A malfunction in your air conditioning unit could be a serious concern, especially during the heart of summer. You don’t want to ignore performance problems because more serious damage could result if an issue isn’t handled promptly. However, a little bit of troubleshooting may reduce your stress as you pinpoint the type of problem. Some issues can be corrected without assistance from an HVAC company. Others may indicate the need to enlist the help of a professional.
Poor Comfort Levels
If you notice that the air blowing through your registers isn’t very cold or that the pressure isn’t very strong, you may be dealing with a system that needs an air conditioning tune-up. Dirty coils can restrict airflow and inhibit energy exchange between indoor air and refrigerant. A tune-up includes cleaning of the air handler and may produce a marked improvement in the performance of your system.
Hot Air Blowing
If your system is producing hot air, there may be a simple explanation. Verify that your thermostat settings are correct. An unexpected change by an uninformed family member could result in heating equipment operating, and you may have a quick and easy resolution. If your system isn’t operating but you feel hot air coming out of some or all vents, you may have duct leaks that need to be sealed. Your HVAC contractor can assist with these services. If the system is operating at correct settings but blowing hot air, you may have a refrigerant problem. Check the evaporator coils in your air handler to see if they are cold. You’ll need to have a technician diagnose damage in your refrigerant lines and recharge the system.
System Won’t Operate
The thermostat should be checked to confirm that settings are correct. Additionally, you may need to ensure that batteries for your thermostat are working. If these aren’t the source of your problem, you will need to verify that an interruption in the power supply hasn’t occurred. Check your fuse box, turning on a tripped switch if necessary.
If the power supply is fine, then you will want to check your filter and coils. A clogged filter can impact system operation, and you should make a monthly filter change to ensure good air conditioning performance. You may also find that ice has developed on your coils. Allow it to defrost before turning your system back on. If the ice returns, you may have poor refrigerant levels or other issues that require professional diagnostics.
There are many types of sounds that can develop as your Air conditioning equipment operates. Vibration may indicate a loose or deteriorating part. Screeching may indicate a worn belt. Grinding may be a sign of dry bearings. Humming could indicate problems with refrigerant levels. A new sound shouldn’t be ignored. Although the issue could be minor, ignoring a more serious issue could result in permanent damage to your equipment.
