How Long Do Furnaces Last?

Installing a furnace from a quality manufacturer is an investment in long-term home comfort. Modern furnaces have durability that outstrips models from only a few decades past. Furnaces often outlast more technologically sophisticated home comfort systems like heat pumps. However, if you’re either looking into installing a furnace or concerned about the one already installed in your home, you’ve probably wondered how long it is supposed to last.

There is no single answer to that, although there are generalizations. The important thing to know as we go forward is that furnaces can only expect to reach their fullest service if they receive regular repairs and maintenance: a neglected furnace might only creak out a few years before it needs replacement.

Rely on professional companies like Goettl Good Guys Air Conditioning when you need service on your furnace in Benson, AZ. We’ve been a household name in comfort since 1939.

The lifespan of a furnace

Today, the average service lifetime of a furnace is between 16 and 20 years. This is a major improvement over older models, which usually made it to 10 years but not much beyond. It isn’t surprising any more in the HVAC business for technicians to encounter furnaces that have been in service for over 20 years.

However, we should caution people that if a furnace does manage to surpass the 20-year mark, it should probably be replaced soon. Once a furnace that old starts to malfunction, it will quickly cost more to repair than to install a new system. Consult with a professional the next time you call for repairs on a very old furnace to see what your best option is.

For younger furnaces, make sure that you call for repairs the moment you sense something is wrong. The sooner you have fixes done, the better it is for your furnace as a whole: malfunctions tend to trigger more malfunctions, and they make the furnace work harder and age faster.

Also make certain that you enroll in a regular maintenance program from a dependable HVAC company. The furnaces that reach the 20-year milepost and beyond get there because their owners made sure the system received professional care on a regular basis. A good preventive maintenance program will provide you with a tune-up each year for your heater (and one for your air conditioner).

At Goettl Good Guys Air Conditioning, we want you to get the most out of the comfort system in your home, no matter the weather outside. Although a Benson, AZ furnace might not see as much use as one in North Dakota, it still needs repairs and maintenance from a trusted contractor for it to reach its fullest lifespan.

My technician Jorge (George) Gutierrez was out today performing the a/c system check. He did a fabulous job and identified significant issues and concerns for the longevity of my current 12 year old system. He was very knowledgeable and helpful on what my options are and in the end I’ll be getting a new system instead of worrying about the current system failing in our extremely hot temperatures. He was very respectful of my home and my dog was ecstatic to meet him.

Frank identified the need for new faucets in the master bath and discussed my preferences. The type of faucet being replaced is no longer available (mini wide spread) so he had to do some research to come up with a solution. Had to be ordered, not surprisingly, and we appreciate his conscientious performance.

This was my first service with this company and it was a pleasant one. The technicians were professional and polite and quickly resolved a minor scheduling conflict. Interaction with a sales manager for a quote on needed equipment was equally pleasant.

Signed up for the Sadie membership as a a preventative measure to avoid bigger problems down the line. Had my appointment to check my system today and to my surprise the tech discovered a huge gash in my ductwork! Thankfully so because the ductwork up there is a very tight space which I could never squeeze myself into and would’ve gone unnoticed for who knows how long. Huge thank you to Technician Roy Adame for making the trip out on a Saturday afternoon, going the extra mile to fully inspect the system in a tight space, and fully explaining the possible causes of the damage and the impact it would on the system performance. 🙏🏼🤙🏼🫡👏🏼🙂
