About Service Plus Mechanical A family-owned HVAC company, Service Plus Mechanical runs on the simple principles of honesty, integrity and hard work. After earning his HVAC certification, owner and operator Cesar Covarrubias began his business out of his own garage. In only a few short years he had developed the company beyond its humble roots to include a team of dedicated pros and a network of service vans that run from their office location to homes throughout Fox Valley and into Chicago. Service Plus Mechanical’s team dedicates themselves to staying up-to-date on the latest HVAC training and education. They put the client first, focusing on building long-term, loyal relationships with customers. As a result, Service Plus Mechanical retains customers, obtains referrals and continues to grow and prosper. The recent addition of top-of-the-line duct cleaning equipment reflects Service Plus Mechanical’s dedication to providing new services to customers looking to have the best air quality in their homes. Service Plus Mechanical also gives back to both the HVAC industry and their community. This year, the company became a part of ComEd and Nicor’s Contractors’ Circle. They are also active in initiatives that give back to the community. Learn more by visiting the Community Involvement section.
