Is a bigger AC unit more efficient?

An “oversized” air conditioner will cool your house quicker, but it will use more electricity and will not remove humidity adequately. Contrary to popular belief – and intuition – long AC system run cycles are far more desirable and energy efficient than short-run cycles.

Is 12000 Btu enough for a garage?

For example, you can get a $400 12,000 BTU unit with a decent EER rating (energy-efficiency) quite easily. Whynter ARC-14S 14,000 BTU is the best 2-car garage portable AC. It has an EER rating of 12.1, a superior dual-hose design and it’s robust enough for garages.

Is it cheaper to run two AC units?

Is it better to undersize or oversize an AC?

Construction Advice: When sizing a cooling system for a home, keep in mind that it’s better to undersize than to oversize. A smaller system may run a bit more often, but it will cost less to operate. A larger system will cost more to operate, in addition to being inefficient, which will cost more money in the long run.

Is it bad to oversize an air conditioner?

An oversized HVAC unit can make your home’s inside temperature uncomfortable. An HVAC system with excess capacity can heat or cool your home faster, but that speed often results in a couple of other issues. In addition, having too much capacity can also result in higher energy costs over time.

How many BTU do I need for a 2 car garage?

How big of an AC unit do I need?

As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space. But other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power.
