Agree- Id be inclined to check their work.
First monitor for a few more days- check under your radiator cap 1st thing in the morning when engine is cold to be sure radiator is full to top of the neck. Also make note of and keep an eye on coolant overflow bottle levels (hot and cold) to make sure the cap is working correctly.
Last resort if still running hotter than you think it should- and this will prob void what ever labor warranty you have with shop that did the install- but Id want to double check their work and ensure the thermostat was correctly positioned.
Partially drain off the radiator into a clean (large) bucket, enough to drain the upper and lower hose off, (you also might pull the accessory belt off before you do this as not to get coolant on it) then pull the thermostat housing and make sure the thermostat is installed in the right direction, and the jiggle valve is 12oclock position. If its in correctly, bob’s your uncle. If its not, snap a photo and take it to the service shop. Button back up.
Burping process can be a little time consuming, front and rear heaters on full hot, front end raised up (12” or more)- or use one of these no spill funnel kits- these work great for burping.
