Had a great day helping out one of our valued customers who called us with the specific problem of their old and faltering hot water coil. Neatly and systematically, we replaced the hot water coil with a brand new one following a set process. We cut off the water flow to the ineffective coil, detached it, then got the new one installed perfectly. After resume water running, we purged any trapped air from the system. To confirm everything was done right, we conducted a full heating system start-up and test, ensuring all is well and running smoothly again. Ensuring total satisfaction is always important to us and today was no different.

We swung by today at a customer's request for a hot water coil replacement job. They were dealing with some issues and rightly decided it was time for a new set-up. So we got down to business, carefully shutting off the water to the old coil, draining it, and proceeding to disconnect the water line. With the old gear out of the way, we installed a shiny new hot water coil and reconnected the water supply, ensuring to bleed any trapped air from the system. The final touch involved starting up and testing the heating system to give it a run and assure everything works perfectly. The customer can now comfortably enjoy their hot water.
