An unexpected furnace or air conditioner breakdown is frustrating and can lead to serious problems like pipes bursting in the walls or heat-related illness. At G&R Heating and Air, we know how frustrating it can be when that old AC just isn’t cooling the house like it should, or when your furnace dies right before winter, which is why we’re ready, year-round, to help Northern Illinois residents like you with AC and furnace replacement or repairs. We’re here to take care of you and your family, so you can relax knowing your home will be a safe, comfortable temperature, no matter what the weather’s like outside.

Signs Your Furnace or AC Needs Replacement
Here are some things to look for to know when it’s time for furnace and air conditioner replacement.
1) Your heating or cooling system is over 10 years old
If your furnace or air conditioner is over a decade old, now may be the perfect time to replace it. The average lifespan of heating and cooling systems is between 10 and 15 years, depending on how well they’re maintained and how often they’re used. Older HVAC systems degrade over time, becoming less effective as parts wear down.
Older AC systems also use discontinued refrigerant (R-22). This means that repairs will be more expensive, as the cost of parts and sourcing old refrigerant grows over the coming years.
2) You suspect a refrigerant leak
Our dispatch team often receives calls from homeowners looking to have their refrigerant “topped off” or “recharged”. Refrigerant contained within the system should never have to be replaced and should last for the unit’s lifetime. If your system needs refrigerant, it’s leaking somewhere. A leak sealer is a good temporary solution in some cases, but there’s no guarantee it’ll stop the leak completely. You’ll have to continue spending money on an outdated, inefficient system with ongoing problems until the AC is replaced.
3) Your energy bills are climbing
Even if they still run okay, older furnaces and air conditioners are less efficient and will use more energy as they lose effectiveness over the years. This is due to regular wear and tear, as parts break down. A new, modern system will save you money on your energy bills and reduce your home’s environmental impact.
4) Constant or continued breakdowns
If your system keeps breaking down, it might feel like a better option financially to continue repairing it. However, the cost of repairs can add up very quickly if the unit is older and develops problems in several areas. It’s better to upgrade your HVAC now, and stop throwing your money away investing in a system that needs replacement.
5) You want to incorporate modern features into your home
New HVAC systems have features that make your life easier and improve your home’s efficiency. Zoning systems, smart thermostats, air quality control features, and improved energy efficiency give you more convenient home comfort, and the ability to customize your heating and cooling settings to best suit your preferences and your lifestyle.
Understanding the Lifespan of Furnaces and AC Units
Furnaces typically last between 10 to 30 years, and air conditioners have an average lifespan of 15 to 20 years. Maintenance is a big factor in the overall lifespan of your furnace and air conditioner. If they’re well-maintained, you can expect both systems to last, but if you haven’t checked a filter or had a tune-up in years, it might be time for a system inspection. Whether it’s only been a year, or you don’t remember the last time your heating and cooling system had a tune-up, you can call G&R Heating and Air to schedule your judgment-free HVAC tune-up today.
If you’re asking yourself “Should I replace my furnace and AC at the same time?” — the answer depends on how well they’re functioning, and when each was installed. If one is on the way out and they’re both more than 10 years old, you’re better off replacing both at the same time. You’ll save on installation costs, and you’ll ensure the furnace and AC are compatible, with modern features and excellent energy efficiency.
Assessing Energy Efficiency
To understand HVAC energy efficiency, check the system’s Seasonal Energy Efficiency Ration (SEER) number, and look for ENERGY STAR® rated systems. Generally speaking, newer HVACs will almost always be more efficient than older models, but it’s also important that it’s sized appropriately to your home, your ductwork is intact and designed well, and you keep the system well-maintained over the years.
