I’m Leo, owner of LC Heating & Air. I’ve spent enough time in attics and crawlspaces to know that most major HVAC breakdowns aren't sudden accidents—they are the result of small, ignored problems that finally hit a breaking point. In a place like Tarzana, where our summers regularly push temperatures toward 100 degrees, your AC system is working harder than almost any other appliance in your home.
My approach to maintenance is simple: I treat your equipment like it were my own. We don't use maintenance visits as a sales pitch for new equipment. Instead, we perform a detailed, 21-point inspection to ensure your system is safe, clean, and operating as efficiently as possible. If a repair is needed, we provide a written estimate before we touch a thing, and we’ll tell you honestly if the fix is worth the investment or if it’s time to start planning for a replacement.
Call LC Heating & Air at (323) 970-3113 for scheduling and estimates.

Preventative maintenance and honest repair diagnostics
Common HVAC Patterns in Tarzana
Tarzana’s housing stock, particularly the ranch-style homes from the 1960s and 70s, often features original ductwork that has reached the end of its lifespan. Over five decades, that ducting can develop leaks or collapse, forcing your blower motor to work twice as hard to move air. We see many homeowners struggling with uneven cooling because their aging duct systems can't keep up with modern insulation and renovation standards.
Additionally, the western Valley climate brings a lot of dust and pollen. When this settles on your evaporator coils, it acts like a blanket, trapping heat and preventing your system from cooling your home effectively. We frequently find that a simple, professional coil cleaning can restore the performance of a system that a homeowner thought was 'dying,' saving them the cost of a full replacement.
Renovations and Airflow Imbalances
We see a lot of home renovation activity in Tarzana, from expanded master suites to converted garages. The challenge here is that many of these additions were built onto existing HVAC systems that weren't sized for the extra square footage. This often leads to 'hot spots' in the house.
If you’ve added space to your home, your system might be struggling with a load imbalance. We look at these factors during our maintenance visits to see if your current setup is actually capable of handling the load, or if you might benefit from a supplemental solution like a mini-split system for those specific areas.
Our 21-Point Inspection Process
When we arrive at your home, we aren't just changing a filter. We follow a strict 21-point protocol. We check the electrical connections, which can vibrate loose over time, and test the capacitor—a small part that, if it fails, can lead to a much more expensive compressor burnout.
We also perform a combustion analysis on your furnace to ensure there are no carbon monoxide leaks. Safety is non-negotiable. By the time we finish, you’ll have a clear, written report of exactly what we found, how your system is performing, and what (if anything) needs attention.
The Honest Repair vs. Replace Decision
One of the most common questions I get is, 'Leo, should I fix this or just buy a new one?' My answer depends on the math and the condition of the equipment. If a system is relatively new and has a minor issue, a repair is almost always the right move.
However, if your system is 15+ years old and the repair cost is significant, I will tell you that you’re likely throwing good money after bad. We don't push for replacement unless it genuinely makes financial sense for you. We provide the facts, and you make the call.
Understanding Your Costs
We believe in transparent pricing. A standard maintenance tune-up ranges from $89 to $175, and a diagnostic visit is $125 to $200. If you need a full system replacement, those costs can range from $6,000 to $18,000+ depending on the size and efficiency of the unit required for your home.
We don't hide behind hidden fees. When we provide an estimate, that is the price. We also offer a maintenance agreement that includes priority scheduling and a 15% discount on parts, which many of our Tarzana neighbors find to be a great value for keeping their systems running year-round.
Scheduling and Access
We know your time is valuable. We offer same-day service options and prioritize our maintenance agreement customers. Because we are based nearby, we can get to your home in Tarzana quickly.
When we arrive, please ensure we have clear access to your attic or crawlspace and your outdoor condenser unit. If your unit is tucked away behind landscaping or in a tight attic, let us know when you book so we can bring the right equipment to get the job done safely.
Mistakes to Avoid
The biggest mistake I see is homeowners waiting until the first 100-degree day to find out their AC isn't working. By then, every HVAC tech in the Valley is booked solid. Another mistake is ignoring small sounds—a rattling or clicking noise is almost always a sign of a part that is about to fail.
Also, don't forget to change your filters. A clogged filter is the fastest way to kill a blower motor. Check them monthly, especially during wildfire season when air quality drops and dust levels rise.
Health and Safety First
Your HVAC system is responsible for the air you and your family breathe. Beyond just temperature, we check for proper ventilation and ensure that your gas furnace is venting combustion gases safely outside. We take CO testing seriously because it’s a silent danger that shouldn't be left to chance.
A clean system is a healthy system. By keeping your coils and blower clean, we help reduce the amount of dust and debris circulating through your home, which is a big deal for families dealing with allergies.
Is It Time for Maintenance?
If your system hasn't been serviced in over a year, or if you've noticed your electric bill creeping up without a change in your habits, it’s time for a tune-up. These aren't just 'check-the-box' visits; they are the best way to extend the life of your equipment and avoid the stress of a breakdown during a heatwave.
Call LC Heating & Air at (323) 970-3113. We’ll get you on the schedule, perform a thorough inspection, and give you an honest assessment of your system’s health. No pressure, no games—just professional service from a local contractor.

What Tarzana customers say about hvac maintenance
Verified reviews from homeowners in Tarzana and nearby neighborhoods who used our hvac maintenance service.
“LC is our go-to for everything HVAC. They've done two mini splits, a furnace replacement, and annual maintenance for our Tarzana home. Leo runs a tight ship — every tech is professional and they always show up on time.”
“Got quotes from four companies. LC was the only one that actually did a Manual J calculation and explained why our old system was oversized. The new properly-sized Trane system cools better, runs quieter, and costs less to operate.”
