We install and replace Lennox air conditioning systems in Woodland Hills for $3,500 – $7,500, with most full-system jobs completed in one to two days from the time we confirm the equipment. That’s a straight number before we touch anything: no door-step price changes, no vague “we’ll see what we find” games. If you own a Lennox unit that’s failed, or you’re replacing an aging system with a new Lennox, you’re in the right place. Call (559) 245-8195 and you’ll get a real person, a written price, and an install date on the calendar.
This page is for Woodland Hills homeowners with Lennox equipment who want the real story on installation costs, what makes Lennox systems behave the way they do, and what an honest install actually involves. We’re an independent Lennox service provider, so what you’ll read here is what we see in the field, not a manufacturer brochure.
How Lennox Products Fail – and How We Fix Them
- Lennox XC/XP Series compressor failures from capacitor strain. The XC14 and XC16 lines are solid machines, but the factory capacitors run under constant thermal stress in Woodland Hills summers, where attic temperatures hit 140°F and rooftop condensers bake in direct sun from noon to seven. When a capacitor begins to fail, the compressor pulls higher amperage and eventually locks up. During an ac installation, we replace the capacitor as standard on these systems rather than reinstalling the old one, and we size the replacement to the unit’s actual run conditions, not just the spec sheet.
- Lennox Signature Series (SL18/XC20) variable-speed boards that don’t get along with older thermostats. These are inverter-driven systems that want a communicating thermostat, yet we regularly pull them out of homes where someone paired them with a basic digital stat from a big-box store. The system then runs at full bore constantly, the compressor short-cycles, and the owner’s electric bill in Woodland Hills goes through the roof. When we install these units, we confirm the thermostat compatibility before we ever order equipment, and we include the correct communicating control in the quote so there’s no add-on later.
- Lennox evaporator coil corrosion on the EL Series (ML14/EL16). Fox and thermoduric acids from decomposing leaves don’t cause this, but the mild marine layer that rolls up through the Santa Monica Mountains does: salt-laced fog air that settles on copper-aluminum coils accelerates corrosion in outdoor units near the south and west edges of Woodland Hills. We see pinhole leaks on five-year-old coils that should have lasted twelve. During an ac installation we’ll assess whether the coil needs full replacement, and when it does we’ll tell you what the OEM coil costs versus a quality aftermarket option and how each affects your Lennox warranty.
- Lennox Merit Series air handlers in closets with zero clearance. Many Woodland Hills condos and townhomes have the air handler tucked into a hallway closet with maybe four inches of clearance on the side panels. Lennox Merit units (ML14 air handlers especially) start making a low thrumming sound as blower bearings wear. We see it on units less than six years old. During installation, we’ll reposition or rebuild the filter access if needed so the new unit gets proper airflow and you don’t end up with the same problem.
- Refrigerant line set failures on split systems in hillside homes. In the areas up near Warner Center and along Valley Circle, some homes have line sets running twenty-five-plus feet through attic walls and down exterior chases. We’ve pulled apart copper lines where UV degradation at the insulation wrap caused the insulation to crumble and the copper to develop hairline cracks. When we do a Lennox installation in these homes, we pressure-test the existing line set before reusing it; if it’s compromised, we run a new one. The cost is included in the quote up front, not discovered after the old unit is on the truck.

Our Lennox AC Installation Process
- 1
Book online or call. You’ll get a live arrival time you can track to your door, not a four-hour window.
- 2
We walk the job with you. We check the existing condenser, air handler, line set, duct connections, and electrical. We look at the specific model you’ve got now and whether it’s sized right for your square footage. Andre Fuller has seen too many Woodland Hills homes with a 5-ton condenser slapped onto ductwork sized for 3.5 tons.
- 3
Written price before any work starts. The quote includes equipment, line set work if needed, electrical if needed, thermostat, and any condensation line adjustments. It’s one number. It doesn’t change at the door.
- 4
Install day. We remove the old system, inspect the existing line set and electrical, and run everything past you in plain English. OEM parts stay OEM where it matters for your warranty; we’ll tell you when a quality aftermarket part makes better sense and why.
- 5
Startup and test. We run the new Lennox system through a full startup, measure refrigerant pressures and subcooling, verify airflow at the supply registers, and confirm the thermostat is controlling the system correctly.
- 6
Cleanup and guarantee. We show you photos of the finished work, walk you through the new system’s operation, and you get the 365-Day Done Right Promise in writing. If it’s not done right, we make it right.

AfterWhat Lennox AC Installation Costs in Woodland Hills
Full Lennox ac installation in Woodland Hills typically lands between $3,500 and $7,500. Here’s what that looks like in the real world:
- Merit Series (ML14) 3-ton full system: $3,500 – $4,500
- Elite Series (EL16/EL18) 3.5 – 4-ton full system: $4,500 – $6,000
- Signature Series (XC20/SL28) high-efficiency variable-speed system: $6,000 – $7,500
What moves the price: whether the existing line set is reusable, whether your electrical panel needs a breaker upgrade, whether the ductwork needs modification, and whether you’re going from a single-speed to a variable-speed unit that needs a matching thermostat. All of it goes into the written quote before work starts. We give free estimates, so call (559) 245-8195 and we’ll give you an exact number.

FAQs
No. Lennox warranties cover equipment failures, not who installs it. As an independent Lennox service provider, we follow factory installation guidelines and document the install so your warranty stays intact. We’ll give you clear guidance on which parts stay OEM and which won’t affect your warranty either way.
Most Lennox ac installations are completed within one to two days of confirming equipment availability. If you’re replacing an existing system, we can give you a written quote on the first visit and schedule the install date before we leave. Call (559) 245-8195 to get things moving today.
If your Lennox system is under ten years old and the repair is under $650, repair usually makes sense. If the compressor is gone, the coil has multiple leaks, or the unit is over twelve years old, replacement is almost always the smarter money, because a new system will have a fresh warranty and significantly better efficiency. We’ll give you the repair cost, the replacement cost, and let you make the call with both numbers in front of you.
Yes, where it matters for warranty and performance. For critical components like the compressor, coil, and control board, we use genuine Lennox OEM parts. For supporting components like capacitors, contactors, and condensate traps, we often use quality aftermarket equivalents that perform identically and cost less. We’ll tell you what’s what before we order anything.
Yes. We install Lennox heat pumps and Lennox mini-split systems in addition to central air systems. Heat pumps make particular sense for Woodland Hills homes with no existing gas furnace, and many homeowners in the hillside areas choose mini-splits for room-by-room control. We’ll walk you through the options and the cost differences during your free estimate.
