Common Heating Problems We Solve in San Marino
A malfunctioning heater often presents clear warning signs. If you notice any of the following issues, it’s a strong indicator that your system requires professional attention.
- System Won't Turn On: This is one of the most common calls we receive. The cause can range from a simple tripped circuit breaker or incorrect thermostat setting to a more serious issue like a faulty transformer or safety switch.
- Insufficient Heat: If your home never seems to get warm enough, the problem could be a clogged air filter restricting airflow, an undersized system, or leaky ductwork. Our team will identify the source of the inefficiency.
- Strange Noises: Your heating system should operate relatively quietly. Grinding, squealing, or banging sounds often point to mechanical problems, such as a worn-out motor bearing, a loose component, or an issue with the ignition system. Ignoring these noises can lead to more significant damage.
- Unusual Odors: A faint burning smell when you first turn on your furnace for the season can be normal, but a persistent smell of burning plastic, electrical components, or fuel indicates a serious and potentially dangerous problem that requires immediate inspection.
- Frequent Cycling (Short Cycling): When your heater turns on and off in short, frequent bursts, it’s not only inefficient but also puts excessive wear and tear on the components. This is often caused by a malfunctioning thermostat, a clogged filter, or an oversized system.
- Pilot Light is Out or Yellow: For gas furnaces, a pilot light that won't stay lit or burns yellow instead of a crisp blue is a sign of a problem with the thermocouple or inadequate combustion, which could be a safety hazard.
Our Comprehensive Heating Repair Process
We believe in a transparent and thorough approach to every repair call. When you schedule service with us, you can expect a seamless and professional experience from start to finish.
- Thorough Diagnostic Assessment: Our technician arrives equipped with advanced diagnostic tools to perform a comprehensive inspection of your heating system. We don't just fix the symptom; we find the root cause of the failure.
- Clear Explanation and Upfront Estimate: Once the problem has been identified, we will explain the issue to you in clear, understandable terms. We then provide a detailed, upfront estimate for the required repairs. You will have all the information you need to make an informed decision.
- Expert Repair with Quality Parts: Upon your approval, our certified technician will proceed with the repair. We use high-quality, durable parts to ensure a lasting solution and restore your system to peak performance and safety standards.
- System Testing and Verification: After the repair is complete, we don’t just pack up and leave. We thoroughly test your heating system to ensure it is operating correctly, safely, and efficiently. We verify that heat is being distributed evenly and that the thermostat is communicating properly.
Is It Time for a Professional Repair? A Quick Check
Before calling for service, there are a few simple things you can check that might solve the problem:
- Check the Thermostat: Ensure it is set to "heat" and the temperature is set higher than the current room temperature. Check the batteries and replace them if necessary.
- Check the Air Filter: A severely clogged filter can restrict airflow and cause the system to overheat and shut down.
- Check the Power Switch: Most furnaces and air handlers have a power switch that looks like a light switch located on or near the unit. Ensure it is in the "on" position.
- Check the Circuit Breaker: Look for a tripped breaker in your home's main electrical panel and reset it if needed.
If you’ve tried these steps and your heater still isn’t working, it’s time to call in the experts. Attempting complex repairs without the proper training and tools can be dangerous and may cause further damage to your system.

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.

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.
