Franchisee Success Stories
Owning a Coldharbour Heating & Air location suits a certain kind of person. Not the person chasing a logo. The person who has been in the field, or managed people in the field, and got tired of watching a good trade get run by bad habits. You know what a condensing unit should sound like. You return phone calls. You want to run a business where the promise is the product, and the product is a working furnace in January. The owners below all came from different places, but they share that same wiring. They wanted a name that meant something when the truck pulled up.
Meet Our Owners
Marisol R. - San Antonio, Texas
Marisol spent eleven years as a dispatcher for a residential plumbing and HVAC outfit before she started looking for her own shop. She saw the same pattern daily: technicians overbooked, customers waiting through four-hour windows, and the office hiding behind voicemail when the heat index crossed 100. What pulled her to Coldharbour Heating & Air was the written price rule. She told us she was done apologizing for prices that changed between the phone call and the truck. Now she runs her location with a hard rule she borrowed from her first week of training: every tech hands the homeowner a printed number before a single tool comes out. Her background in dispatch means she answers the phone herself most mornings. She says ownership changed the part of the job she used to dread into the part she is proudest of: telling a customer the exact price, the exact arrival window, and then being right twice in one day. Her market is hot, homes are older, and condensers fail hard in July. The 365-Day Done Right Promise is the first thing her techs mention, because it ends the argument before it starts.
Dale S. - Columbus, Ohio
Dale came up as a service tech, then a lead tech, then the guy who trained the new hires while the owner stayed in the office. He could diagnose a reversing valve issue by sound, but he had no interest in running payroll. What he did want was to stop watching repairs get rushed because the next call was already late. He joined Coldharbour Heating & Air because the Kingswell Way matched how he had always worked: show up in the window given, leave the basement cleaner than you found it, and if the repair does not hold, go back without charging. Dale talks about the guarantee like a tool on his belt. He issues it in writing on every single repair, and he says the reason his repeat call rate is so low is that his techs fix the actual problem the first time. Ownership gives him the authority to schedule honestly, a full hour per call when the job needs it. His story is simple: he did not change how he worked, he just found a company that was finally willing to put his standard on the side of the truck.
Colleen M. - Charlotte, North Carolina
Colleen managed operations for a regional chain of appliance service centers, which means she spent a decade scheduling people and parts across three counties. She was not a technician, and she never pretended to be. What she brought to Coldharbour Heating & Air was discipline: a calendar you can count on and a phone that never rings to voicemail after five. That live-answer standard was what convinced her to sign. She had seen too many emergency calls go to a recorded message while a family sat in a house with no heat. Now her location runs service every day of the year, and someone living and breathing picks up the phone at 2 a.m. if that is when the furnace gives out. Colleen says the smartest thing she did was inherit the training system from the Kingswell network: her techs are certified on nine residential brands, including Carrier, Trane, and Lennox, so she does not have to turn away a homeowner because the equipment has an unfamiliar badge. Ownership gave her a business where the scheduling standards she had always wanted to enforce were already written down.
Nathan D. - Boise, Idaho
Nathan bought out a retiring HVAC owner who had spent forty years running a two-truck shop on word of mouth. The trucks were well known. The paperwork was not. Nathan needed a structure he could bolt onto an existing customer base without losing the local identity those customers trusted. Coldharbour Heating & Air fit because the Kingswell network does not require every location to look identical. Each shop stays independent, owned by someone local, but works to the same written standards. Nathan kept the old local phone number and the familiar truck colors, then added the parts he knew were missing: written quotes before work, a written guarantee on every repair, and a clean job site rule his techs now follow without being reminded. He tells new technicians that the guarantee is not a marketing line. It is a discipline. If the repair fails inside 365 days, the truck goes back and the work gets corrected at no charge. Nathan says that promise has been the single biggest reason his location retains customers who had been burned by other companies before. His life changed in one specific way: he stopped waking up worried about what his techs promised on the doorstep, because now it is all written down before the condenser fan even stops spinning.
