Effective Planning

We offer site visits for our customers. Mainly Custom will carefully review your heating needs, placement of furnace and discuss the regulations that are in place. We will provide you with all the information you require for your overall investment. Technical advice and support is only a phone call away. Because Mainly Custom is a full service company, we will personally fire up your installed boiler the first time you operate it! Try having THAT service offered to you from a “sales person”!
