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.

Diagnosis and Options –  When our technician completes the evaluation, they will provide you with an itemized list of everything required.  We believe in full transparency and not over-selling.  We want lifetime customers’ and would never jeopardize that.  Our technicians will also apprise you of any warranties or service plans that may be of use to you.  The will provide you with a timetable for the repairs as well as take as much time as necessary to answer any questions you may have.  Once this is done, they will ask for your signature authorizing the repairs.

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. The work review process will be explained per the service ticket so that you can follow along to make certain that everything explained matches.

The Close –  It is at this point where we are almost done.  Once payment has been made, our technicians are instructed to contact our dispatch for a quick exit interview with you.  The technician will place you on the phone to insure that you are completely satisfied prior to our technician moving on to their next call.

We go through this process for one simple reason,  we want our new and existing clients to know that it only take 1 Call for all your AC, Heating, Plumbing and Drain issues.  We hope you become one of our satisfied customers.
