Floor Air Conditioner: The Insider’s Guide

Air Conditioner Not Cooling House
Supply and return ducts are the channels through which central air conditioners operate and circulate cool air. The air is transported into your home from the air conditioner, through the supply and registers that are actually openings in the ceilings, floors or walls covered by grills.

This is why it is also referred to as a floor air conditioner.

The best ones can be identified by their high seasonal energy efficiency ratio (SEER) rating. This may result in the cost being a little more, but in the long run, your costs will be reduced, as they are more energy efficient. They utilize less energy and produce the same cooling effect, as others that have a lower SEER. The SEER rating of the most ideal central conditioners is between 18 and 23.

The type of compressor used by this system is an important feature, and is the most expensive component of the air conditioning unit. It is therefore essential that the best central air conditioners have reliable and durable compressors.

The two main compressors that you need to be concerned about are the scroll and reciprocating ones, with reciprocating compressors being the older of the two. There are less moving parts in the scroll compressors than the reciprocating compressor.

They are also more reliable, much quieter and more efficient. Additionally, those with scroll compressors have the capability to resist liquid refrigerants, which are incompressible, resulting in more costs as it can damage your compressor.

The best ones offer a good warranty, which is essential since after installation, there is the possibility that anything can happen to the unit. Having a warranty will eliminate any unnecessary expenditure.

As a result the best floor air conditioner, usually comes with 10 or more years of warranty, which can either be on the compressors or parts of it, or a limited warranty which would apply to the indoor and outdoor coil.

A regular warranty will cover a period of 10 years on the compressor, and 5 years on the other components. Some manufacturers however, have other options such as lifetime warranties, which cover heat exchangers and compressors, while also offering 10 years on the internal parts.

Yet another feature of these air conditioners, is that it has to be equipped with a thermostatic expansion valve (TEV or TXV), which controls the flow of the refrigerant throughout the unit.

Central air conditioners that have lower SEER ratings, are less efficient. They have a fixed orifice, which does not close and remains at the same level, despite the amount of refrigerant that is needed by the unit. The best units are equipped with a TEV or TXV, allowing for the correction of the flow of refrigerant, depending on what is required by the unit.

If you consdier these factors in your search for the most floor airconditoner, then they should not be too difficult to locate.
