Just like nearly every appliance within your Santa Rosa area home, your home’s current furnace, unfortunately, has a limited lifespan and will not work forever. Your home’s furnace will leave some signs behind when it’s beyond repairs and needs to be replaced. To know if you need to replace your current furnace with an existing one, check for signs like:

Furnace is over 15 years old

Typically, furnaces are effective and reliable for about 15 years or so. If your furnace is over the age of 15, its performance will likely begin to dwindle. Repairs might be able to fix its performance in the short-term, but it will likely need frequent repairs in order to functionally heat your home. The better option for your Santa Rosa area home will likely be to replace the unit with a newer system.

High energy bills

When your home’s furnace is working as it should be, it will be able to efficiently provide proper heating to your home. When it’s not functioning as it should, however, it can stay on longer than usual in an effort to effectively heat your Santa Rosa area home. The longer your heating system stays on, the more energy it will use, causing your energy and utility bills to rise.

Uneven heating

Have you gone through different areas of your Santa Rosa, CA, area home, finding that each room seems to be a different temperature? If so, there is likely an issue with your home’s furnace. The system isn’t doing its job by pushing the necessary heating needed to heat each room evenly.

Uneven heating issues typically occur in older furnace systems. So, while you could choose to have your furnace repaired to temporarily correct the issue, you’ll likely need to replace the unit as a whole to provide a long-term solution to the issue.

Frequent repairs are required

If your furnace has stopped working, and you’ve already had it repaired countless times, you’ll likely need to consider replacing the unit altogether. This will be the only way to ensure that your previous problems don’t keep returning.

Frequent repairs on your HVAC system will result in you pouring money down the drain that could otherwise go toward the purchase of a new system that will not only stay functional for longer, but provide higher efficiency. If you find yourself constantly having to repair your HVAC system, we highly recommend that you replace it with a newer unit.

Furnace is loud or makes rumbling noises

Outside of initially starting up, you shouldn’t notice any loud noises coming from your furnace. If you do hear loud noises coming from the system, there is likely an issue that needs to be resolved. There could be unresolved cracks, leaks, or structural issues that would result in needing to replace your system as soon as possible to avoid a complete breakdown.
