Mastering Furnace Maintenance: A Comprehensive DIY Guide

At Goettl, trust and expertise are the cornerstones of our reputation. With years of experience in heating systems, our customers have come to depend on our in-depth knowledge, transparent communication, and unwavering commitment to their satisfaction. In this comprehensive DIY guide to furnace maintenance, we share some of the industry secrets that have made us a go-to resource for heating solutions. 

Your Filter Is Your Friend

Your furnace filter is like your personal superhero, diligently defending your heating system from the relentless onslaught of dust, allergens, and airborne particles. A clean filter is not only your ally in maintaining indoor air quality, ensuring you breathe easier, but it also plays a pivotal role in the longevity and efficiency of your furnace. We recommend changing your filter every 30 to 90 days, depending on usage and the type of filter you have. 

This simple yet essential task not only keeps your furnace running smoothly but also conserves energy, reducing your utility bills and environmental footprint. Embrace the power of regular filter maintenance—it’s a small task with enormous benefits! 

A Clean Space Is A Happy Space

Maintaining a clean and clutter-free environment around your furnace is not just about aesthetics; it’s a critical aspect of ensuring the safe and efficient operation of your heating system. When you give your furnace the space it needs, it can breathe freely, allowing for optimal airflow and combustion. 

Additionally, a tidy furnace area significantly reduces the risk of accidental fires. Clutter, especially flammable materials, or chemicals stored nearby, can pose a serious hazard. By keeping the surroundings clear and free from obstructions, you’re enhancing the overall safety of your home. It’s a simple yet impactful step in safeguarding both your family and your furnace’s performance. 

Keep An Eye on the Flame

A healthy furnace flame is not just a visual detail; it’s a crucial indicator of your heating system’s well-being. A properly functioning furnace should produce a steady, blue flame. This blue flame signifies efficient combustion, which maximizes the heating output while minimizing emissions. 

However, if you observe a yellow or flickering flame, it could be a telltale sign of underlying issues with your gas mixture or venting. A yellow flame often indicates incomplete combustion, resulting in energy wastage and potentially dangerous carbon monoxide production. This color change may also be related to problems with your furnace’s ventilation, such as blockages or improper airflow. 

In situations where you encounter a yellow or flickering flame, it’s crucial to prioritize safety. We highly recommend contacting professionals with expertise to diagnose and address such issues promptly, ensuring your furnace operates safely and efficiently.

Thermostat Check-Up

A misbehaving thermostat can sometimes be the cause of furnace issues. Make sure your thermostat is set correctly and functioning well. If it’s acting up, try changing the batteries or resetting it according to the manufacturer’s instructions. 

Remember, your thermostat is the command center of your heating system, and even minor issues with it can lead to discomfort and inefficiency. By ensuring it’s in good working order, you’re taking a significant step toward maintaining a comfortable and energy-efficient home. 

Regular Check-Ups by Pros

Remember, while some furnace maintenance can be done at home, more serious repairs should always be left to the pros. Even with the best of DIY care, furnaces appreciate a professional touch. Regular maintenance by experts can identify potential issues early, keep your furnace in top shape, and ensure you stay cozy all year round. 

don’t wait until winter chills set in!

2.7.24Jay Cruz, technician, arrived on time today to service/check my ac/heating. Jay arrived timely and was friendly. Jay checked my inside unit, ceiling vents, etc and he made some recommendations. He was easy to talk to and very professional. He will be sending me an email with the recommendations and costs associated so that I can save the money to have these taken care of. I will say, no other technician has been as proficient as Jay.Yesterday, 2.6.24, I received a call from Betty. Betty was also very friendly, professional and knowledgeable. She listened to me and made recommendations and advice. By the end if the call, I felt like Betty was a friend.Thank you to Jay and Betty!Late one evening I was washing clothes. Daughter noticed water on floor under washer. I was so upset and worried about finding someone to fix the problem, whatever it was, and especially the cost. Goettl this the rescue! Namely, their employee/plumber, Chris! The next day, Chris came, found the clog in my pipes, and…voilà! We joined their $14.95 per month plan and that was all we paid for a job well done! Thank you!3.26.24Tyler Leija was great! He checked my drain pipe outside with a camera. Advised everything was clear. He checked my kitchen and master bathroom sinks and toilet.

Roy A. was a pleasure to work with. He thoroughly and expertly explained all of the issues with my system with pictures and videos. He was transparent about the remediation options available to me and patiently reviewed each option with me. The install team, Daniel and Roy, were equally as awesome. They too were extremely knowledgeable, patient with my questions, and worked diligently to get my new unit up and running safely in one day. I couldn’t have asked for a better team.
