Yes, private residential construction is one of our core competencies. Whether you want to retrofit an existing single-family home, air-condition a condominium, or plan an energy-efficient new build – we offer tailored solutions for your home.

Absolutely! The switch to a modern heat pump, in particular, is heavily subsidized by the state (e.g., via KfW). We will advise you in detail beforehand on the current funding guidelines and support you in securing the maximum funding amount for your project.

You can contact us easily online or by phone. After an initial assessment of your wishes and the structural conditions, we will provide a transparent fixed-price offer, so you have full planning security from the very beginning.

No, modern indoor units from quality manufacturers operate in what is known as whisper mode. They are barely audible in everyday use (often below 20 dB(A)) and are therefore ideal for bedrooms and living rooms.

Yes. If we install a new heat pump for you, we will, upon request, take care of the professional removal and environmentally sound disposal of your old oil or gas heating system.

We design, install and maintain large-scale VRF/multi-split air conditioning systems, ventilation systems and commercial heat pumps. Our customers include office complexes, medical practices, retail stores, hotels and industrial companies.

Yes, the precise and fail-safe air conditioning of IT and server rooms is one of our specialties. We plan redundant systems (N+1 redundancy) so that your IT infrastructure remains protected around the clock, even in extreme outdoor temperatures.

We know that downtime is expensive in commercial businesses. Therefore, we coordinate the installation phases closely with you. Through structured processes, we minimize noise development and disruptions on site, so that your daily business can continue undisturbed.

Yes. For business customers, we offer individual service level agreements (SLAs). These guarantee regular statutory inspections, extended system running times, and, in an emergency, quick response times from our technicians.

Absolutely. We handle legally compliant documentation, conduct the legally required leak tests on your refrigeration and air conditioning systems, and maintain the necessary logbook for your company.

A single-split system consists of one indoor unit and one outdoor unit – ideal for a single room. In a multi-split system, up to five (or more) indoor units can be connected to a single, powerful outdoor unit to cool several rooms independently.

Yes! Modern air conditioners are, technically speaking, air-to-air heat pumps. They can simply reverse the refrigeration cycle. Especially during the transitional months (spring/autumn), heating with air conditioning is extremely fast, efficient, and often cheaper than the primary heating system.

We consistently rely on modern inverter technology from renowned brand manufacturers. These devices continuously adjust their power to the actual demand. Almost all our systems achieve the highest energy efficiency classes (A++ to A+++), which minimizes power consumption.

Yes, modern interior units have multi-stage filter systems. Depending on their features, they not only filter coarse dust but also pollen, allergens, bacteria, and unpleasant odors from the air – a great advantage for allergy sufferers.

Yes, almost all modern systems can be easily integrated into your smart home. You can conveniently control the systems via app on the go, set up schedules, or adjust the room temperature by voice command.

Our focus is on state-of-the-art air-to-water heat pumps and air-to-air heat pumps. These systems use the infinitely available environmental heat from the air to supply your building with highly efficient heating and hot water.

Yes, that's a widespread myth. Modern heat pumps (especially high-temperature heat pumps) achieve excellent efficiencies even when combined with traditional radiators. We assess your building's heating load in advance to design the appropriate system.

Modern heat pumps have been tested for Scandinavian winters and operate reliably even at temperatures as low as -20 °C. Should it get extremely cold, an integrated heating element ensures the heat supply at all times, so you won't have to freeze.

Since the heat pump draws around 75% of the required energy for free from the environment and only needs about 25% electricity to operate, it is extremely environmentally friendly. If you operate the heat pump with green electricity or your own photovoltaic system, you heat almost CO₂-neutrally.

With professional installation and regular, professional maintenance, the lifespan of a quality heat pump is approximately 15 to 20 years – comparable to traditional gas or oil heating systems, but significantly more future-proof.

We operate nationwide! Our headquarters are in Wiefelstede, but we plan, install, and maintain systems for private and business customers throughout Germany.

The process is very simple: After your inquiry by phone, email or via our contact form we exchange all important project data. You will receive a transparent fixed-price offer from us. After your approval, we coordinate the installation date, our technicians install the system ready for operation and you receive detailed instructions.

The installation of a single-split air conditioner usually takes only one working day. A complete heating system replacement with an air-to-water heat pump is usually fully completed and ready for operation within 2 to 4 working days.

To connect the indoor and outdoor units, only a small core drilling through the outer wall (approx. 6-8 cm diameter) is necessary. This bore will then be insulated, sealed, and neatly covered with discreet cable ducts by us.

Of course. Our installation teams work with modern tools, including integrated dust extraction. We will leave your work or living area absolutely clean and take all packaging material and old devices with us directly.

To maintain full efficiency, operational safety and the manufacturer's warranty, we recommend maintenance once a year. For commercial systems (B2B), shorter intervals may be required due to legal regulations (leak tests).

Our technician cleans and disinfects the filter units and heat exchangers, checks the refrigerant pressure and all electrical connections, inspects the condensate drain, and optimizes the system settings for minimal energy consumption.

Please note down or photograph the error code displayed on the control panel or in the app. Then, contact our customer support directly. Since we are familiar with your system, we can usually quickly identify and resolve the error.

Do you have a maintenance contract with us? Then please use the service hotline number specified in it. Our technical emergency service will be with you as quickly as possible to restore the operational readiness of your system.

Our focus is on the support and maintenance of the systems we design and install, as we can guarantee maximum quality for these. However, please feel free to inquire about individual cases – we will check our current capacities.
