About the GLZS4MA1810

Where the GLZS4MA1810 fits

A heat pump is an air conditioner that can run in reverse: in winter it pulls heat from outdoor air and moves it inside, which is far cheaper than resistance heat in most of the country. The GLZS4MA1810 pairs with a matched indoor coil or air handler, and in cold climates it is often installed dual-fuel with a gas furnace that takes over below the balance point.

Inverter (variable-capacity) heat pumps modulate output to match the load, which keeps the house closer to setpoint, runs quieter and pulls the best efficiency numbers; single-stage units cost less up front and are simpler to service. Both need a matched indoor coil to hit their ratings.

Background reading: the U.S. Department of Energy heat pump guide.

What to check before you order

• Tonnage from a load calculation; SEER2 and HSPF2 for your climate.
• Matched indoor coil or air handler with the same refrigerant (AHRI-listed pairing).
• Thermostat with an O/B reversing-valve terminal, or a dual-fuel thermostat if pairing with a furnace.
• Electrical service, pad, disconnect and line set (sold separately).

Installation and service notes

Outdoor heat pumps sit on a pad raised above snow and grass level with clearance for defrost water to drain, a disconnect within sight, and a line set sized and run within the manufacturer’s length and lift limits. Commission it in both heating and cooling modes and confirm the reversing valve and defrost cycle operate before you leave.
