Understanding Heat Pump Condensers
Despite the name, a heat pump is an HVAC system component that can heat and cool the inside of your home. These systems help homeowners in mild climates avoid installing both a furnace and an air conditioner.
Heat pumps work by pulling heat from the air outside. During the colder months, heat pumps extract warm air from the cool air and transfer it indoors after going through a heating process. Conversely, during the warmer months, the heat drawn from the outside air undergoes a cooling process before being funneled into your home. Heat pumps are environment-friendly, unlike furnaces that burn fossil fuel.
A condenser is an essential part of a heat pump. The condenser is also referred to as an “outdoor coil.” Along with the evaporator, it is made of copper condenser pipes and aluminum fins. The condenser is where the heat exchange takes place.
How Does the Heat Pump Condenser Work?
First off, there is a liquid called the refrigerant that flows through the condenser system. During cooling mode, as heat is absorbed from the outside, surrounding air, condensation occurs as the refrigerant changes from a gas to a liquid, giving off cool air.
During the heating mode, the opposite is true. Thanks to the reversing valve, the refrigerant changes direction. As the condenser coil pulls heat from the air, it changes from liquid to gas. In turn, this provides heated air.
Benefits of Heat Pump Condensers
There are many advantages of a heat pump condenser. When your heat pump condenser is faultless and working at its best, you can expect the following:
- Better overall performance of the heat pump
- Longer lifespan of the condenser and the entire heat pump system
- Improved air quality within your home
- Better energy efficiency
Where To Place the Condenser Unit
If you want your condenser unit to work well and for an extended period, we strongly advise placing it outside, where there is a lot of fresh air. Ample air supply and general airflow ensure the condenser’s high efficiency.
Another good tip is to place your heat pump condenser away from direct sun exposure. If it is situated in direct sunlight, the excessive heat might subject it to damage. In addition, avoid placing your heat pump condenser under a tree due to falling leaves potentially clogging the unit.
Heat Condenser Problems and Their Solutions
Like all high-functioning electrical appliances, heat pump condensers are susceptible to several issues. However, they all have easy solutions. Here are a few common problems that heat condensers face.
- Overheating
If you notice an overheating problem, it is often caused by poor heat pump placement. For example, heat pump condensers placed under direct sunlight are susceptible to overheating. The heat pump could also have faulty sensors. You could move the pump yourself if it happens to be in the wrong place, but contact a professional for help if the problem is more technical. - Defective fan motor
Fan motor failure could be due to excessive dirt or debris. Dirt and debris can also cause overheating, giving you two problems at the same time. Contact our technicians to take a professional look at the fan and determine if it needs a replacement. In addition, consider electricity protection to curb an overheating problem. - Energy deficiency
It’s common maintenance practice to get your heat pump cleaned by a professional two or three times per year. Doing this clears the buildup that collects on the coils. Not remembering to do so could decrease your heat pump’s energy efficiency. Your unit could end up consuming up to 60% more energy and giving off almost 40% less heat!
Initial Steps To Correct a Failing Condenser
Here is an example of the step-by-step maintenance routine our technicians follow when a heat pump condenser appears to be failing:
- Switch off the power.
- Carefully clean the condenser area.
- Remove the outer piece.
- Unscrew the top grille.
- Spray the condenser with a garden hose.
- Assemble the elements as they were.
- Turn the power back on.
If these steps don’t correct the problem, our experienced technicians dig deeper to assess the cause of the malfunction.
