Meet The Owner

Edgar Connery, owner and president of ONE CALL, is a Houston transplant originally from Detroit, Michigan. He grew up working in the HVAC and Plumbing field, first as a rookie tech climbing the ladder. Edgar noticed how some companies and technicians were unfortunately paid on commission, ultimately using sales tactics to sell a customer what they did not need or even want, and sometimes downright lying to customers. This isn’t the way business should be conducted, so he began ONE CALL to change the industry.

Since opening doors 21 years ago right in the heart of Montrose, his service techs have never been paid on commission. This makes for an honest, personal, and neighborly service for all residents of Houston.

His philosophy has grown so popular, in fact, that most customers, new and returning alike, ask for him by name.

The Introduction – When our technician arrives at your door, he will properly introduce himself, review the nature of the service dispatch and request permission to enter the property to assess the situation.  Prior to entering, our technicians will put on protective foot coverings to prevent any tracking of dirt and to just show that we care about your home or office.  We do this to make sure nothing has changed, that message sent was message received and to clarify the rest of the initial call.  This includes reconfirming how payment will made should you authorize us to perform the work.

As the technician is looking at the issue, he will be asking you questions to further understand the issue as well as understand your expectations.

The Repair / Installation –  Once authorized, our service technician will perform the work exactly as explained.  When completed, they will review all of the work done as well as perform any testing necessary.
