Kaisai is a Polish air conditioner brand from FG Poland with a solid reputation for value and reliability. If you’re looking for a Kaisai air conditioner in Varna, Svit Komfortu stocks the available models with delivery and certified installation in Varna and the surrounding area. On this page we explain honestly which series we offer, what rooms they suit, what they cost and what to expect from the brand. No marketing hype — just what we’ve seen in practice on real installations.
Why people choose Kaisai
The main reason is price. Kaisai gives you an inverter air conditioner with decent features for less money than Japanese brands like Daikin or Mitsubishi. For an apartment, office or rental villa where budget matters, it’s a sensible choice.
It isn’t a premium brand, and we won’t pretend it is. You won’t get the quietest compressor on the market or the longest warranty. But you will get an air conditioner that cools well in summer, heats in winter and doesn’t cost a month’s salary. For most households in Varna, that’s exactly what matters.
The second reason is availability. Kaisai is one of the more widespread brands in Bulgaria, spare parts are easy to find and servicing is no problem. That isn’t always the case with more exotic brands.
R32 refrigerant — what it means for you
All current Kaisai series use R32 refrigerant. In practice that means two things. First, less harm to the environment, because R32 has a much lower global warming potential than the old R410A. Second, better efficiency — in other words, less electricity for the same cooling.
For you as a buyer, the difference is small day to day, but it matters for servicing and for any future recharge of the system. R32 is today’s standard, and it’s good that Kaisai switched to it long ago.
Energy class and real-world consumption
Most Kaisai models are rated A++ for cooling and A+ for heating. That’s a good level for their class. In practice, a 12000 BTU inverter air conditioner with this rating, used sensibly in summer, adds only a moderate amount to your power bill — far less than an old air conditioner without an inverter.
Don’t trust precise promises of so many euros per month. Consumption depends on how many hours the unit runs, what temperature you set, how well the room is insulated and which way it faces. The inverter helps because it doesn’t keep switching the compressor on and off — it holds the temperature smoothly. That’s also why it uses less than older models.
Kaisai air conditioner series — which one for whom
The Kaisai range is broader than it looks at first glance. Here are the main series we offer and who they suit.
Kaisai ECO (KEX)
This is the entry-level series of complete sets — indoor plus outdoor unit. Prices start at around €470 for a 9000 BTU model and go up to about €1130 for the more powerful versions. Energy class A++ / A+. If you want a new air conditioner without unnecessary extras that simply does its job, ECO is the logical starting point.
Kaisai ICE (KLW / KLB) and GEO (KGE)
Wall-mounted inverters for the home built on a similar platform. GEO stands out with a more modern design and Wi-Fi control, if you like to switch the air conditioner on from your phone before you get home. Both series cover the most popular capacities from 9000 to 18000 BTU. For a standard bedroom or living room, this is the sweet spot between price and comfort.
Kaisai KWX
The widest capacity range — from 9000 all the way to 24000 BTU. If you’re fitting out a large living room or open-plan space, you’ll find a powerful enough model here. There are also separate indoor units for this series if you’re building a multi-split system with several rooms on one outdoor unit.
Kaisai BLACK PRO HEAT and WHITE PRO HEAT
This is Kaisai’s higher tier. The PRO HEAT series is geared toward stronger heating, which makes sense for Bulgarian winters. Prices are higher — from around €700 for 12000 BTU up to about €1320 for the top configurations. BLACK comes in a black casing, WHITE in classic white. If the air conditioner will be your main heat source, not just for summer, this series is worth a look.
Floor-standing (KFAU) and cassette (KCA4U)
Not every room suits a wall-mounted air conditioner. The floor-standing KFAU works for rooms with little wall space and lots of windows, or where you want heat to rise from floor level. The KCA4U cassette is built into a suspended ceiling and is a common choice for offices and shops. Both use R32 and come in capacities from 9000 to 17000 BTU.

Kaisai vs. AUX and Gree
People looking at Kaisai usually also compare it with AUX or Gree — the other two more affordable brands we carry. Honestly, the differences in this price range are small and often come down to the specific model rather than the brand.
Kaisai and Gree have a similar reputation for reliability. AUX is slightly cheaper and also does the job. If you’re unsure, look at the capacity, energy class and warranty of the specific model, not just the logo. You can also compare for yourself on the pages for AUX air conditioners and Gree air conditioners.
What capacity do you need
A rough rule of thumb by floor area, with standard ceilings of about 2.6 m:
- up to 20 m² — 9000 BTU
- 20–35 m² — 12000 BTU
- 35–50 m² — 18000 BTU
- over 50 m² — 24000 BTU or a floor-standing/cassette model
This is only a guideline. High ceilings, lots of glazing, south or west exposure and poor insulation push the numbers up. A room that bakes in the afternoon sun needs a more powerful air conditioner than a north-facing bedroom of the same size. An undersized air conditioner runs flat out all the time, uses more power and wears out faster, so it’s better to err on the high side than the low side.
For a more precise estimate, try the BTU calculator or give us a call and we’ll work it out together.
Kaisai air conditioner installation in Varna
An air conditioner is only as good as its installation. Even the most expensive unit will perform poorly if the lines are badly vacuumed or the outdoor unit is in the wrong spot. That’s why installation is no place to cut corners.
Standard installation includes mounting both units, up to a few meters of piping, vacuuming the system and commissioning. What raises the price: a longer pipe run, drilling through thick or reinforced concrete walls, working at height with an aerial lift, or concealing the pipes inside the wall. That’s why we do a free site visit before giving a firm price — so there are no surprises later.
Varna’s coastal climate
Varna is a seaside city, and that matters for air conditioners. Salty air corrodes outdoor units faster than inland. On apartment blocks near the sea, we’ve seen outdoor units rust noticeably sooner. So for coastal installations we recommend anti-corrosion treatment of the outdoor unit and we’re careful about where we place it, ideally out of the direct sea wind. Learn more about the service on our page for air conditioner installation in Varna.
Maintenance and service
An air conditioner isn’t something you install and forget. The indoor unit’s filters should be cleaned every few weeks during the active season. It takes five minutes and protects both the air quality and the efficiency. A clogged filter means weaker cooling and a higher bill.
Once a year it’s a good idea to have maintenance done — checking the pressure, cleaning the heat exchanger and inspecting the drainage. In Varna this is even more important because of the salty air and the dust. Regular maintenance extends the unit’s life and keeps the factory warranty valid, since most manufacturers tie it to proper use.
Warranty
Kaisai air conditioners are covered by the manufacturer’s factory warranty. Separately, we guarantee the installation itself — if the problem comes from the installation rather than the unit, we fix it at our expense. The exact factory warranty terms depend on the model and we confirm them at purchase, because there’s no point publishing a number that might change tomorrow.
Delivery and service areas
We deliver and install in Varna and the surrounding areas. When the model is in stock, we can usually arrange delivery and installation within 24–48 hours. For more specific configurations or multi-split systems, it may take longer, because sometimes we’re waiting for a particular unit. We’ll give you the real lead time when you order, not an optimistic forecast.
How to order
The easiest way is to call +359 88 639 2424 and tell us which room you want to air-condition. We’ll recommend a capacity and a few models within your budget. If you prefer, browse the available Kaisai air conditioners or all air conditioners in Varna yourself and tell us which one you like. Then comes a free site visit, a firm price and installation.
Inverter or non-inverter — why it matters
All the Kaisai air conditioners we offer are inverter units. That’s not a marketing buzzword but a real difference in how they work. An old non-inverter air conditioner works like a light switch — it runs the compressor at full power until it reaches the set temperature, then shuts it off, then switches it on again. That’s why the temperature swings, you can hear the unit starting and stopping, and the bill is higher.
An inverter instead slows the compressor down and has it hold the temperature smoothly at low speed. The result is steadier comfort, quieter operation and noticeably lower power use, especially when it runs for long stretches during the day. Non-inverter models are cheaper to buy, but within a few seasons the difference in electricity usually eats up the savings. For a home where the air conditioner runs regularly, an inverter is almost always the right choice.
Kaisai multi-split systems
If you want to air-condition several rooms, you have two options. One is a separate air conditioner for each room. The other is a multi-split — one larger outdoor unit connected to two, three or more indoor units.
A multi-split makes sense when the facade is an issue. On many buildings in Varna, the homeowners’ association or simple aesthetics won’t allow five outdoor units hanging outside. With one outdoor unit, the problem shrinks. The cost per room isn’t always lower, and if the outdoor unit fails, all the indoor units stop at once — so it isn’t a universal solution. For most apartments with one or two rooms, separate split systems remain the simpler and cheaper option. The KWX series offers suitable indoor units for multi-split configurations if you decide to go that way.
What standard installation includes
By „standard installation“ we mean specific things, not a vague promise. It includes mounting the bracket and the indoor unit, placing the outdoor unit on a wall or on the ground, up to a few meters of piping between the two, connecting the lines, vacuuming the system, electrical connection to a nearby point, and commissioning with a performance check.
What falls outside the standard depends on the specific site — a pipe run longer than the included meters, concealing pipes in the wall with chasing and replastering, aerial lift work on high floors, running a new electrical line from the panel, or more complex bracing for the outdoor unit. We spot all of this during the site visit and price it upfront, so you get one clear price instead of paying extra on the day.
Common mistakes when choosing and installing
After many installations, the same mistakes keep coming up. The first is the wrong capacity — people buy 9000 BTU for a large living room because it’s cheaper, and then the air conditioner can’t keep up and runs at max all the time. The second is skimping on installation — a cheap installer without a vacuum pump who „purges with refrigerant,“ which shortens the system’s life.
The third is a bad spot for the outdoor unit — in direct midday sun or squeezed into a recess with no airflow, which cuts efficiency. The fourth, especially in Varna, is lack of maintenance — nobody cleans the filters or does the annual service, and then people wonder why the unit weakens after three summers. And the fifth is buying online only, without installation, which leaves the warranty in limbo, because manufacturers often require installation by an authorized company.
Noise and comfort
In a bedroom, noise matters as much as cooling. Kaisai inverters run more quietly than old non-inverter models because the compressor rarely runs at full speed. Most also have a night mode that lowers the speed and raises the temperature slightly toward morning so you can sleep undisturbed.
Here, too, the installation spot matters. An indoor unit above the bed blows straight down and is often annoying — it’s better above the door or on a side wall, so the air spreads out instead of falling right on you. It’s a small detail we sort out during the site visit, but it makes a big difference to comfort.
Why buy from a local company, not just online
Online, an air conditioner sometimes looks cheaper. But an air conditioner isn’t a TV — you don’t just unbox it and plug it in. It needs installation with specialized equipment, and later servicing. A unit bought online without installation often means you have to find an installer yourself, pay for installation separately and take the risk that the warranty won’t apply.
With a local company you get an on-site visit, one point of contact responsible for both the unit and the installation, and nearby service if anything goes wrong. Plus advice from someone who knows Varna’s climate and understands why an outdoor unit by the sea needs extra protection. That’s hard to buy online.
Seasonal use — summer and winter
In summer, a Kaisai air conditioner cools and dehumidifies the air, which with Varna’s humidity is sometimes more important than the temperature itself. Don’t keep it at 18°C — a difference of more than 6–7 degrees from the outdoor temperature is unhealthy and raises the bill for no reason. 24–25°C is usually enough for comfort.
In winter, inverter models heat at outdoor temperatures down to -25°C, and the PRO HEAT series cope especially well in the cold. In the shoulder seasons, an air conditioner is often a cheaper way to warm a single room than turning on the whole central heating. The only thing we ask of you year-round is to clean the filters — the rest is our job.
Kaisai air conditioners for offices and retail spaces
For commercial spaces, the math is a bit different than for a home. Here the unit runs all day, every day, so energy efficiency and reliability matter more than the sticker price. The KCA4U cassette is built into a suspended ceiling and distributes air evenly in four directions, which is convenient for an office with desks or for a shop. The floor-standing KFAU suits restaurants and spaces with lots of glass.
For a larger area or several rooms, a multi-split or several more powerful units from the KWX series often make sense. If you’re fitting out an office or retail space in Varna, it’s best for us to come and take a look — unit placement in a commercial space is planned differently than in an apartment, and a mistake here is felt every working day.
How long a Kaisai air conditioner lasts
With normal use and regular maintenance, a quality inverter air conditioner easily lasts over ten years. Kaisai is no exception — the compressor and electronics are good for their class. What shortens its life is almost always one of three things: lack of maintenance, poor initial installation, or constant operation at maximum because the unit is undersized.
In Varna, we add salty air to the list. An outdoor unit without anti-corrosion protection near the sea ages visibly faster. That’s why a small investment in protection at installation pays off with years of extra life for the unit.
Payment and delivery
We accept cash and bank transfer, and installment payments are available for some models — ask about current terms when you order. Delivery in Varna is usually fast for in-stock models. We also arrange delivery and installation in nearby towns and villages; only the travel to more remote addresses may add to the lead time and price. We’ll tell you upfront.

Frequently asked questions
What country is the Kaisai brand from?
Poland. It’s made by FG Poland. It isn’t Japanese, although it’s sometimes advertised with „Japanese quality,“ which is marketing, not fact.
Do Kaisai air conditioners work in winter?
Yes. Most inverter models heat at outdoor temperatures down to -25°C. The PRO HEAT series is specifically designed for stronger heating.
What refrigerant do they use?
R32 in all current series — an eco-friendly and efficient standard.
How much does a Kaisai air conditioner with installation cost in Varna?
Units start at around €470 for an ECO series set. Installation is priced separately depending on the specific job and confirmed after a free site visit. See also installation prices.
Kaisai or Gree — which should I choose?
In this price range the difference is small. Look at the specific model, capacity and energy class, not just the brand.
Do they have Wi-Fi control?
Many series, including GEO, support control from your phone. On more basic models, Wi-Fi may be an option with an external module.
How often should the air conditioner be cleaned?
Filters every few weeks during the season. Full maintenance once a year — and in Varna, because of the salty air, this is especially recommended.
Can I install the air conditioner myself?
We don’t recommend it. Installation requires a vacuum pump and know-how, and a mistake usually shortens the unit’s life and often voids the factory warranty.
How long does a Kaisai air conditioner last?
With regular maintenance and proper installation, easily over ten years. Varna’s salty air is the main reason outdoor units age faster, so we recommend anti-corrosion protection.
Can you deliver outside Varna?
Yes, we also serve nearby towns and villages. Travel to more remote addresses may add to the lead time and price, which we’ll confirm in advance.
Do you offer installment payments?
For some models, yes. Ask about current terms when you order; we accept cash and bank transfer.
