Central Air Conditioning

Central air conditioning is found in nearly three out of four new homes, and an increasing number of people are replacing their old evaporative coolers to central air as well. Today's modern air conditioning systems are found to be quieter, cleaner, easier to maintain and have much better operating cost efficiencies than those found even 10 years ago. Let's take a look at what's new.

Two factors matter most when purchasing an air conditioner, S.E.E.R. rating and cooling capacity.

S.E.E.R. Ratings
S.E.E.R. stands for Seasonal Energy Efficiency Rating. The higher the S.E.E.R. rating, the lower your operating costs. The S.E.E.R. rating is a formula derived from the cooling capacity, amperage use and voltage supplied to the air conditioner. You'll soon become familiar with ratings with numbers of 10 through 18. The government has set the lowest allowed efficiency limit on air conditioners to 10 S.E.E.R. Many of the older air conditioners that had much higher operating costs may have had S.E.E.R. ratings of 8 or even as low as 6 S.E.E.R.

Even though the higher S.E.E.R. air conditioners save on operating costs, they also cost more to purchase. Ask one of our sales representatives at Manwill Plumbing and Heating to calculate the payback of purchasing a high-efficient air conditioner. You may be surprised at how low your monthly operating costs actually can be.

Cooling Capacities
Cooling capacities are rated in tons of cooling. Nope! the air conditioner doesn't weigh that much! One ton of cooling is equivalent to removing 12,000 BTU's of heat from your house in one hour. It may sound confusing but this is why sales representatives from Manwill Plumbing and Heating L.C. come to your house and make an "on site" inspection. To ensure the proper size, we take in consideration the direction your house faces, insulation values in the walls and attic, type of windows, color of your house, duct size and furnace blower size. All of these factors help determine what size air conditioner you really need. You'll find ton capacities from 1.5 tons up to 5 tons for residential use. We want to determine the proper size needed to adequately cool your house when the temperature really gets hot.

A little more about air conditioning.

Refrigerants:
There are two types of refrigerants most widely used in our industry. The first is R-22. R-22 has been the refrigerant of choice by many manufactures for the past 30 years. Recently a new refrigerant named R-410, sometimes called "Puron," has hit the market. This environmentally-safe refrigerant could well be the refrigerant of the future! The most important thing is to ensure yourself a good, tight and leakfree system by having your system installed by an EPA-certified technician from Manwill Plumbing and Heating L.C..

Condenser:
The purpose of the condenser is to house the compressor, condenser fan and condenser coils. Most condensers are approximately 30" to 36" in dimension and should be placed outdoors in a well-ventilated area. The fan on the condenser is designed to remove the heat from the hot refrigerant gases and allow the refrigerant gas to condense to a liquid form.

Compressors:
The compressor is the heart of the air-conditioning system. Located in the condenser, its purpose is to compress the returning refrigerant, build up higher pressure and send the refrigerant back to the evaporator coil in your ductwork. The two most common compressors are the scoll and reciprocating compressors.

The reciprocating compressor has been used in refrigeration systems for more than 50 years. It is comprised of a piston, crankshaft, piston rod, intake and exhaust valves. It is powered by an electric motor. All of these components are in a container smaller than a five-gallon bucket. Many consider the reciprocating compressor as the "old reliable" in the industry.

The scroll compressor is unique in that it is constantly compressing refrigerant versus the reciprocating compressor, which needs to withdraw the piston for the next compression stroke. The scroll type of compression is done with two inter-meshing scroll plates that constantly rotate in the same direction. The scroll has fewer moving parts and operates very smooth. It also is powered by an electric motor and is rather compact.

Warranties:
Every manufacturer warrants products differently. The compressor should have a longer warranty than the other components. Most compressors have either a five or a ten-year warranty. Parts warranties will vary from one to five years.

Protection devices

Filter/Dryer:
Designed to filter out contaminants or moisture that may enter the refrigerant system during installation or servicing.

High or Low Pressure:
Switch Senses the refrigerant pressures and protects the compressor against undue stress caused by excessively high or damaging low refrigerant pressures.

Time Delay Relay:
This prevents the short cycling of the compressor. A compressor that is allowed to turn off and be immediately turned back on, is subject to extreme stress. A time delay relay ensures the compressor will remain "off" for at least 90 seconds before restarting.
