Is It Time for a New Air Conditioner? Key Warning Signs
Deciding whether to repair or replace your air conditioner can be a tough decision. While a simple repair might seem cost-effective now, it can be a temporary fix for a system that is destined to fail. Watch for these clear indicators that it’s time to consider a full AC replacement.
- Your System is Over 10-15 Years Old: The average lifespan of an AC unit is about 15 years. If your system is approaching or has surpassed this age, it’s operating on borrowed time with outdated, inefficient technology.
- Frequent and Costly Repairs: Are you calling for repairs every summer? If a repair bill is more than a third of the cost of a new unit, replacement is the smarter financial choice.
- Soaring Energy Bills: An older AC has to work much harder to cool your home, causing a noticeable spike in your electricity costs. A new, energy-efficient model can significantly reduce your monthly bills.
- Poor or Inconsistent Cooling: If some rooms in your home are hot while others are cold, or if the system struggles to reach the set temperature on warm days, it’s a sign that your unit can no longer meet your home's cooling demands.
- Uses R-22 Freon: R-22 refrigerant has been phased out due to its environmental impact. If your older system uses it, repairs requiring a recharge will become increasingly expensive and difficult as supplies dwindle.
- Excessive Noise or Dust: Loud banging, grinding, or rattling noises indicate serious mechanical issues. Similarly, if your system is producing excessive dust, it may have problems with its internal components or ductwork.
A helpful guideline is the $5,000 Rule. Multiply the estimated cost of the repair by the age of your AC unit in years. If the total is more than $5,000, replacement is almost always the more economical option in the long run.
Our Comprehensive AC Replacement Process
We believe in making the AC replacement process straightforward and stress-free for San Dimas homeowners. Our method ensures you get the right system for your home, installed correctly for maximum performance and longevity.
Step 1: In-Home Consultation and System Sizing
There is no one-size-fits-all solution for home cooling. Our process begins with a thorough evaluation of your home. We perform a professional load calculation (Manual J) to determine the exact size and capacity of the air conditioner you need, considering factors like square footage, insulation levels, window placement, and your family's comfort preferences.
Step 2: Selecting the Right High-Efficiency System
Based on our assessment, we will walk you through the best options for your home and budget. We help you understand modern cooling technology, including:
- Central Air Conditioners: The traditional choice for whole-home cooling, modern units offer incredible efficiency.
- Ductless Mini-Split Systems: Perfect for homes without existing ductwork, additions, or for creating zoned cooling to save energy.
- Heat Pumps: An all-in-one solution that provides both highly efficient cooling in the summer and heating in the winter.
We’ll also explain SEER2 (Seasonal Energy Efficiency Ratio 2) ratings, so you can choose a unit that delivers the energy savings you desire.
Step 3: Professional Removal and Flawless Installation
Our certified and experienced technicians handle every aspect of the installation with meticulous care. We begin by safely and cleanly removing your old unit and preparing the space for the new system. We respect your property by using drop cloths and ensuring a tidy work area. The installation is performed according to manufacturer specifications and local San Dimas codes to guarantee optimal safety and performance.
Step 4: System Testing and Final Walk-Through
Once the installation is complete, we don’t just leave. We thoroughly test the new system to ensure every component is functioning perfectly. We calibrate the thermostat, check airflow, and verify cooling performance. Finally, we provide you with a detailed walk-through of your new air conditioner and smart thermostat, answering any questions you have to ensure you’re comfortable operating your new system.
The Benefits of a Modern AC System
Upgrading your air conditioner is an investment that pays you back in numerous ways.
- Reduced Energy Consumption: New AC units with high SEER2 ratings can cut your cooling costs by 30-50%, providing significant savings on your monthly utility bills.
- Enhanced Home Comfort: A properly sized and installed system eliminates hot spots, reduces humidity more effectively, and provides consistent, quiet cooling throughout your home.
- Improved Indoor Air Quality: Modern systems offer advanced filtration options that capture dust, pollen, pet dander, and other airborne contaminants, helping your family breathe easier.
- Increased Reliability and Peace of Mind: Stop worrying about your AC breaking down during a heatwave. A new system comes with a strong manufacturer's warranty and the promise of reliable performance for years to come.

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.
