No Cooling from My Lexington Geothermal System



No cooling on a hot Lexington day is pretty much a nightmare scenario! While geothermal heating and cooling systems are quite reliable, they’re not completely immune to issues – below are a few common problems which could be preventing your geothermal system from providing the cooling you need.

How Geothermal Cooling Works

Geothermal systems cool homes and businesses through heat transfer. The geothermal heat pump extracts excess heat from indoors and sends it through the system, down into the earth where it is deposited, effectively lowering your indoor temperatures. If the heat transfer process is hindered in some way, your geothermal system may not be able to provide you with the cooling you need.

Why isn’t my geothermal system cooling?

1. Lack of air flow:

To facilitate heat transfer, there must be adequate air flowing through the heat pump. Air flow is commonly restricted by dirty, clogged air filters within the system. As contaminants pile up on the air filter, air movement is reduced and the air volume within the system can fall, preventing heat transfer.

2. Compressor malfunctions:

A geothermal heating and cooling system’s compressor works to pressurize the system’s refrigerant to facilitate proper heat exchange. If the compressor is not operating correctly, the coolant will not reach the necessary pressure to absorb and transfer heat from indoors to below ground.

3. Geothermal system leaks:

Leaks within the heat pump’s refrigerant lines or the geothermal system’s ground loop can prevent cooling. System leaks can allow refrigerant levels to drop, inhibiting the geothermal system from transferring heat properly to cool your home or business.

If your Lexington geothermal system isn’t keeping your home or business sufficiently cool this season, call Climate Control right away.
