The Hidden Culprits Behind Mini Split Performance: Sizing mistakes and Installation Mishaps
Beyond the obvious issues that plague mini split systems, two critical factors often lurk in the shadows: improper sizing calculations and sloppy installation practices.Many contractors rush through the sizing process,using rough estimates rather than conducting proper load calculations. This oversight can result in units that are either too powerful, leading to short cycling and humidity control problems, or too weak, struggling to maintain comfortable temperatures during peak demand.Think of it like trying to wear shoes that are two sizes too big or too small – you’ll definitely notice the discomfort!
Even with perfect sizing, installation blunders can sabotage your system’s performance. Here are the sneaky installation mistakes that might be affecting your comfort:
- Incorrect refrigerant line length causing efficiency losses
- Poor condensate drain slope leading to water damage
- Inadequate mounting brackets that create excessive vibration
- Kinked or improperly insulated refrigerant lines
- Electrical connections that don’t meet local codes
| Sizing Error | Impact |
|---|---|
| Oversized Unit | Short cycling, poor dehumidification |
| Undersized Unit | Constant running, inadequate cooling |
