Model code 53QHET30DN-708F explained
The code is not random; reading it lets you make sure you are comparing the same model at any seller (per the brand's Egyptian models):
- 53 = the Carrier Egypt model prefix
- Q = cool & heat (heat pump)
- 30 = cooling capacity in thousands of BTU (30,000 BTU/hr ≈ 4 HP)
- DN = DC inverter compressor
How much space does 4 HP cover?
Using our approved heat-load method (length × width × height × a factor of 300 / 350 / 400 BTU/m³ depending on exposure), this capacity covers 27 to 36 m² at a 2.8 m ceiling. Used in large halls, receptions, shops, small showrooms and meeting rooms. At this size the unit's position and airflow direction change perceived cooling more than extra capacity does. Large glazing, a kitchen and the number of occupants raise the load, so confirm with a real calculation: how engineers pick the right AC capacity · what HP and BTU mean · the AC calculator.
Operating mode and compressor
Besides cooling, this model heats in winter (heat pump): one unit for both seasons instead of buying a separate heater, and at much lower consumption than a heater.
With an inverter compressor the unit does not keep cutting out and restarting; it holds a low speed that keeps the temperature stable. That narrows the gap between the temperature you set and the one you feel, and keeps it quieter at night.
The Carrier Optimax Inverter series
Optimax with an inverter compressor, offered only in the large capacities (4 and 5 HP). R410A, cool & heat, aimed at halls and shops that run long hours. Our range has 2 models in this series from 4 to 5 HP, and this model is the smallest capacity in the series. All models are in the Optimax Inverter category · all Carrier prices.
Who is this model for?
This model makes sense if the unit will run long hours every day (a bedroom all night or an office all day), and the space is 27 to 36 m² with an external wall close by for the pipe route. If your situation is different, the comparison table below shows the closest alternative with its exact price difference.

Before choosing, look at these numbers: each row is a real alternative in our range with its price difference from this model in EGP and percent. Click a code to open that model's page.
The cheapest Carrier 4 HP wall-mounted split in our range is 53QHET30N-708F at EGP 68,676; this model costs EGP 10,874 more for the inverter.
Cost per 1,000 BTU
A simple measure that compares prices fairly: divide the unit price by its rated capacity. 53QHET30DN-708F costs EGP 79,550 for 30,000 BTU, which means 2,652 EGP per 1,000 BTU.
| This model | EGP 2,652 per 1,000 BTU |
| Average across our wall-mounted split range (44 models) | EGP 1,971 |
| Cheapest model of the same type | EGP 1,570 |
| Most expensive model of the same type | EGP 2,652 |
Cost per unit of cooling here is 35% above average, which is expected because you are paying for the inverter and heating and the series level. If that number matters most, the comparison table above has the cheaper options.
Installation and execution with El Shora
Installing a wall split takes one day if the space is ready. What matters: nothing blocking the indoor unit's airflow, an outdoor unit in a ventilated rather than boxed-in position, and a drain running outwards with slope and no back-fall.
What decides a unit's life is not the brand alone, it is the installation: copper at the right diameter with no extra joints, full insulation on both lines, a dry-nitrogen test and a micron vacuum before the refrigerant is released, and a correct drain slope. Every step is photographed and logged on our system under the project name. Details in AC installation · AC maintenance.
The unit price includes delivery only within our service areas; installation, commissioning, warranty activation and after-sales service are a separate paid service, written clearly in the quotation together with any extra pipe length, preparation, chasing or scaffolding the site needs.

FAQ about the Carrier Optimax Inverter 4 HP Cool & Heat Split AC
How big a room does the Carrier Optimax Inverter 4 HP Cool & Heat Split AC cover?
This capacity (4 HP ≈ 30,000 BTU) covers 27 to 36 m² at a 2.8 m ceiling, based on 300 to 400 BTU per cubic metre. On a top floor or a sunny façade treat it as the minimum, and you can check with the AC calculator.
What is the price of the Carrier Optimax Inverter 4 HP Cool & Heat Split AC today?
EGP 79,550 for the unit including delivery only within our service areas (updated 12 September 2026). Installation, commissioning, warranty activation and after-sales are a separate paid service, written clearly in the quotation before any work.
Does this unit need a special power supply?
No. It runs on single-phase / 220 V, the normal apartment supply, with no meter change. The run from the meter to the unit and any electrical work are priced separately.
Can I buy the unit and have someone else install it?
Of course; the price covers the unit and delivery only. Keep in mind that installation quality is what actually decides the compressor's life: the nitrogen pressure test, micron vacuum and full insulation are not cosmetic details, and warranty activation happens at commissioning.
Where do you deliver and how fast?
Delivery is included within our service areas in Cairo, Giza, the new cities and the coast. Because the warehouse is in 6th of October, deliveries to October, Zayed and nearby areas are scheduled faster, and in every case we confirm the appointment before dispatch.
What is the maximum distance between the indoor and outdoor units?
Per the manufacturer catalogue for this model: a maximum pipe run of 50 m and a maximum height difference of 25 m, with gas 5/8" and liquid 3/8" lines. Exceeding these reduces cooling and loads the compressor. The full table is at the pipe size page.
Where we deliver and install
Supply, installation and maintenance run from our base in 6th of October, with appointments confirmed before the visit and photo documentation. Among the areas we serve: AC in Madinaty · AC in New Alamein · AC in New Zayed · AC in Heliopolis · all service areas.
