The Essential Benefits of an Annual Furnace Tune-Up
Many homeowners wonder if a yearly furnace tune-up is truly necessary. The answer is an unequivocal yes. Just like a car, your furnace is a complex mechanical system that requires regular maintenance to operate at its best. Investing in an annual tune-up provides tangible returns for your San Marino home.
- Maximize Energy Efficiency: Over time, dust, and wear can force your furnace to work harder to produce the same amount of heat. Our technicians clean and calibrate key components, allowing your system to run more smoothly. This reduces energy consumption, which translates directly into lower monthly utility bills.
- Prevent Costly Breakdowns: The most common cause of major furnace failure is a lack of routine maintenance. During a tune-up, our experts can identify worn parts, loose electrical connections, or other potential problems. Addressing these small issues early can prevent a catastrophic system breakdown and save you from the expense of a major repair or premature replacement.
- Enhance Home Safety: Your furnace burns fuel to create heat, a process that must be carefully controlled. A critical part of our tune-up is a thorough safety inspection. We check for carbon monoxide leaks, inspect the heat exchanger for cracks, test safety controls, and ensure proper ventilation. This process is vital for protecting your family from potential hazards.
- Extend the Lifespan of Your System: A well-maintained furnace can last years longer than a neglected one. Regular cleaning, lubrication, and adjustments reduce the daily strain on your system’s components, preventing premature wear and tear. A tune-up is a direct investment in the longevity of your heating equipment.
- Maintain Your Manufacturer’s Warranty: Many furnace manufacturers require proof of annual professional maintenance to keep the warranty valid. Scheduling a yearly tune-up ensures you remain compliant, protecting you from footing the entire bill if a major covered component fails.
Our Comprehensive Furnace Tune-Up Checklist
Piggies Air Conditioning believes in transparency and thoroughness. Our furnace tune-up is not a quick visual scan; it’s a detailed, multi-point inspection and calibration process that covers every critical aspect of your heating system. Our San Marino technicians follow a meticulous maintenance checklist to ensure nothing is overlooked.
System Inspection and Cleaning:
- Inspect and Clean Burner Assembly: We ensure the burner is clean and igniting properly for efficient fuel combustion.
- Examine the Heat Exchanger: A critical safety check where we look for cracks or corrosion that could lead to carbon monoxide leaks.
- Clean and Inspect Blower Components: We remove dust and debris from the blower wheel and motor to ensure proper airflow and efficiency.
- Clean or Replace Air Filter: A clean filter is essential for healthy indoor air quality and preventing strain on your system.
- Inspect and Clean the Flame Sensor: A dirty flame sensor can cause the furnace to shut down unexpectedly. We clean it to ensure reliable operation.
Safety and Component Checks:
- Test for Carbon Monoxide: We perform a comprehensive test to ensure your system is operating safely and not producing harmful gases.
- Inspect All Electrical Connections: We tighten and secure all wiring to prevent electrical shorts and improve system reliability.
- Test Safety and Limit Switches: We verify that all safety controls are functioning correctly to protect your system from overheating.
- Calibrate the Thermostat: We ensure your thermostat is reading the room temperature correctly and communicating properly with the furnace.
- Inspect Gas Lines and Test Gas Pressure: We check for leaks and adjust the gas pressure to factory specifications for safe and efficient operation.
Performance and Efficiency Adjustments:
- Lubricate All Moving Parts: We apply lubrication to motors and bearings to reduce friction, noise, and energy use.
- Check and Test the Ignition System: Whether you have a pilot light or electronic ignition, we ensure it’s working reliably.
- Monitor the Startup and Shutdown Cycles: We watch the furnace run through a full cycle to confirm smooth and proper operation.
- Measure Blower Motor Amperage and Voltage: We verify that the motor is operating within the manufacturer’s specifications to prevent premature failure.
When we are finished, we provide you with a detailed report of our findings, explaining the condition of your furnace and recommending any necessary repairs to keep it running smoothly.

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.

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.
