Once warm air inside your home blows across the indoor evaporator coil, its heat energy transfers to the refrigerant inside the coil. That transfer, in turn, “cools” the air. The refrigerant is pumped back to the compressor where the cycle begins again. The heat absorbed by the refrigerant is moved outside your home while cooled air is blown inside. Moisture that contributes to humidity is also condensed out of the air. Your cooling system is usually combined with your central heating system because they share the same ductwork for distributing conditioned air throughout your home.
When central air conditioning service fails during a heat spell, you may have to wait days for an HVAC repair technician or a ac contractor to show up, and you’ll probably pay at least several hundred for the repair. But if you’re comfortable working around electricity and are willing to spend about $50 on parts, you can probably repair your air conditioning service yourself in about two hours and save about $225 on parts markup and labor.
A more efficient method of controlling humidity is to use the waste heat from the refrigeration cycle itself. Instead of rejecting the waste heat outdoors, the heat is directed inside when humidity control is required. One form of heat reclaim is called hot-gas reheat or “refrigerant desuperheating” where refrigerant is passed through a heat exchanger located downstream of the cooling coil. The hot high pressure vapor leaving the compressor passes through this heat exchanger prior to entering the condenser coil. This in turn heats the indoor air and again causes the AC system to run longer to meet the thermostat set point. Although more energy is used, this is much more efficient than turning on an electric heater. Another form of heat reclaim is called sub-cool reheat. This strategy takes the warm liquid refrigerant from the condenser and passes it through a heat exchanger located downstream of the cooling coil. Less heat is available using this method because the majority of the heat has already been rejected at the condenser. Since more energy is used to pump liquid (as opposed to a gas) through the heat exchanger it would appear that this method is less efficient than the hot-gas method, however, the liquid in the heat exchanger is sub-cooled in the cold supply air stream which increases the capacity of the air conditioner. Since more capacity is available, the AC units is able to meet the thermostat more quickly.
I need a complete system replacement , before I was trying to get an evaporator coil replaced , of course the price is between $2200 an $2800 , then get told it probably will over tax my ac unit within months , so now and like everyone else what do you buy 14 ,15 16 17 seer units ,price and how do we know its reasonable  why can't there be '" a estimated price ,in the ball park, a range of prices ,so we can at least go from their .....  Now it's from 7500 to 15000. Frustrating  from the start so everybody good LUCK.   Draw a # from the hat    Unregulated  and who do you BELIEVE, just like on NCIS go with your gut feelin

Seasonal checks. Once a year have a licensed professional change all filters, clean and flush the coils, drain the pan and drainage system, and vacuum the blower compartments. The contractor should also check to make sure that the system is properly charged with refrigerant, that there are no leaks, and that all mechanical components are working properly.
In 1902, the first modern electrical air conditioning unit was invented by Willis Carrier in Buffalo, New York.[citation needed] After graduating from Cornell University, Carrier found a job at the Buffalo Forge Company. There, he began experimenting with air conditioning as a way to solve an application problem for the Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York. The first air conditioner, designed and built in Buffalo by Carrier, began working on 17 July 1902.[citation needed]
When a gas furnace is not in operation, most send a steady, wasteful draft of warm household air traveling up the venting system and out the roof. The Rheem Classic® Series and Classic® Plus Lines – with AFUE ratings of 78% and better – feature an induced-draft blower that works in conjunction with a hot surface ignition system to pull hot gases through the heat exchanger at a constant and controlled rate of flow. As the burner cycles off, the draft blower stops, keeping the heating air in the system.
If you believe that the ac not working or you’re getting little or no cold air, check these three things first. Make sure all the registers in the house are wide open. Then be sure the furnace filter is clean. Then go outside and clean off the condenser coils (Photo 2). If several registers were closed or the filter was clogged, the reduced airflow could have caused the evaporator coil to ice up and stop cooling your home. If you’ve changed the filter and opened all the registers and you’re still not getting airflow at the registers, deice the A-coil. Move the thermostat mode switch from “Cooling” to “Off” and move the fan switch from “Auto” to “On.” Let the blower run for at least 30 minutes or until there’s good airflow at the registers. Then turn the AC back on to test it. If it works for the next 12 hours, you’ve solved the problem.
Air handlers and furnaces aren't often found together. If you have a furnace you probably don't need to think about an air handler. Air handlers tend to be paired up with heat pumps and help manage air flow throughout the building. Some models also provide secondary heating and cooling parts to help out the heat pump. A furnace works on a different concept. Instead of an air handler, furnaces have included blowers that move the warmed air into your ventilation and disperse through your home. Since furnaces have combustion chambers and create heat, they don't have some of the parts you'll find in a typical air handler.
While repair is often the preferred choice, problems like a consistent repeating complication or extra-costly furnace repair parts might start leading you in a different direction. Remember that repair is only the preferred option when the cost of seeking it makes sense! If you’re shelling out for repair every single year, then it might be time to talk to your heating contractor about furnace replacement.
Inside the unit, the air passes over the evaporator coil first, and is cooled and dehumidified. The now dehumidified, cold air then passes over the condenser coil where it is warmed up again. Then the air is released back into the room. The unit produces warm, dehumidified air and can usually be placed freely in the environment (room) that is to be conditioned.

Mr Manns did a great job of explaining what he was doing. I learned some new things. One request: before using the hose, please ask to use it. In my particular case, the spicot is misbehaving. I have a particular method for turning it on/off to minimize aggravating the problem. So while there are no problems with him using it, I want to turn it on and off but was not given the opportunity to do so.

Air duct cleaning is done by heating, ventilation and air conditioning (HVAC) professionals. The pros use industrial-strength, truck-mounted vacuums and powerful brushes and hoses to clean inside the metal ducts that make up your forced air heating and cooling system. The Environmental Protection Agency recommends duct cleaning if there is “substantial visible mold growth inside hard surface ducts, ducts that are infested with vermin such as rodents or insects, or ducts that are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.”
Outdoor Fan Motor -- The outdoor fan, also called the condenser fan, is exposed to external conditions. As such it is most prone to dust and debris and the extreme weather. In desert climates, the outdoor fan motor is subject to heat not only from normal operation but from the outside temperature as well. As it starts to fail, the fan may work fine in the cooler morning hours but stop by afternoon. This can shut down the entire system for hours. When they stop running completely, your air conditioner will no longer work. Running a faulty fan will lead to compressor failure, which is a very costly repair.

Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
The compressor-based refrigerant systems are air-cooled, meaning they use air to exchange heat, in the same way as a car radiator or typical household air conditioner does. Such a system dehumidifies the air as it cools it. It collects water condensed from the cooled air and produces hot air which must be vented outside the cooled area; doing so transfers heat from the air in the cooled area to the outside air.
