We conducted an in-depth service on a Trane XV20i TruComfort air conditioning system, model 4TTV0024A1000B, by first cleaning its condenser coils to enhance operational efficiency and verifying that the refrigerant was at an optimal level. A new DuPont High Allergen Care air filter, model DAHC-4, was placed to elevate the interior air purity. Moreover, we adjusted the thermostat for ideal climate control and rigorously examined all electrical connections, ensuring the system operated at its best capacity.
