Heat pump air conditioners keep New Haven, CT homes cool and comfortable in the heat of summer. Unfortunately, when your heat pump air conditioner fails, your home can become stuffy and uncomfortable in no time. The easy-to-follow troubleshooting tips will help you to identify common problems and to remedy the situation quickly. Remember to contact your local HVAC contractor in New Haven, CT for assistance if any specialized repair tasks need to be performed.
The first step is also the easiest one. Thermostats can be moved to an incorrect setting by accident, resulting in your heat pump air conditioner not cooling your New Haven home effectively. Ensure that the thermostat is set on cool, and that it is set to a temperature that is lower than the actual temperature inside the room. Did you know that dirty air filters block airflow and thereby impact negatively on the efficiency of an air conditioner? It is therefore suggested that you change the air filters once every three months, and more often when in peak use. Check the air filters and replace if required to fix this problem.
The heat pump air conditioner can't operate effectively without an adequate level of refrigerant. Refrigerant leaks drain refrigerant from the system, and the air conditioner will be unable to provide cool air when the refrigerant level falls below the critical level. Frost on the lines connecting the indoor and outdoor units in New Haven, CT, or water pooling around the furnace, are indicators of a low refrigerant level. Check for this problem by switching the outside unit off while keeping the furnace blower on. Thereafter, restart the air conditioner after a couple of hours and check to see if the large copper line at the outdoor unit is cold and has condensation on it. If frost forms on the line, or if it is not cold within about 10 minutes after restarting the system, the refrigerant level is too low.
Another test that you can perform is to measure the temperature of the air leaving the air handler, and the temperature of the air entering the air handler. The temperature drop is the value that you get when you deduct the temperature of the air leaving the air handler from the air entering the air handler. The ideal drop in temperature should be between 15 degrees for high efficiency units, and 20 degrees for older units. Significantly lower results indicate problems with the refrigerant charge, and significantly higher results point to problems with the air flow.
Dirty filters or coils restrict the air flow of your heat pump air conditioner, and should be checked, cleaned or replaced on a regular basis. If you identify that the refrigerant level is too low, fix the problem by asking a suitably qualified technician to check for leaks, and to top-up the refrigerant. Note that only suitably qualified HVAC technicians in New Haven, CT are allowed to top-up or drain refrigerant from an air conditioning system.
Heat pump air conditioners can malfunction or operate at inefficient levels from time to time. Fortunately there are easy-to-follow troubleshoot tips that can help you to identify and repair the problem quickly. One of the key factors of a satisfying relationship with your heat pump air conditioner is regular maintenance. Regular or preventive maintenance will ensure that your air conditioner perform at optimal levels, and will also reduce repair costs in the long run.
