All Temp Heating & Air Conditioning

All Temp Heating & Air Conditioning has kept Chicagoland homes comfortable since 1938, building nearly nine decades of expertise across multiple generations of homeowners. Based in Northbrook, this licensed contractor holds a strong 4.6-star average across 23 verified reviews, demonstrating consistent service quality despite one outlier complaint. The company operates around the clock with 24/7 emergency response, serving Chicago, Bolingbrook, Hillside, and Northbrook alongside surrounding suburban communities. Their longevity in a demanding regional market speaks to reliability across brutal Midwest winters and humid summer heat waves.

What distinguishes All Temp is their investment in premium brands like Spacepak and Unico systems, which offer low-profile central air solutions that outperform conventional boxy units in older colonial and ranch-style homes common to the North Shore. They also stock ductless mini-split configurations ideal for additions, sunrooms, or homeowners seeking zoned comfort without extensive ductwork. A financing program enables major installations to fit household budgets, while their Comfort Club membership provides scheduled maintenance that protects new equipment warranties. For properties with legacy boiler infrastructure still in operation, their technicians service these aging systems rather than automatically pushing complete replacements, one concrete way they respect customer investments.

Customer experiences vary, and transparency matters here. A Northbrook homeowner named Andrew earned praise for diagnosing airflow restrictions that two prior contractors missed, arriving promptly and resolving the issue in a single visit. However, another client reported significant frustration with a near-$20,000 installation involving delayed drywall repairs, untaped duct connections leaking into attics, and cooling performance that failed during the region is first summer heat wave. These contrasting outcomes, both visible in public reviews, illustrate that execution quality can differ between crews or jobs.
