The installation of an air-to-air heat pump (AHP) is an increasingly popular solution for heating and cooling homes, but it is not without risks if not carried out correctly. Poor installation can lead not only to malfunctions, but also to less-than-optimal performance and even early breakdowns. In this article, we look at the common mistakes made when installing an air-to-air heat pump, and how to avoid them.
1. Neglect unit size
One of the most common mistakes made when installing an air-to-air heat pump is not taking into account the appropriate size of the unit. If the unit is too small for the surface to be heated or cooled, it won’t be able to provide a comfortable temperature. Conversely, a unit that is too large could lead to excessive energy consumption and rapid wear and tear.
Why is this important?
Correct sizing of the heat pump ensures optimum energy efficiency and avoids continuous or short-term operation, which leads to premature component wear. To determine the ideal size, it’s necessary to carry out a precise calculation of your home’s thermal requirements, based on its surface area, insulation and orientation.
2. Choose an unsuitable location for the outdoor unit
The heat pump outdoor unit must be installed in a well-ventilated, unobstructed area. Many installations fail due to poor location, which can compromise system performance.
The consequences of a bad location
Incorrect installation can lead to rapid clogging of the system, annoying noises or poor air circulation. It is essential to ensure that the outdoor unit is installed at a sufficient distance from obstacles (walls, trees, bushes, etc.) and in a location where it will not be exposed to extreme conditions such as strong winds or snow.
3. Indoor unit incorrectly positioned
A common mistake when installing an air-to-air heat pump is to position the indoor unit incorrectly, especially in a room with poor air circulation. The unit must be positioned so that the air circulates freely and evenly.
How do I position the indoor unit?
Ideally, the indoor unit should be installed on an unobstructed wall, at a height sufficient to distribute the hot or cold air throughout the room. Avoid placing the unit close to heat sources, windows or behind curtains, as this may impair its efficiency.
4. Failure to insulate conduits properly
The pipes connecting the outdoor unit to the indoor unit must be well insulated. If the ducts are poorly insulated, you risk losing a large proportion of the energy generated, which can reduce the efficiency of your heat pump.
Why is duct insulation crucial?
Poor insulation results in heat or cold loss and additional energy costs. Insulated ducts help maintain the ideal room temperature without having to run the unit at full power.
5. Ignore the need for regular maintenance
Although the air-to-air heat pump is a relatively simple system to maintain, many users neglect regular servicing. An installation that is not properly maintained can see its performance plummet and its components wear out prematurely.
How can you avoid this mistake?
Be sure to clean the indoor unit filters regularly and check the outdoor unit coils for dust and debris. We also recommend that you call in a professional for a complete overhaul of the system once a year.
Conclusion
Installing an air-to-air heat pump requires special attention to avoid these common mistakes. By choosing a qualified professional and taking the time to properly size and install your system, you guarantee its efficiency, durability and low environmental impact.
