Most people don’t put much thought into their furnace until there is an issue. Even if you get regular furnace maintenance performed by Lamco Systems, no furnace is going to last forever. So how do you know it’s time to replace that old furnace? Here are the factors you need to consider when determining whether or not you need a new furnace.

Frequent furnace repairs

We love seeing our customers, but have you been seeing our faces too often? It’s normal for a heater to need some attention once a year or so, but if your unit is well-maintained, it shouldn’t need frequent repairs. If you are calling us about the same problem over and over again or you find that you need several visits in one season, it may be time for a new furnace. A good rule of thumb to use is if your annual furnace repair costs are more than half of the current value of your unit, it’s time to replace it with a new model.

Skyrocketing energy bills

Do you find that you are paying higher energy costs that you did at this same time last year? This is a sign that your furnace is not working as well as it did before. You can often have your energy company perform an audit for you so you can assess how you can remedy your escalating energy bills. It can also help you determine if it is time for a new unit. Additionally, if you upgrade to a high-efficiency furnace, you may quality for tax credits or utility incentives, which can help you pay for a new system.


Like everything else, furnaces don’t last forever. If your unit is older than 15 years old, it is time for a new one. Even if your furnace is not quite that old yet, keep in mind that older units run less efficiently than newer units. If you replace your furnace is an energy-efficient model, you could see a 30 percent increase in efficiency.

Excessive noisiness

If you find that your heating unit is clanging, banging, clinking, and squeaking so loudly that you can’t hear yourself talk, it could be an indication that you need a new unit. It may be something as simple as a belt replacement or a part coming loose; however, you will need a professional to come and determine that. The new units on the market are virtually soundless, so if the noise pollution of your heater is getting you down, it may be time for a new unit.
