LICENSES: GAS SERVICE

Having grown up in the family business, Jack officially entered the trades and joined the GSMS team seven years ago because it simply felt like the perfect fit. Guided by the Golden Rule, Jack appreciates the genuine kindness of both his colleagues and his clients, and he wants every customer to know that the team will always try to do their absolute best on every job. A natural learner who loves to master new skills, Jack stays incredibly active outside of work. You can usually find him renovating his first house, woodworking, playing the guitar and drums, or experimenting with new recipes on the grill and smoker. Depending on the season, he also loves skiing or cycling. Above all, he cherishes the time he spends with his fiancé, Hope, and their Australian Shepherd, Norman. Jack is also a proud member of the Pointer Fish & Game Club.

Qwentin located a highly visible refrigerant leak directly on your indoor evaporator coil. Fortunately, we were able to locate an exact-match replacement coil for your system, which means we can get this swapped out smoothly. Here is what our team will do to resolve this: Safely recover any remaining refrigerant from your system. Remove the leaking coil and install a brand-new, exact-match ADP evaporator coil. Professionally braze the new copper connections and perform a deep-vacuum of the system to ensure no moisture or contaminants are inside. Recharge your system with the proper amount of new refrigerant and test everything to ensure it is cooling perfectly. A Note on Warranty: We checked the manufacturer's warranty status for your current Advanced Distributor Products (ADP) coil. Unfortunately, because the system is past the 5-year mark, the original manufacturer's warranty has expired.

I believe that the three way valve in the boiler was sticking and caused the domestic hot water to trigger a boiler high limit lockout. I reccomend replacing the boiler due to its age.

When a GSMS contractor comes to your home, it’s not just another contractor doing a job, it’s a personable experience from someone who truly cares about the neatness and quality of their work to the quality of their relationship with you, the customer… they quickly feel like an extension of your family making you look forward to their visits and not feeling concerned in any way how it’s going to go. Always 5 stars from me and two thumbs up, if I can count my big toes, it’s 4 digits up from me!! 👍👍👍👍🙂🙂
