The Twin Cities is well known for the coldest winters in the country, yet in the summer, the heat and humidity go way up. Much of this is attributed to the urban heat island effect, a phenomenon brought about by too much concrete and asphalt in the city, and tall buildings that keep the wind out. On days when temperatures are soaring, everyone takes refuge by staying in the air-conditioned comfort of their homes.
Nothing can be more frustrating, therefore, than turning on your air conditioner to find that hot air is blowing, a strange and unpleasant noise has taken over your AC, or absolutely nothing happens at all. When this happens, here is a short troubleshooting guide to run through before calling for Plymouth, MN AC repair experts like those at Marsh Heating & Air Conditioning Co., Inc.
What to Check
Look at the area all around your air conditioner. Remove all leaves, debris, grass and flowers surrounding the system. Clearing this area allows for unrestricted air flow and prevents unintentional obstruction.
Sometimes a thermometer can be malfunctioning. You may feel air blowing, but do not see a temperature change. In addition, the thermometer might be on an energy-saving setting that is keeping the air conditioner from turning on. Check your settings and any other energy saving controls to see if these are preventing your AC from working.
If this is not causing the problem, check to make sure that everything is plugged in. While this seems a bit obvious, it is not uncommon in the winter to unplug what is not in use and plug in seasonal appliances such as a humidifier or holiday lights. If this is not the root of the problem, check the filters. Hypo allergenic filters do not last as long as traditional filters.
When to Call the Professionals
When you turn up your air conditioner and there is a weak stream of air, or warm air is blowing from the vents, then it’s time to contact a reliable heating & air conditioning company. If the fan is not moving, yet the furnace is on, call for service.
If the AC repeatedly turns on and off, have it checked by a professional immediately. There may be a serious blockage, a damaged fan, or other technical problems.
If your AC is making unusual sounds, like a hiss, gurgle, or squeal, this usually indicates a more serious problem. It could be a leak, a faulty belt, a compressor problem, low refrigerant or other serious concerns that require that require the services of an expert.
