I am a skilled professional that works for a Central Comfort company. I recently completed a job for a customer who wanted to convert their high-efficiency Viessmann boiler and indirect water heater from oil to natural gas. The job involved removing the old oil burner and installing a new natural gas burner, as well as replacing the indirect water heater with a new model. The customer was very pleased with the results of the job, and I was able to provide them with a free estimate for the work. I also provided them with information on the benefits of converting to natural gas, such as lower heating costs and a more environmentally friendly option.
