Central air conditioning
« on: March 08, 2015, 12:15:02 PM »
at some point in the future we hope to build our own house and we would love to have central air installed vs the ubiquitous window air conditioners.  But, not sure if it will be cost prohibitive to have this installed with the construction.  Does anybody have any experience with central air?

That was also our intention before our house build started, but our plans for central air conditioning just fell on deft ears. So, we just had the split type A/C installed in our home. Anyway, good look to you to find a good reputable central air conditioning specialist.

Ive only seen the split type here (other than window units)  I can only say if you go for one make sure its the inverter type, from everything Ive seen they are much cheaper to run...
The only thing worse than wanting to do it is not doing it

Was thinking about central air when we built our house here in the province but it did not worked out. Would be too costly to operate because of the way the house construction is done here. Walls had to be insulated, insulation in the ceiling and air tight windows. Here the walls are built with hollow concrete blocks then rendered to a smooth finish. No insulation. Most roof do not even have insulation or the thin insulation which is installed just under the roof panels. Windows are no airtight.
So a lot of wasted cool air would be escaping out. We end up using the inverter type split air conditioner. For installation they cut a small 1" or 2" hole in the wall. The driver unit is mounted outside with the air dispenser inside. Works very well and not noisy like the window type air conditioner.
Never look down on anyone and always extend a helping hand. Tomorrow the role may be reverse.

When inverters first came out, I guess they were the only way to go.  Not so anymore.  I got all Carrier Optimas a couple of months ago which are non-inverters and they are very energy efficient.  How do I know if I just got them?  Well, I saw a couple of others in action for over a year.  I do have an inverter refrigerator though.
Whatever floats your boat.

Do you know enough about them to compare electric bills?  Had a nice non-inverter that Yolanda took out and replaced with a window unit due to purchase costs to replace it.

One of the things I do to keep me busy is one, I will take the reading off my electric meter most every morning and enter it in a spreadsheet.  I set my spreadsheet up to perform calculations which tells me various information.  Things such as daily usage, daily average usage, anticipated usage and cost of the next electric bill, etc.  One of the units which I kept track of for a year was the one my wife bought for her office.  Between that one and another, along with the research I have done on them, I have enough confidence in them that they are the way for me to go.  There haven't been any days yet where I needed to run the ones downstairs but as we know, it gets warmer near the end of the day upstairs.  I have enough info off the one we have in the bedroom to know what it does.

By the way, when the hot weather rolls in, a lot of people agonize for most of the month on what they will find when they open their electric bill.  No such surprise for me as I don't have that problem.  As the month goes on, my calcualation becomes more accurate and I usually know down to easily less than a hundred pesos (since it is based on a kwh cost from the previous month and depending on what time of the day Mercalco read it) on what to expect.  If I am going to have a high electric bill, I know well in advance and sleep easy as I don't like to spend money if I don't have to.

As I said, it helps to just give me something to do rather than to go find a job.

Well done Bud.
Everyone should be taking an active interest in their power usage.
Entering the data into a spreadsheet is a great way of capturing that data and analysing it.

Once you have the information, you are able to budget your upcoming expenses, and also identify faulty appliances, or parasitic connections.

Same goes with the gas milage in your car. Take note of the amount used and the distance travelled.
Makes it easy to spot a problem with the car.

Anything really that can be measured and analysed.
For those on tight / limited budgets, the more control that you have over your expenses, the more comfortable you will be.

Bud is onto a winner with this  :)

Thanks all for the extremely informative responses.... Looks like central air just aint gonna happen.  I wonder how costly it will be for some type of semi normal insulation.  I will ask as we start to move forward and share all my experiences.  Thanks again

You can build the house of your dreams anyway you like. You just need the patience, know how and most important, cash! Yup, it's all about money!

I have the Patience its the know how and cash that are in short supply.  I will ask about the cost, but my initial fear is it is going to be way out of my price range.

Thanks LL.  I have no need for a vehicle currently but yeah, I use to keep track of fuel for my trucks.  Anytime I pulled in to get some petro I would always top it off completely.  Once the break-in period was over I would not get much of a variance in between fill-ups with just the normal up and down slightly between oil changes along with the difference depending if I had been cross country or around town.  Of course, the last time I had a vehicle in the shop for something other than a tune-up. oil change or tires and rotation was I think back in '77 or '78.  I just started with tracking the electric more closely since I have more time retired and got here.

I would give a big thumbs up to split inverter aircon units. When we had our house built we had these installed in all rooms, quite expensive but well worth it. And they seem quite cheap to run.

As our house was a standard one in a sub division we had to get the wiring system upgraded to cope.

We just have the bedroom setup with AC, and upgraded the wiring as well to handle it.  Went from a two fuse box to a full breaker panel.

We just have 2 split units but we visited a fellows house in Liloan Cebu one year and he had central air, 220 and 110 circuits and used a US thermostat, so he could keep the temp at what he was used to, it was a neat setup but he is no longer around for me to ask questions to about how he did it, just saying apparently it can be done.
