Troubleshooting An AC That Is Not Cooling

Most people rely on their HVAC systems to keep their homes cool and comfortable during weather changes. In some cases, HVACs are not appropriately maintained producing poor efficiency. Such a scenario typically starts with diminished cooling performance which develops into a more evident issue where the AC stops cooling completely and spits out hot gusts of air. You will want to sort this issue out as soon as possible when your air conditioner stops functioning correctly.

Leading causes of your air conditioner generating hot air.

There are various causes why your air conditioner releases hot air instead of cool, pleasant air. Listed below are the most common causes:

  • Unclean Air Filter

The most frequent cause of air conditioning repair in Lake Dallas, TX, is dirty air filters. A dirty filter will also result in inadequate cold airflow because of the buildup in your air conditioning system.

Solution: If the AC filter is clogged, it is advised to have it checked and replaced frequently to prevent air conditioning repair in Lake Dallas, TX.

  • Faulty Thermostat Settings

If your air conditioner first sends out cool air, then lukewarm air, there is a problem. If you find yourself in this circumstance, put the thermostat to automatic. In this manner, the fan only operates during the cooling of the air.

Solution: The thermostat should always be set to auto mode rather than on. It is a typical cause of your air conditioner not cooling.

  • Unclean Exterior Unit

The evaporator transfers heat from the air around you to the air conditioner outside. The air conditioning system cannot be adequately cool if the condenser is clogged. Even heat transfer will be impeded by debris and dirt.

Solution: Clearing the weeds and dirt around the condenser may clean it and give it plenty of breathing space. Get your air conditioning equipment fixed and maintained regularly by a professional to prevent maintenance costs.

  • Low Level Of Refrigerant

Without a refrigerant, which is a vital fluid that absorbs heat from the air around it, your air conditioner might not cool. If your air conditioner isn’t cooling, there may be a leak in the refrigerant system. To prevent this issue, have routine AC service in Lake Dallas performed.

Solution: A buildup of ice on the outer unit and hissing or bubbling noises are signs that can help you locate the problem. Once the issue has been located, contact an expert to resolve it.

  • Damaged Compressor

A compressor is an essential part of an air conditioner because it controls refrigerant flow between the condenser and evaporator. A damaged condenser cannot sufficiently cool the air.

Solution: Replacement is necessary for a compressor that is damaged. Hire a qualified expert to fix this for you.
