Sizing and upgrade recommendations for Kent homes

Correct sizing is the most important factor in a successful mini-split replacement. Oversized or undersized systems both cause problems: short cycling, poor humidity control, higher energy use, and reduced equipment life. Green Head Heating follows a concise, transparent approach to determine the right system size and recommended upgrades:

1. Load assessment:

• Calculate the heat loss and heat gain for each room or zone, accounting for Kent-specific factors such as typical outdoor temperatures, humidity, window orientation, insulation levels, and occupancy patterns.
• Consider envelope improvements such as window upgrades or additional insulation, which can change sizing needs and improve long-term efficiency.

1. Zone planning:

• Determine whether single-zone, multi-zone, or hyper-zone configurations make sense based on room usage, traffic patterns, and comfort preferences.
• Recommend separate indoor heads for bedrooms, living areas, and frequently used spaces to enable precise temperature control.

1. Equipment selection:

• Match Mitsubishi indoor and outdoor models that meet calculated loads while maximizing SEER and HSPF. For homes where low-temperature heating performance is critical, select units with strong low ambient heating ratings.
• Recommend features such as enhanced filtration, whisper-quiet indoor units for bedrooms, or ceiling cassette heads for open-plan rooms.

1. Electrical and infrastructure evaluation:

• Verify that existing electrical service meets the new system’s startup and running amperage requirements.
• Assess refrigerant line runs and wall penetration plans to minimize visual impact and refrigerant loss.

1. Future-proofing:

• Where possible, recommend modular multi-zone outdoor units that allow adding zones later without replacing the outdoor unit.
• Consider smart controls and thermostat integrations to bolster convenience and efficiency.

This systematic sizing and upgrade planning results in a replacement that delivers comfort, reduces energy waste, and provides predictable performance in Kent households.
