The following industry standards apply to locations where accumulating / not draining properly condensate would damage building components, which includes the attic installed air conditioning coil.
Making seasonal inspections of your furnace and air conditioning system makes sense, and I’d highly recommend having it done on a regular basis on any age furnace and AC units. The question is – do you trust your HVAC guy? Most people do, because they are always very happy to announce at the beginning of [...]
We notoriously forget to replace air filters in our forced air heating / air conditioning systems… Air flow starts deteriorating through the house, system seams to be operating, but it takes significantly longer to achieve desired temperature … The solution might be simple – clogged air filter, or missing air filter, and in that second [...]

Refrigerant lines insulation is partially responsible for the efficiency of your air conditioning system operation. Two different diameter copper pipes (one approximately 1/4″, second 3/4″ – diameter depends on your system size), run between the air conditioning system condensing unit (house exterior), and the AC coil (“A” coil – named after its shape) installed inside [...]

House AC condensers require their own disconnect switch. AC disconnect must be located in sight and not directly behind the condenser so it’s easily accessible. Depending on the manufacturer, enclosures have a disconnect handle located on the exterior or behind the small cover. Accessing of some older air conditioning disconnect switches with a hidden handle might be difficult, they are often corroded, [...]
