Question for our services

Definitely NO!! In SouthAfrica it is illegal for anyone but a qualified electrician to do any domestic wiring or house rewiring. Even if the work has been done to standard it will not pass certification which is bad news especially if you need to sell the property. It makes sense for safety to hire a qualified electrician to carry out all your household wiring. You also risk your personal safety and the safety of your family and friends.
Self cleaning ovens use heat to burn away any spills or splatters inside the oven. The oven will heat at around 480 degrees Celsius incinerating all spills turning them to ash which can be wiped out of the oven once it is cool. The oven will also be fitted with a self locking door mechanism to prevent access to the oven during the cleaning process. Is your self clean not working?

On a normal power circuit, the current flowing to an appliance returns through the neutral wire. If the circuit is compromised, the electricity can leak to earth through a person in contact with the appliance, causing death or serious injury. A safety switch detects the loss of power from the circuit, and cuts the supply of electricity in as little as 30 milliseconds – 0.003 seconds. Importantly, this response time is faster than the critical section of a heartbeat, and therefore significantly reduces the risk of death or serious injury.
A few factors to consider when choosing a ceiling fan are:
  1. Where it is to be installed
  2. The size of the room
  3. Is there need for a fan which includes a light
  4. The room decor
  5. Blade performance needed
  6. The location of your house
  7. Is a remote control fan needed.

General Question for AC

Smart Wiring is an industry wiring standard that once installed allows you to access multiple telephone, Internet, fax, PAY-TV options, as well as security, audio, lighting home automation, and garden irrigation features.
Techair Services recommend that you should have an electrical inspection carried out if:
  • You are purchasing a property that has been occupied
  • The property is more that 10 years old
  • If it is more that 5 years since one has been done
  • If you are concerned about how any of the equipment may have been installed
  • Gas top ups are absolutely essential in the case of unsealed leakage. It is imperative to seal the leaking areas before topping up the gas. Once completed, you will not need to top up gas until the same issue occurs again. A number of factors may lead to gas leakage.
    These may include improper installation, poor quality copper pipe and more. We recommend you to ask an air con professional before attempting any gas top up on your own.
    The basic maintenance that is recommended is the cleaning of the air filter and outer panel of the air conditioner every 2 weeks. This will helps to improve the air conditioning of the room. For a more in-depth servicing, it is recommended to service 3-4 times a year for residential properties, and once a month for commercial. Please seek the assessment of a qualified technician.
