Can I get a cheaper air conditioning system for my office at this time of year?
You may find discounts in the off season. You may also want to consider a combined heating and cooling system that will make your office or shop comfortable all year around. First off you will need to decide what type of system is best for your premises. Window units are cheap and easy to install, but only effective for a single room. A split system, with indoor and outdoor components, is capable of cooling several rooms through a duct system.
