Speak HVAC without the jargon
- SEER2
- The current efficiency rating used to compare cooling systems — a higher SEER2 means the system uses less energy to cool. Which level makes sense depends on your home and budget; we're happy to talk it through.
- Heat pump
- A system that moves heat instead of making it — cooling your home in summer and reversing to heat it in winter, all with one piece of equipment.
- Ductless mini-split
- A small outdoor unit paired with one or more indoor units that heat and cool individual rooms without any ductwork.
- Zone
- An area of the home with its own temperature control. Each indoor unit of a mini-split system is its own zone.
- Ceiling cassette
- A ductless indoor unit recessed into the ceiling that distributes air in four directions — a discreet alternative to a wall-mounted unit.
- Package unit
- Heating and cooling combined in one outdoor cabinet, common on manufactured and mobile homes in our area.
- BTU
- British Thermal Unit — the standard measure of heating or cooling energy.
- Tonnage
- An AC or heat pump's cooling capacity. One ton equals 12,000 BTU per hour — it's about capacity, not weight.
- Condenser
- The outdoor half of an AC or heat pump, where collected heat is released to the outside air. It's the unit monsoon dust loves to coat.
- Air handler
- The indoor unit that moves air through your home — blower, coil and controls in one cabinet.
- Refrigerant
- The working fluid that carries heat between the indoor and outdoor units. Low refrigerant usually means a leak to repair, not a top-up to repeat.
- Evaporative (swamp) cooler
- A cooler that pulls hot, dry air through water-soaked pads — effective in dry desert heat, weaker during humid monsoon weeks.
