Considering Replacement ?

When you think about it, the furnace is one of the most important parts of your home. It provides heat and keeps us warm during these cold winter months. But just like anything else, furnaces can wear down over time and eventually need to be replaced. So how do you know when its time to replace yours?

Furnace Is Near The End Of It's Service Life

Most furnaces are expected to live and work properly for around 15 years. Of course, this all depends on how you’ve maintained it and the climate you live in. When they get close to that mark you will notice that they start working worse and worse. Continuing to use a furnace for more than 15 years may result in a threat.

Furnace Needs Frequent Repairs

When your furnace gets close to ending its life expectancy it will break down more often than it used to. At this point, it might be more financially advantageous for you to simply install a new furnace than to keep fixing the old one.

Should I repair or replace my furnace

repair vs replacement

Assess Cost Of Repair Vs The Cost Of Replacement

Try to take some notes every time your furnace breaks down. How much does every fixing end up costing you? Add it all up. If the added repairs cost more than 30 or 40 percent of the replacement cost, you need a new gas furnace.

Heating Bills Start Going Up

If you notice this happening out of the blue, than there’s something wrong with your heating system. Given the fact that it’s old or maybe broken, the furnace may be surprisingly inefficient. Therefore, go back to the drawing board, do some more math and try to see how much money you’re spending now versus how much you could be saving if you installed a new one.

Furnace Doesn’t Warm Up Your House Sufficiently

Old furnaces that are close to breaking down completely are not able to warm a space or an entire house like they used to. If you notice this happening to your living space, your furnace needs to be pulled out of circulation.

When The Quality Of The Air Indoors Is Poor

If this happens, you need to be on your guard because poor air quality indoors and bad ventilation can lead to mold and, later on to respiratory problems and even asthma. The first sign that something is wrong will be an unpleasant smell coming from the vents.

 Furnace Is Too Noisy

Yes, a noisy furnace is a nuisance. But it doesn’t just bother your day to day life, it can also be a sign that you have a serious problem. Depending on the different sounds it makes, the furnace may have an unbalanced blower wheel, the interior fan might have broken or there might be something wrong with the transformer if you’re hearing a humming.

If You’re Planning On Selling Your House

Let’s say that you plan on moving away and selling your house in the next few years. If you have an old furnace that is close to its life expectancy, you should replace it. This is an excellent way to improve the value of your property.

Furnace Is Emitting Carbon Monoxide

A furnace that is emitting carbon monoxide is highly dangerous. Old furnaces sometimes get cracks inside the heat exchanger. Therefore, carbon monoxide can leak through there without you knowing. If you start getting frequent headaches, feel nauseated, or feel like your eyes and nose are burning, this might be the cause.

You know what time it is! Call your licensed HVAC contractor! He/She is the only one able to perform a heating system inspection and determine what problems it has. Are you also worried about your heating bills being too high? This is a great topic of conversation as well! Learn the red flags that indicate that your HVAC unit may need maintenance, a repair, or possibly it may be time to get it replaced.

Mr. Zhang was very informative. He explained in terms I could understand just what the problem was and what we could do to correct it. Rather than repair I decided to replace. I wasn't charged a penny more than the price he quoted me. I'm very pleased with the work .

Hot Questions:

Are old furnaces dangerous?

The most dangerous hazard of an old gas furnace is carbon monoxide poisoning. An odorless and colorless gas, carbon monoxide can cause nausea and dizziness, and even death. 

Should I replace my 25 year old furnace?

Gas furnaces have a life expectancy of 15- 20 years. However, when your unit is close to the end, a heating system replacement always comes with very clear signs. Here they are now:

· Your utility bills have spiked
· Repairs have been more frequent than normal
· The temperature in your house is not consistent
· The heating unit is more than 20 years old


Even if your furnace is still chugging along, it may be time replace it before it breaks at the most inconvenient time. Give us a call right now and book a free session with SuperTech! Let’s see what’s wrong!

Can I replace my furnace on my own 

Absolutely not. Even if you do find tutorials and videos online that walk you through the process, you should always remember that your furnace is a dangerous appliance that runs on gas. Any mishap or mistake that you make can have dire consequences. Remember that HVAC appliances use toxic refrigerants and an entire plethora of chemicals to work that you are not used to. If handled incorrectly, they can leak and harm you.


Apart from that, HVAC appliances use high voltage to function that might shock you or result in sparks. For your safety and that of your family, call a specialist. We are always happy to help you if you need assistance and we are only a phone call away!
Furnace replacement needs a lot of expertise and planning so that it can be carried out perfectly and safely. Living with an old furnace that ups your heating bills and spoils the air quality in your house should never be an option, so think about any other questions you might have and let us know!

Should I Replace My furnace and air conditioner at the same time 

You may as well go ahead and replace your furnace too if it’s older than 10 years. They usually share a blower motor and, if one is upgraded or replaced and the other is not, the system won't work correctly. Plus you can save money by getting both jobs done at once!

How much does it cost to replace furnace 

Of course, as you might have expected, there is no way of telling exactly what it will cost you to replace your old furnace until you give us a call. The whole service usually depends on the type of furnace you choose to install and the brand you want. The good news is our prices are competitive and we have the best offers!
