The evaporator coil is the cooling element in an air conditioning system. This component uses copper tubing to convey the cold vaporized refrigerant that extracts heat energy from warm return air. When all the parts of the air conditioner are in good working order, you should receive nice cool air at the vents. If warm air is blowing from the vents, you may find that the evaporator coil is frozen. Here’s what to do.

Thursday, December 11th, 2014
Having your HVAC system’s airflow balanced means heating and cooling airflow to every room into the house is consistent with the size of the room and balanced with the amount of air removed from of the room by the return airflow. This results in a condition of neutral air balance, considered optimum for effective and efficient heating. When airflow is out of balance, a range of performance and energy-efficiency shortfalls will affect your HVAC system, household comfort and indoor air quality.

One important goal of any forced-air heating or cooling system is a proper balance of airflow, both into rooms and back to the furnace or A/C air handler. Air balancing, simply speaking, is making sure that all forced-air vents in the house are putting out air equally. There are some do-it-yourself methods to test the air balance in your home. Try walking between rooms to see if the temperature changes. Place your hand near the ceiling to check for air flow from the vents. If the air isn’t balanced, you may need have a trusted technician install restrictors or dampeners, although the problem may be solved by adjusting or unblocking registers, replacing your HVAC’s air filter, or checking for and fixing ductwork problems, such as leaks or blockages.
