What is the rule of thumb for HVAC cooling?

The 1.7X rule

This rule of thumb states that the MAX heating capacity required for your comfort cooling application is 1.7 x the cooling load. For example, if the cooling required is 30 tons (360,000 btus), then the MAX heating capacity required would be 612,000 btus (1.7 x 360,000).

What happens if your AC unit is too big for your house?

Air conditioners that are too big consume more energy, endure more wear and tear, and simply don't work as well or as long as an appropriately sized unit. This can cause higher utility bills, more repairs, and discomfort in your home.

What happens if AC is too small?

As previously mentioned, air conditioners absorb heat and humidity from your home. If your unit is too small for the square footage, it won't absorb all of it. This means you'll be sitting in a room that feels just as hot as outside, completely undoing all of the good work of paying to run an AC unit.

Is a bigger AC unit better?

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.

Can I go from 3-ton to 3.5 ton AC unit?

There is some leeway, like a 3-ton condenser to a 3.5 air handler. The short answer is, you can't. A good tech might be able to get it to work with like a TXV, but you are going to be bottle-necked at the 3-ton. There is no way you will get 5-ton capacity after that.

What size AC do I need for 3000 sq ft?

How long do 4 ton AC units last?

How long do AC units last?
