If you keep questioning if the air conditioning is even working because the house isn't getting very cold, but you can hear it turn on and off, the problem may be a lack of refrigerant. Over time the refrigerant tank can have complications like:
- Rusting or corrosion
- Vibration damage
- Weakened joints or connections
- Tube wall tapering
- Manufacturer defects
When this happens the ac unit doesn't work as needed. You don't just want to have the refrigerant level checked, but it is a good time to have the air conditioning unit maintained and tuned up as well. Call an air conditioning repair professional if you have these concerns.
The Air Isn't Cool Enough
If the air isn't getting as cold as it needs to, this could be because there isn't enough refrigerant. Refrigerant is the chemical that cools the air to push it through the house, and if levels are low it's likely there is a leak.
Energy Bills are Rising
Low refrigerant levels will cause the air conditioner to have to work harder and longer to get the air cool. This means that the unit won't be as efficient as it should be, and your energy bills will be on the rise. Increased energy usage can indicate a variety of air conditioning problems and a potential refrigerant leak.
The Fan is Frozen
The fan may be frozen if most of the refrigerant has leaked. This will stop the fan from moving and can cause the air conditioner to overheat and have other issues. If you can't hear the fan moving, or air isn't blowing through the house, this could be the problem.
First and most importantly you'll need a diagnosis and quote to get the unit repaired. During the tune-up, the ac repair professional may find other problems that need to be addressed, or components inside the unit that should be replaced.
You will also want to have your thermostat looked at. There can be issues or errors with the thermostat and mixed signals could be getting sent to the HVAC units. This may need troubleshooting or a reset after the ac unit is fixed, to be sure that the thermostat communicates with the ac unit after it's repaired.
The tune-up will also help to improve the efficiency of your air conditioning unit. If your air in the house isn't cool while the thermostat is set to air condition the home, call and figure out what the problem is fast.
