As temperatures drop, your furnace becomes the unsung hero of your home, keeping you warm and cozy. But like any hardworking appliance, furnaces don’t last forever. Ignoring signs of wear and tear can lead to unexpected breakdowns and costly repairs when you need heat the most.
At G1 Air, we’ve been helping San Antonio homeowners stay comfortable since 2017.
In this blog, we’ll walk you through the key signs that indicate it might be time to replace your furnace, so you can avoid the stress of being left in the cold.
It’s Surpassed Its Expected Lifespan
The most common reason that home and business owners choose to replace their furnaces is due to age. The average lifespan of a furnace is between 15 and 20 years, depending on the amount of usage and dedication to maintenance. If your furnace has reached or surpassed its expected lifespan, consider replacing your heating system.
You’re Experiencing Frequent Repairs
As your furnace reaches the end of its lifespan, you can expect to encounter more frequent repairs. Furnace repairs can cost hundreds of dollars, and over time, these repair bills may not be worth it financially. If your furnace is more than 15 to 20 years old and repairs are becoming more and more frequent, replacing your furnace may be the most cost-effective option.
The House Heats Unevenly or Has Cold Spots
If you’re noticing that some rooms in your home are colder than others, or that your furnace isn’t heating enough to keep the whole house warm, a new furnace may solve the problem. There are several reasons why you may be experiencing uneven heating, such as a furnace that’s not powerful enough for the home’s size or a furnace that’s on its last leg.
In some instances, uneven heating in a home can be due to the type of system you have. G1 Air offers convenient temperature zoning control systems that allow you to have individual climate controls in different areas of the house. Not only does it make each area more comfortable, but temperature control can also save you money by having the heat higher or lower in certain zones.
Your Heating Bills are Significantly Rising
Your furnace works by burning fuel, such as propane gas or heating oil. Ideally, all of the gas used by the furnace should go toward producing heat for your home or business. However, this isn’t always the case. When a furnace stops functioning properly, it requires more energy to heat your home. If you’re noticing a sudden shift in your energy costs, it may be time for a furnace inspection to determine the underlying cause.
There are Humidity Problems in the Home
Humidity levels that are too high or low in the home are a common concern for property owners. Not only can humidity be uncomfortable, but can also cause damage to your home, especially if you have wood floors. Very humid conditions in a home also pose a mold risk, which can contribute to respiratory illnesses. Newer furnaces are often better equipped to deal with humidity concerns compared to outdated models.
You Hear Odd Noises or Long Periods of Silence
Modern furnaces are designed to be relatively quiet to avoid disturbing residents. If you notice that your heating system is making unusual noises, such as screeching, squealing, rumbling, rattling, or grinding, it may be due to a leak, crack, or other problem within your furnace. Extended periods of silence can also be a cause for concern and may signal that something is amiss with your system.
Air Quality Is Starting to Deteriorate
Air quality is essential for all homes and businesses to prevent health complications. The furnace is responsible for delivering good air quality in your living spaces, and if you notice a lot of dirt, dust, soot, or dander around, it could mean that your heating system is not doing its job. Cleaning your air filter is the first step toward achieving better indoor air quality. However, if maintenance doesn’t fix the issue, you may need a new furnace.
Yellow Burner Flame in the Furnace
Most people don’t pay attention to the color of their pilot light but examining this flame could tell you a lot about the state of your heating system. If the flame is yellow, it could mean that gas isn’t burning off completely and your furnace isn’t heating to its full potential. A yellow flame could also mean that your furnace is producing carbon monoxide (CO), which can be dangerous to the health and safety of your family.

Visible Rust or Cracks In or Around the System
It may be time to replace your old furnace if you notice rust or cracks developing. It’s not uncommon to find rust or corrosion in areas where the metal is exposed to combustion gases, but over time this rust can weaken the structure of the unit. Without repair, rust can break down into cracks which require prompt repair to prevent leaks and other hazardous situations.
Your Furnace Isn’t Cycling Normally
Furnaces go through a cycle of turning on and off during normal operation. You can expect the furnace to kick on when the thermostat drops down below the set temperature. Once the home reaches the set temperature, the furnace will turn off. If you find that your furnace is cycling on and off frequently, or that your furnace seems to be running all the time, it’s usually a sign that the unit is not working correctly.
