Question 1

What does energy optimization in a home mean?

Accepted Answer

Energy optimization is about using electricity smarter without compromising on comfort. It often involves installing smart controls for heating and lighting, replacing inefficient components (like older thermostats or lighting), and utilizing spot prices so that energy-demanding equipment runs when electricity is cheapest.

Question 2

How much money can I save by installing a smart home system?

Accepted Answer

Depending on your current habits and heating system, a household can save between 10-30% on heating and lighting costs. Heating accounts for the absolute largest part of the electricity bill in a house. Lowering the heat automatically when you are not home or at night has a significant impact.

Question 3

Is it profitable to switch to smart lighting (LED) in the whole house?

Accepted Answer

Yes. Lighting can account for up to 20% of household electricity. By combining energy-efficient LED bulbs with smart controls (e.g., Plejd or Wiser) that automatically dim, use motion sensors, and turn off everything with a push of a button at the door, costs are dramatically reduced while convenience increases.

Question 4

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 5

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 6

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 7

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.
