a. All depends what city your in on utilities ..How many sq ft is the building..I am in the south so heat is almost nothing even in the winter at the peek summer months my electric is high..1 theater 12,000 sq ft my electric is $3,200 summer $1,600 winter. Theater 2- 20,000sq ft $5,500 month summer not sure as i have not been in the winter. Garbage on both about $80.00 per month.
b.Deep cleaning and repaires-- again --How old is the building and your equipment.That is the key to that question. AC HEAT is what can get you.. New unit almost always $12,000. We pay $1,300 for service 4 times a year on heat and ac. The rest depends how many screens.
c. Both my theaters are in centers so i do not have those figures.
