Get your free estimateFast, Reliable AC Installation Across West Hills
AC installation in West Hills typically runs between $3,500 and $7,500 for a complete system, and we can usually have your new unit sized, quoted, and scheduled within a few days. Most West Hills homes we visit were built between the 1960s and 1980s, which means we’re almost never doing a simple swap. We’re checking ductwork, electrical panels, and rooflines before recommending anything, because a like-for-like replacement on an older home often just repeats the same cooling problems. If your AC gave out in the middle of a 100-degree stretch, call us at (559) 245-8195. We answer live, day or night, and we’ll give you a written price before any work starts.
Why Halden Heating and Air Woodland Hills Is West Hills’s Preferred AC Installation Company
Andre Fuller and our crew know West Hills streets by name, not just by GPS. When a call comes in from a home off Valley Circle Boulevard or a hillside property near Knapp Ranch Park, we already know what we’re likely to find: aging rooftop units, original ductwork, and electrical panels that were never sized for modern cooling loads. That local familiarity means faster diagnoses and fewer surprises on install day.
We don’t do four-hour windows. Every customer gets a live arrival time and can track their technician to the door, the same way you’d track a rideshare. You’ll know who’s coming, when they’ll arrive, and what the job costs before a single tool comes off the truck. Our AC Installation team sends you a written quote first, every time. No door-step price changes, no upsell pressure.
Every install is backed by our 365-Day Done Right Promise. If something isn’t right within a full year, we come back and make it right. That’s a written guarantee, included automatically, not an add-on you have to negotiate for. It’s part of The Relay Visibility Guarantee, and it’s the standard we hold every job to.

Central Air Conditioning Installation in West Hills
Central Air Conditioning Installation in West Hills is rarely a clean swap, because the homes here were mostly built when 2-ton units and minimal insulation were considered adequate. Today, with summer temperatures regularly topping 100°F and Santa Ana winds pushing dry heat through every gap, those original systems are often undersized by a full ton or more. What we typically do is start with a load calculation, then decide whether the existing ducts can handle the airflow a properly sized unit needs.
A full central air installation in West Hills runs $3,500 to $7,500, and the specific number depends on system size, efficiency rating, and whether we need to modify existing ductwork or upgrade an electrical panel. We’ll show you the price in writing before anything is ordered.
Ductwork Reality Check
Many West Hills homes still run on the ductwork installed in the 1970s. That means undersized returns, leaky joints, and high static pressure. When you put a new high-efficiency unit on old ducts, you often get noisy airflow and bedrooms that still won’t cool. We inspect and test before we quote, and sometimes the smarter investment is fixing the ducts alongside the unit.
Rooftop Unit Replacements
Homes along the northern edge near Knapp Ranch Park commonly have rooftop package units, and those fail differently than the split systems you’ll find elsewhere in the Valley. Heat, direct sun exposure, and age all take a toll. We replace them with properly sized SEER2 units and new curb adapters when needed, and we always check the roofline and drainage before recommending a specific model.
Furnace Installation in West Hills
Furnace Installation in West Hills doesn’t get the same urgency as air conditioning, but the winter nights here still dip cold enough to matter, especially in hillside homes with minimal wall insulation. If your furnace is original to a 1970s tract home, it’s likely running at 70% efficiency or worse, which means you’re paying to heat air that leaks right out of the flue. A new furnace installation in West Hills runs $3,500 to $7,500, depending on fuel type, efficiency, and whether we’re pairing it with a new coil or heat pump.
High-Efficiency Furnace Upgrades
When we replace an old furnace, we usually recommend moving to a 90%+ AFUE condensing unit if your setup allows for it. That means less gas consumed and a noticeable drop in your winter bill. We’ll explain the venting and drainage requirements in plain English so you know exactly what the job involves before you commit.
Dual-Fuel and Heat Pump Pairings
Some West Hills homeowners ask us to pair a new furnace with a heat pump, giving them efficient cooling in summer and efficient heating on mild winter days. It’s a smart move in this climate, where you need serious cooling for six months and only occasional heating the rest of the year. We’ll walk you through the rebate paperwork too.
Trusted Brands We Service in West Hills
We’re certified to install and service major equipment brands including Carrier, Trane, Lennox, and Goodman. When we recommend a brand for your West Hills home, it’s because the equipment matches your cooling load, your ductwork, and your budget, not because we have inventory to move. We keep common parts and components accessible for faster installs, so your new Carrier or Lennox system doesn’t sit waiting on a backordered part for two weeks. If you have a brand preference or an existing system you’d like to stay compatible with, tell us during the quote process and we’ll design around it.
Common AC Installation Problems We See in West Hills Homes
- Undersized original ductwork with high static pressure. This causes airflow noise and leaves bedrooms farthest from the air handler warm and stuffy. We measure static pressure during our load assessment so we know whether the ducts can support a new unit before we quote one.
- Original 100-amp electrical panels that can’t support a modern condenser. High-efficiency units draw less running power, but starting current can trip old breakers. We’ll check your panel load and let you know if an upgrade or subpanel is required before installation day.
- Single-zone systems on two-story 1960s floorplans. Upstairs rooms can run eight to ten degrees hotter than downstairs, which leads homeowners to rush into a bigger unit that never fixes the imbalance. A properly sized unit with zoning or damper adjustments usually solves what a bigger compressor can’t.
- Rooftop package unit failures near Knapp Ranch Park. These units sit in direct sun all day, and the first sustained heatwave of summer routinely exposes weak compressors and failing capacitors. We see the pattern every year and we stock what’s needed to replace them quickly.

FAQs About AC Installation in West Hills
Most West Hills homes were built with ductwork sized for much smaller cooling loads than today’s systems produce, and decades of leaks and settling have made the problem worse. High static pressure from undersized ducts causes noise and uneven cooling, especially in bedrooms at the end of long duct runs. We test and measure before recommending replacement, and often the right fix is sealing and resizing sections of existing ductwork rather than replacing every run. Call us at (559) 245-8195 for an assessment.
For most West Hills homes, yes. The climate here is cooling-dominant, with long hot summers and mild winter heating demand, which is exactly what heat pumps do well. A cold-climate heat pump can handle the occasional 35-degree night without backup heat, and you’ll likely qualify for utility rebates. We’ll run the numbers on your specific home and show you the payback before you decide.
If your panel is still the original 100-amp unit from the 1970s or 1980s, a new high-efficiency condenser may trip breakers during startup even if it uses less running power. We check panel capacity and existing loads during our quote visit, and we’ll tell you in writing whether a panel upgrade or a dedicated subpanel is required, what it costs, and whether we can handle it as part of the install.
Capacitor failures are common in West Hills because of sustained heat, and they often present as a system that hums but won’t start. If your unit fails right before a planned replacement, a capacitor repair may get you through the heatwave while you finalize your install decision. It won’t add days to your installation timeline, and we can often do the repair and the replacement assessment in the same visit.
The likely answer is that your system is still a single zone, and a single thermostat on the first floor can’t tell the unit what’s happening upstairs. Two-story 1960s floorplans in West Hills routinely run eight to ten degrees hotter upstairs, and a bigger unit won’t fix that. Zoning dampers, or a separate mini-split for the upper level, are the fixes that actually work. We’ll explain both options and their costs during your free estimate.
