Thank you for checking back on the blog for Premier Heating and Air, Denver’s leader in HVAC and air conditioning repair. With the changing seasons, it is time to get your HVAC checked to ensure that it is ready for the cold season. Invariably, our clients are able to save money by having their HVAC maintained on a biannual basis, generally in the spring and fall, which helps us find potential problems and center which can be fixed for less. If they are ignored, the problems could affect other systems and parts within your HVAC. An HVAC that is not serviced on a regular basis, generally, ends up needing a more serious furnace repair than its regularly maintained counterpart. Contact us to arrange for a service agreement or a no-risk, free estimate.

On our blog, we like to answer questions that we get from our customers and from the general public in our HVAC advice column.

Dear HVAC Experts,

I have started to hear some rattling noises from our HVAC that I have not previously  heard. This has me a little concerned because our HVAC is getting up there in years. It is the same HVAC system that was in the house when we bought it 15 years ago, and from the paperwork I was able to dig up, it looks like it was about 5 years old then. My fear is that our furnace is on its last leg.  How long do furnaces generally last? I just want to know if a 20 year old furnace is considered old or if it has some life left in it. Thank you in advance for answering my question.

Dear Wondering,

You are very smart to ask about new noises you are hearing from your HVAC. To often, we hear of people who ignored what sounded like minor rattling or humming coming from their HVAC, furnace, or air conditioner. There is a reason that you hear a new noise in your HVAC. Something has changed and probably not for the better. We also key in on a new smell coming from the furnace or HVAC. To have one of our NATE certified technicians take a look at your HVAC, Simply fill out our free estimate form.

Thank you for also asking about the life expectancy of a furnace. Although it’s not unusual to see systems that have lasted 20 to 30 years, most furnaces last about 15 years while air conditioners last about 10 years on average. So you are already on the plus side of your furnace if it has been around for 20 years. Now, that doesn’t mean go out and buy another furnace tomorrow.  We can successfully extend the life of an older furnace with regular maintenance. So, before you order a furnace replacement, let’s try to catch the furnace repairs in their infancy so your HVAC can get back to running smoothly. Contact us to schedule a free estimate for your furnace repair and set up a service agreement. Thank you for writing into our HVAC advice column, and we hope that this entry was informative.
