01 · How it works

The VTAC: an air conditioner and a heat pump in a closet.

VTAC stands for vertical terminal air conditioner. Pick a mode, slide the temperature, tap the numbers.

Air conditionerIt moves the room’s heat outside through a louver in the façade.
Heat pumpIn winter it reverses the cycle; built-in electric heat of 2.5 to 10 kW takes over when needed.
Self-contained and verticalEverything fits in a closet: no compressor on the balcony, one thermostat per room.

It blows, but doesn’t cool anymore

It needs measuring: filter, coil, refrigerant charge or compressor. If it’s the compressor and the unit is less than 5 years old, the sealed-system warranty may apply; otherwise we compare repair and replacement.

Figures: maximum breaker (MOP) at 230 V from the 2023 Friedrich spec sheet. More electric heat means more comfort in extreme cold, but a bigger circuit. We check your panel during the estimate; our electricians do the wiring (RBQ licence 16).

R-410A or R-32?

The models in our catalogue (ending in RTP) use R-410A. Friedrich now builds the VERT-I-PAK with R-32 (ending in RCQ), with SEER2 and EER2 ratings.

For you: an R-410A unit can still be repaired. For a new unit, your estimate states in writing which generation we install.

12 · Fresh air

A VTAC cools and heats. To breathe, add an air exchanger.

The VERT-I-PAK’s fresh-air damper lets in 60 CFM at most. Click to see the difference.

The air exchangers we install

A VTAC conditions the air; it barely renews it. An air exchanger removes humidity and stale air and brings in fresh air while recovering the heat. We install both, and we wire them.

15 · Frequently asked questions

The questions we get about VTACs

What is a VTAC?
A vertical single-package air conditioner and heat pump: the whole unit fits in a closet against an outside wall. It draws in and rejects outdoor air through a wall sleeve and a louver, and blows conditioned air into the room through a short duct. You see them mostly in condos, hotels, seniors’ residences and student housing.
How much does VTAC installation cost?
The price depends on the capacity, the heat option, access (floor, elevator), the state of the closet and the number of units. We measure for free and send you a written estimate within 24 hours.
Which VTAC capacity should I choose?
Friedrich makes the VERT-I-PAK in 9,000, 12,000, 18,000 and 24,000 BTU, all on the same 23 × 23 in base. For a replacement, we start from your current model number; for a new installation, we size it on site for the room.
Does a VTAC heat in winter?
Yes. VERT-I-PAK VHA units are heat pumps with built-in electric heat. Friedrich rates the heat pump as the primary source down to 10 °F (-12 °C) on its recent models; the electric heat (2.5 to 10 kW depending on the model) serves as backup and emergency heat.
Is there a LogisVert grant for a VTAC?
No. Since November 26, 2025, LogisVert requires an ENERGY STAR certified heat pump, and VTACs are not certified. If you can switch to a certified wall or central heat pump, we show you the amount on the LogisVert page.
What warranty does a VERT-I-PAK have?
Friedrich covers the unit for 1 year, parts and labour, and the sealed system (compressor, coils, tubing) for 5 years. The warranty starts at installation.
My VTAC uses R-410A. Do I need to change refrigerant?
No, your unit can still be repaired. For a new unit, Friedrich has moved to R-32 (models ending in RCQ). Your estimate states which generation we install.
Does a VTAC bring in fresh air?
A little: the VERT-I-PAK has a passive outdoor-air damper, up to 60 CFM. For real ventilation with heat recovery, we add an air exchanger (vänEE, Venmar, Lifebreath, Fantech, GreenTek…).
Who does the electrical wiring?
We do. AirGreen holds RBQ subcategory 16 (electrical) on top of ventilation and refrigeration. The breaker size depends on the heat you choose (20 A for 2.5 kW up to 60 A for 10 kW, at 230 V).
Can you replace a VTAC from another brand?
Often, yes. We measure the closet, the wall sleeve and the louver on site. Friedrich offers an adapter for some First Company sleeves (9,000 and 12,000 BTU).
Can I keep my wall sleeve and louver?
Often, if they are Friedrich accessories in good condition: their dimensions have not changed from one generation to the next. We check on site; if not, we replace them in the same job.
Can you do a whole building?
Yes: from a few suites to the entire building (condos, hotels, seniors’ residences, student housing). We measure every closet, give you a written price and plan the work with the property manager.
What’s the difference between a VTAC and a PTAC?
A VTAC is vertical, in a closet, with a short duct. A PTAC is horizontal, under a window, and blows straight into the room. We install both: see our PTAC.
