Is It Time to Replace Your Furnace? Key Warning Signs
Deciding whether to furnace repair or replace your furnace can be challenging. While a minor repair might offer a temporary fix, recurring problems often signal that the system is nearing the end of its operational life. Homeowners in San Marino should watch for these clear indicators that a full replacement is the smarter long-term investment.
- Your Furnace is Over 15 Years Old: Most furnaces have a lifespan of 15 to 20 years. An older unit, even if it seems to be working, operates far less efficiently than modern systems and is more prone to sudden, critical failures.
- Rising Energy Bills: Have you noticed a steady increase in your heating costs without a change in your usage habits? As furnaces age, they lose efficiency, consuming more fuel to produce the same amount of heat. A new high-efficiency model can significantly lower your monthly utility expenses.
- Frequent and Costly Repairs: If you find yourself scheduling repairs every season, the cumulative costs can quickly approach the price of a new unit. A general rule of thumb is if a repair costs more than 50% of a new furnace, replacement is the more financially sound choice.
- Inconsistent Heating and Comfort: Are some rooms in your home warm while others remain chilly? A struggling furnace often loses its ability to distribute heat evenly, leading to uncomfortable temperature fluctuations throughout your house.
- Strange Noises or Odors: Banging, rattling, or screeching sounds can indicate serious mechanical issues, such as a cracked heat exchanger or a failing blower motor. These problems can compromise both performance and safety.
- Visible Signs of Rust or Cracks: Any visible corrosion or cracks on the furnace components are serious warning signs that require immediate professional attention, as they can lead to dangerous carbon monoxide leaks.
Our Comprehensive Furnace Replacement Process
Piggies Air Conditioning believes in a meticulous and transparent process that puts your needs first. Our goal is to equip your San Marino home with the perfect heating system, installed with precision and care.
Step 1: In-Home Consultation and System Sizing
Our process begins with a thorough assessment of your home and heating requirements. A technician will evaluate your existing system, inspect your ductwork, and discuss your comfort preferences and budget. We perform a professional load calculation (Manual J) to determine the exact size furnace your home needs. Proper sizing is critical—a unit that is too large or too small will operate inefficiently, increase wear and tear, and fail to provide optimal comfort.
Step 2: Selecting the Right High-Efficiency Furnace
Based on our assessment, we will present you with a curated selection of modern, energy-efficient furnaces. We’ll explain the key differences, focusing on the Annual Fuel Utilization Efficiency (AFUE) rating. A higher AFUE rating means more of your fuel is converted directly into heat for your home, resulting in lower energy consumption. We help you choose the ideal system, whether it's a natural gas furnace or an electric model, that aligns with your home’s needs and your energy-saving goals.
Step 3: Professional and Code-Compliant Installation
Our certified technicians handle every aspect of the installation with expert precision. This includes the safe disconnection and removal of your old unit, making any necessary adjustments to your ductwork or ventilation, and flawlessly installing the new furnace according to manufacturer specifications and all San Marino building codes. We treat your home with respect, ensuring a clean and orderly work area from start to finish.
Step 4: System Testing and Homeowner Walkthrough
Once the installation is complete, we don’t just leave. We conduct a series of rigorous tests to ensure every component of your new furnace is operating at peak performance. We then walk you through the new system, explaining its features, how to operate the thermostat, and providing tips for optimal performance and maintenance. We want you to feel confident and comfortable with your new heating investment.
The Lasting Benefits of a New Furnace Installation
Investing in a new furnace provides more than just reliable heat. It enhances your home and lifestyle in several significant ways.
- Improved Energy Efficiency: Modern furnaces are dramatically more efficient than models from a decade ago, translating directly into lower monthly energy bills.
- Enhanced Home Comfort: A new, correctly sized furnace delivers consistent, even heating to every corner of your home, eliminating cold spots and drafts.
- Increased Safety and Peace of Mind: New systems come with advanced safety features that protect your family from risks like carbon monoxide leaks.
- Quiet Operation: Advanced technology in modern furnaces means they operate much more quietly than older, clunkier models, contributing to a more peaceful home environment.
- Long-Term Reliability: With a professional installation and a new manufacturer's warranty, you can enjoy years of worry-free performance without the stress of unexpected breakdowns.

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.
