Westlake Village is built around a man-made lake that sits across the Los Angeles and Ventura County line, though the incorporated city itself covers only the Los Angeles County third of the community around it. Whether it's a lakeside home or one of the corporate offices along the 101 corridor, you need an HVAC contractor who answers the phone, diagnoses the real problem, and gets things running again the same day.
The lake at the center of Westlake Village is entirely man-made, built in the 1960s as the centerpiece of one of the first master-planned communities in the Conejo Valley, and that lake, plus the corporate campuses that grew up around it, shape the HVAC work we do here.
Homes closest to the water deal with noticeably higher ambient humidity than the rest of the Conejo Valley, since the lake sits right there evaporating moisture into the air a condenser has to dump heat into, and that extra moisture accelerates corrosion on outdoor coils faster than it does a few streets back from the shoreline. On the commercial side, this is genuine headquarters territory: Dole Food Company, K-Swiss, and J.D. Power all have offices here, and buildings like that run on rooftop package units and zoned systems on a completely different maintenance schedule than a single-family home. We size and service both, honestly and without guessing.
CSLB #959168, based in Canoga Park, minutes from every Westlake Village neighborhood. No call centers, no subcontractors.
Lakefront home or corporate campus, we don't make you wait. Most repair calls in the 91361 area are seen the same day they come in.
Written estimates before any work starts, no upsell pressure, and TOP CLUB members save 15 to 25 percent on repairs.
From lakefront homes to the corporate campuses along Westlake Boulevard, Westlake Village property owners call us for the full range of heating and cooling work. Whether your AC quit in the middle of an August afternoon, your furnace is short-cycling on a cool morning, or you are planning a full system upgrade, 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 Westlake Village's foothill heat, from weak airflow and warm air to full no-cool breakdowns during a heat wave.
Know more →Right-sized, energy-efficient cooling for lakefront homes, inland properties, and corporate offices alike, with a proper load calculation so you never overpay to over-cool.
Know more →Fast furnace and heater troubleshooting for cool, damp Westlake Village winter mornings, so a system that only runs a few months a year works when you finally need it.
Know more →Energy-efficient heat pumps that handle both hot Westlake Village summers and chilly foothill nights from one system, often with rebate and financing options.
Know more →No two Westlake Village properties cool the same way. A home near the lake dealing with extra ambient humidity has very different needs than a corporate office running a rooftop package unit on a fixed schedule, and a single-family home a few streets back from the water is different again. We install and service the systems that actually fit this city, and we tell you honestly which one makes sense for your property and budget rather than pushing the most expensive option.
Ideal for additions and guest units where extending existing ducting isn't practical.
Know more →The lake that gives this city its name is entirely man-made, and it does more than sit there looking good. Homes and businesses close to the water deal with noticeably higher ambient humidity than the rest of the Conejo Valley, since a body of water that size is constantly evaporating into the surrounding air. That extra moisture makes an AC system work harder to dehumidify the same space and accelerates corrosion on outdoor coils and cabinets faster than it happens a few streets back from the shoreline.
The corporate campuses that grew up around the lake add a second, very different kind of demand. Buildings that house companies like Dole Food Company, K-Swiss, and J.D. Power run on rooftop package units and zoned commercial systems that need scheduled maintenance on a completely different rhythm than a home HVAC system. Winters here are mild, often dropping into the mid-40s at night, so a heating system that only runs a few months a year still needs to work correctly the first time it is called on.
Ambient moisture off the lake adds dehumidification load and accelerates coil corrosion nearby.
Rooftop package units on offices here run a very different maintenance schedule than homes.
Nighttime lows in the 40s mean heating systems need to perform on demand.
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. Our furnace kept cutting out and Ethan was very helpful and responsive on the phone. He sent Frank out and Frank was fantastic.

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.
