Furnace acting up in a newer home, or a zoned system that stopped heating one floor? TOP AC repairs, replaces and maintains heating systems across Big Sky, with same-day service and a written price before work starts.
Big Sky is one of the newest parts of Simi Valley, so its furnaces are not ancient, but many are now old enough that warranties have ended and the first real repairs are arriving.
Much of the neighborhood was built in the 2000s and 2010s on land that was once part of the Big Sky Ranch, the large Patterson and Getty era ranch property. Homes here tend to be roomy, tightly sealed two-story layouts with zoned forced-air systems, plus a number of hillside custom estates. TOP AC repairs, replaces and services heating across Big Sky using licensed technicians dispatched from our Simi Valley office.
Book Heating Service
Many newer homes were fitted with standard builder-grade furnaces. At 15 years or more, ignitors, blower motors and capacitors start to fail, and the original parts warranty has usually run out.
Larger two-story and custom homes here often use zoned forced air with motorized dampers and multiple thermostats. A stuck damper or failed zone board can leave one level cold even though the furnace itself runs fine.
Newer construction is built airtight, so airflow problems show up fast. A dirty filter or restricted return can trip the high-limit switch and shut the furnace down, which feels like a failed system but is often a simple airflow fix.
Vaulted great rooms let warm air rise away from living space, and ridge-top lots catch cold wind on winter nights. Systems sized only to floor area struggle in these rooms, which points to load, ducting or zoning.
Whether a zone stopped heating or a builder-grade furnace is out of warranty, every service below is handled by our own licensed technicians.
Ignitors, flame sensors, blowers and zone control boards on 2000s-era systems, often fixed on the first visit.
New furnaces sized to your real load, including multi-stage and zoned setups for larger plans.
A planned swap when a builder-grade furnace is out of warranty and repair bills are stacking up.
Yearly service that keeps a tight, newer home's furnace breathing freely and under warranty.
Filter, sensor and blower checks that clear the airflow problems newer homes are prone to.
Combustion and venting checks suited to sealed, energy-efficient construction.
Fast response when heat fails, including ridge-top lots that feel cold wind first.
Multi-stage and variable-speed gas furnaces repaired and installed for roomy two-story homes.
Heat pumps that handle both seasons in larger homes, sized with high ceilings in mind.
Mini-splits for lofts, upper floors and vaulted spaces the main system cannot balance.
Findings on damper, board and sensor faults explained in writing before any repair.
Smart thermostats and zone controls that even out temperatures between floors.
Duct balancing and damper work for long runs to far rooms and upper levels.

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.

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.

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.
