Drip Pan Under the Attic Installed Air Conditioning Coil
House attic heating / cooling system installations should include a protective drip pan underneath (plastic or metal tray positioned underneath the evaporator coil cabinet / compartment), to collect condensate water.
Evaporator coil will not be visible to you, because it’s hidden inside the metal duct or its own compartment, but it has a drip pan underneath. This is the main drip pan that catches...
Air Filters in Forced Air Heating / AC Systems
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 case, you might have a contaminated evaporator...

Refrigerant Lines Insulation
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...
AC Wall Units
// < 
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...
