Mini Split Air Conditioning

Turn off power, open the indoor unit, remove the washable filter, rinse with lukewarm water, let it dry completely, then reinstall.

Installation costs vary widely by region, model capacity, and job complexity; expect a range rather than a fixed price.

Inverter units vary compressor speed for precise temperature control and higher efficiency; non-inverter units run at fixed speed.

Mini-splits are ideal for zoned cooling, retrofits and where ducts aren’t feasible; central systems suit whole-house conditioning when ducts already exist.

Estimate required BTU by room area and usage — roughly 9,000 BTU for small rooms (~100–150 sq ft), 12,000 BTU for medium rooms, etc.

Common causes are dirty filters, blocked outdoor airflow, low refrigerant, incorrect mode/settings, or a failing compressor.

Modern mini-splits typically use R32 or R410A; some low-GWP models offer R290 (propane) with special safety requirements.

Indoor unit noise varies by model but can be as low as ~18 dB(A) at minimum fan speed for quiet models.

Have a qualified technician service the system at least once per year; twice a year is recommended in heavy-use climates.

Turn off power, clean filters, protect the outdoor unit from debris and heavy snow, and follow manufacturer guidance for long-term storage.

With proper maintenance, split systems commonly last 10–15 years; heat pump components and compressor life vary by use and care.

Compressor replacement costs depend on model and region; it is often expensive and sometimes approaches the cost of a replacement unit.

Yes. Efficiency is measured by SEER (cooling) and HSPF (heating) ratings; higher SEER means lower energy consumption.
