The comfort and safety of your home are suddenly at risk, and you need a fast, reliable solution.

Our focus is on getting your system back online quickly, efficiently, and correctly the first time.

Telltale Signs Your Air Conditioner Needs Professional Repair
Ignoring the early warning signs of AC failure can lead to more extensive damage and costlier repairs down the line. If you notice any of the following issues, it’s time to schedule a professional inspection.
Blowing Warm or Weak Air
If the air coming from your vents isn't cold or the airflow is weak, it’s a clear sign of a problem. This could be caused by anything from low refrigerant levels and a failing compressor to clogged ductwork or a dirty air filter.
Strange Noises or Odors
Your air conditioner should operate with a consistent, low hum. Grinding, squealing, or clanking sounds often indicate serious mechanical issues, such as a failing motor or a loose component. Likewise, musty or burning smells can point to mold growth within the unit or dangerous electrical problems.
Unusually High Energy Bills
A sudden, unexplained spike in your electricity costs is often one of the first indicators that your AC is losing efficiency. The system is working harder and running longer to achieve the same level of cooling, signaling an underlying issue that needs to be addressed.
Constant Cycling or Running
An air conditioner that turns on and off too frequently (short cycling) or runs continuously without reaching the set temperature is struggling. This could be due to an improperly sized unit, a faulty thermostat, or a refrigerant leak.
Moisture and Leaks
While some condensation is normal, active water leaks around your indoor unit are not. This can be caused by a clogged condensate drain line, which can lead to water damage, mold growth, and system shutdowns if not resolved.
Our Comprehensive AC Repair Services
We offer a full spectrum of air conditioning repair services designed to address any issue your system might face. Our process begins with a meticulous diagnostic inspection to accurately identify the root cause of the problem, ensuring we perform the right repair.
Our skilled technicians are equipped to handle:
- Refrigerant Leak Detection and Recharge: We locate and seal refrigerant leaks and recharge your system to the manufacturer's precise specifications for optimal performance.
- Compressor and Fan Motor Repair: We service and repair critical components like the compressor and fan motors to restore proper airflow and cooling power.
- Evaporator and Condenser Coil Service: Dirty or frozen coils severely hinder your AC's ability to cool. We provide thorough cleaning and repair services to maximize efficiency.

Emergency AC Repair in Walnut
AC breakdowns don’t follow a 9-to-5 schedule. That’s why we offer responsive emergency repair services throughout Walnut. When your system fails unexpectedly, especially during a heatwave, you can count on our team to provide a rapid response to get your home cool and comfortable again.
The Smart Decision: Repairing vs. Replacing Your AC
One of the most common questions homeowners face is whether to invest in another repair or replace their aging air conditioner. As your trusted local experts, we provide honest guidance to help you make the best long-term decision for your home and budget. We consider several key factors:
- Age of the System: If your AC unit is over 10-15 years old, it is likely approaching the end of its operational lifespan. A new, high-efficiency model can offer significant energy savings and greater reliability.
- Frequency and Cost of Repairs: Are you scheduling repairs every year? If the cost of a current repair is more than 50% of the cost of a new unit, replacement is often the more financially sound option.
- Energy Efficiency (SEER Rating): Older systems have much lower SEER (Seasonal Energy Efficiency Ratio) ratings. Upgrading to a modern, high-SEER unit can drastically reduce your monthly cooling costs in Walnut's climate.
- Refrigerant Type: Many older systems use R-22 refrigerant, which is being phased out and is now extremely expensive. If your R-22 system has a significant leak, it often makes more sense to replace it than to pay for a costly recharge.
We will provide a clear, transparent assessment of your system’s health, giving you all the information you need to choose confidently between a high-quality repair and a cost-effective replacement.

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.
