Why Expert Repair is Non-Negotiable for Your AC
Standard air conditioning units and high-performance AC systems operate on fundamentally different principles. The advanced technology that delivers their superior performance also makes them more complex to service. Attempting a repair without specialized knowledge can lead to further damage, reduced efficiency, and even void your warranty.
Advanced System Complexity: AC units often feature variable-speed compressors, communicating indoor and outdoor units, sophisticated inverter boards, and multiple electronic sensors. These components work in harmony to modulate cooling output precisely. A technician must understand how this entire system communicates to accurately diagnose an issue, which could stem from a mechanical fault, a sensor failure, or a software glitch.
Maintaining Peak Efficiency: One of the primary reasons you chose a system was likely its exceptional energy efficiency rating. An improper repair, such as an incorrect refrigerant charge or the use of a non-compatible part, can drastically compromise this efficiency. This means your system will work harder, consume more energy, and cost you more on your monthly utility bills, negating the very benefits you invested in.
Specialized Diagnostic Tools: Identifying the root cause of a problem in a AC often requires more than a standard pressure gauge. We utilize advanced diagnostic equipment that interfaces directly with your system's control board. This allows us to read specific error codes, analyze performance data, and pinpoint the exact component that is failing, saving time and preventing guesswork.
Preserving Longevity and Performance: A high-performance system is built with high-quality components designed to last. Our repair philosophy is centered on restoring your unit to its factory specifications. We use premium, manufacturer-approved parts and follow precise repair protocols to ensure your system continues to operate reliably and effectively for years to come.
Common and Complex AC Issues We Resolve
Our technicians possess deep experience in troubleshooting the unique challenges presented by premium air conditioning systems. We go beyond common fixes to address the complex electrical and mechanical issues specific to these advanced units.
- Inverter and Compressor Malfunctions: The variable-speed compressor is the heart of your system. We are skilled in diagnosing issues with the inverter drive that powers it, addressing everything from unusual noises to a complete failure to cool.
- Communication Errors: If the indoor and outdoor units cannot communicate effectively, the entire system can shut down or perform erratically. We trace these communication faults through complex wiring and control boards to restore proper function.
- Sensor and Thermostat Failures: Your system relies on a network of sensors to monitor temperature, pressure, and humidity. A single faulty sensor can cause improper cooling cycles. We accurately identify and replace malfunctioning sensors and address issues with proprietary smart thermostats.
- Refrigerant Leaks and Charging: High-efficiency systems require an exact refrigerant charge. Too much or too little can damage the compressor and reduce efficiency. We use precise methods to locate and repair leaks and recharge the system to the manufacturer's exact specifications.
- Control Board Diagnostics: The electronic control board is the brain of your AC. We have the expertise to diagnose board-level issues and determine if a repair or replacement is the most effective solution.

The technician arrived on time, which I really appreciated given how crucial air conditioning is in this heat. Ruben was professional and friendly, explaining what he was doing throughout the process. The issue I had was diagnosed fairly quickly, and they provided me with a few options on how to fix it. The pricing was transparent, and I didn't feel like there were any hidden costs, which is always a plus when it comes to service calls like these. Highly recommend this company!




1st & foremost, huge shout out to Ruben thank u so so much for reaching out & making things happen SO FAST! I was so surprised since i had reached out to a couple different places who lagged on even answering calls, messages, etc.
Ruben was also very informative & taught me ALOT that i didnt know about.

recommendations and feedback. The actual installation was painless and unremarkable, his AC experts got it done, got it cleaned and most importantly got it right. Rueben even went a step further to assure we had
protection from the coming rain, that is service unheard of these days. His price was competitive and a REAL value for the service we recieved. Using anyone else for your AC needs, would be a huge mistake. We thank them again and will recommend to everyone.




Echoing a lot of the other reviews here, Piggies Air Conditioning responds so quickly to requests (even though I actually accidentally sent in multiple requests on my side without responding, oops!)
They were able to come do a FREE energy audit and initial inspection on the same day and Ruben was amazing at explaining his thoughts on our house's situation and what he thought was worth the money and wasn't worth the money.
I truly felt like he was trying to help me find the best solution to our issues instead of just trying to upsell us on everything and anything.
I'm definitely recommending this business to anyone I know if they want a trustworthy and realistic service, value, and quality.
