Nothing against small outfits but try to stay away from low overhead Lou or Joe's heat em and cheatem. You get what you pay for and even though the bigger outfits charge more $$ they can attract better techs as they pay us more than Lou or Joe.
They should have a checklist of what they do and be willing to show it when done or if you ask nicely first. If you have your own and hover over their shoulder they will get snarky and not do a great job. Nobody likes a customer hovering and that goes for regular folks in their jobs as well.
They should wash the outdooor coil and check the freon pressures and compare them to the manufacturers specs for the outdoor temp at the time. They also check the superheat/subcool and temp difference across the cooling coil of the air. These are the most important items. There are others on the checklist which are too numerous to mention and like I said you don't want to hover with that list and a pen checking them off.
Checking the drain from the indoor coil and flushing it is very important.
You could ask the company if they are sending a licensed Journeyman and say you want that rather than a appprentice. The companies with the $99 to $109 checkup special will use lower paid apprentices. The companies who charge more and don't have a "special" may use Journeymen who know more. Nothing wrong with some apprentices but the first level ones are just coil washers and cannot recognize serious problems.
