About Oasis Plumbing, Heating & Cooling
Oasis Plumbing, Heating & Cooling works from Western Avenue in West Ridge on the Far North Side, and its website says the team has nearly 30 years of experience. It serves Chicago along with suburbs including Skokie, Wilmette, Elmhurst, Lombard, Addison and Bensenville, and it takes on residential, light commercial and commercial jobs.
The company covers heating and cooling repair, maintenance and installation, including furnaces, electric furnaces and air conditioners, and it offers seasonal maintenance plans. It also runs a full plumbing service. American Standard is the equipment brand it features. Financing is available, and the site advertises free estimates and 24/7 emergency service.
The reviews come from a lot of repeat customers. One person has used Oasis to replace an air conditioner and electric furnace in a condo and a gas furnace in a house, and says the service has been excellent each time. Another had a routine AC maintenance visit where the technician noticed low refrigerant and topped it up without charging extra. Owner Mike is mentioned by name, along with technicians such as Danny, Hani, Fernando, Amir and Joel, which points to a stable team that customers get to know.
The Google profile lists Oasis as open 24 hours. License numbers and warranty terms are not published on the pages we reviewed, so ask for both before a replacement.
Who it suits: Chicago condo and homeowners on the North Side who want a single company for furnaces, air conditioners and plumbing, and landlords with multiple units. Who it suits less well: anyone after a specialist in high-velocity or radiant systems, which are not highlighted on the site.
Before booking, ask what the seasonal maintenance plan covers, what warranty comes with labor on a new system, and whether your condo association needs a certificate of insurance before work starts.
