When Donley A/C & Plumbing opened its doors in 1976, the Phoenix Valley was home to just over one million residents. Nearly five decades later, with more than five million people now calling the region home, Donley is celebrating 50 years of helping homeowners and businesses stay comfortable with reliable air conditioning and plumbing services across the Phoenix metropolitan area.
The company has grown into a trusted home service provider for families and businesses throughout Maricopa County. Donley has built its reputation over the decades on a simple philosophy that has earned it an A+ rating from the Better Business Bureau. Do what’s right for the customer, explain their options clearly, and take care of the people who serve them.
“Phoenix has grown tremendously over the past 50 years, and we’ve grown right along with it,” said General Manager Mike Donley. “We take the time to walk customers through what’s going on in their home, what their options are, and what makes the most sense for them. If you take care of your employees, they’ll take care of your customers. That mindset has guided us for five decades.”
Donley’s longevity has been driven by the people behind the brand. The company has built a workplace where employees stay for decades and take pride in helping customers across the Valley. Several team members have been with Donley for more than 35 years, and two employees recently retired after more than 40 years of service.
For many customers, that consistency means hearing familiar voices on the phone and seeing trusted technicians arrive at their homes year after year.
As customer needs and technology evolved from early systems to today’s high-efficiency equipment, Donley expanded its services to better support the homeowners they serve. A key turning point came in 1990, when the company made the strategic decision to build out its plumbing services division. That move transformed Donley from a seasonal HVAC business into a stable operation, better positioned to serve customers and create long-term opportunities for employees.
Over the past five decades, Donley has supported more than 40 charitable organizations across the Valley, often doing so quietly.
Among those organizations is Child Crisis Arizona, formerly known as Crisis Nursery. When Donley first began supporting the organization, it operated out of one or two small buildings, providing emergency shelter for vulnerable newborns and their families. Today, Child Crisis Arizona has grown into a major community resource, a transformation that reflects the same long-term investment Donley believes in.
“Our community has supported us for 50 years,” Donley added. “It’s only right that we support it in return.”
As Donley celebrates its 50-year milestone, the company remains focused on the same principles that built its reputation – serving customers with expertise, investing in its people, and showing up for the communities it calls home.
“At the end of the day, it’s about doing right by the customer,” said Operations Manager Ken DiCicco. “You see that reflected in the people who’ve been with us for decades – employees and customers alike. That’s what built this company, and that’s what will carry it forward.”
