoxide leaks and ensure proper venting. If we install a new heat pump, we ensure your electrical panel is up to the task. We never cut corners on safety, and we always pull the necessary permits for our work.
When you hire LC Heating & Air, you are getting a licensed C-20 contractor. We follow all local codes, which protects your home and your warranty. A system installed to code is a system that lasts.
Mistakes We See (And How We Avoid Them)
The most common mistake I see is 'oversizing.' People think a bigger unit is better, but a unit that is too big will cool your house too quickly without removing humidity, leaving you feeling clammy. We use Manual J calculations to prevent this.
Another mistake is ignoring the ductwork. If your ducts are leaky or poorly designed, even the most expensive AC unit will struggle to keep you comfortable. We inspect your ducts as part of the replacement process and address any issues that would prevent your new system from performing at its best.
Scheduling Your Replacement
Most full system replacements in Agoura Hills take one day—usually 6 to 10 hours. If we need to modify ductwork or handle complex electrical upgrades, it might take two days. We will give you a clear timeline in your proposal so you know exactly what to expect.
We respect your time and your property. We arrive when we say we will, keep the work area clean, and make sure you understand how to operate your new thermostat before we leave. If you have questions, I am always available to answer them.
Is it Time for a Change?
If you are constantly calling for repairs, or if your energy bills are climbing every year, it is time to have a conversation. I don't want you to spend money you don't have to, but I also don't want you to be stuck with a system that isn't doing its job.
Give me a call at (323) 970-3113. We can talk about your specific comfort issues and schedule a time for me to come out and take a look at your equipment. I will give you an honest assessment and a written estimate that makes sense.

What Agoura Hills customers say about hvac replacement
Verified reviews from homeowners in Agoura Hills and nearby neighborhoods who used our hvac replacement service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“Called on a Saturday because AC was blowing warm air. LC answered, sent someone the same afternoon. They found and fixed a refrigerant leak. Professional and reasonably priced.”
“Woke up to no AC at 6am. LC was at my door by 9am. Frozen evaporator coil — they explained exactly why it happened (dirty filter + low airflow) and fixed it same visit. Very professional.”
