4 Signs You Need a New Furnace

Year in and year out we get to the cold months and rely heavily on our furnaces. When you crank up the heat up, it’s normal to expect the furnace to kick on and send warm air into your home. What happens, though, when the heater doesn’t work as you would expect it to? Repair bills are going to roll in, and you may start to question whether you should replace the furnace entirely, or try to continue with what you have. We’re here to shed some light on the topic to help you identify signs that it’s time for a replacement.

The Age of the Furnace

One of the biggest signs that your furnace needs to be replaced has to do with the age of it.  A high-efficiency and quality furnace is going to usually last you around 10 to 20 years as a rule of thumb. Once you get past that 20-year mark especially, you want to be thinking about a replacement.

It may not even be that the furnace no longer works. What happens is that as a furnace age, the energy efficiency level that it has is going to be reduced. Technology is also going to move forward with new efficient units being put out onto the market. The cost to run the aging furnace even if it does function still, may not be worth it compared to the price to just replace it.


What is the AFUE Rating?

The AFUE rating is the score that your furnace is going to get about its energy efficiency. What is the rating of your system at? Is it above or below a score of 90? When you are below 90, new units are certainly going to be able to run more efficiently for you, using less energy to function. Once you get below 90, or especially below a score of 80, you want to be thinking about investing in a replacement. An older furnace with a lower AFUE rating is going to be a drain on resources to continue to run regularly. The initial cost to replace it may seem a bit steep at the moment, but the long-term benefits are noteworthy.


The Health of Your Home

What is the state of the health of your pets and family inside of the home? When you have an aging furnace, what you may find is that it is not creating quality air flow as it used to lead you to develop illnesses more often. If you have respiratory problems, this is only going to be exaggerated even further by an aging furnace. Always put your health first when it comes to this and refer to our HVAC Jacksonville FL for guidance.


Change Your Batteries

It’s also a good idea to check and maintain your smoke alarms and carbon monoxide detectors on a regular basis. You can do this by pressing the test button (which is most often found on the face of the smoke detector) every thirty to sixty days and changing the batteries twice per year. I always recommend changing alarm batteries on the same days you change the clocks for Daylight Saving Time. Another issue that often goes overlooked is when people use different batteries throughout the home. It’s best to change all of the smoke detector batteries at one time, using the same brand with the same expiration date on the side (yes, batteries have expiration dates, if you didn’t already know that), and preferably from the same package. This is helpful because while a certain brand may last you one amount of time, another brand may only last half as long; leaving you with batteries going out at random intervals.

I will be recommending J&W to my friends and family. They were very professional and on time. Did a very well job in... a quality manner. Dustin, Mark, and Robert. Worked very well together and was in and out with no cleanup for me to do. Thanks so much for getting my home back to a cool environment.read more

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company again.read more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two men.read more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
