What type of Air Conditioner does your Home REQUIRE to Cool your Home:
If your Air Conditioner is Sized correctly, even the most basic 13 SEER Central Air Conditioning unit will cool down your home. The efficiency of an air conditioner is measured by its SEER rating. SEER (Seasonal Energy Efficiency Ratio). The SEER rating of any air conditioning unit basically reflects the cooling output of an AC over the amount of hydro energy it uses.
Most salespeople in the Hvac Industry will recommend an ultra high efficiency (read :expensive) central air conditioner to their customers to make higher commissions.Despite what any salesperson tells you, a 13 SEER unit will cool just about any home comfortably.
Should you even Consider Installing a High-Efficiency Unit?
Prices for Units above 16 SEER start to get ridiculously high. You should go for an air conditioner that supports both your home and financial needs. Generally, a 16 SEER unit is 20% more efficient than a 13 SEER (read:basic) air conditioner. If you get a fairly heavy hydro bill in the summer (either because of excess usage or owning a large house) you should consider a 16 SEER unit because:
You should spend a couple of minutes to calculate your payback period for the extra cash you spend on a high efficiency air conditioner. Simply Math.
.20 [20% energy saving with upgrade to 16 SEER] x Average Summer Monthly Bill = SAVINGS
Then, SAVINGS x 4 = Monthly Savings (4 Months average usage of Air Conditioner in Canada)
