Granada Hills HVAC Contractor: What We Cover

Stay Cool Air Conditioning & Heating, Inc is a licensed HVAC contractor serving Granada Hills, CA, handling repairs, maintenance, and new installations for homeowners across the western San Fernando Valley. When your air conditioner stops keeping up on a sweltering Granada Hills afternoon, the problem rarely fixes itself, and waiting only makes the heat inside worse. Stay Cool brings over 20 years of hands-on HVAC experience to Granada Hills homeowners who need reliable repairs, thorough HVAC maintenance, and properly sized new installations. Every job is completed under CA license #1036487, and you can reach owner David Medina directly at (888) 960-6003.

Granada Hills sits in the western San Fernando Valley, where summer temperatures routinely climb past 100°F and outdoor units work around the clock to keep interiors comfortable. The design temperatures here tell the story plainly: 97°F in summer, 40°F in winter. That kind of sustained load accelerates component wear, and systems that were running fine in April can struggle or fail by July. Much of the Granada Hills housing stock consists of ranch-style homes built between the late 1950s and early 1970s, meaning original ductwork that's now 55 to 70 years old is a common finding on service calls. Permits for any AC or furnace replacement go through the City of Los Angeles Department of Building and Safety (LADBS), and Stay Cool handles that process with every qualifying installation. SoCalGas offers rebates on qualifying high-efficiency furnaces when installed by a licensed contractor with a closed permit, which is worth factoring into a replacement decision.

Full-Scope Service

HVAC Services Granada Hills Homeowners Depend On

One contractor covers every system in your home, from the condenser on the pad to the vents in the ceiling.

AC Repair and Maintenance

Refrigerant recharges, compressor diagnostics, capacitor and contactor replacements, and pre-season air conditioner maintenance tune-ups. If your system is struggling in July, the fix is faster when it's been serviced in April.

Furnace Installation and Repair

Granada Hills winters are mild but real, and a furnace that hasn't been inspected in a few years is a furnace that fails on the coldest night. We handle repairs and furnace replacements, including permit coordination with LADBS.

Mini Splits and Heat Pumps

Ductless mini splits are a practical answer for garage conversions, room additions, and older homes where running new duct is not worth the cost. Heat pump installation gives you heating and cooling in one system, well-matched to Granada Hills's mild winters.

Indoor Air Quality

Hot, dry Valley summers concentrate dust and allergens indoors. We install high-efficiency air cleaners and whole-house air treatment systems that address filtration, not just airflow. We'll tell you what your home actually needs.

Duct Repair and Sealing

Homes from the 1960s and 1970s often have original flex duct that's collapsed, disconnected, or leaking conditioned air into the attic. A duct inspection is the first thing to check when rooms aren't cooling evenly.

Dryer Vent Cleaning

A clogged dryer vent is a fire risk. It's also the reason your dryer runs two or three cycles to finish a load. We clean and clear residential dryer vents on the same visit when time allows.

Why Granada Hills Homeowners Trust Stay Cool

Choosing an HVAC contractor in Granada Hills means finding someone who understands local conditions and shows up when they say they will. Stay Cool is a family-owned operation where accountability is personal: you're calling David's number, and David's name is on the license. That's different from a dispatch center routing a stranger to your door. We don't subcontract. We won't recommend a full replacement when a repair is the right call. And we're straight with you on what your older home's duct system actually needs, because a 1965 ranch in Granada Hills isn't the same job as a 2010 tract home in another part of the Valley. Our HVAC service covers the full range, and our assessments don't come with pressure to buy more than the situation requires.

Granada Hills HVAC Questions, Answered

What HVAC system type works best for a Granada Hills home?
Most Granada Hills homes were built in the 1960s and 1970s with central forced-air systems, and a properly sized central AC and furnace combination is still the right answer for most of them. If you're adding a room, converting a garage, or dealing with a space that's hard to condition through existing ducts, a ductless mini split is worth considering. Heat pumps are a good fit for Granada Hills's climate because they handle both heating and cooling efficiently, and the winters here are rarely cold enough to push a heat pump into backup heating mode.
How do I know whether to repair or replace my air conditioner in Granada Hills?
The honest answer depends on the age of the system, the cost of the repair, and how efficiently it's been running. A system that's 12 to 15 years old and needs a compressor or coil replacement is usually a candidate for replacement, because the remaining life on the equipment doesn't justify the repair cost. A system that's 7 years old with a failed capacitor is a repair. We'll give you a straight read on where your system falls. See our guide to telling when AC needs replacement for more detail.
Does HVAC work in Granada Hills require a permit?
Yes. Replacing an air conditioner or furnace in Granada Hills requires a permit through the City of Los Angeles Department of Building and Safety (LADBS), and a city inspection closes the permit after the work is done. We handle permit coordination on qualifying installations. Any contractor who skips the permit is leaving you exposed on resale and insurance.
Why is indoor air quality a concern for Granada Hills homes specifically?
The San Fernando Valley's hot, dry summers push people to keep windows closed and recirculate indoor air for weeks at a time. Without adequate filtration, that air accumulates dust, allergens, and particulates at higher concentrations than you'd find in a home that gets regular fresh-air exchange. Granada Hills tap water also carries a lower quality score than many Valley communities, which is worth knowing for humidification equipment. A whole-house air treatment system or high-efficiency filtration upgrade addresses the recirculation problem directly.
What does an HVAC maintenance visit in Granada Hills include?
A standard HVAC maintenance visit covers refrigerant pressure check, airflow measurement, burner cleaning and adjustment on gas furnaces, heat exchanger inspection, capacitor and contactor testing, thermostat calibration, and filter check. On older Granada Hills homes we also look at the duct connections at the air handler, because original flex duct from the 1960s and 1970s deteriorates at the joints first. The benefits of an annual maintenance plan are real: a system that's been serviced regularly is less likely to fail during a July heat wave.
How often should I replace the air filter in my Granada Hills home?
Every 30 to 90 days, depending on the filter type, the number of people in the home, and whether you have pets. In Granada Hills, the dry summer months push more airborne dust through the system, so checking the filter every 30 days during peak cooling season is a reasonable habit. A clogged filter forces the system to work harder and can cause the evaporator coil to ice over, which looks like the system stopped cooling but is actually a restricted-airflow problem.
Are SoCalGas rebates available for furnace replacement in Granada Hills?
SoCalGas does offer rebates on qualifying high-efficiency natural gas furnaces. The rebate requires installation by a licensed contractor and a closed permit from LADBS, so skipping the permit process costs you the rebate in addition to the other risks. We can tell you whether the system you're replacing qualifies and what documentation the rebate submission requires. Contact Stay Cool at (888) 960-6003 to discuss your options.

What are common HVAC problems in older Granada Hills homes?
The most common issues we see in Granada Hills's 1960s and 1970s housing stock are deteriorating flex duct that leaks conditioned air into the attic, aging capacitors and contactors that fail during peak summer load, and refrigerant systems that haven't been serviced in years. Undersized systems are also common, because original equipment was sized for a home without added square footage, patio enclosures, or higher internal heat loads.

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 😊.
