the Home Air Conditioning Systems fundamentals


Depending on your home’s needs, you can choose different kinds of air conditioning systems. Here are some fundamental hints to learn how to preserve the standard AC systems.omm


The first air conditioning system invented by Willis Carrier in 1902—but the purpose was not to make the air fresh. The goal of his invention was to dehumidify the air in a sheet factory so that it prevents the paper from curling in the humid atmosphere. Dehumidification plays a vital role in comforting the atmosphere.

Let’s understand how the AC works?

Air conditioners, composed of layers or circles of copper or aluminum tubing, use fans to push inside air over a cold surface. Since the coils cool the atmosphere, its moisture decreases on the reels and will disappear.

Refrigerant, which the compressor pumps it through protected lines to a condenser located outdoor, cools the coils. Refrigerants are fluids with a low boiling period, that is, the heat at which the refrigerant changes from a liquid to a vapour. It is the point that cools the coolant. This change appears at the coils in air conditioners, chills them and pushing heat from the interior space.

The refrigerant transfers to the condenser after leaving the coils, and the pressure of the compressor changes it from gas to liquid.

The change in the second stage makes the refrigerant stop the heat gained from the interior space. The refrigerant finds its way to the coil after moving into the condenser. Heat pumps produce wintertime heat in the same way that air conditioners eliminate it in the summer, except it saves the refrigerant flow.

Central AC Systems

Consider the needs of your home and pick different kinds of AC systems.


Central AC

There is central AC in most of the new houses. The ducts which use to keep the house warm in the winter provide cold air in the hot weather. The cooling loops might be near an air handler (big fans in the ductwork that transfer air) in the attic or the cellar or maybe in both.

Ask Romaheating’s HVAC Certified technicians to do a “Manual J” calculation whenever you establish a new system or an old condenser renewed. A Manual-J forecast estimates the home’s area, surrounding, solar heat gain from the windows, and leaking air. It’s a single way to understand the exact size of your condenser. The smaller a capacitor is, the less it would cool the area, and the larger it is, the less it can dehumidify.


A mini-split is a small central-air system that most of them run as energy pumps. A ductless mini-split has one or more wall-mounted captions flowing air, depending on the cooling needs of the home.

Mini-splits are a popular way because of their high-efficiency credit, which is to retrofit air conditioning in old homes as the first heating and cooling source. Ensure our certified expert does a Manual J estimation to size a mini-split properly in the central AC.

PTAC Units

People who have spent a night in the motel are familiar with Packaged Terminal Air Conditioning systems. PTACs apply in an opening in a wall and often provide heat. PTACs are common as reasonably rated methods to cool smaller places.

Window Systems

These systems place tightly by the top band of a double-hung window, the essential advantage of a window air conditioner is that it’s economical to purchase. In heat environments, they can flow a large amount of air, so you’ll want to take them every winter; otherwise, there will be massive air leakage.

Through – the – wall air conditioners are similar to window systems. The main exception is that these systems apply inside a cover placed on the wall and stay in position during the year.

How to maintain Your Air Conditioning system?


According to Romaheating’s company Certified technicians, The best way to maintain air conditioners is to clean the filters, so it doesn’t block the airflow. Central systems depend on the same renewable screens, like heating orders. But in the other methods, you can easily clean the filters using a vacuum.

Romaheating HVAC LTD recommends checking the outer part of the air conditioner. Be sure it is free from leaves and dirt.

Performance and Potential of Your AC system

All of the air conditioners except the small ones will measure in tons. The cooling potential of a one-ton air conditioner is the same as one ton of iceberg. We sometimes use BTUs to Sometimes to define potential. 12,000 BTUs are equivalent to one ton for cooling purposes.

It uses electricity to operate the compressor and fans that make an air conditioner run. The fewer watts of energy used to produce a ton of cooling, the higher the effective the air conditioner will be. It also refers to the Seasonal Energy Efficiency Rating or SEER. The more the SEER, the effective the system.

The minimum SEERs in northern states are 14 and 15 in southern states for the new air conditioners’ new standards, with less than 45000 BUT. t

These rules will be somewhat lower in the South for large systems. If you have a heat pump operated system, the SEER will be 15. The most available effective methods today have SEERs of 26 or more.
