15 Amp Outlets

I took apart an existing wall in my home and found that 15 amp outlets were used on a 20 amp circuit. Should these be replaced with 20 amp?

No, this is specifically permitted in the (US) Code. Any 20 Amp circuit with more than one recept may have a mix of 15 and 20 Amp recepts. Art. 210-21 and 210-24

plan to put an actual 20 amp load on an outlet, then change that one.

As long as the 20 amp circuit does not feed through the receptacle it is perfectly acceptable. The 15 amp receptacle should be pigtailed to the #12 wires if they feed in and feed out.

Nope, 15a NEMA devices are rated for 20a feed through.

No. A 20 amp single load needs a 20amp plug, which won't fit in a 15 amp outlet (one of the lugs is twisted). These are uncommon in the US, usually only big heaters will have a 20 amp plug.
Unless you have a load that won't fit the outlet, you won't gain anything by switching.

You can use 15A outlets on a 20A circuit, the code only requires that one of the outlets be on a 20A curcuit to be a 20A outlet. However, I personally would consider that to me a poor practice and put only 20A outlets on 20A circuits.

Code only requires a 20 amp outlet if it's the only one on the circuit. The NEC does not require that one of a group be so.

A 20A circuit with nothing but a single duplex 15A outlet is just fine. I'm not sure if that one device was a simplex 15A outlet.
We are talking about exceptional cases, and regulations sometimes get rather messy at the boundary conditions. I wouldn't worry about it.

Although you can use 15 amp outlets on a 20 amp circuit, I use 20 amp "commercial grade" outlets. These are designed for more use, will last longer, and will make better electrical contact with the plug.

15A commercial outlets are just as good, and about $1 cheaper. I put one 20A outlet in the kitchen and one in the garage (just because; I don't think I have anything with a 20A plug), and I use those cheap 15A 47 outlets in bedrooms and other places where they may never get used, and I use the more expensive commercial or "spec grade" 15A outlets everywhere else.

Here is my understanding of the 15A/20A receptacle situation. The difference between 15A and 20A receps is the pin slot on the hot side. The 20A recept will take a 20A plug which will NOT fit into a 15A recept. Either receptacle will take a 15A plug. The 15A receptacles are RATED at 20A, that is they can be and are used on 20A circuits. The 20A receptacle (probably) should not be used on a 15A circuit since a device with a 20A plug implies that it needs current in the range of 15 to 20A. You can find this info written on the boxes or even on the recepts themselves -- if you are willing to read the into. --Phil
