What is the lower temperature outside for heat pump? I prefer -16 F. Do you have 12000 BTU 1 outside and 1 inside wall mount unit?

This particular system will heat and cool down to -13Â°F outside temperatures.You can find the 12,000 BTU single-zone unit here: https://www.pioneerminisplit.com/collections/wys/products/pioneer-12-000-btu-21-5-seer-230v-ductless-mini-split-air-conditioner-heat-pump-system-full-set

How many amps to start and to run 18k btu wondering if it would run less amps once room is cooled

This system is rated 6.1A in cooling and 6.8A in heating. It is a soft-start system and the current does drop as the set temperature is reached since the compressor will shut off and only the indoor fan motor will keep running.

Is this unit 230 volt single phase?or Split? Also is a 230vac single phase available? And... Yes....I'm looking for 230 VAC single phase ... Off grid application in the USA... (Batteryless inverter applocation)

Yes, this is 230VAC, 60Hz, 1Ph.

How much distance is required between the outdoor unit and a 150 gallon propane tank with associated gas supply line?

For that we would recommend a 10 foot minimum.

Open rec room. metal building, florida 2 inches closed cell foam insulation. 11 foot walls. what do you suggest?

We would need the square footage to provide accurate BTU recommendation.

HOw many square ft will the 18,000 handle or the 12,000. Thank you in advance.

For typical applications, the 12,000 is meant to support up to 450 SQft and the 18,000 BTU is intended to manage up to 650 SQft.

Hello, I am looking at purchasing the 18,000 BTU Unit. If I purchase the 10 foot line rather than the 16 foot line will I need to remove some refrigerant and flare the line? Thanks

The amount of pre-charge is optimized for 16 ft, but any run between 5 and 25 ft will not require adjustment of the refrigerant levels. The 10 foot line will come pre-flared as well.

Can the outside unit be mounted on the wall?

Yes it can, you can use one of our wall-mounting brackets.

What size circuit breaker is needed for the 18000 BTU unit 208/230 volt single phase. Is it a double pole 15 or 20 amp.

Either is acceptable but we recommend 15A.

Can l install it myself and what would the cost be for something around 24000 btu.

You can DIY using the required tools and it comes with instructions to do so.ÂFor 24,000 BTU the equivalent unit would be this one: https://www.pioneerminisplit.com/collections/wys/products/pioneer-24-000-btu-20-5-seer-230v-ductless-mini-split-air-conditioner-heat-pump-system-full-set

I have an existing Pioneer 18,000 btu unit that will fail shortly because of coastal corrosion (60' from ocean). How can I make the external unit more corrosion resistant?

The most important component to protect against corrossion would be the coil. There are special sprays designated for this purpose such as this one: https://hvacmaintenanceproducts.com/coil-shield/

Can I replace an older 18,000 btu exterior unit (8 year old model) that has failed (due to corrosion) with a new unit and leave the existing inside unit or do I need to replace both? Can I use the same piping/hoses or do need to be replaced as well?

You would need to replace both units as a newer one would have a newer protocol that would not be backwards compatible with the old indoor unit. However you can most likely keep the same piping and lineset in place.

What size flare nuts on the 18000btu 22seer? I'm mounting to a brick wall, do you recommend the anchor bolts go in the grout line or the brick themselves?

It would have 1/4" and 1/2" line which corresponds to wrench size of 5/8" and 15/16" for the flare nuts. We would recommend to drill into the brick for this kind of heavy item as it is stronger than the mortar.

How many square feet would this unit efficiently heat/cool?

This system is recommended to manage spaces between 400 and 700 square feet.

What diameter hole should be drilled through the wall for the drain and tubing?

A 2.5" wall hole would be sufficient.

What gauge wire is required for the 18000 mini split?

This system would take a 20A double-pole breaker with 12 AWG wire. 2 hots and a ground, no neutral.

Iâ€™m trying to cool two rooms that share a wall. Can I hook up two interior units to one exterior unit.

This is a single-zone system meaning 1 to 1 outdoor to indoor unit. For dual-zone, you would need to check our multi-zone section. Use our matching table to find a suitable combination.

I have a mobile home that is 980 ft with new windows and fair insulation in pierce county Washington what size btu should i use

Generally we recommend 24,000 BTU for spaces between 600 and 1,000 sq ft.

Can we order just a line set? Amazon sells this exact unit for constable less money including 16' line. We need 25' . Do you price match? Would prefer buying from you rather than third party

Yes, we can price match. But our prices are identical across all retailers...double check the model number to assure it is the same. Please provide us the better price so we can match.

What are the copper pipe diameters if I want to pre-order for in wall installation

This system uses 1/4" and 1/2" size copper pipes.

what is include with this unit

is $1,32800 the total price

That is price before tax, but includes shipping.

Hi there I m planning on buying multi and single units together. I live in PA and the weather drops to 20s freezing cold. Would these units still work or it would freeze outside?

This system will continue heating down to -13Â°F outside temperatures. The multis as well.

Are any of the units wifi capable or capable of using a standard thermostat?

All systems are WiFi-capable, we offer wired programmable thermostats as well. Many options available for integration with smart systems.

What gauge wire is required from the main electrical panel to the disconnect box. 10-2 or 10-3?

It would need a 20A double-pole breaker and 12 AWG wire (2 hots+ground, no neutral).

What size wire do I need and what size beaker for this unit?

This would take a 20A double-pole breaker. The corresponding wire would be 12 AWG, with 2 hots and a ground, no neutral.

Can a second zone be added later?

No, for that you would need to shop for Multi-Zone systems: https://www.pioneerminisplit.com/collections/multi-split-systems

Which 18000 unit will still work without freezing up in below freezing temps?

Yes, this system will continue heating down to -13Â°F outside temperatures in heating mode.

Does this unit have a panheater

Yes this has a drain base-pan heater in the condenser unit to allow the system to continue heating down to -13Â°F outside temperatures.

You the breaker 30 amp and the wire 10/3

This would take a 20A double-pole breaker. The corresponding wire would be 12 AWG, with 2 hots and a ground, no neutral.

Are there any Wi-Fi add on for the 18k units?

Yes you would need this module: https://www.amazon.com/dp/B01I4P8B8A

What voltage can this operate at? Will it work with normal residential single phase 220/240 in the USA? Please list min and max voltage. I can decide if my service can stay with in those limits.

Yes it can. Min voltage 187, max is 253.

At the lowest outside temps this unit is rated for whatâ€™s the temperature coming off the indoor coil in heat mode ? I live in the north east part of the US and get asked about these all the time .

Depends on the current indoor temperature. A 20-25 delta-T (return vs supply air) is normal.

Is there a problem with the evaporators developing leaks of refrigerant after a couple of yes? Have a 24000 thatâ€™s gone bad because of that. I want to replace that unit but I have three more of your units that are fine so far but want to know how to protect them before I order a replacement unit . Will do what ever maintainence needed if I could find out how to do. Would appreciate your response. Thanks

Generally a monthly filter cleaning and a seasonal deep cleaning of the coil, blower, and inner shell is best for longevity of the system. Sometimes the indoor unit gets corroded and springs a leak for odd reasons of external factors. It can be caused by such things are Chinese drywall, air purifiers with ozone, even one customer had one due to making kombucha in the room.
