    Air Conditioning

    Why is my A/C system freezing up ?

  • There are several things that can cause your HVAC system to freeze up. Most need to be corrected by a trained service technician.

    Dirty Filter: Making sure the filter is clean or replaced and making sure the airflow is not restricted are about the only things you should check or handle yourself. Should you find that your system was freezing due to a dirty filter, you can speed up the thawing process by replacing the filter and turning the system off and turning on the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, give us a call to correct the problem.

    Low refrigerant: In some cases, freezing up is caused by a leak in the refrigerant lines. The age of the system and the nature and location of the leak are the determining factors on whether to have the system repaired or replaced.

    Dirty evaporator coil: Over time, the evaporator coil will become dirty. You will need to have professional help in cleaning the evaporator.

    Defective blower motor: A blower motor not running at the proper speed or not running at all will cause freezing.

  • AFUE
    Annual Fuel Utilization Efficiency. Indicated as a percentage, AFUE tells you how much energy is being converted to heat. For example, an AFUE of 90 means that 90% of the fuel is being used to warm your home while the other 10% escapes as exhaust.

    Air Handler
    The fan blower, filter and housing parts of a system.

    Atmospheric Pressure
    The weight of a 1 square inch column of the earthís atmosphere.† At sea level this pressure is 14.696 lb/sq inch

    BTU
    British Thermal Unit. One BTU is equal to the heat given off by a wooden kitchen match. For heating systems, BTU is a measure of the heat given off when fuel is combusted.

    BTUH
    BTUs per hour.

    Capacity
    The ability of your air conditioning or heating system to heat or cool a space. For heating, this is usually expressed in BTUs for cooling and in tons for heating.

    CFM
    Cubic Feet per Minute. A measurement that indicates how many cubic feet of air pass by a given point in one minute.

    Compressor
    The compressor controls the pressure applied to the refrigerant. It is necessary for taking in heat to warm your home or getting rid of heat to keep your home cool. It is part of a split-system heat pump or air conditionerís outdoor unit

    Condensation
    The process by which a gas is changed into a liquid at constant temperature by heat removal.

    Condenser Coil
    By converting refrigerant that is in a gas form back to a liquid, the coil sends heat carried by the refrigerant to the outside. The coil is part of the outdoor portion of a split-system air conditioner or heat pump.

    Damper
    A valve used in ductwork that tightens or loosens so as to control airflow. Typically a damper is used to control the amount of air entering certain areas of your home.

    Direct Vent
    A heating system that pulls outside air for combustion and vents combustion gases directly outside.

    Downflow
    This type of furnace takes cool air from the top and blows warm air to the bottom. This type of furnace is common when the furnace is located in a second-floor closet or utility area.

    ECM
    Electronically Commutated Motor. An ECM is an ultra high efficiency programmable brushless DC motor that utilizes a permanent magnet rotor and a built-in inverter. They are significantly more energy efficient than traditional AC motors and are also much easier to control.

    Electronic Air Cleaner
    This device filters out large particles and contaminants from indoor air then electronically pulls out tiny particles that have been magnetized, such as bacteria and viruses, then draws them to a collector plate.

    Energy Load Analysis
