How Long Does A Gas Furnace Last in Savannah, GA?

Your furnace plays a crucial role in keeping your home cozy throughout the colder months. However, over time, you may notice a decline in its efficiency. This often raises the question, “How long can a gas furnace last?

At Galbreath Heating & Air, based in Savannah, Georgia, we aim to help homeowners understand the various factors that influence a furnace’s lifespan. By doing so, you can take proactive steps to maximize its performance and determine when it might be time for a replacement.

Typical Gas Furnace Lifespan

On average, gas furnaces have a lifespan of 10 to 15 years, though some may last longer with the right care. While it’s rare, a well-maintained furnace could function for up to 30 years. Understanding what impacts its longevity will help you ensure your system remains efficient for as long as possible.

Key Factors That Affect Furnace Lifespan

Several factors contribute to how long your furnace will last:

  • Correct Furnace Size: Choosing the right size furnace for your home is crucial. If it’s too small, it will overwork to keep your home warm, which reduces its lifespan. Conversely, an oversized furnace may cycle too frequently, causing wear and tear on its components.
  • Make and Model: The specific brand and model of your furnace also matter. Newer systems often come with advanced features designed to enhance energy efficiency and extend the furnace’s life.
  • Installation Quality: The way your furnace is installed can greatly influence its performance. Poor installation can lead to operational issues and a shorter lifespan. At Galbreath Heating & Air, we ensure proper installation to help you get the most out of your heating system.
  • Humidity and Ventilation: High humidity levels can lead to rust and damage to your furnace. In humid environments like Savannah, maintaining good ventilation and controlling moisture levels can prevent premature deterioration of the system.
  • Condition of Ductwork: Your home’s ductwork plays a critical role in how efficiently your furnace operates. If the ductwork leaks or is poorly designed, heated air can escape, causing your furnace to work harder and reducing its lifespan.
  • Regular Maintenance: Consistent maintenance is key to prolonging your furnace’s life. Professional tune-ups can help identify and fix minor issues before they turn into major problems. At Galbreath Heating & Air, we offer regular maintenance services to keep your system running smoothly all year long.

How to Extend Your Furnace’s Lifespan

While some factors are out of your control, there are a few things you can do to ensure your furnace lasts as long as possible:

  • Hire Qualified Technicians for Installation: A proper installation is essential for optimal performance. Rely on professionals like the team at Galbreath Heating & Air to ensure the job is done right.
  • Upgrade to a Modern, Energy-Efficient Furnace: If you’re thinking about replacing your furnace, consider upgrading to a more energy-efficient model. Modern furnaces are designed to last longer and use less energy, reducing your overall costs in the long term.
  • Control Indoor Humidity: Controlling moisture in your home can prevent damage to your furnace. Using a dehumidifier or adjusting your AC can help lower humidity levels, protecting your system from rust and corrosion.
  • Schedule Annual Maintenance: Regular maintenance is the most effective way to extend the life of your furnace. Annual tune-ups ensure your system is running efficiently, no matter the season.
  • Use the Furnace Wisely: Being mindful of how often you run your furnace can also help prolong its life. Set your thermostat lower when you’re away, and avoid overworking your system by using extra blankets at night.
  • Replace Air Filters Regularly: Clean air filters are vital for ensuring proper airflow and preventing system strain. Dirty filters can cause your furnace to overheat, leading to potential damage. Make sure to replace air filters regularly for optimal performance.

When It’s Time to Replace Your Furnace

Even with proper care, furnaces don’t last forever. Here are some signs that it may be time to consider a replacement:

  • Your system is over 15 years old and requires frequent repairs.
  • The cost of repairs is more than half the price of a new system.
  • You hear unusual noises or notice strange odors during operation.
  • Your furnace cycles inconsistently or your energy bills have increased without explanation.
  • You experience uneven temperatures throughout your home.

Received excellent service from technicians and office staff .
My technician/salesperson was extremely knowledgeable. The product came highly recommended from individuals that I trust. I also found the salesperson showed me my options without trying to sell me more than I need. Prices are competitive.
They were very professional, fast response, showed up when they said they would. Very reliable.
I had a minor emergency involving a leak in my A/C unit. Galbreath was extremely responsive, polite, and professional. They kept me updated with texts and I very much appreciated the fact that they sent me information about and a photo of the technician coming to perform the service. The technician, James, was very personable and explained everything that he did. I would highly recommend this company.
Excellent as always. Technician Gil was friendly, professional and helpful about passing on tips to me. Glad i got to meet the young man
I highly recommend Galbreath Heating and Air for PROFESSIONAL QUALITY service for your HVAC SYSTEM. When Aaron Pitts (technician extraordinaire) arrived, he went stem to stern diagnosing an ongoing issue, he explained everything, he made valuable recommendations, offering great advice and most importantly, gave me piece of mind. From here on out, they are my "go to" company. Thank you, Aaron, you are an asset to your company.
I called yesterday afternoon after hours and got a call back the next morning and got an appointment immediately had someone at my house within an hour. Kevin came and did a great job on my unit and replaced my thermostat and did a full work up on my HVAC system fast and efficiently and explained everything to me in a very digestible and understandable way.

James was great, explained everything in detail. Arrived early which was great, now I have the rest of my day!
Very responsive and professional!
We obtained 3 quotes for a full system and ductwork replacement. They were all around the same price but Galbreath stood out from the amount of detail and effort our sales rep Tyler put into the quote. I also liked that Tyler was going to be our project manager throughout the project, and ended up doing an excellent job from start to finish to ensure all my questions and concerns were addressed.

It was the right decision as the install team (Charlie, Tim and Brandon) did a phenomenal job over three days. We moved our outdoor unit to another location and moved our air handler to the attic, so it was a large project that was very well executed. Highly recommend Galbreath for your HVAC needs.
Good.
Had to replace 18yr old system that died on the hottest week in May. Tyler was awesome and fit us in on his way home so we could get the air flowing sooner rather than later. Techs came and spent a hot miserable day installing our new system. Very professional and respectful of our property, cleaned up after themselves. Highly recommend.
Great service, technician was very knowledgeable and showed me exactly what was wrong.
Kevin Jackson was very professional and knowledgeable of my two units. He took his time and shared with me his findings via pictures of what he found and what he did.
My AC was not working properly, and attempts to use our home warranty was a total failure. So I called Galbreath as I have used them throughout the years successfully and today was no different. From amazing customer service and easy next day scheduling.They were even able to come the same day as time opened up with one of the technicians finishing early. Kevin the technician, throughly explained everything, showing me detailed pictures which I appreciated. After almost 3 weeks, there is AC. It is worth having quality, professional services you can count on.
Technician was great, very professional and knew his business. Highly recommended.
Giving these guys another 5 star review ...! They came within 2 hours for an emergency call and replaced a part fairly and honestly in Pooler, GA! I like working with locally owned companies for this reason!
The scheduled technician was timely, polite and professional. Did his tune-up services and no issues to report as of the noting of this memo.
Tim did a fantastic job. Modified return system, single point filter and UV light. System running better than ever.
Respectful, clean, and hard working. Did a fantastic job.
Great service
Gil was very knowledgeable and professional. Gil is the reason I will be returning to you all for any HVAC needs, he was awesome, got an easy fix, and educated in the process.

Great service! James was on time, detailed oriented, completed tasks as promised and went beyond requirements to be sure my needs were met.
Galbreath just put in a new Lennox system in my home. It was a great experience from the estimate process to the installation.
Gill just finished his service call with us. Throughout the years, he has always been a true professional. I enjoyed our time talking and learning from Gill. He should be recognized as a true asset of Galbreath. He is the face of Galbreath as an extremely knowledgeable Technician. Thank once again for your friendly service.

Outstanding customer support, and excellent service from Kevin Galbreath Heating & Air technician. Kevin is an outstanding technician and answered all my questions, and performed the maintenance on my AC that was not rushed, and he took his time. He also scheduled a follow-up appointment in a timely manner. Galbreath Heating & Air have serviced my ACs for over 10 years and they stand-by their work.
Very happy with the free consultation for duct work that I received from this company. They do high quality work and are honest in their assessments. The technician provided a great deal of information to me to help with our situation and provided personal contacts for realtors. It’s refreshing to find a company that looks out for the best interest of their client no matter what. Highly recommend them

Great company to work with, and attentive to any issues even over a year since installation of my entirely new systen. Woukd highly recommend.
Brandon was great. Very polite and explained everything in full as he was performing each group of tasks. Biggest thing to me was I felt that everything done was to improve the performance of my Goodman A/C, assuring lower electric costs and more pure air to breathe. Thank you.
We had Galbreath install a whole new system of heating and cooling with 3 zones 2+ years ago in a home we had purchased. We are extremely happy with the unit and the service they have provided. They care about what they install and I know if we do have any issues with the unit they will take care of it promptly.
