ENERGY STAR estimates leaky ductwork can cut heating and cooling efficiency by up to 20 percent — and duct sealing is not the same service as duct cleaning. Here's how to spot leaking ducts and what fixing them actually involves.

The federal HVAC tax credit ended after 2025. Here's what's actually still available in 2026 — Nicor Gas and ComEd rebate programs — and how to make sure the paperwork gets filed correctly instead of left on the table.

Cold-climate mini-splits keep producing heat well below 0°F, but that doesn't make them the right fit for every room. Here's where a ductless system solves a real problem in a Chicago home — and where a conventional furnace or AC replacement is still the better call.

Multiply the repair estimate by the furnace's age in years. Above roughly $5,000, replacement usually wins. Here is how the rule works, where it breaks down, and what a real replacement quote should contain.

Modern cold-climate heat pumps produce useful heat well below zero Fahrenheit. Most Chicagoland installations pair one with a gas furnace so the furnace covers the coldest days — and ComEd rebates run through 2026.

Most Chicago-area homes need far less furnace than they have. Sizing by square footage or by matching the old unit produces oversized equipment that short cycles, wears out sooner, and heats less evenly.

Chicago winters are long and heating is a big line item. Here are the changes that actually move the needle on your bill.

Geothermal energy solutions offer a smart, eco-friendly way to keep indoor temperatures comfortable year-round. These systems tap into the earth's natural heat to cut utility bills. Here is why geothermal heating and cooling is worth considering for the Chicago area.
