Professional AC Replacement in Walnut, CA
When the Southern California sun beats down, a failing air conditioner isn’t just an inconvenience—it’s a major disruption to your comfort and peace of mind. For homeowners in Walnut, an outdated, inefficient, or broken AC unit can lead to soaring energy bills and unreliable cooling when you need it most. An AC replacement is a significant investment in your home, and our goal is to make the process transparent, seamless, and tailored to deliver lasting comfort and value. Piggies Air Conditioning specializes in replacing old systems with modern, energy-efficient solutions designed to handle the specific climate demands of Walnut, CA.

Is It Time for an AC Replacement? Key Signs to Watch For
Many homeowners grapple with the decision to repair or replace their air conditioner. While a simple repair might seem like the cheaper option upfront, pouring money into an aging system often costs more in the long run. Here are the clear indicators that it’s time to consider a full system replacement:
- Your System is Over 10-15 Years Old: Even well-maintained air conditioners lose efficiency and become more prone to failure as they age. If your unit is in this age range, replacement is often the most cost-effective choice.
- Frequent and Costly Repairs: Are you calling for repairs every summer? If a single repair costs 30-50% of a new unit, or if the cumulative repair costs are adding up, that money is better invested in a new, reliable system.
- Skyrocketing Energy Bills: An old AC has to work much harder to cool your home, leading to a noticeable spike in your electricity bills. A new high-efficiency unit can drastically reduce your monthly cooling costs.
- Inconsistent Cooling and Hot Spots: If some rooms are freezing while others are uncomfortably warm, your system may be improperly sized or losing its capacity to cool your home evenly.
- Strange Noises or Odors: Loud grinding, rattling, or buzzing sounds can signal serious mechanical failure. Musty odors may indicate issues with mold or moisture inside your unit or ductwork.
- Uses R-22 Freon: This refrigerant has been phased out due to environmental concerns. If your older system uses R-22, the cost of recharging it is extremely high, making replacement a much smarter financial decision.
Our Comprehensive AC Replacement Process
We believe in a meticulous, customer-focused approach to ensure your new air conditioning system is a perfect fit for your home and budget. Our process is designed for clarity and precision from start to finish.
Step 1: In-Depth Home Assessment
Our process begins with a thorough evaluation of your home. We don’t rely on guesswork. Our certified technicians perform a professional Manual J load calculation, which considers factors like your home’s square footage, insulation levels, window placement, ceiling height, and local Walnut climate data. This ensures we recommend a system that is perfectly sized for optimal performance and efficiency—never too big or too small.
Step 2: Custom System Recommendation
Based on our assessment and your specific needs, we present you with tailored options. We’ll walk you through the benefits of different types of systems, such as high-efficiency central air conditioners or versatile ductless mini-splits. We explain modern efficiency standards like SEER2 ratings, helping you understand the long-term energy savings associated with each option.
Step 3: Safe Removal of the Old Unit
Once you’ve selected your new system, our team carefully and cleanly removes your old air conditioner. We handle the entire process with respect for your property and ensure the old equipment is disposed of in an environmentally responsible manner, adhering to all regulations.
Step 4: Precision Installation
This is where expertise matters most. Our technicians install your new system according to the manufacturer’s exact specifications and local building codes. This includes making precise connections to your home’s electrical system, refrigerant lines, and existing ductwork. We also inspect ductwork to identify any leaks or issues that could compromise performance.
Step 5: System Testing and Calibration
After installation, we don’t just turn the system on and leave. We conduct a series of rigorous tests to calibrate your new AC. We check refrigerant levels, test airflow throughout your home, and ensure every component is functioning at peak efficiency to deliver the comfort and savings you expect.
Step 6: Homeowner Walkthrough and Education
Your satisfaction is our priority. We conclude every installation with a complete walkthrough, showing you how to operate your new system and smart thermostat. We’ll also provide essential maintenance tips to help you protect your investment and ensure it runs smoothly for years to come.
The Lasting Benefits of a New, Energy-Efficient AC
Upgrading your air conditioner is more than just a replacement; it’s an enhancement to your home and lifestyle. Homeowners in Walnut who invest in a new system enjoy a wide range of tangible benefits:
- Significant Energy Savings: Modern AC units with high SEER2 ratings are dramatically more efficient than models from a decade ago, leading to substantial reductions in your monthly utility bills.
- Enhanced and Consistent Comfort: A properly sized and installed system eliminates hot and cold spots, providing consistent, powerful cooling to every corner of your home while also improving humidity control.
- Improved Indoor Air Quality: New systems feature advanced filtration technology that captures dust, pollen, pet dander, and other airborne pollutants, creating a healthier living environment for your family.
- Whisper-Quiet Operation: Forget the loud clanking and rattling of your old unit. Modern air conditioners are engineered for quiet performance, allowing you to relax in peace.

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

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.
