HVAC Contractor Calabasas Homeowners Rely On

Stay Cool Air Conditioning and Heating is a licensed HVAC contractor serving Calabasas, CA, handling everything from air conditioner repair and furnace service to duct repair, mini splits, and whole-house air treatment. CA license #1036487. When something breaks in a Calabasas summer, you don't want a dispatcher routing a stranger to your door, you want someone who knows this area, picks up the phone, and shows up ready to work. Call (888) 960-6003 to schedule service.

Rather than calling a large impersonal service company, Calabasas homeowners who want reliable HVAC work done right the first time choose Stay Cool Air Conditioning & Heating, Inc. As a family-owned and operated contractor, we serve Calabasas with the kind of honest, thorough HVAC service that builds long-term relationships. Our licensed technicians handle everything from routine maintenance and seasonal tune-ups to complete system installations, all with a focus on quality that holds up well after the job is finished. Calabasas sits at the western edge of the San Fernando Valley where temperatures climb significantly in summer and where the shift between warm days and cool nights creates thermal cycling that can stress HVAC components over time. Refrigerant line connections and ductwork joints are particularly vulnerable to repeated expansion and contraction, making annual inspections a practical investment for homeowners who want to avoid unexpected failures.

  • Ductless mini-split systems, ideal for older homes without existing ductwork

Full HVAC Services for Calabasas Homes

One contractor handles every system, no subcontracting, no runaround.

Air Conditioner Repair & Installation

Whether your AC stopped cooling on a 95-degree afternoon or you're replacing a unit that's been limping along for years, we diagnose accurately and install correctly. New installations in Calabasas require a building permit from the city's building department, we know the process.

Furnace & Heat Pump Service

Calabasas homes built in the 1980s often have aging furnaces that haven't been touched in years. We repair, replace, and maintain furnaces and heat pumps, and we'll tell you honestly whether a repair makes sense or a replacement is the smarter move.

Mini-Split Systems

Many Calabasas homes don't have ductwork in every room, especially in additions and converted spaces. A ductless mini-split adds precise comfort without a full duct retrofit. We size them right for the room and install them cleanly.

Duct Repair & Sealing

Older ductwork in Calabasas homes leaks conditioned air into attics and crawl spaces, driving up energy bills and leaving certain rooms uncomfortable. We inspect, seal, and repair ducts, and replace sections that have deteriorated past the point of sealing.

Indoor Air Quality

Wildfire smoke is a real seasonal concern in this part of Los Angeles County. A whole-house air treatment system installed by Stay Cool filters particulates at the source rather than relying on a portable unit in one room. We also install high-efficiency air cleaners and MERV-rated filtration upgrades.

Dryer Vent Cleaning

A clogged dryer vent is a fire hazard, not just an inefficiency. We clear lint buildup from the full length of the vent duct and verify proper airflow at the exterior termination before we leave.

Calabasas Homes and the HVAC Issues They Bring

Most homes in Calabasas were built in the 1970s and 1980s. The systems inside are old enough to show it.

The median construction year for homes in Calabasas puts most of the housing stock at 35 to 50 years old. That means original ductwork that's brittle and leaking, furnaces that have outlived their expected service life, and AC systems running on refrigerants that are no longer manufactured. Thermal cycling is a real factor here: the gap between daytime highs and overnight lows causes refrigerant lines and duct joints to expand and contract repeatedly, loosening connections over time. Annual inspections catch those small failures before they become a midnight breakdown. The Las Virgenes Municipal Water District supplies Calabasas with moderately hard water, roughly 105 mg/L, which can affect components that come into contact with condensate over years of operation. It's not dramatic, but it's another reason to have a technician check coil and drain pan condition during a seasonal tune-up rather than skipping it.

Local Requirements

Permits and Inspections for Calabasas HVAC Work

Calabasas handles its own permitting. This is not an LADBS process.

City Building Permits Required

Most HVAC modifications and new installations in Calabasas require a building permit from the Calabasas building department. This is separate from the LA County or LADBS process. Separate trade permits for mechanical work are typically required alongside any electrical or plumbing permits the job touches.

Inspection Scheduling Timeline

Inspection requests must be submitted by 3:00 p.m. on the business day before the desired inspection date. We factor this into project scheduling so your system isn't sitting half-installed waiting on an inspection window nobody planned for.

Refrigerant Charge Verification

New AC installations in California require a verified refrigerant charge test per Title 24 standards. This isn't optional and it isn't bureaucratic paperwork, an improperly charged system runs inefficiently from day one and wears out faster. We test to spec.

SCE and SoCalGas Rebates for Calabasas Homeowners

Calabasas homeowners use Southern California Edison for electricity and SoCalGas for natural gas. Both utilities have offered rebate programs for high-efficiency HVAC equipment and electrification upgrades, including heat pumps, smart thermostats, and qualifying AC systems. Rebate availability and amounts change, so we won't quote a number here that may be out of date by the time you read it. What we can tell you is that if you're replacing an older furnace or aging AC unit, it's worth asking us about current qualifying equipment before you commit to a system. A thermostat installation on a qualifying smart thermostat has also been a rebate-eligible upgrade through SCE programs. Contact Stay Cool at (888) 960-6003 and we'll walk through what's currently available for your situation.

Calabasas HVAC Questions: Answered Directly

Does Calabasas require a permit for AC or furnace replacement, and how long does the process take?
Yes. Most HVAC installations and significant modifications in Calabasas require a building permit from the city's building department, along with a separate mechanical trade permit. Inspection requests must be submitted by 3:00 p.m. the business day before the desired date. We handle the permit coordination on our end so the project doesn't stall waiting on paperwork.
Why does a new AC installation in Calabasas require a refrigerant charge test?
California's Title 24 standards require a verified refrigerant charge test for new AC installations. The test confirms the system is charged to the manufacturer's specification. An undercharged or overcharged system runs harder than it should, uses more energy, and fails sooner. It's a required inspection step, not something we skip.

It's a required inspection step, not something we skip.
Can my HVAC system help filter wildfire smoke in Calabasas?
It can, with the right filtration. A standard 1-inch filter won't catch fine smoke particulates effectively. Upgrading to a MERV-rated pleated filter or installing a whole-house air treatment system gives your HVAC system the ability to pull smoke particles out of the air as it circulates through the home. We can assess your existing system and tell you what upgrade makes sense for your setup.
My Calabasas home was built in the 1980s. Should I replace the furnace or repair it?
A furnace from the early 1980s is at or past its expected service life, and parts availability gets thinner every year. If the heat exchanger is cracked, that's a safety issue that makes replacement the only responsible answer. If it's a control board or igniter, a repair can extend service life a few more years at reasonable cost. We'll give you a straight answer after we look at it, not a push toward the more expensive option.
What HVAC rebates are available through SCE and SoCalGas in Calabasas?
Southern California Edison and SoCalGas both run rebate programs for qualifying high-efficiency equipment, including heat pumps, smart thermostats, and certain AC systems. Rebate amounts and qualifying equipment change throughout the year, so we won't publish a figure here that may be outdated. Call us at (888) 960-6003 and we'll check current program availability for the equipment you're considering.
How do I know if my Calabasas home's ductwork needs repair or replacement?
Common signs are rooms that never reach the thermostat setting, unusually high energy bills, or visible separation at duct joints in the attic. Homes in Calabasas built in the 1970s and 1980s often have flex duct that has sagged or torn over time, losing a significant portion of conditioned air before it reaches the living space. We inspect the full duct system and tell you what can be sealed versus what needs to be replaced. See our duct repair service for more detail.
Is a heat pump a good option for a Calabasas home that currently has a gas furnace?
It depends on the home's existing infrastructure and how it was built. Calabasas has a hot-summer Mediterranean climate with mild winters, which is actually well-suited to heat pump efficiency, since extreme cold is rare. Older homes may need electrical panel upgrades to support a heat pump. We assess the existing system before recommending electrification, and we won't push a heat pump installation that the home's infrastructure can't support cleanly.

The owner David came over and installed the air conditioning and furnace in record time, 4 hours. This was during a heat wave. He and his crew were professional and courteous. They are a great family run business 😊.
