Professional Heat Pump Installation in Walnut, CA
Choosing to install a heat pump is a smart investment in your Walnut home’s year-round comfort and energy efficiency. This single, versatile system provides powerful cooling during our hot summers and reliable heating for our mild winters. However, the performance, efficiency, and lifespan of your new heat pump depend almost entirely on the quality of its installation. An improper setup can lead to years of high energy bills, inadequate comfort, and premature system failure.
At our core, we believe that a superior installation is not just a service, but a craft. It’s the critical final step that transforms advanced HVAC technology into tangible comfort and savings for your family. At Piggies Air Conditioning, our team of certified technicians specializes in providing meticulous, code-compliant heat pump installations specifically for homes in the Walnut, CA area, ensuring your system operates at peak performance from day one.

The Critical Difference of a Professional Installation
You can purchase the most expensive, highest-rated heat pump on the market, but if it’s installed incorrectly, you will never experience its full benefits. Many common HVAC issues are not due to equipment defects but are direct results of a flawed installation process.
Here’s why a professional, detail-oriented installation is non-negotiable:
- Accurate System Sizing: The most common mistake in HVAC installation is incorrect sizing. A unit that’s too small will run constantly, struggling to heat or cool your home and driving up energy costs. A unit that’s too large will short-cycle—turning on and off frequently—failing to properly dehumidify the air and causing unnecessary wear on components. We perform a detailed load calculation (Manual J) to determine the precise size your Walnut home needs.
- Ensuring Maximum Efficiency: Your heat pump’s SEER2 (cooling) and HSPF2 (heating) ratings are achieved only under ideal installation conditions. We ensure correct refrigerant charging, proper airflow, and sealed ductwork, allowing your system to operate at the high-efficiency levels advertised by the manufacturer.
- Safety and Code Compliance: Heat pump installation involves high-voltage electrical connections and pressurized refrigerant lines. Our licensed technicians adhere strictly to all local Walnut building codes and national safety standards, protecting your home and family.
- Protecting Your Warranty: Most manufacturers will void their comprehensive parts warranty if the system is not installed by a licensed and certified HVAC professional. Our professional installation ensures your valuable investment is fully protected.
- Longevity of Your System: A correctly installed heat pump experiences less strain on critical components like the compressor and fan motors. This translates directly to fewer breakdowns and a significantly longer operational lifespan.
Our Comprehensive Heat Pump Installation Process
We have refined our installation process to be transparent, thorough, and focused on long-term performance. We leave nothing to chance, ensuring every step is executed with precision.
Step 1: In-Depth Home Assessment
Our process begins not with a sales pitch, but with a detailed evaluation of your home. A technician will visit your Walnut property to perform a comprehensive load calculation. We assess key factors including your home's square footage, insulation levels, window type and orientation, air leakage, ceiling height, and ductwork integrity. This data-driven approach is the only way to accurately size a system for your specific needs.
Step 2: System Selection and Custom Recommendation
Based on our assessment, we will walk you through the best heat pump options for your home and budget. We explain the benefits of different models, from single-stage to variable-speed inverter systems, and help you understand the efficiency ratings (SEER2, HSPF2) so you can make an informed decision. We recommend reliable equipment that is well-suited to the Southern California climate.
Step 3: Meticulous Site Preparation
Before any equipment is installed, we prepare the area to ensure optimal placement and function. This includes preparing a solid, level pad for the outdoor condenser unit, ensuring it has adequate clearance for airflow and service access. We also prepare the indoor location for the air handler, planning for proper drainage and accessibility.
Step 4: Expert Equipment Installation
Our certified technicians carry out the physical installation with meticulous care. This includes:
- Setting the new outdoor and indoor units.
- Expertly brazing the copper refrigerant lines to create a permanent, leak-proof seal.
- Safely connecting all high and low-voltage electrical wiring according to code.
- Installing a new, compatible smart thermostat for optimal control and efficiency.
- Ensuring the condensate drain line is properly sloped and routed to prevent water backups and potential property damage.
Step 5: System Commissioning and Performance Testing
This is where true professionals set themselves apart. We don't just turn the system on; we commission it. This involves a rigorous series of tests and calibrations:
- Refrigerant Charging: We charge the system with the exact amount of refrigerant specified by the manufacturer, verifying the levels with digital gauges for absolute precision.
- Airflow Verification: We test the static pressure of your duct system to ensure air is moving freely and efficiently throughout your home.
- Cycle Testing: We run the system through complete heating and cooling cycles to confirm every component is functioning correctly and delivering the right air temperature.
- Safety Checks: We verify all safety controls and electrical connections are working as they should.
Step 6: Homeowner Orientation
Once we are 100% satisfied with the installation and performance, we clean our work area completely. We then provide you with a full walkthrough of your new system, showing you how to operate the thermostat, explaining routine maintenance like changing the air filter, and answering any questions you have. We aren’t finished until you are comfortable and confident with your new heat pump.

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.
