One appliance that homeowners are usually thankful for during the warmer months of the year is their air conditioner. If your air conditioner is not working as it should, you might not feel as comfortable at home. Feeling warm for prolonged periods can affect your health and overall wellbeing. For this reason, if you notice any of these three problems, you should get air conditioning repairs right away.

1. Warm Air

If your air conditioner is blowing out warm air, instead of cool air, this is a problem. Warm air might mean there is debris blocking your condenser unit. A dirty air filter, leaking refrigerant, or leaks in the air ducts are other possible reasons your air conditioner is blowing out warm air.

Another issue is that your air conditioner might not blow out enough air. When this happens, it could mean the evaporator coil has frozen. Other reasons for air conditioners not blowing out enough air include a disconnected air duct or the blower motor is not working correctly. Whether your air conditioner is blowing out warm air or not enough air, it's probably time for air conditioning repair.

2. High Humidity Levels

Besides cooling your home, your air conditioner should also be reducing the humidity levels in your home. If you feel wet or sticky inside your home, it probably means your air conditioner is not working as it should to decrease the humidity. The reason for this is your air conditioning unit might not be the right size for your home.

Other reasons for high humidity levels inside your home include:

• Leaks in the duct system
• Dirty evaporator coil 
• The thermostat is set to "auto"

High humidity levels inside the home promote the growth of mold and mildew and can even damage the furniture, flooring, and paint. Because of this, you should seek air conditioning repair if there is too much humidity inside your home.

3. High Electric Bill

When it comes to paying bills, most homeowners don't like paying more than they have to. This includes the electric bill. If you have noticed that your electric bill has increased since the previous summer, your air conditioner may not be working as efficiently as it should.

Air conditioning problems that decrease efficiency include a dirty filter, leaky air ducts, or low refrigerant levels. An inefficient air conditioner might also indicate that certain parts are not working as they should or the unit was not properly installed. If your electric bill is too high, contact an HVAC technician for an inspection and air conditioning repair.
