We have a service plan with Boonstra, but have never had to use it other than routine maintenance. We recently smelled gas near our furnace, although it seemed to be working fine. We called and received a service visit the same day. The technician was attentive, thorough and professional. The firm always calls when the technician is on his/her way. Although a lot of customers required service at the time due to having no heat, they still made time for us. They have always been top notch and still are.
