Today I met Angela at her daughters Okotoks condo because she wants to get air conditioning installed. Upon inspection of the 1000 sq/f home I found a single head 1 ton ac system would be the best and most economical solution. Because running electrical for a 220-240 volt system would be difficult, a 120 volt system would be preferable. I will do some research tomorrow to see if there is a system that will fit the space and use 120 volts.
