Question about Heating & Cooling

Central Air Conditioner (house trailer)

I have a central a/c in my trailor. All summer long it would only come on when it wanted to. It may come on but after it shuts off it may not come back on for a week or two. I tried changing the thermostat but it kept doing the same thing. Could the problem be some type of relay switch in the a/c unit itself? I appreciate any help or suggestions someone can give me.
(I don't know the a/c brand name / its works by itself and not off of a heater thermostat)
Thanks so much :)

Tip

Central Air Conditioning or Window Air Conditioner


Many people look into installing air conditioning in their home every year. There are many options to consider when it comes time to make that decision. To help make that decision more clear, I will explore some of the positives and negatives of the two major options. Ductless Split A/C type units lately are also becoming more of a popular option. I will do another “Tips and Tricks” on that option. To include that in this one would just be more confusing. So for now we will just look at window air conditioners and central air conditioning.

Central air conditioning is usually the best way to go if you already have a central hot air heating system already installed in your house or building. The advantage that you have is that you already have the air handler or blower part already installed. The ductwork for the distribution of the air is also all ready in place. The ductwork may need some modification to make it work well for air conditioning, but the major part of it should be adequate. To use the existing furnace and ductwork an A/C coil will need to be installed at the furnace. An outdoor condenser unit will be installed outside and copper tubing will be used to connect the coil to the outdoor unit. Some electrical wiring will need to be done to power the outdoor unit. Low voltage wiring will also be needed to hookup the thermostat, the furnace, and the outdoor unit together so that they can talk to each other. Basically the thermostat will just tell the furnace to run the blower on high speed and the outdoor condenser to start up.
If there is no central hot air heating, then the installation of central air conditioning can be much more difficult. Many homes that do not have hot air heat also do not have the room to install ductwork. This would eliminate this possibility. If you are in this category you should get a professional to look at your situation to see if central air conditioning can be done. If it is the room available is to enough to do a good job and get large enough ductwork installed, then do not force the issue and go another option. Ductless split type air conditioning may be your best option.

A window air conditioner in my opinion is a last resort for air conditioning your house or building. There are many down sides to window air conditioning units. There are two good things that window air conditioners have going for them. They are very inexpensive when it comes to cost per BTU of cooling. They also install very quickly and easily. That is where the good part of them ends.

Window air conditioners are security risks. If a thief wants to get into your house, the thin sheet metal box that holds the unit in the window can easily be pulled apart to get in through the window. I have seen many units that are not even screwed fast. If the window air conditioner is just there, balancing in the window frame, it becomes very inviting for a unexpected guest. The window air conditioner is also very inefficient. These units use more power per BTU of cooling than any other type of air conditioner. If you are a light sleeper, than chances are you will not want one of these window shakers. Window air conditioners are one of the loudest forms of air conditioning.

The fan for these units is very loud when running. Then add the noise of the compressor and you have enough decibels to keep many people wide awake all night long. If you choose to use a window air conditioner, than you should also look for a place that it can be secured and placed in a room that you will not be sleeping in.


As you can tell by now, I am not a big fan of window air conditioners. They do have a place for some people. However, you do need to be aware of the problems that you may encounter with them. The low initial cost can be offset by the fact that they typically do not last as long as a central air conditioner.

Central air conditioning will last much longer, be quieter during operation, be more efficient, be more secure, but the initial cost will be higher. How much depends on each situation. When considering your options for air conditioning installation you need to get prices for everything and then decide what type of unit will work the best for you.

How large a space are you hoping to cool? One room? One LARGE room? One SMALL room? One floor of a two-story house? A whole four-story house?

What's your climate like where you live? Very hot, dry, year-round? Cool most of the year but two weeks of hot during the summer? Just a little too warm in summer? Blazing hot all summer, including nighttime?

How's the insulation in the building you want to cool? Is it a plain steel building with no insulation? Is it a trailer? Is it a frame house with 4" walls and R13 fiberglass insulation? An old frame house with no insulation? An adobe building? A timberframe house with 8" of polyisocyanurate foam insulation?

All these are important to know when you select an air conditioner.

For most of the USA, assuming a frame house with 4" of fiberglass insulation, a 10,000BTU air conditioner will cool one large room or two small rooms pretty well, or a 5,000BTU AC will do one medium-sized room. Different places, and different house designs, and different types & amounts of insulation, will all have a profound effect on how much AC you need/want.

The power on my N120E - DeLonghi 12,000 BTU Portable Air turns itself off


The DeLonghi Pinguino Air Conditioner is such a smart choice for people in need of a little extra cooling in their homes! My better half purchased our a couple of years ago when he realized his office was getting much warmer in the Summer than the rest of the house. Being hot natured, he thought a portable air conditioner would be a smart choice. We've loved it! It's on wheels, so you can move it from room to room quite easily (even my 10-year-old has been known to move it.) It's outside vents attach to an adjucstable plate that fits right in any size window in seconds. Just select what temp you want it and... done! Super easy.Right now we're currently using it instead of our central unit while the temps aren't too very high.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

Central air conditioner will not turn on at all.


I understand this to be a heat pump. Check your thermostat settings, and the filters. And make sure a breaker isn't tripped.

Amps needed to run a central air unit


Central air requires a 2 pole 30 amp breaker or fuse. You may be able to get by without it but 200 amp service is recommended.
