All Temp Heating and Air Conditioning

All Temp Heating and Air Conditioning has kept Chicago-area homes comfortable since 1938, building nearly nine decades of documented service excellence. Based in Chicago with additional offices in Bolingbrook, Hillside, and Northbrook, the contractor holds a 4.9-star rating across 2,357 client reviews, a volume of feedback that speaks to consistent execution across tens of thousands of service calls. Their territory includes the city of Chicago proper plus these three suburban hubs, serving both single-family residences and larger residential properties. The company operates around the clock, every day of the year, fielding emergency calls for furnace failures, AC breakdowns, and heating system emergencies.

What distinguishes All Temp from regional competitors is their investment in diagnostic thoroughness and manufacturer partnerships. The company offers installation and service for specialized systems including Spacepak AC, Unico hidden-duct installations, and ductless heating and cooling solutions that work well in older Chicago homes where traditional ductwork would compromise architectural details. Their residential portfolio extends beyond temperature control to indoor air quality, UV lights, air purifiers, heat recovery ventilators, and whole-home dehumidifiers address the humidity extremes that define Chicago summers and the dry indoor air of winter. Financing options and a Comfort Club maintenance program give homeowners predictable costs rather than reactive repairs.

Customer reviews name specific technicians who elevated routine service into trusted relationships. Ed guided newcomers through their boiler and radiator system, explaining how radiators function and performing maintenance that prevented future failures. Marvin discovered internal furnace cracks that an external repair would have missed, a safety issue caught only through his insistence on internal camera inspection. Randy arrived same-day despite a unit mounted awkwardly near a child's window, correctly diagnosing the issue on the first visit. These scenarios illustrate why reviewers specifically request these technicians for future service.
