Geothermal System Repair, Installation, and Maintenance Services

R&D Heating and Cooling provides a full suite of repair, replacement, installation, and maintenance services for geothermal systems.

Geothermal System Repair Services

Geothermal systems are relatively low maintenance, but mistakes in the installation process can lead to complications down the road.

At R&D HVAC, we have years of experience repairing geothermal systems. We perform thorough testing and evaluation on the way a system works before performing any repairs.

R&D HVAC Geothermal System Services:

Geothermal System Replacements

Changes in the environment may call for the replacement of a geothermal system. We advise opting for a replacement when the price of repairs is at least a third of the value of the entire system.

Geothermal System Installations

Geothermal systems can be difficult to install. R&D HVAC technicians have the know-how, certification, and equipment to provide a quality installation.

Once installed correctly, eco-friendly geothermal systems can last for—literally—generations.

Troubleshooting Your System

If your geothermal system’s heat doesn’t seem to be working, we recommend checking the following to see if you can get your system up and running before contacting the professional services of R&D HVAC.

Troubleshooting Checklist

  • Check Your Thermostat — Is it on the correct setting?
  • Check Your Filters — Are your filters dirty or clogged?
  • Check Your Power Source — Is your system getting electricity?

If your thermostat is at the correct setting, your filters are clear, and the electrical connection to your heating system is online and your geothermal system is still not working, contact R&D HVAC to get your heat back on today.

Geothermal System FAQs and Information

  • How do geothermal systems work?
  • Geothermal heat pumps, also known as geothermal heating systems, are a type of low-energy and eco-friendly heating (and cooling!) system that distributes heat from beneath the ground into your home through a series of pipes. These systems are able to run very quietly.

  • How do I maintain my geothermal system?
  • Geothermal systems should be serviced annually. Periodic checks to the air filter and drain, and annual coil cleanings are advised for maximum performance. The water pump filter should be cleaned every three months.

  • Geothermal System Installation
  • Geothermal systems can be installed vertically or horizontally, depending on the environment. This means that installing a geothermal system doesn’t have to take up a lot of space, as the outside pipes and components are buried.

  • What can I expect with a geothermal system installation?
  • Geothermal systems are rather complex and can broke down into two distinct phases. The first phase involves drilling and installing the loop field. The second phase consists of installing the geothermal heat pump equipment, and tying everything together.

  • What are some things I can check if my system isn’t working properly?
  • Geothermal systems are essentially heat pump systems. As such, they are susceptible to the same types of problems and repair issues. The difference in a ground source heat pump, or GHP, is that it has a loop system in the ground which uses water to extract heat, as opposed to air in a traditional system. As with most heating systems, maintenance is the key to preventing heating problems. There are a few basic things that can be checked, however, if you feel that your geothermal system is not working correctly:

    • Does the system have power?
    • Check the system to ensure it is, in fact, on Most systems will have some form of power indicator on the air handler. Another simple test is to set the thermostat to a higher temperature, and listen for the unit to turn on. If the system appears off, look for the emergency shut of switch, most likely mounted to the unit. Make sure the switch is in the on position. The next step is to check the breaker in the electrical panel to ensure that it has not been tripped.

    • To the thermostat!
    • Does the thermostat have something on the screen? Is it set to “Heat”? If your answer is no to either of these, we have found the problem. Make sure the unit is set to its “Heat” mode. If there is nothing on the screen, refer to your manual for how to replace the batteries. If the thermostat is hard wired, the issue is more in-depth and you need to R&D HVAC for service.

    • Check the air filter
    • If your air filter is clogged, you will have minimal air flow. This could cause the system to shut down. It’s best to change your air filter once a quarter.

    • Do you see water?
    • If there is water in the pan under your air handler, you can remove the water from the pan. Assuming you have an emergency shut-off switch ,that should allow the unit to start, providing a temporary solution. After that, you need to contact our office for service, as the problem will continue to occur until the underlying issue is addressed.

  • What are some common issues that may require repair services?
  • There are a few issues that can occur with a geothermal heat pump that will require service:

    • Clogged water pump filter
    • The best way to handle this is to have your geothermal system serviced annually. And the water pump filter should be cleaned every three months, if possible.

    • Bad reversing valve
    • The reversing valve is what allows your heat pump to switch from cooling to heating. Sometimes, the valves become stuck, or fail altogether, requiring replacement.

    • Low refrigerant
    • Much like their traditional heat pump counterparts, geothermal systems use refrigerant, albeit through heat exchange by water as opposed instead of air. Low refrigerant will cause the system to cool off before the system can extract the heat.

    • Bad compressor
    • Geothermal systems are an all-in-one system, with the compressor located in the indoor unit, as opposed to outside. Depending on how the unit is maintained, or how old the system is, the compressor may fail and require replacement.

  • Do I need to have a back or front yard to have a geothermal system?
  • A geothermal system needs some ground in order to run the “loops”. The size of your yard, whether front or back, can be an issue to installation. The size of the system dictates the size of the “loop field.” The loops themselves can be drilled deeper to minimize the amount of yard used, or the loop field can be larger horizontally to accommodate issues with drilling depth.

  • How long can I expect my geothermal system to last?
  • Most geothermal systems are rated to 25 years of life, if properly maintained.
