Homeowners with geothermal heat pumps understand how beneficial they are, especially regarding heating, air conditioning services, and energy consumption. You can use a geothermal heat pump to heat your home during the cold season and blow cool air into your home during those scorching summers. Better yet, geothermal heat pumps have an incredibly long lifespan. Although geothermal heat pumps require less maintenance, that doesn’t mean they don’t experience various issues. Unlike the issues with conventional HVAC systems, the problems that befall geothermal heat pumps are unique. This is particularly because they have several components not found in many HVAC setups. This article will explain the geothermal heat pump issues and how a Heating and air conditioning repair technician can resolve them.
Signs That a Geothermal Heat Pump Has a Problem
Before we turn to the problems that affect geothermal heat pumps, it is good to know the signs to watch out for when such issues arise. Below are some common signs that there’s something wrong with your geothermal heat pump, and it is time to have a heating and air conditioning service provider come over for a further inspection.
- Unusual noises or smells coming from the geothermal heat pump
- Lack of enough airflow
- High electricity bills
- Uneven cooling or heating of different areas of your home
- Visible water leaks on different components of the heat pump.
And when the heat pump doesn’t cool or heat your home, that is an obvious sign of a significant underlying problem.
Geothermal Heat Pump Issues
Improper Underground Loop Pressure
The great thing about geothermal heat pumps is that they usually heat your home during the cold season by drawing heat from underground. The ground is normally warmer than the surface or outside air on cold days. This makes the heat pumps heat your home extremely efficiently. However, the ability of a geothermal heat pump to heat your home in the cool season relies on the water within an underground loop absorbing the heat underground and transferring it into your home. Thus, the water pressure in the underground loop must be enough for the water within to get that heat into your home effectively. Further, the water should be able to absorb heat from your home and move away during the summer.
The geothermal heat pump won’t cool or heat your home properly whenever the pressure falls outside the manufacturer’s specified range. Hence, you must have a heating and air conditioning service provider recharge the loops to ensure the air inside your Plano, TX home is heated or cooled to a comfortable level. But what causes an improper ground loop pressure? These subterranean loops usually expand and contract because of the temperatures beneath. Hence, you may want to have your heating and air conditioning service provider inspect the loops regularly and refill them to ensure that the water inside is balanced.
Geothermal heat pumps, just like many conventional HVAC systems, make use of fans to move cooled or heated air through the ductwork. Some of your rooms may feel cool during cold months due to dirty air filters, punctured air ducts, or even poorly designed air ducts. Contaminants can spread throughout your home if your air filters or ducts are dirty. Headaches, sinus problems, eye discomfort, and other problems can be brought on by allergens such as pet dander, pollen, dust, and pest droppings. Ensure that you have an air conditioning service tech change the filters or clean the air ducts to avoid such issues.
Damaged Control Panel
The geothermal heat pump features a control with indicator lights that notify you in case of a problem. The irony of this is that the control panel could also develop issues. It could not be receiving enough electrical power or has short-circuited. Since this is among the main things that heating and air conditioning service providers rely on to determine if there’s a problem, you must ensure it is properly functioning. The lights on this panel are either high-pressure or low-pressure. Whenever either is on, that should signal you to call a heating and air conditioning service provider and have them inspect the heat pump. As explained above, the heat pump relies on water pressure in the underground loop system to heat or cool your Plano, TX home.
Dirty Air Filter
When was the last time you changed the air filters? If you cannot recall, maybe it’s time you have a heating and air conditioning service provider replace them and clean the air ducts. Dirty air filters can impact a geothermal heat pump. They starve the heat pump of air. The simplest way to describe this is that when there isn’t much air flowing through the system, there can’t be much heat transfer into the air. Your geothermal system may occasionally merely have a filthy air filter as an issue. Clean it or replace it per the manufacturer’s instructions.
Malfunctioning Blower Fan Motor
Geothermal heat pumps also feature a blower motor fan responsible for blowing the conditioned air. If the blower fan motor is faulty or damaged, your Plano, TX home will not have sufficient conditioned air. Since dirty is the main reason why blower fan motors malfunction, it is critical that you have a heating and air conditioning service regularly. The technicians can catch any developing issues before they become full-blown. However, blower motors also may fail due to electrical failures, age, and other internal problems in the heat pump. Hence, you should have an HVAC pro inspect, fix or replace the blower fan if damaged. The same goes for any other component of the geothermal HVAC system.
Follow a Routine Geothermal Heat Pump Maintenance
Although geothermal heat pumps last longer and require fewer repairs, that doesn’t mean they don’t need maintenance. Most of these issues can be prevented through maintenance. Contact us at One Hour Air Conditioning & Heating of Dallas for geothermal heat pump inspection and servicing.
