Poston Brothers, Inc. is celebrating the 75th Anniversary of the business this year. Elza Poston and his brother Paul Poston opened the business in 1929. In those days most of the business consisted of coal-fired heating equipment. Times have changed and Poston Brothers has changed along with them. Coal heating systems have been replaced by Ultra-High Efficiency geo-thermal heat pumps and variable speed, multi-stage gas furnaces. Poston Brothers is pleased to offer service to residential, commercial, and industrial customers. Poston Brothers is one of the leading heating and air conditioning sales and service companies in the Tri State area.
