Today I came to Darren’s Cochrane home because he would like to have a central air conditioning system installed. Upon. Inspection of the home I found it will require a 3 ton cooling system. The furnace is high efficient and just repaired by Clearview last year and is working well. There is room on the existing electrical panel to accommodate the ac system. There is no indoor air quality system. Darren will discuss the standard and basic options with his wife tonight and will have a decision by tomorrow end of day at the latest.
