When your furnace is having problems operating, it may be showing signs of strain. Being able to identify these problems early is the best way to stay ahead of them and prevent a total furnace breakdown or lasting damage. Just give us a call when your furnace won’t turn on in Crystal Lake.

We can visit your home for a service appointment and get down to the root of the problem. Keep reading to learn everything you need to know about the signs of furnace problems so you can get them fixed sooner rather than later. For more urgent situations, here’s everything about emergency furnace repair services.

When should you install a new furnace instead of repairing the old one?

  • Age & efficiency drop – if your furnace is over 15–20 years old and running inefficiently, replacement often makes more sense than repair.
  • Repeated repair costs – if you’re paying for frequent fixes (ignition failures, blower issues, burner problems), a new unit can be more economical long term.
  • Inadequate heating despite repairs – if repairs still can’t restore proper heat output, a new furnace may be needed.
  • Safety & reliability concerns – persistent malfunctions, carbon monoxide risk, or breakdowns during cold seasons justify a new installation.
  • Modern features & warranty benefits – a new gas furnace or high‑efficiency model often comes with better warranties, lower energy costs, and improved controls.

3 Easy Ways to Boost Furnace Efficiency

Your furnace has a base energy efficiency rating, but there are always steps that you can take to get a little extra efficiency boost. And let’s face it, every little bit that you can save on heating your home this winter will add up.

When considering a new furnace or upgrading your heating system, understanding efficiency AFUE ratings can help you choose a model that will keep your home comfortable while saving on energy bills. Before making a decision, it’s important to evaluate your current budget and assess your current system to determine what makes the most sense for your needs.

If you decide to invest in a high efficiency unit, be sure to look into available financing options to help manage the upfront expense, and consider installation costs, which can vary depending on the type of system you choose. Financing options may offer homeowners the opportunity to pay for their furnace system over time while reaping monthly energy cost savings. Scheduling a tune-up for your existing system can also help avoid extra costs and fewer repairs, ensuring your furnace operates efficiently while you plan for an upgrade.

Give us a call whenever you need furnace service in Oak Brook, IL. You can also keep reading to learn about a few of the ways that you can help boost heater efficiency and potentially save some money on energy costs while also lessening the wear and tear on your unit. If you’re already noticing warning signs, these furnace issues deserve quick attention.

How can upgrading to a new furnace improve energy efficiency?

  • A new high‑efficiency furnace will have a better AFUE (Annual Fuel Utilization Efficiency) rating, converting more fuel into usable heat and reducing waste.
  • Modern furnaces often include variable speed or two‑stage operation, which adapts output to demand and reduces energy overrun.
  • Upgrading insulation, sealing leaks, and optimizing ductwork paired with a new installation lets you get more from your system.

Introduction to Furnace Efficiency

Furnace efficiency plays a major role in how much energy your home uses and how much you spend on heating costs each winter. The key measurement to look for is the Annual Fuel Utilization Efficiency (AFUE) rating, which tells you how effectively a furnace converts fuel into usable heat. For example, a high efficiency furnace with a 95% AFUE rating means that 95% of the fuel is turned into heat for your home, while only 5% is lost. On the other hand, a furnace with an 80% AFUE rating loses 20% of heat energy as inefficiency. The higher the AFUE rating, the less energy and money you waste. The minimum AFUE rating for furnaces is 80%, which means even the least efficient models must meet this standard. When considering a new furnace or upgrading your heating system, understanding efficiency AFUE ratings can help you choose a model that will keep your home comfortable while saving on energy bills. Investing in a high efficiency unit not only reduces your fuel bills but also helps your heating system last longer and perform better throughout the season.

Types of Furnaces

When it comes to choosing a furnace, there are several types to consider, each with its own features and efficiency levels. Natural gas furnaces are among the most popular due to their reliability and cost-effectiveness, but propane and electric furnaces are also common options. High efficiency furnaces, such as condensing furnaces, use a second heat exchanger to capture more heat from exhaust gases, making them much more efficient than standard models. Systems with higher AFUE ratings are usually condensing furnaces, which are designed to maximize energy efficiency. A high-efficiency gas furnace can have an AFUE rating as high as 98.5%, making it one of the most efficient options available. Gas furnaces are available in single stage, two stage, and variable speed designs, each offering different levels of comfort and energy savings. Single stage furnaces operate at full blast whenever they’re on, while two stage and variable speed models can adjust their output to better match your home’s heating needs, improving efficiency and comfort. Understanding these options can help you select the right furnace for your home, whether you’re looking for a new furnace or upgrading your existing system.
