Question 1

How do I get perfect WiFi coverage throughout my entire house?

Accepted Answer

The solution for thick walls and large spaces is not WiFi repeaters, which halve your speed. Instead, we install professional Access Points (e.g., Ubiquiti) hardwired directly to your fiber router. This creates a single, seamless, lightning-fast, and extremely stable network across your entire home.

Question 2

Can you hide ugly network cables inside the walls?

Accepted Answer

Yes! Instead of running cables along your baseboards, our technicians use your home's existing telephone or electrical conduits to pull new, high-performance CAT6 cable. The result is a completely invisible installation that delivers maximum internet speed to your home office, TV, or gaming PC.

Question 3

Can I claim the ROT tax deduction for network and WiFi installations?

Accepted Answer

That is correct. Routing network cables and installing permanently connected IT equipment (like access points) entitles you to a 30% ROT deduction on the total labor cost. This makes upgrading your home's infrastructure very affordable.

Question 4

What is the difference between CAT5, CAT6, and fiber optics?

Accepted Answer

Fiber optic cables deliver internet to your house using light signals and can handle massive speeds. Inside the house, we run copper cables. We always recommend CAT6 cables for new installations, as they support speeds up to 10 Gigabits per second, future-proofing your home for streaming, gaming, and remote work.

Question 5

Can you install network access points outdoors for better garden coverage?

Accepted Answer

Absolutely. We install weather-resistant outdoor access points so you can enjoy fast and stable WiFi on the patio, in the garden, or by the pool. We use exterior-grade cables designed to withstand the harsh Swedish climate and protect the equipment from moisture.

Question 6

What should I do in case of an electrical emergency or power outage?

Accepted Answer

Safety first! If your RCD (jordfelsbrytare) trips repeatedly or you smell burning plastic, do not touch anything. We offer 24/7 emergency electrical services across Greater Stockholm with fast response times. Our certified electricians will secure your electrical system and fix the fault immediately to minimize the risk of fire or property damage.

Question 7

Which electrical installations provide the biggest savings on my energy bill?

Accepted Answer

The fastest ways to lower your energy costs are installing smart home controls (like Plejd) and upgrading to energy-efficient LED lighting. By scheduling your heating and lighting according to spot electricity prices, you can reduce energy waste by up to 20%. We handle all types of electrical work, from smart homes to safe EV charger installations.

Question 8

Can I use the ROT deduction and Green Tech deduction at the same time?

Accepted Answer

Yes! When we install an EV charger, we apply the Green Technology deduction, giving you a 50% discount on both materials and labor directly on the invoice. For other general electrical work in your home (like upgrading a fuse board), we deduct 30% of the labor cost via the ROT deduction. We handle all the paperwork with the Swedish Tax Agency for you.

Question 9

Why is it important to hire a certified electrical company?

Accepted Answer

Faulty wiring is one of the leading causes of house fires. Smista Elinstallation AB is a fully authorized electrical contractor approved by the Swedish National Electrical Safety Board (Elsäkerhetsverket) with over 30 years of combined experience. This guarantees a safe installation, valid warranties, and the official documentation often required by your insurance company.
