ON Services Mechanical, Electrical, Plumbing, & HVAC

ON Services Mechanical, Electrical, Plumbing, & HVAC operates from Mesa, Arizona, delivering integrated trade services across plumbing, electrical, mechanical, and HVAC systems. The company maintains a 4.6-star rating derived from 244 customer reviews, positioning it among the more frequently reviewed contractors in the East Valley region. Operating under the On Service brand name, the business provides around-the-clock availability seven days a week, including holidays.

With service hours spanning every day of the week, ON Services offers multi-trade capabilities allowing homeowners to coordinate plumbing, electrical, and climate-control work through a single contractor. This integrated approach can streamline repairs that involve overlapping systems, such as water heater replacements that require both plumbing connections and electrical work. The company serves residential customers throughout the Phoenix metropolitan area.

Two recent customer reviews describe specific service experiences. Pauline Smith noted that resolving a bathroom leak required three separate service visits, with the final technician successfully addressing an issue that had persisted after earlier attempts. K Stack documented a three-year-old sewer repair that later failed, describing concerns about communication and workmanship transparency during the original scope of work.
