6 Best RV Air Conditioner Heater Combo in 2026: A Practical RV Guide

Six rooftop RV air conditioners that also heat, from 12V off-grid units to 115V heat pumps, compared by heating BTU, power input and fit.

By Bowen HigginsRV Editor at RV Gear Lab6 products comparedSpec-sheet researched

An RV air conditioner and heater combo only earns its place if the heating side is real: a stated heating BTU figure, an outdoor temperature range, and a power input that matches what your coach can supply. This guide treats the heat function as the deciding feature and sorts picks by how clearly each listing documents it.

The six picks split into two camps. Three Arsenda units and a Treeligo are 115V non-ducted heat pumps around 18,000 BTU cooling, while the Xenjum and Bailigo run from 12V DC with much smaller heating output, so the first job is choosing your power source.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: Arsenda RV Air Conditioner 18000 BTU leads this shortlist for Standard 115V roof swap. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are 18,000 BTU cool, 10,236 BTU heat, 18,000 BTU heat pump, R32, 18,000 BTU with heat pump. Confirm the exact model and included components before ordering.
Trade-off to plan for: Needs both 115V AC and 12V DC connections

Before you buy

What Matters Before You Choose an RV Air Conditioner Heater Combo

Key buying criteria so you get the right fit the first time.

01
Heating BTU on the listing
BTU is the unit of heat moved per hour, and a combo needs its own heating number, not just a cooling number. A unit with 18,000 BTU cooling and 10,236 BTU heating can warm a space meaningfully above freezing, while a 4,500 BTU heating figure is mild supplemental warmth. Look for a separate heating BTU in the title or opening lines.
02
Heat pump versus resistance heat
A heat pump moves heat from outside air, which works best in mild weather and loses output near freezing. Resistance heat uses electricity directly and is steady in any temperature but pulls far more power. Check whether the listing says heat pump, electric heat element or only generic heating.
03
115V versus 12V power
A 115V unit runs from shore power or a generator and needs a large breaker budget on a 30 amp coach. A 12V DC unit runs from batteries and suits off-grid, but long runs need a large lithium bank and heavy cabling. Read the voltage in the title and any note about needing both AC and DC connections.
04
Outdoor operating range
The rated outdoor range tells you when the unit will still run. A range such as 23 to 115 degrees F covers summer heat and mild winter use but not hard freezes. Compare the range with the lowest temperature you actually camp in.
05
Roof opening and weight
Most 115V units fit a 14.25 inch by 14.25 inch opening, while a few state slightly different sizes. A mismatch means sealing, trimming or adapters on the roof. Confirm the roof cutout size and the unit weight against your roof structure before ordering.
06
Control and noise details
Remote controls, app control, fan speed counts and dB ratings affect daily comfort. A 35 dB rating suits sleep better than a 50 dB rating, though ratings come from the seller. Look for stated dB numbers rather than the word quiet.

Detailed reviews

The 6 best rv air conditioner heater combo, explained

Best Documented Heating · 1 of 6

Arsenda RV Air Conditioner 18000 BTU

18,000 BTU cool, 10,236 BTU heat
110-120V, non-ducted
Fits 14.25 inch roof opening

Check price on Amazon

Best for: Standard 115V roof swap

Our take

Best for owners swapping a standard 14.25 inch rooftop unit who want a heat pump with the heating capacity printed on the page.

Why it made the shortlist

The Arsenda listing that states both numbers outright, 18,000 BTU cooling and 10,236 BTU heating, makes it the easiest combo in this list to judge on paper. It is a 110 to 120V non-ducted rooftop unit that fits 14.25 inch by 14.25 inch roof openings and lists operation from 23 to 115 degrees F outdoors.

Compared with the two other Arsenda listings, this one puts the heating BTU in the first bullet instead of leaving it implied. Against the Treeligo, it matches the cooling and heating figures while naming the 12V DC control connection plainly.

A good fit for shoulder-season trips where electric heat spares the propane furnace.

What works

Heating and cooling BTU both stated
Works from 23 to 115 degrees F outdoors
UV-resistant rooftop construction
Non-ducted design suits standard roof openings

Watch out for

Needs both 115V AC and 12V DC connections
Heat pump output drops in deep cold

Best Cooling and Heating Value · 2 of 6

Arsenda RV Air Conditioner 18000 BTU with Heat Pump and Cooling

18,000 BTU heat pump, R32
110-120V non-ducted
23 to 115 degrees F range

Check price on Amazon

Best for: Mainstream heat pump swap

Our take

Best for buyers who want a mainstream-sized heat pump combo and are happy to run a 12V feed to the unit as well as shore power.

Why it made the shortlist

This Arsenda 18,000 BTU unit is described as a heat pump with cooling, using R32 refrigerant on 110 to 120V power. It lists a 23 to 115 degree F outdoor range and fits the standard 14.25 inch roof opening.

It shares its core hardware and price with the other Arsenda listings above and below, so the choice among them comes down to which listing you trust. Against the Treeligo, it lists R32 refrigerant and the 12V DC requirement more openly.

What works

R32 refrigerant stated on the listing
Fits standard 14.25 inch roof cutouts
Rugged UV-resistant housing for travel
Operates from 23 to 115 degrees F

Watch out for

Heating BTU not shown on the listing
Requires 12V DC alongside 115V AC

Best Alternate Arsenda Listing · 3 of 6

Arsenda RV Air Conditioner 18000 BTU with Heat Pump and Cooling

18,000 BTU with heat pump
R32 refrigerant, 110-120V
Non-ducted rooftop design

Check price on Amazon

Best for: Arsenda buyers wanting stock options

Our take

Best for buyers who have already settled on Arsenda and want a heat pump rooftop unit without a long hunt.

Why it made the shortlist

The second Arsenda heat pump listing carries the same 18,000 BTU rating, R32 refrigerant and 110 to 120V non-ducted design. It uses the same 14.25 inch roof opening and 23 to 115 degree F operating range as the pick above.

Against the Treeligo, it lists the dual-power requirement up front.

What works

Same spec set as the sibling Arsenda
R32 refrigerant listed
Standard 14.25 inch roof fit
Wide outdoor temperature range stated

Watch out for

No separate heating BTU on the listing
Needs 115V AC and 12V DC together

Check price on Amazon

Best Quiet 115V Option · 4 of 6

18000 BTU RV Air Conditioner with Heat

18,000 BTU cool, 10,236 BTU heat
50 dB operation
Fits 14.17 inch vent opening

Check price on Amazon

Best for: Budget 115V heat pump

Our take

Best for budget-minded buyers who want 18,000 BTU of heat-pump capacity on shore power.

Why it made the shortlist

The Treeligo is an 18,000 BTU cooling and 10,236 BTU heating, 115V non-ducted rooftop unit rated at 50 dB. Its listing states a 23 to 115 degree F outdoor range and a fit for 14.17 inch by 14.17 inch vent openings.

Against the three Arsenda units, it undercuts them on price while matching the BTU figures and the 50 dB rating. Against the 12V units, it brings far more heating capacity.

What works

50 dB noise level stated
Heating capacity printed on the listing
Non-ducted design for quick install

Watch out for

Roof opening listed slightly under 14.25 inches
Needs shore or generator power

Check price on Amazon

Best 12V Off-Grid Combo · 5 of 6

Xenjum 12V RV Air Conditioner with Heater

11,000 BTU cool, 4,500 BTU heat
12V DC, 43 lbs
35 dB, 6.1 inch profile

Check price on Amazon

Best for: Off-grid 12V cooling and heat

Our take

Best for boondockers and van or small trailer owners with a large lithium bank who want a combo that skips the generator.

Why it made the shortlist

The Xenjum is a 12V DC rooftop unit rated 11,000 BTU cooling and 4,500 BTU heating, weighing 43 lbs with a 6.1 inch profile. It uses an inverter scroll compressor, lists 35 dB operation and comes with a remote control and LED panel.

Against the 115V Arsenda and Treeligo units, it trades heating capacity for battery operation and a much lighter body. Against the Bailigo, it gives clearer numbers on weight, noise and battery bank sizing.

Strong for quiet nights with a battery bank ready to feed it.

What works

Runs from the RV battery, no generator
Light at 43 lbs for solo install
Inverter scroll compressor, 35 dB stated
Remote and LED panel with six fan speeds

Watch out for

Heating output is much smaller than 115V units
Needs a large battery bank for long runs

Check price on Amazon

Best Compact 12V Budget · 6 of 6

9300 BTU Camper AC Unit with Heat 12V AC/Heater Unit

9,300 BTU, 12V DC
Frequency-adjusting inverter design
ABS body, accessory kit

Check price on Amazon

Best for: Vans and truck cabs

Our take

Best for tiny spaces, truck cabs and van builds where a low-draw 12V unit is enough.

Why it made the shortlist

The Bailigo is a 9,300 BTU 12V rooftop unit marketed as an AC and heater combo for campers and trucks. Its listing mentions an inverter-style frequency-adjusting design and an ABS body.

Against the 115V units, it serves very small spaces such as a camper van or truck sleeper.

What works

12V DC suits battery-only setups
Inverter-style design for lower draw
Includes accessories and instructions

Watch out for

Heating BTU is not given on the listing
Best for small spaces, not full trailers

The catch: Against the Xenjum, it costs less and is smaller in capacity, making it the entry-level 12V option.

Methodology

How We Built This Shortlist

Each pick was assessed across 5 criteria weighted for real-world use.

Heat function evidence

We compared whether each listing gives a heating BTU, a heat pump label or only a generic combo claim.

Power input

We separated 115V non-ducted units from 12V DC units and noted any extra 12V control requirement.

Outdoor temperature range

We noted stated operating ranges, since a heat pump loses output as outside air gets colder.

Roof fit and weight

We compared roof opening sizes and listed weights where given.

Noise and controls

We noted dB figures and remote or app control details printed on each listing.

Decision guide

Match an RV Air Conditioner Heater Combo to Your RV

By Power Source

Your situation	Recommended pick	Why
30 or 50 amp shore power, full-size trailer	Arsenda 10,236 Heat	Prints both cooling and heating BTU on the listing.
Cheapest 18,000 BTU heat pump	Treeligo 18K Heat	Matches the Arsenda BTU figures at a lower price.
Standard 14.25 inch swap, R32 refrigerant	Arsenda Heat Pump	R32 stated and fits the standard cutout.
Off-grid with a large battery bank	Xenjum 12V Combo	12V DC with 35 dB operation and a 43 lb body.
Camper van or truck cab on a budget	Bailigo 9300 BTU	Smaller 12V unit for tiny spaces.

By Budget

Budget	Recommended pick
$510 to $660	Bailigo 9300 BTU or Treeligo 18K Heat
$690 to $780	Xenjum 12V Combo or Arsenda 10,236 Heat
$770 to $780	Arsenda Heat Pump or Arsenda Heat Pump II

115V Heat Pump vs 12V Combo

115V heat pump

A 115V unit moves a lot of heat from shore power. The Arsenda 10,236 Heat, Arsenda Heat Pump, Arsenda Heat Pump II and Treeligo 18K Heat all sit here with 18,000 BTU cooling.

12V DC combo

A 12V unit runs from batteries with lower heating output. The Xenjum 12V Combo and Bailigo 9300 BTU sit here and suit small spaces or lithium banks.

Most trailer owners on shore power should start with the Arsenda 10,236 Heat; pick the Xenjum 12V Combo only if you camp off-grid with a big battery bank.

By Heating Priority

Preference	Recommended pick
Heating figure printed on the page	Arsenda 10,236 Heat
Quietest stated dB	Xenjum 12V Combo
Lowest cost for the 18,000 BTU class	Treeligo 18K Heat
Smallest footprint and draw	Bailigo 9300 BTU

For Spring and Fall Camping Specifically

Look for

Look for a stated heating BTU, an outdoor range down to at least 23 degrees F, and a heat pump label so cool mornings do not need the furnace, as the Arsenda 10,236 Heat listing shows.

In this comparison

The Arsenda 10,236 Heat lists all three on one listing, and the Treeligo 18K Heat matches it with a lower price tag.

When to Spend More

Spend more if

Spend more if you want the heating BTU stated plainly and a roof-ready 14.25 inch fit, which the Arsenda 10,236 Heat provides, or if you need true battery operation from the Xenjum 12V Combo.

Save if

Save if you only need mild warmth on shore power: the Treeligo 18K Heat gives similar BTU figures for less, and the Bailigo 9300 BTU is enough for a van.

FAQ

Before You Bring One Home

Is a heat pump combo worth paying more than a cooling-only unit?

If you camp in spring and fall on shore power, yes, because a heat pump adds electric warmth without burning propane. If you camp in winter below freezing, a heat pump alone will not carry you. Treat it as a supplement to the furnace.

How do I check the heat function before buying?

Look for a stated heating BTU, such as 10,236 BTU for the Arsenda 10,236 Heat or 4,500 BTU for the Xenjum 12V Combo. Also check the outdoor temperature range and whether the listing says heat pump or electric heat. If there is no heating number, treat the combo claim with caution.

Why do some listings say I need 12V as well as 115V?

The Arsenda listings state that the unit needs both a 115V AC supply and a 12V DC supply to operate. The 12V feed typically powers control functions. Check your roof wiring for a 12V connection before swapping.

Will an 18,000 BTU unit run on a 30 amp RV?

Start-up current is the issue. Use the listing's amp rating if provided, and consider a soft start kit on a 30 amp coach. Do not run it with other heavy loads on the same circuit.

What maintenance does a heat pump AC need?

Clean the filter every month in use and keep the roof coil fins free of debris. Check roof seals and mounting gasket once a season. Cover the unit during long storage.
