How To Build Your Own Air Conditioner Using Just Plastic Bottles

Air conditioning that uses zero electricity? Sounds like it might be an interesting concept, but isn’t there always a catch? Here’s an innovative idea, especially when you consider that you would never need air duct cleaning, and you’d never need to worry about changing air filters or doing any maintenance either.

But would you really want something like this stuck in your window? It certainly wouldn’t do much for your curb appeal, and security would definitely be another factor that you’d need to consider.

Otherwise, its an amazing concept if it really works, and I’d be quite interested to see if the inventor has come up with anything else related to the HVAC field or anything that can save in energy costs.

Plastic bottles are usually destined for the recycle bin. But there are some very interesting upcycling things you can do with plastic bottles. Such as creating a zero electricity air conditioning unit!

Bangledeshi inventor Ashis Paul came up with the plastic bottle air conditioner, and it is already being used in over 25,000 homes in his country! Ad agency Grey Dhaka and Grameen Intel Social Business have contributed to these incredible efforts.

Really all you need to make your own Eco-Cooler is a board and a few plastic bottles.

First you cut the bottles in half. Then mount them into a grid through holes which are also bottleneck size. Now place the grid right over the window. The narrower top end should be facing inwards to the house.

Wind will blow through the bottles, and the result is cool air being funneled in.

It can reduce temps to up to 41F (or 5C). Not bad at all considering it doesnt cost anything to actually make!

The hope is that this project reaches as many people as possible. Hence the project will be put online for free.

85mmx dirty condensing units

What about the exterior condenser?

Your outdoor air conditioning condenser unit is an integral part of your HVAC system. It contains the compressor, a fan and a coil.

The smooth and dependable operation of your air conditioning system overall, depends in large part on how clean your condensing unit is.

When your air conditioning is on, the compressor runs, as well as the condensor fan. This moves the required amount of air across that coil.

Grass, weeds and shrubs can severely impede the air flow across the coil, to the point where your system can freeze up. And as with anything, if you want it to work efficiently, it must be clean.

Your outside air conditioning condenser needs attention just like the interior air duct system does. The maintenance required to keep this part of the system clean is very minimal considering the amount of work that it is required to do during Toronto’s long, hot summers.

The compressor and fan will very rarely require any maintenance from a homeowner. Those parts of the system are best left to a trained professional.

The outside coil, however, will need to be cleaned from time to time though, and this is the part that anyone can do themselves if they want to take the time to do it.

It is best to check the cleanliness of the coil at the start of the cooling season, or whenever you first turn on your air conditioning. The coil should also be visually inspected at a minimum of once per month during the cooling season as well, and especially so if you notice that your outside unit is starting to sound louder than it normally does when it is running.

If you have determined that your unit needs to be cleaned, this can be easily accomplished with your garden hose and a stiff brush.

First, make sure the power to the unit is off. Then use a strong spray from your garden hose and thoroughly wash the coil with water only. You can use the brush if needed, but be sure to brush any part of the coil in the same direction as the fins. You do not, under any circumstances, want to bend the fins at all, as this will restrict the air flow going across the coil.

If you forgot to turn the power off first and the unit comes on while you are cleaning it, you will get wet for sure!

Once you have the coil looking clean, that is it. It is not recommended that the homeowner remove the top part (condensing fan) in any case. If your unit requires further service at this point it is best to call in a professional.

Keeping your condensing coil clean will save you money because the system will not have to work nearly as hard to do its job.

Some quick tips for starting up your air conditioning at the beginning of the season include:

  • If you have a cover on your exterior unit, remove it first.
  • Visually inspect the condition of the outside coil and clean as necessary.
  • Check or replace your furnace air filter.
  • Check the drain tube that comes from the inside coil (normally above your furnace) for proper drainage.
  • Close the damper in the bypass tube of your furnace humidifier.

Once the system has been on for about half an hour, go back and check that water is draining out of the drain tube properly.

For best operation of the system in every home, you will need to adjust the air vents at the start of each heating and cooling season.

To set up your air vents for cooling, close the basement vents completely or block them off with vent magnets. On the main floor you want the vents, including dampers, to be half-way open. This setup will help to push more cool air upstairs, where you will need it most.

On the top floor, all vents should be fully open, unless you have an excess amount of air going to very small rooms such as washrooms or closets. And always make sure that return air vents are free and clear of obstacles or obstructions.

Making these small adjustments to your system as needed can have a huge impact on the proper efficiency of your HVAC system, and will do alot to add to your family’s overall comfort level inside your home.

Also remember, on hot days you should always block out direct sunlight, as this will add alot more load to your air conditioner.

If you ever have any questions about your furnace, air conditioner or duct system, no matter how small, feel free to call us and ask. We would be very glad to help!

Dirty air filters

Not So Cool?

Considering the extremely hot summer we are having, you are most likely operating your air conditioning system more than not. But why is it not cool in the house?

If you are experiencing a lack of cooling, chances are that your air filter is very dirty, or possibly plugged, therefore inhibiting proper air flow.

Your furnace and air conditioning systems both require clean air filters to run properly. Dirty air filters is the number one cause for “no heat” and “no cooling” service calls.

Before you call for service, check the condition of your air filter and clean or replace it as needed.

Also be sure to check the position of any volume dampers in your air duct system, and check to make sure that the damper in your humidifier bypass tube is closed for the summer.

If your air conditioner still does not seem to be cooling, check the outside condenser unit. When the air conditioning turns on, the compressor and the fan outside should come on immediately, as should your furnace fan.

You can hear the compressor, and you should see the outside fan when it is running. If either of these two items do not appear to be working when your air conditioning is on, then you should first confirm that the breaker or switch is “on”. Note too, that both your furnace switch and the air conditioning breaker or disconnect box should both be switched to “on” . If these steps fail to rectify the situation then you should call for service.

It is our hope that these quick central air conditioning tips will help prevent at least some people from prematurely calling for service unless it is 100% required.

Enjoy your summer and please stay cool!

Why Is It Important That the Air Stream Side of the Furnace is Cleaned

At City Duct Cleaning we always clean the air stream side of the furnace with each and every duct cleaning. We will clean out the filters, fan, fan compartments, heat exchangers, the air side of the plenums and the coils. This service is included in our base cost, as we find it one of the most important jobs to complete in a home.Anyone can just clean the duct system in your home. Great, the inside of the ducts may be cleaned, but once your system becomes active again, your ducts are just as dirty when you started. The key is to clean the above components as part of the job.During the procedure, we block off all the vents in your home, and our powerful truck-mounted vacuum puts your duct system under negative air pressure. We then supply 250 psi of air pressure to the actual vents as well as inside the main ducts. There is no where for the dust to escape.

If the air stream components are not cleaned as well, then they could possibly re-infect your heating and cooling system as soon as you start using your heating or cooling again. There should never be an extra charge to have this section completed.

There are, however, some exceptions to this rule such as when a coil is extremely plugged. This means the coil has collected so much dirt that it will no longer allow air to pass through it. Plugged coils require a lot of time to clean properly and if this is the case then there will always be an extra charge. Otherwise, a normal cleaning as part of our service always completes the job.

Duct Cleaning Safety At Work: Part 1

Just for fun, let’s take a look at these photos about Safety At Work…

This series of photos have absolutely nothing to do with us or the way we do our work. In fact, we have an excellent work safety record which is due to several factors such as staff training and a company Health and Safety Policy. Safety to everyone concerned always comes first.

Its still fun to laugh about how some other trades people do their work. You may notice that there is no “duct cleaning technician” photo in here.
