We specialize in providing seamless, professional AC replacement services for homeowners throughout Diamond Bar, ensuring you get the perfect cooling solution tailored to your specific needs.

Is It Time to Repair or Replace Your Air Conditioner?
Deciding whether to sink more money into repairing an aging unit or invest in a new one can be a challenging decision. While a minor repair might seem cost-effective upfront, it can often be a temporary fix for a system that is nearing the end of its lifespan. Here are key indicators that an AC replacement is the more prudent long-term investment for your Diamond Bar home:
- Age of the System: Most central air conditioners have a lifespan of 12-15 years. If your unit is in this age range or older, it is operating on outdated technology and is far less efficient than modern systems. Continuing to repair it often leads to diminishing returns.
- Frequent and Costly Breakdowns: Are you calling for repairs every summer? If your repair costs are adding up, especially if a single repair exceeds a significant portion of the cost of a new unit, replacement is the smarter financial choice. A common guideline is the "$5,000 Rule": if the age of your unit multiplied by the cost of the repair is more than $5,000, it’s time to replace.
- Skyrocketing Energy Bills: An old, inefficient air conditioner has to work much harder to cool your home, leading to a noticeable spike in your electricity costs. A new, high-efficiency model can dramatically lower your monthly utility bills, often providing significant savings that help offset the initial investment.
- Poor Cooling Performance: If your AC runs constantly but your home still has hot spots or never feels quite cool enough, the system may be improperly sized or simply losing its cooling capacity due to age and wear.
- Use of R-22 Freon: If your system was installed before 2010, it likely uses R-22 refrigerant. This substance has been phased out due to environmental concerns, making it extremely expensive and difficult to source for repairs. Upgrading to a new system that uses modern, eco-friendly R-410A refrigerant is a more responsible and sustainable choice.
Upgrade to Superior Comfort with High-Efficiency and Premium Systems
Modern air conditioning technology has advanced significantly beyond simple cooling. Today’s high-efficiency and premium systems, including top-tier premium series models, offer a level of comfort, control, and energy savings that older units simply cannot match. When you choose to upgrade, you’re not just replacing a machine; you’re investing in a better home environment.
The key measure of efficiency is the Seasonal Energy Efficiency Ratio (SEER). While older systems may have a SEER rating of 10 or less, current regulations require a minimum of 14 SEER. High-efficiency models boast ratings of 18, 20, or even higher. This translates directly into lower energy consumption and substantial savings over the life of the unit.
Beyond SEER ratings, premium systems offer advanced features that redefine home comfort:
- Variable-Speed Technology: Unlike old single-stage systems that blast on at full power and then shut off, variable-speed compressors and air handlers make minute adjustments to their output. This allows them to run for longer periods at very low power, resulting in more consistent temperatures, superior humidity control, and whisper-quiet operation.
- Enhanced Air Filtration: Advanced systems come equipped with superior filtration capabilities that capture dust, pollen, pet dander, and other airborne contaminants, significantly improving your home’s indoor air quality.
- Smart Thermostat Integration: Seamlessly connect your new AC to a smart thermostat for ultimate control. Adjust temperatures from your smartphone, set schedules, and let the system learn your habits to optimize energy usage automatically.

We believe that a flawless installation is just as important as the quality of the unit itself. Our process is designed to be thorough, transparent, and hassle-free for you, ensuring your new system performs at its peak from day one.
- In-Depth Home Assessment: Our process begins with a comprehensive evaluation of your home. We don’t just look at your old unit; we assess your home's square footage, insulation, window placement, and existing ductwork to determine the precise cooling load required.
- Expert System Recommendation: Based on our assessment and your budget, we recommend a selection of systems perfectly sized for your home. We’ll walk you through the benefits of different models and efficiency ratings, helping you make an informed decision without any sales pressure.
- Professional Removal and Installation: Our certified technicians will carefully and cleanly remove your old air conditioning unit and all related components. We then install your new system according to strict manufacturer specifications and local Diamond Bar building codes, ensuring all connections are secure and the system is calibrated for optimal performance.
- System Testing and Walkthrough: Once the installation is complete, we don’t leave until we have thoroughly tested the entire system. We check refrigerant levels, airflow, and electrical connections to confirm everything is working perfectly.

Ruben, was incredibly responsive, addressing all my inquiries promptly and with clear, thorough explanations. Their dedication to understanding and meeting my needs was remarkable.
Ruben, went above and beyond to ensure that everything was handled seamlessly, demonstrating not just professionalism, but also a sincere dedication to customer satisfaction.
I can't recommend Piggies air Conditioning/Ruben highly enough. If you're looking for someone who combines expertise with exceptional service, look no further. They are a true example of what outstanding professionalism should be.








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.
Also cant leave the amazing Luis & Miles out of
this review.
They came, they saw, they conquered!
And they worked pretty swiftly too, felt very comfy around em, loved their personalities, great attitude, work ethic, professionalism, had some really good convos & they still got the job done lightning fast
SUPER HUGE SHOUT OUT & THANKS for everything guys! Definitely recommending u guys to everyone i know.




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.
