We are very pleased with the repairs and friendly service provided by Eladio of Happy Camper. They had him come out to our home within two hours of my call for urgently needed AC repairs when no other firm was able to the same day.
They came in they were professional they were clean. They picked up after themselves. They did a great job. They fixed the problem and it is surprisingly family owned. Juan is the owner and he is wonderful and very thorough.
Same day service was prompt, polite, and quick. Talked with me in detail about the issues and options, and didn’t try to upsell the entire system cleaning while I had no AC (the fact that I was able to pay for just what I asked for was great)
Excellent service. I was helped by Technician Eladio, he was very professional, polite and thorough. After completing the inspection of both the inside and outside units, he provided me with the details of work required and my options of service. Allowing me to choose my best option without pressure.
Juan from Happy Camper did an excellent job cleaning my AC unit and was very thorough in his inspection of the entire HVAC system. He answered all my questions and was very professional. I will be calling Happy Camper for future HVAC needs.
I am so glad that we decided to trust Happy Campers with the installation of our dual HVAC system. From the very start, Juan was SO patient with all & any questions that we had. I remember that initial encounter, & knew that from the other companies that we inquired, Happy Camper was the company that we wanted to work with.
From start to finish they have been so professional and made this process of updating our air conditioning system very easy. Communication and scheduling was quick and pricing is very reasonable. Definitely happy with their work! Will for sure be using them again.
Everything was done quickly and they were very informative the whole way through and took their time explaining the systems in what they do and how they work. Would recommend and will be calling them back if I need any more repairs done!
Juan and his team came out to check our HVAC system. He was very thorough and professional. He is very knowledgeable and does a great job determining the issues first then explaining possible solutions. Overall it was a good experience and would recommend happy camper to anyone looking for HVAC services.
If I could give 10 stars, I would! Juan showed up right on time and was eager to identify the problem and fix our plumbing issues. Not only was he extremely kind, but very knowledgeable in his field! He was able to figure out the problem in no time and offered multiple solutions to our problem to fit our budget.
What a really great company! Juan and his team are very professional, very knowledgeable and extremely courteous. I have a toddler and this team goes above and beyond to make sure the place is cleaner than how they found it. I have called Juan numerous times for various quotes and jobs and will continue to do so.

Cerritos is a city of well-established neighborhoods with a large share of homes built between the 1960s and 1980s. That housing stock often means aging ductwork, original or older-generation equipment, and electrical systems that weren’t designed with today’s high-efficiency units in mind. Repair needs here tend to be a little different than in newer developments.
Our technicians are trained to work across all major makes and models, and they understand the quirks of older systems common throughout Los Angeles County. We diagnose the root problem rather than patching symptoms, so you’re not calling us back for the same issue a month later.
Our AC repair services cover a full range of issues including refrigerant leaks and recharges, compressor and capacitor failures, blower motor and fan problems, frozen evaporator coils, thermostat and electrical faults, and drainage line clogs. We work on central air systems, mini-splits, and heat pumps, and we always explain what we found and what we recommend before any work begins.
Southern California’s heat waves can mask early warning signs—your system may still be running even as it quietly fails. These are the signals Cerritos homeowners most commonly overlook until things get worse.
If any of these sound familiar, it’s worth scheduling a diagnostic before the problem grows. Catching issues early almost always means a smaller repair bill.
The flat, low-elevation terrain of Cerritos traps heat during summer inversions, meaning air conditioners here run longer and harder than in coastal or elevated areas nearby. That sustained load accelerates wear on specific components in predictable ways.
Refrigerant leaks are among the most frequent issues we see, particularly in systems more than ten years old. As coils and line sets age, small cracks develop and refrigerant slowly escapes—leaving the system unable to cool effectively even when everything else appears functional. Capacitor failures are similarly common, especially after heat waves put the compressor under extended strain. A failing capacitor is often what causes a unit to hum but not start.
Dirty condenser coils are a year-round concern in Cerritos. The area’s dry winds carry fine dust and particulate matter that coat outdoor units and reduce their ability to shed heat. Without regular cleaning, efficiency drops and component temperatures climb. Clogged condensate drains are also a frequent culprit—particularly relevant here given how hard systems work during peak months—and a blocked drain can cause water damage or trigger a safety shutoff that leaves your home without cooling.
We got a call from Maria on a Tuesday afternoon in late July. Her home in the Briarglen neighborhood had been running warm for a couple of days, and the night before, the system stopped keeping up entirely. By the time our technician arrived, the indoor temperature had climbed past 85 degrees.
The unit was a central system that had been in place since the home was built in the mid-1970s—original to the house, with the original air handler still in the attic. The technician found a failed run capacitor on the compressor and a condenser coil coated in a thick layer of dust and debris that had been reducing airflow for who knows how long.
We replaced the capacitor and did a full coil cleaning on the spot. The system was back up and running within two hours, and by the time we left, Maria’s home was cooling down and she had a clear picture of the system’s overall condition and what to watch for going forward. That’s the kind of service we aim to deliver every time.
Cerritos homeowners have plenty of options when it comes to HVAC service. Here’s what sets us apart.
We built this company on the idea that every customer deserves to be treated like family—and that doesn’t change when the call is routine or when it’s a weekend emergency in the middle of a heat wave.
We offer same-day and emergency service throughout the Cerritos area. Call us and we’ll give you a realistic arrival window—then we show up on time.
Yes, always. We provide full upfront pricing after our diagnostic so you know exactly what you’re approving before any work begins. No surprises on the final bill.
That depends on the repair cost, the system’s overall condition, and how it’s been performing. Our technician will give you an honest assessment and help you weigh your options—we’re not here to push you toward a replacement if a repair makes more sense.
Close blinds and curtains to block direct sun, avoid using heat-generating appliances, and make sure the thermostat is set to cool. If the system is making unusual sounds or you smell something burning, turn it off at the breaker and let us know when you call.
Yes. We work on central air systems, ductless mini-splits, and heat pumps. Whether your home has a newer system or older equipment, our technicians have the experience to diagnose and repair it.
