Read on to learn a few tips so that you can be assured of a fully functioning and energy-saving air conditioning unit in your home.

  1. Be clear about your air conditioning requirements.

Do you want your whole house to be air conditioned, or do you only need a cooling mechanism for your bedrooms? Do you need both a cooling and heating function, or would you just prefer the former? There are many specifications and details to your future air conditioning system that heavily relies on what your cooling requirements are. Given this, before you start any kind of air conditioning installation in your home, clarify what your home needs and discuss them clearly and in detail with your air conditioning expert.

  1. Check and double check the specifications of your air conditioning unit.

Your air conditioning service team will provide you with a recommendation in terms of the size and capacity of the air conditioning unit you will need, based on your home’s requirements. Have them explain to you why their recommendation is as such, and look through their calculations so you understand what they mean.

We all want an air conditioning system that is efficient and energy-saving. Given this, one of the first things you should do to ensure this even before the air conditioning installation takes place in your home is to make sure you are able to seal off all the air ducts in and around your home. Any gaps that can lead to cool air escaping your home will mean more work for your air conditioning unit, and more energy wasted, that will ultimately leave a dent on your energy bill.

  1. Plan the location of the air conditioner in your home efficiently.

Deciding on where your air conditioning unit will be placed in the home is critical, so that you can optimize the flow of air in your home, but also to minimize noise from the air conditioner.

Instead, read through the feedback and reviews from previous customers, check if they are licensed, certified and has all the proper business permits to operate, and do a proper interview before you award the project to any team in particular.


Reasons Why You Should Hire a Licensed Electrician

You’re looking to start a new DIY project in your home and realize you’ve been meaning to do some electrical repairs on some issues you’ve encountered over the last few weeks. You’re excited to take on the project, but before you get started, consider the possible repercussions if this DIY project goes wrong.

Electrical work in a home requires the right experience and knowledge, and isn’t ideally taken as a DIY project. It would be best to contact your neighbourhood electrician Adelaide to fix the matter for you, but if you’re not convinced, read on to find out more reasons why you should leave electrical repairs to the capable hands of electricians Melbourne.

1. You don’t need to worry about getting approval from inspectors after an electrical project.

Unlike redecorating your living room or installing a new set of shelves in your bedroom where there’s no need to acquire permits or have inspectors visit your home to check your work, electrical repairs and projects will require just that. And while you might be able to squeak by in doing the electrical repairs yourselves, the output might not be up to standard with your inspectors.

Eliminate this worry altogether by hiring an electrician to do the work for you. He is well qualified and experienced to know how to do an electrical job the right way that will pass with flying colors with an inspector.

2. It is safer to hire an electrician to do the electrical repairs for you instead of you pulling a DIY weekend project on your electrical systems.

Unlike DIY projects like repainting your home, working on electrical repairs or electrical installations poses many risks and dangers. Working with electricity requires you to have a good understanding of proper safety guidelines, as well as enough hands-on experience prior. Only a licensed electrician will have these, so it’s better to entrust your home’s electrical repairs to him.

3. There are more fun DIY home projects you can do that are not as risky, less complicated, and ultimately more rewarding.

As mentioned earlier, there are so many DIY projects you can in your home: from repainting the walls of a particular room in your house, building new shelves for your bedroom, redecorating the living room, or adding new plants to the backyard and the garden. A house is never lacking of DIY projects, so why not choose the simpler, more fun projects to do with your family and leave the more complicated and technical aspects like electrical work to the experts?

4. Hiring an electrician might cost you more than doing the electrical repairs yourself, but it can save you more money in the long run.  

So you’re confident enough to take on your home’s electrical repairs yourself, and after committing one full weekend to it, you think you’ve got the job done. That is, until your circuit breaker trips again after a few days and you discover you have the same problem as you did the week before.

You might think that hiring an electrician might be costly compared to your “free” labor, but if you’re not able to fix the electrical problem correctly, it can lead to even greater problems in the future, and quite possibly accidents too. So don’t be stingy when it comes to hiring an electrician – hire the best one you can find and think of it as a worthy long-term investment.

  1. Uncovered Junction Box

Because any junction box can house all splices, where these wires do connect to each other, or with a person might inadvertently damage them leading to a shock. An expert who does the wiring should ensure that these wires are not within reach since they might lead to electric shocks in many cases.

  1. Too Few Outlets

This means that Heavy reliance on power strips and extension cords that may be dangerous for the people who use the specific house. During wiring, the electrician need to use a heavy-duty extension cord of 14-gauge or even thicker. With a thicker wire, it will lower the number of the gauge number as opposed to using an undersized extension cord of 16-gauge or even smaller. Why so?

The Best Air Conditioning Unit For Your Home

In the heat of summer, every homeowner wishes that they had a system of air conditioning. If it is time for you to get your first air con system or you want to replace your old unit; the first step is choosing the right one. Cooling systems come in various designs including outdoor compressors, portable units, and central systems.

This guide from air conditioning Melbourne should help you choose the best one for your home.

air conditioner repair

1. Window Units

The “unitary” air con window units are self-contained and often take a window placement. All its components come packaged in the single unit hence the unitary reference. The system works by expelling heat through the side placed facing outside the window. It then blows cold air inside.

The size of window cooling systems varies. The sizing dictates the amount of cooling the unit can provide. Smaller homes can get efficient cooling throughout with a larger sized window unit.

2. Portable Air Con Systems

The portable air con also falls under the unitary models. It is self-contained and also mobile meaning that it can be moved from room to room. The unit often gets placed on the floor and exhausts heat through a window based hose vent.

Portable units operate considerably noisily compared to other air con systems. They also offer small-scale cooling covering less than 500 square feet. Portable cooling sytems work best to  provide cooling for individual rooms or where window-mounted systems are impractical.

3. Ductless Cooling Systems

The ductless or split cooling systems are synonymously referred to as PTACs ( packaged terminal air conditioners). They are often used in apartments, motels, and hotels. Homes that cannot accommodate forced air cooling systems have also started using these systems.

In the air conditioning maintenance, the air con features two packages placed a distance away from each other. One of the units functions as the condensing unit placed outside the house. The other serves as the evaporative unit placed inside the house. The terminal units are interconnected using a refrigerant tubing running through the wall.

4. Central Cooling Systems

Also referred to as forced air systems, central air cons provide a premium cooling solution for your home. It operates quietly, functions optimally, and offers enhanced cooling comfort when compared to the rest. Central air conditioning units feature two packaged units. They include an evaporative unit placed on your furnace’s plenum and the condensing unit that gets placed outside the house. A refrigerant tubing connects the two units.

The challenge with central systems is selecting one in a correct size that is appropriate for your home. Improper sizing causes performance and humidifying issues.

Choosing a cooling system may prove challenging if you cannot determine your particular cooling needs. Even smaller homes might still end up with the wrong air con unit because several factors affect the decision. The size, build, and square footage of your home determines your home’s cooling load needs. Working with a cooling systems professional can help you figure out what air conditioning system works best for your home and how to do air conditioning repair.

emergency electrical services

You are all excited with your new HDTV as you can finally enjoy your favorite movies and shows in brighter colors and vivid and accurate pictures. The only dampening aspect of getting a new HDTV is it’s installation as it has to be properly installed, preferably by electrical specialist for maximum safety and enjoyment.

One of the appealing aspects of flat panel TVs is its wall installation with concealed wiring. All the electrical and television signal wires have to pass through the walls and into the concealed junction boxes behind the mounting bracket. It’s a professional technician who ensures the TV outlet installation is properly fit against the wall, with minimal visible wiring.

The right position

While home decor magazines portray a sleek, flat panel TV mounted over a fireplace it’s not the best location for your TV. There is the risk of your TV catching fire if you have a wood-burning fireplace.

Besides, the fire generates heat and smoke which is not good for your TV. However things are different with a gas fireplace as they usually have vents for heat dispersal so there is no risk of the heat reaching your TV.


 local electrician sydney

You and your electrician brisbane will have to decide on the best potion for your HDTV. It should be preferably mounted at eye level when you are seated as you strain your neck if it’s mounted too high.

Remember that plasma flat panels give a more consistent picture quality when viewed from the side. However the blacks in liquid crystal screens tend to turn grey, and colors shift to different tones if viewed from the side.

That’s why your electrician will suggest mounting your television as close to your normal line of sight while seated, and not at an angle as this is when the picture is clearest. If you have to mount your TV a bit higher, your electrician may suggest using a tilting wall mount to help angle the TV downwards.


Once the spot is decided, your electrician will mark the bracket spot by aligning two vertical studs in the wall. They will then cut an outlet-sized hole at the outlet’s height towards the base of the wall.

This is usually a foot from the floor and it is through this hole that signals cables pass from the equipment back to the TV’s back. Your technician will then use nose plates to terminate and conceal both junction boxes and let the cables pop out unobstructed.

Following the code

According to code, you need to have a metal junction box installed for the AC wire. Your electrical repair technician will either run the AC wire from the service panel in your home’s lower level to the new outlet’s location, or install a kit that jumps a nearby outlet to service the new outlet behind your television.

 electrical repairs

These kits comprise of the necessary new outlets and the Romex and extension cords needed for installation. It however is against the code to pass an extension cord or the TV”s power cord directly through the wall as the code accepts only shielded or unshielded Romex for in-wall use.

As so much goes into the proper TV outlet installation of your new HDTV, it’s imperative that you hire professional technicians to complete the job instead of you attempting to do it on your own.

Oven Troubleshooting And Repairs

oven repairing

Before you attempt to repair a malfunctional electric oven, it is imperative to take into consideration all the necessary safety precautions. Unlike the gas ovens, electric powered oven usually involves an enormous amount of energy flowing through the entire system, approximately 220 volts. So for you to create a safe and a conducive working environment you should just ensure that you either disconnect or shut off the power to your oven.

Even though ovens are usually extremely durable, there are a few problems that would occasionally arise with their continued use. Unfortunately, most of these problems are often complex, and you may not be able to troubleshoot them on your own. Issues such as no power, your oven not turning on as well as other problems can only be solved with the help of a qualified electrician or a support engineer.

In this post, we will examine some of the most common oven problems and a brief and practical ways on how you can solve them personally.

 east brisbane electrician

 1. Power issues

The first move you should make when examining if your oven has a faulty power supply is to inspect the condition of the fuses on your device. Fuses that are faulty can potentially render any component in your house ineffective and are one of the primary reasons for power related problems around your home. If no sound or light is coming when your cooker is on, then you should try to heat up one of the hobs on your oven. If you realise that the hob glows and you can feel some warmth, then definitely your power supply is functional, and this implies that the issues are to do with the internal components of your machine.

 2. The bake element

If the heating element of your device works, then probably you have a bake element or wiring issue to deal with. On most models, the bake element is usually located on the bottom of the oven. It is black in colour and of the same size as a pencil. The bake element is typically connected to the oven by two screws. Eliminate these screws and pull out the bake element. After this, attach a 240V circuit to the terminal of the element. Connect your oven to a power supply and turn it on to see it bakes. If the light is on, just know that the bake element has burned out and the only solution is to look for a replacement. In some instances, you’ll find that the food will partially cook even when your bake element is faulty, and this is because the broil element is heating your food. If the light doesn’t come on, then the whole problem lies in your wiring.

 3. Wiring problems

The wiring of your oven is located on the back panel of your device. Check inside the back panel and see if there are any burnt terminals or wires. If any, remove it before replacing it with a nickel-plate terminal of high temperature.

 4. The door, as well as the control knobs, is getting too hot

This particular problem is common in appliances that do not have a cooling fan. A cooling fan blows cold air out from the top of the device thereby cooling the control knobs and doors. So in cases where there are no cooling fans, individual devices may feel sweltering to touch.

 5. Thermostat

If your oven functions and even cooks at really low or high temperatures, check your thermostat’s sensing bulb. If you didn’t know, this particular bulb could sometimes come loose, ending up either on the floor of the oven or the heating element. On most occasions, the thermostat will require recalibration, a task that only needs the attention of a qualified and an experienced technician.

These are some of the most common problems which typically occur on your electric oven. Of course, there are others such as issues with the broil element, intermittent burners, your oven burning food or even the oven door failing to close properly.However, if even after conducting all these procedures and your oven still misbehaves, in such a case you will have to contact an experienced technician for relevant assistance.

What You Should Know About Electrical Surge Protectors

electrical power surges

Also known as voltage surges, electrical power surges are quick and temporary spikes in voltage within an electrical circuit. The occurrence of these surges is unavoidable and happens when something boosts the circuit’s electrical charge at some point. This particular boost increases the current that flows into or within your home’s electrical wiring thus affecting the appliances, lighting as well as other electrical equipment in your home. Power surges can be as a result of many different factors including lightning, faulty electrical wiring or even sudden turning on or off of a high power electrical appliances such as a large electric motor or your HVAC.

It is estimated that more than half of household electrical power surges are internal. Such surges occur a couple of times, especially when your home devices with motors either start up or shut off, diverting energy to and from other devices. In this regard, air conditioners and perhaps refrigerators are the biggest casualties, even though other smaller devices such as hair dryers can equally cause problems. On the other hand, external power surges, which commonly stem from outside your property, are usually caused by a tree limb touching a power line, a small animal getting trapped into a transformer or lighting striking a particular utility equipment.

electrical power surge protector

Why should you worry about electrical power surges?

Your home contains lots of items that are susceptible to power surges. As such, anything that has a microprocessor is especially vulnerable since they are incredibly sensitive that even a small power fluctuation of a 10-volt can potentially disrupt its normal functioning. Microprocessors are found in some household items such as cordless phones, refrigerators, washing machines, computers, as well as TVs. Large power surges caused by lightning strikes might cause massive damage such as frying circuits and the melting of plastic parts. Simply put, power surges can lead to cases of fire.

How can you protect your home appliances from incidences of power surges?

First and foremost, it is crucial to note that even the typical surge protector is not adequate to protect your appliances and electronics from a lightning strike. This means that the best thing you can always do is to unplug all your electrical devices during raging electrical storms. However, if you are residing in an area prone to faulty wiring, you should invest in a surge protector.

Point-of-use surge machines for surge protection, integrated with excellent grounding system can potentially protect your electrical appliances and electronics from even the most damaging power surges. It is worth mentioning that surge protection devices does not either arrest or suppress a surge, but typically diverts the surge successfully to the ground

Possible approaches to surge protection.

  • Point-of-use devices can provide protection to your appliances in your house, but for a more practical and effective approach to an adequate protection is to integrate point-of-use protection devices with another device such as a service entrance a power panel surge protector. By using two-tier surge protection, you’ll probably protect your entire home from the dangers of even some of the most powerful electrical surges.
  • Surge entrance protection devices typically mount on your primary power panel or even at the base of your electrical meter. This particular approach provides protection for the whole of your electrical system, including appliances such as light switches, outlets, motors, etc.


What should you look for when choosing the most efficient surge protector?

It is imperative to note there are numerous and different surge protection devices on the market, and this implies that the prospect of choosing the best that fits the needs of your home can be an awful experience. However, the general rule is always that the bigger the device, the better. In this regard, large refers to the Joule ratings, and this is the capacity of the surge protector to absorb electrical spikes.

For maximum protection, you should look for a device that lists at least six hundred joules or higher. If you didn’t know, anything lower than that might not be sufficient especially if your home usually experiences regular power spikes or you are planning to plug several devices into the strip. The most effective type of surge protection should be a whole house surge protector. It refers to a single device which connects to your primary electrical panel, thus protecting your entire home. These devices reduce the surge that occurs when lightning strikes your home or even if spikes happen in your main electrical line.

As always, you should contact your local electrician who has adequate knowledge regarding the installation of electrical surges.
