aircon smell

So, if your indoor space seems to develop nasty smell every time you run your AC, then this is definitely not something you should ignore because it adversely affects your indoor air quality too. So, it is crucial to get the issue identified and see what can be done to fix it at the quickest so you can enjoy the fresh, cool and quality indoor air in your living space.

While there can be several causes that make your air conditioner to blow foul smelling air, below is a list of some main causes and how they can be resolved.

Too big air conditioner for your space

Your air conditioner has two primary functions: to cool and to dehumidify. It cools your homes and removes heat and moisture from your indoor air. If you have a too big air conditioner for your room, it will cool your indoor too soon that dehumidification won’t take place adequately. On high humidity days, mildew and mould will develop and grow on some of your AC’s components that will blow out foul smelling. So, it is crucial to have the right sized AC system for your indoor space.

Clogged condensate drain

When you have a clogged condensate drain with dirt and grime particles, water will be blocked in the drain pan, that may become a breeding ground for fungus, mildew, mould, etc., which will produce a nasty foul smell. So, it is important to make sure your condensate drain is out of dust, dirt and debris, which you can achieve through regular system maintenance.

Dirty cooling or evaporator coil

Microorganisms or bacteria will develop and grow if your cooling coil is dirty. And as your AC blows, foul-smelling will be picked from the coils and distributed to your indoor. So, check your cooling or evaporator coil for dirt and make sure it is clean. A visual check-up may require removing some panels from the blower or furnace, so taking a professional’s help can be the best solution to resolve this issue.

Air filtration system problems

If you have dirty filter issues, your AC’s air filtration system will not be able to remove contaminants from your home’s air, which will give off foul smell inside your home. It is important to note that your AC’s filter should be changed for every 1 to 3 months, depending on the use, to ensure your filter works optimally as it should.

If your air conditioner blows foul smelling air, hiring a professional air conditioning contractor is the best solutions and get solved the issues in the proper way. Contact the qualified air conditioner repair and maintenance services in Sydney to access your system and find the underlying causes and help solve the issues efficiently and quickly.

All You Need to Know About Ducted Heating, Its Repairs and Costs

What is ducted heating?

This heating system is highly flexible. It allows you to warm up rooms individually and all at the same time. It is composed of a central unit that is connected to other ducts. The warmth is spread to these branched-out pipes from the main furnace through various parts of your home.

Common issues and common solutions

Check the pipes and unclog them if necessary

This is a very common issue that leads to malfunctions of your heating. When the ducts are full of dirt, the fan will be overworked. Furthermore, this problem may lead to ignition and pilot control issues.

The solution is to change the filters and clean the ducts once a month. The best way to go around it is to seek instruction from a heating repair professional or to simply hire him.

Regularly check your thermostat!

Sometimes your thermostat will run out of battery or won`t be well adjusted. You will usually be able to solve such issues by yourself.

ducted heating cost

Battery-replacement should not be complicated. It will widely depend on the model of the heating system you have. Your thermostat also might not be in the heat-mode, i.e. it should be set somewhat higher than the room temperature.

Close-off all the possibilities for draught

Pilot-light issues are usually related to drought. This is usually a consequence of open windows and doors that let sudden gushes into the room. Please make sure you close them all so you avoid bigger problems and incurring more bills on a professional repair-man.

Inspect the power supply

If your heating system suddenly stops working, don`t get heated up. Sometimes, it is simply due to the electrical cord not being appropriately plugged in or safety-switch being turned off because of a fuse blow.

Maintenance cost of the ducted heating system

The fee for the ducting-installation, in general, greatly depends on whether you have a pre-existing duct work. This goes for every country. In the USA, for example, the average price is $6.000 to $8.000.

This, however, can rise up to the $15.000 if you need any sort of renovation such as wall opening. This system is frequently compared to reverse cycle air-conditioner.

With the latter, you have to consider that your electrical bill will be higher. On the other hand, you can also use it in summer to cool down. All in all, it is all up to your needs and preferences.

Conclusion

In a nutshell, the ducted heating system has a lot of conveniences. It is also energy-efficient. You can manipulate which rooms you want to use it in. No matter how cold it is, the system will maintain the work quality. This all means that your bills will not get higher as well.

Cool Your Home With The Highly Energy Efficient, Two-Stage Air Conditioner

It is imperative that you should always take great care of your cooling and heating unit. By taking care of your HVAC device, you’ll not only be enhancing its efficiency but, you’ll also be cutting down your energy costs significantly. What’s more, it would possibly make your cooling machine last for an extended period.

There are a few things that you can do to help maintain your air conditioning. This may involve checking your air filters, cleaning your equipment regularly, keeping the area around the unit clear and perhaps scheduling a routine air conditioning technician inspection.

Air conditioners are available in a wide variety of options, ranging from complex whole-house zoned units, ductless to forced-air and window units. Some homeowners are quite familiar with nearly all types of air conditioners named above. However, there is one particular type that most of you haven’t ever heard of. This is the two-stage cooling and heating system. So today in this particular post, we want to discuss in excruciating details, all you need to know regarding about this new fantastic type of air conditioner.

So what is a two-stage air conditioner?

If you are an individual seeking to replace his or her old or damaged cooling and heating unit, then you should seriously consider investing in a two-stage HVAC unit. Typically, this unique heating and cooling unit have a superb compressor, and this is perhaps what sets it apart from the rest. It is imperative to mention that the conventional air conditioners usually run at a single speed only and that is at high speed. This implies that it may be quite difficult to regulate how much you would want to cool your house. Simply put, standard AC usually cycles on at full blast, regardless of whether you need that much cold air or not. As you would guess, this equates to a substantial amount of wasted electricity.

However, a two-stage air conditioning is highly versatile and runs at two distinct speeds. You can operate it at both high and low speeds. What’s more, this incredibly advanced cooling and heating system typically utilises a variable speed air handler to regulate the amount of air that comes into your home thus offering your ideal comfort as well as unmatched energy efficiency.

It is imperative to note that this particular air conditioner usually operates at a relatively lower speed nearly ninety per cent of the time. One good thing is that even at this speed, a two-stage air conditioner still meets the cooling and heating requirements of your home. Besides, it would still be able to keep your house cool while running at fairly lower speed during the hot season.

With the functionality to ramp up its cooling capacity, a two-stage cooling and heating unit adjusts accordingly to your home’s requirements when the temperatures soar. To be more precise, when the temperature rises and humidity increases, a two-stage compressor immediately responds and adjusts its output to a relatively higher speed to help the device keep up with your cooling demand.

So what are some of the benefits of installing a two-stage air conditioner?

There are lots of potential benefits that you’ll enjoy when you invest in a high-quality two-stage cooling and heating system.

Increased durability: A compressor that usually shuts off or on more regularly is subject to greater tear and wear, a phenomenon that eventually reduces its lifecycle. However, with reduced instances of on/off cycling, the two-stage AC units are likely to serve you for longer periods.

Increased efficiency: This is arguably the most important factor that should make you consider this type of cooling and heating device. The air conditioner is extremely energy efficient, and this is primarily because the unit comes equipped with a variable speed air handler that simultaneously regulates the amount of air that moves into your house. This functionality not only provides you with the ultimate experience regarding comfort but equally saves you a significant amount of energy.

Unmatched humidity regulation: When your air conditioner operates continuously, it can potentially dehumidify the air much better. Most of the conventional air conditioning systems feature a compressor that may not be able to draw water vapour from the air inside your house appropriately. However, bearing in mind that a two-stage compressor functions continuously, they usually give the coils adequate time to remove the water vapour from your home.

Though a two-stage air conditioner is extremely versatile and comes with other lots of benefits as well, you are still encouraged to ensure that you conduct regular air conditioner service and annual inspection. All experts agree that this is when you can help extend the overall lifecycle of your unit.
