Woodland Hills holds the record for the hottest official temperature ever measured in Los Angeles County, and a Warner Center office tower needs its rooftop units running just as reliably as a home off Ventura Boulevard needs its AC. You need an HVAC contractor who answers the phone, diagnoses the real problem, and gets you comfortable again the same day.
On September 6, 2020, the official National Weather Service station at Pierce College recorded 121 degrees, the hottest temperature ever measured at any weather station in Los Angeles, Ventura, Santa Barbara, or San Luis Obispo County. That single number tells you most of what you need to know about sizing an HVAC system here.
Woodland Hills started in 1922 as a real estate promotion called Girard, named after its developer, complete with fake storefronts and a mosque tower built to make the empty land look like a thriving town. Residents renamed it Woodland Hills in 1941, and by the following decade Warner Bros. co-founder Harry Warner had assembled a 1,100-plus acre horse ranch nearby that doubled as a backlot for Western TV shows like Maverick and Cheyenne. When the Warner family sold off the land in the 1980s, it became Warner Center, now one of the largest business districts in the San Fernando Valley, with office towers, Topanga Plaza, and Pierce College anchoring the area around Topanga Canyon Boulevard and Victory Boulevard.
That history left Woodland Hills with two very different HVAC realities living side by side. Residential neighborhoods stretch from flatter tracts near Ventura Boulevard to hillside homes climbing toward the Santa Monica Mountains, each with different insulation, orientation, and cooling needs. Warner Center itself is something else entirely: dense, multi-story commercial buildings that need reliable, professionally maintained rooftop HVAC units running through the same triple-digit stretches that make the residential side of town call for service. We size and service both, and we do not treat a Warner Center suite the same way we treat a single-family home.

From single-family homes off Ventura Boulevard to office suites inside Warner Center, Woodland Hills property owners call us for the full range of heating and cooling work. Whether your AC quit during a record-setting heat wave, your furnace is struggling on a cold winter morning, or you are planning a full system upgrade before summer hits, our licensed technicians handle it. Every visit starts with a real diagnosis, not a guess, and every quote is written down before any work begins.
Same-day diagnosis for AC units struggling through Woodland Hills's record-setting heat, from weak airflow and warm air to full no-cool breakdowns.
Know more →Right-sized, energy-efficient cooling for both hillside homes and flatter Ventura Boulevard-area properties, with a proper load calculation for extreme heat.
Know more →Fast furnace troubleshooting for Woodland Hills's genuinely cold winter mornings, since a system that only runs part of the year needs to work when called on.
Know more →Energy-efficient heat pumps that handle both record-breaking summer heat and genuinely cold nights from one system, often with rebate and financing options.
Know more →No two Woodland Hills properties cool the same way. A single-family home off Ventura Boulevard has very different needs than a hillside property near the Santa Monica Mountains, and a multi-story office suite inside Warner Center is an entirely different job from either one. We install and service the systems that actually fit the property, and we tell you honestly which one makes sense rather than pushing the most expensive option.
The standard for most Woodland Hills single-family homes with existing ductwork.
Know more →Ideal for additions, guest units, and individual office suites near Warner Center.
Know more →One system for both record-setting summer heat and genuinely cold winter nights.
Know more →Reliable heating for the coldest Woodland Hills mornings, which run genuinely colder than most of the Valley.
Know more →Woodland Hills does not just run hot, it holds the official record. On September 6, 2020, during a historic Labor Day heat wave, the National Weather Service station at Pierce College recorded 121 degrees, the highest temperature ever measured at any official weather station in Los Angeles County, breaking the previous record of 119 set in 2006. That reading also topped every station in Ventura, Santa Barbara, and San Luis Obispo counties. AC systems here are not being asked to handle an unusually hot day now and then. They are being asked to survive conditions that made regional history, and undersized or aging equipment shows it first.
The same station also holds the area's record low of 18 degrees, set in February 1989, and Woodland Hills routinely sees some of the widest day-to-night and season-to-season temperature swings anywhere in the San Fernando Valley. That means a system here has to perform at both extremes, not just cool well on the hottest day of the year. Heat waves severe enough to trigger statewide Flex Alerts and rolling blackout warnings, as happened during the 2020 record, put extra strain on equipment and the power grid at the exact moment homeowners need cooling most, which is why we size conservatively and build in the headroom other cities do not need.
The 121°F reading at Pierce College is the hottest ever recorded in LA County, pushing AC systems to their limit.
The same weather station holds an 18°F record low, meaning systems must perform at both extremes.
Dense office towers need rooftop units maintained on a professional schedule, not a residential one.
We diagnose the actual issue on site and hand you a written estimate before anything starts.
We size the system to your home and schedule the work around your timeline, not ours.
Our crew cleans up after every job and walks you through the new system before we leave.

EXCELLENT Based on 121 reviews Posted on יניב אליאסTrustindex verifies that the original source of the review is Google. Our old AC was constantly causing issues, so we decided to replace it. After getting five estimates, we chose Top AC — and we’re very happy we did. Ethen was professional, honest, and great to work with. The price was fair and right in the middle of the market. The team arrived on time, did a clean and proper installation, and coordinated smoothly with our roofing company during our roof replacement. Highly recommend Top AC — reliable, professional, and excellent service.Posted on Orit RavidTrustindex verifies that the original source of the review is Google. Can’t recommend TOP AC enough! My heater stopped working and they showed up the same day I called, diagnosed the issue quickly, and had it fixed right away. Super professional, honest, and the price was very fair. Such a relief to work with a company that’s reliable and efficient. I’ll definitely be using them again.Posted on Gary BatchleyTrustindex verifies that the original source of the review is Google.

Thank you, Adi 😊😊😊Posted on Jonathan BrayTrustindex verifies that the original source of the review is Google. Great experience with these guys.

EXCELLENT Based on 223 reviews Posted on Tae Jung K.Verified Problem: AC is running but no air is coming out. Quality: Inspected every single details with care . It was a clogged filter that needs to be replaced. Thanks to Frank. Value: It took less than hour to fix the issue. Great value. No hidden fee.Posted on Alison C.Verified Great experience with Top AC. Ethan was responsive and easy to connect with to schedule a tech for routine maintenance. Frank was the technician and he was polite, informative about what he was seeing, communicative, and friendly. This company is trustworthy and I've already recommended to my neighbors. Prices are very fair and I've really glad I've come across this company as I will continue to utilize them for my HVAC service and future needs. Thank you!Posted on Johnny A.Verified Our old AC was constantly causing issues, so we decided to replace it. After getting five estimates, we chose Top AC ,and we're very happy we did. Ethen was professional, honest, and great to work with. The price was fair and right in the middle of the market. The team arrived on time, did a clean and proper installation, and coordinated smoothly with our roofing company during our roof replacement. Highly recommend Top AC reliable, professional, and excellent service.Posted on Lee D.Verified Top AC is incredibly honest and trustworthy. I needed an urgent repair and even though they couldn't fit me in right away, they recommended I get a quote and inspection from another company so I could get help ASAP. That company quoted me $1,200. A few days later, Top AC came out, diagnosed the real issue as a small part (not what the other company claimed), and fixed it in an hour for $375. Itay is super helpful and trustworthy, and Frank is excellent at what he does. I won't use any other HVAC company.Posted on Gabby O.Verified I don't even know where to begin about how much I love this company. We have a nice house, but that doesn't mean I have any extra money. Our furnace went out and I called the company that had installed (but they always seem to charge me a lot) to come out and check it. The technician came up and calmly told me it was some sort of switch that needed to be replaced and the estimate would be $1265. I don't have $1265 but I was just curious how much the parts were so I looked it up. The parts themselves come to $16. A friend of mine recommended Adi & Top AC Heating and Air-conditioning, so I called them for a second opinion. Frank the technician came out, looked at it, pressed the reset button and it was fixed. It took him all of five minutes and all I was only charged was the diagnostic fee. Plus, he showed me how to press the button myself next time should it happen again! I can't believe another company was willing to take $1300 from me for NOTHING. Be careful of who you trust, but I can tell you that you can trust Top AC fully!!!!Posted on Donna T.Verified The first time I called, Top AC sent someone to repair my father's AC. Everything went smoothly. The second time I called this company, the problem was my father's heater. After speaking with Adi about the problem, he sent Frank to take a look at the problem. The problem was a simple fix, but Frank noticed that the pipe for the gas was loose. He recommended that I call my plumber to fix it. Overall, I appreciate this company's honesty and availability.Posted on Trent C.Verified Extremely polite and diligent. Got back to me in record time, putting this highly anxious first time home owner at ease. High marksPosted on Jamie S.Verified Our AC broke down on a Saturday. Isaac was fast and came out within 90 minutes. Good experience.Posted on Fred F.Verified I made request for immediate assistance with malfunctioning AC. Top AC sent Frank to my home in Burbank. He was very helpful and informative. It turned out that my rooftop unit, which he thoroughly inspected, was in good shape but there was an issue with my thermostat. Frank changed the program on the thermostat and it has been working fine since. I really appreciate good service when I see it. The fee was very reasonable.Posted on Eli S.Verified Great service! The specialists that came to do the work were amazing!! So glad we worked with them!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
