Expert Furnace Repair in Sierra Madre, CA
When your furnace fails, the comfort and safety of your Sierra Madre home are immediately compromised. A sudden cold snap becomes more than an inconvenience; it becomes a pressing problem that demands a fast, reliable solution. Whether you’re dealing with a system that won’t turn on, strange noises coming from your vents, or a pilot light that refuses to stay lit, you need professional help from technicians who understand the urgency and complexity of the situation. Our team provides expert furnace diagnostics and repairs, ensuring your home’s heating is restored efficiently and correctly.

Signs Your Furnace Needs Immediate Attention
It’s not always obvious when a furnace is on the brink of a complete breakdown. Recognizing the early warning signs can help you avoid a no-heat emergency and prevent more expensive damage down the line. If you notice any of the following symptoms, it’s time to schedule a professional inspection.
- Insufficient or No Heat: The most apparent sign of a problem is a furnace that blows cool air or fails to produce any heat at all.
- Unusual Noises: Banging, popping, squealing, or grinding sounds indicate mechanical issues that require professional diagnosis. A loud bang could signal a serious ignition problem, while grinding may point to worn-out motor bearings.
- Frequent Cycling: If your furnace turns on and off more frequently than usual, it could be a sign of a clogged filter, improper airflow, or a malfunctioning thermostat.
- Higher Energy Bills: A sudden, unexplained spike in your utility costs often means your furnace is working harder than it should to heat your home, signaling an efficiency problem.
- Yellow Pilot Light: A healthy pilot light should be a steady blue. A yellow or flickering flame can indicate a ventilation issue or the presence of carbon monoxide.
- Poor Air Quality: An increase in dust, soot, or dry air in your home can be traced back to a poorly functioning furnace or ductwork in need of cleaning.
Comprehensive Furnace Repair Solutions for Your Home
Our certified technicians are equipped to handle a wide range of furnace malfunctions. We don't just fix the surface-level problem; we perform a thorough diagnosis to identify the root cause, ensuring a lasting and reliable repair.
Furnace Won't Turn On
A furnace that fails to start can be caused by several issues, from thermostat malfunctions and tripped circuit breakers to problems with the pilot light or electronic ignition system. Our technicians systematically check each component to pinpoint the exact point of failure and restore power and function to your unit safely.
Strange Noises (Banging, Squealing, Grinding)
Unusual sounds are your furnace’s way of signaling distress. Squealing often points to a problem with a belt or motor bearing, while grinding suggests a more serious motor issue. A loud banging sound upon startup can indicate delayed ignition, a potentially dangerous situation. We diagnose these sounds to their source and perform the necessary repairs to ensure quiet, safe operation.
Pilot Light or Ignition Control Failures
For older furnaces, a pilot light that won't stay lit is often due to a faulty thermocouple or a clog in the gas tube. In modern systems, electronic ignition failures can prevent the furnace from starting altogether. We specialize in repairing and replacing these critical components to restore your furnace’s heating capability.
Malfunctioning Thermostat
Sometimes the problem isn’t the furnace itself, but the thermostat that controls it. Inaccurate temperature readings, lost connections, or a complete failure can prevent your furnace from operating correctly. We can diagnose thermostat issues, recalibrate the device, or recommend a suitable replacement.
Constant Blower Fan Operation
If the blower fan runs continuously, it could be a simple issue like a mis-set thermostat fan switch or a more complex problem with the furnace's limit switch. Our technicians will investigate the control system to find the cause and stop the blower from running unnecessarily, saving you energy and reducing wear and tear.
Deciding Between Furnace Repair and Replacement
As your furnace ages, you may face the critical decision of whether to invest in another repair or replace the entire unit. We believe in providing honest guidance to help Sierra Madre homeowners make the best choice for their budget and long-term comfort.
Consider these factors:
- Age of the Furnace: If your furnace is over 15 years old, it is approaching the end of its typical lifespan. Investing in a new, high-efficiency model may be more cost-effective than continuing to pay for repairs on an aging system.
- Frequency of Repairs: Are you calling for service every year? Frequent breakdowns are a clear sign that your furnace is losing reliability. The cumulative cost of these repairs can quickly add up.
- Cost of the Repair: A common guideline is the "$5,000 Rule." Multiply the cost of the repair by the age of your furnace. If the total exceeds $5,000, replacement is often the more sensible financial decision.
- Energy Efficiency: Older furnaces are significantly less efficient than modern units. Upgrading can lead to substantial savings on your monthly energy bills, helping the new system pay for itself over time.
- Safety Concerns: An older furnace with a cracked heat exchanger can leak carbon monoxide into your home. If a major safety issue is discovered, replacement is non-negotiable.

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.

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.
