Best Air conditioning repair service in Chicago for SameDay Service

Oasis Plumbing, Heating & Cooling is a combined plumbing and HVAC company based on Western Avenue in Chicago's West Ridge neighborhood, with a second location in Elmhurst serving the northern suburbs. Its services span plumbing and water heater work, furnace and heater repair and replacement, air conditioning repair and replacement, and maintenance plans. Reviewers note the company uses Manual J load calculations when sizing replacement systems, a more precise method than matching the old unit's size. Technicians named Chris, Serge, Harvey, and Fernando appear in reviews: Chris is credited with a well-executed hot water tank installation and deep plumbing knowledge, while Serge and Harvey handled a furnace and AC replacement with clear estimates and strong communication. Several reviewers highlight no-upsell pressure — repairs fixed at reasonable prices rather than fabricated replacements. One reviewer reports a poorly handled appointment for a condo hot water pressure issue. This is a fit for north-side Chicago and northern suburban homeowners who want one company for both plumbing and HVAC. The maintenance plans suit anyone wanting seasonal tune-ups with repair discounts and priority scheduling. For full system replacements, the load-calculation approach appeals to homeowners who want equipment sized to the home rather than the guess.
