Is It Time to Replace Your Furnace?
It can be difficult to know whether a simple repair will suffice or if a full replacement is the more cost-effective and safer option. If you're experiencing any of the following issues, it's a strong indication that your system is nearing the end of its operational life and a replacement should be seriously considered.
- Your Furnace is Over 15 Years Old: The average lifespan of a furnace is between 15 and 20 years. If your unit is in this age range, it's operating on borrowed time. Modern units are significantly more efficient, and replacing an older model proactively can prevent a sudden, inconvenient breakdown during a cold snap.
- Rising Heating Bills: Have you noticed your gas or electric bills creeping up each winter without a change in your usage habits? As furnaces age, they lose efficiency, requiring more fuel to produce the same amount of heat. A new high-efficiency model can dramatically reduce your monthly energy consumption.
- Frequent and Costly Repairs: If you find yourself calling for repairs every year, the cumulative cost can quickly approach the price of a new unit. Investing in a replacement ends the cycle of constant breakdowns and provides you with the peace of mind that comes with a new manufacturer's warranty.
- Uneven Heating and Inconsistent Comfort: Are some rooms in your house warm and cozy while others remain chilly? This is often a sign that your aging furnace can no longer distribute air effectively. A properly sized and installed new furnace will provide consistent, even heat throughout your entire home.
- Loud or Unusual Noises: While all furnaces make some noise, sounds like rattling, banging, popping, or squealing are clear warning signs. These noises can indicate serious mechanical problems, such as a cracked heat exchanger or a failing blower motor.
- Visible Rust or Cracks: Physical deterioration on the furnace unit is a major red flag. Rust can lead to corrosion that compromises components, while cracks in the heat exchanger can leak dangerous carbon monoxide into your home.
- Yellow Pilot Light: A healthy furnace pilot light should be a steady blue. If the flame is yellow, flickering, or appears weak, it could indicate a combustion problem or a ventilation issue, posing a carbon monoxide risk.
Our Comprehensive Monrovia Furnace Replacement Process
At Piggies Air Conditioning, we believe a successful furnace replacement goes far beyond simply swapping out the old unit for a new one. It involves a detailed, methodical approach tailored to the unique specifications of your Monrovia home.
In-Depth Home Assessment
Our process begins with a thorough evaluation of your home's heating requirements. A technician will perform a "load calculation" to determine the precise size and capacity of the furnace needed. We assess factors like your home's square footage, insulation levels, window quality, and existing ductwork. Installing a furnace that is too large or too small can lead to inefficiency, premature wear, and uncomfortable temperature swings. This critical first step ensures your new system is perfectly matched to your home.
Guidance on Modern, Energy-Efficient Models
We help you navigate the options to select the best furnace for your needs and budget. We’ll explain the benefits of modern features like variable-speed blowers for quieter operation and improved air circulation, as well as the importance of the Annual Fuel Utilization Efficiency (AFUE) rating. A higher AFUE rating means more of your fuel is converted directly into heat for your home, translating to lower utility bills.
Professional Removal and Disposal
Our certified technicians will safely disconnect and remove your old furnace. This includes managing all electrical wiring, gas lines, and venting with meticulous care. We handle the responsible disposal of the old unit according to environmental regulations, leaving your space clean and ready for the new installation.
Meticulous and Code-Compliant Installation
The installation of your new furnace is the most critical phase. Our team performs every step with precision, ensuring all connections—electrical, gas, and ductwork—are secure and sealed. We adhere strictly to all Monrovia and California state building codes to guarantee the safety and performance of your new system. Once installed, we test the unit extensively to confirm it is operating at peak efficiency.
System Calibration and Final Walkthrough
We don’t consider the job finished until you are completely comfortable with your new system. We calibrate the thermostat, test the airflow in every room, and conduct a final safety check. Our technician will then walk you through the operation of your new furnace and thermostat, answering any questions you have and providing tips for optimal performance.

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.
