For many homeowners on the North Shore, keeping a comfortable indoor temperature can be tricky in older houses—especially when ductwork is limited, aging, or nonexistent. Mini-split (ductless) air conditioning systems are often pitched as a modern solution that’s easier to install than whole-home ducted systems. Still, they come with trade-offs that are worth weighing before you choose.

Here are the key pros and cons to consider when evaluating mini-splits for older homes.

Pros: Why mini-splits can fit older North Shore homes

1) Zoning and room-by-room control. Mini-splits typically allow separate temperature control for multiple indoor heads. That can be especially useful in older homes where rooms have uneven sun exposure, different ceiling heights, or inconsistent airflow. Instead of cooling the entire house at once, you can target comfort where it’s needed ... Read more »

Illinois households face a recurring tradeoff: bring in enough outdoor air for health and comfort, or keep heating and cooling costs under control. In many homes, that balance is difficult to maintain with traditional ventilation approaches—particularly when windows are closed for much of the year.

Energy Recovery Ventilators (ERVs) offer an alternative. By moving stale indoor air out and drawing fresh outdoor air in, ERVs can improve ventilation without wasting as much conditioned energy. The result is steadier indoor air quality alongside better efficiency.

Fresh air matters—especially when winters tighten homes

During long heating seasons in Illinois, indoor spaces often become sealed to reduce drafts and energy loss. While that can help comfort, it can also reduce the exchange of air that removes moisture, odors, and pollutants. Poor ventilation can contribute to problems such as lingering cooki ... Read more »

Gas line installation, replacement, and certain maintenance activities in Illinois generally require permits, inspections, and compliance with multiple layers of code. Requirements can vary based on whether the work is in a building or on/near utility-owned infrastructure, and whether the job is performed by a licensed contractor, a utility, or in coordination with a local jurisdiction.

Because gas systems are high-risk infrastructure, Illinois’s approach combines technical code standards (adopted building/fire codes) with safety-focused regulations. Before starting, contractors and property owners should confirm the applicable permit path with the local building department and the relevant gas utility or pipeline operator.

Key codes and standards commonly referenced

For most building-related gas work, Illinois jurisdictions typically rely on adopted versions of the International Fuel Gas Code (IFGC) and ... Read more »

Radon is a radioactive gas that forms in the ground and can seep into homes through cracks in floors, walls, and foundations. Because it is invisible and has no smell, the only practical way to know whether your home has elevated levels is to test.

Illinois’ weather and housing stock—ranging from basements to slab-on-grade homes—mean radon pathways can vary widely even between nearby properties. That’s why experts recommend testing at the address, not relying on neighborhood averages.

When should you test in an Illinois home?

If you haven’t tested before, schedule a test as soon as possible. You should also retest if you move, finish a basement, seal major openings, install a new HVAC system, or make other structural changes that could alter airflow and pressure.

For many homes, radon testing is most informative during typical living conditions. Use the instr ... Read more »
