Your HVAC system may look simple, but it is the sum of several parts that work in tandem to keep your home’s internal temperature at a comfortable level. You can always ask a heating and air condition service in Allen, TX to make repairs to fix an issue but if your system has seen better days, it may be time to replace it with a modern model.

Before asking a heating and air condition service in Allen, TX to recommend types of units you can get, you should be aware of the components that make a HVAC unit run efficiently. Here are some of them:

The Thermostat

You must be overly familiar with this part of your HVAC system since it is the piece with which you interact with the most. These are usually installed on walls as you know but what you may not know is that these are available in types – namely programmable and manual.

When the internal temperature of your home gets too cold or hot, it signals the HVAC system to start circulating air. A heating and air condition service in Allen, TX can help you determine which one you should go for depending on your budget and needs.

The Furnace

The furnace is what makes the HVAC system work and it can be large or medium in size depending on the size of the unit. However, as a heating and air condition service in Allen, TX will tell you, it will require the most space compared to the rest of the components.

The furnace heats air which is then distributed throughout your home via the ductwork or pipes. Depending on the type you get, this will be done via solar energy, combustion or heat pumps.

The Evaporator Coil

This component is responsible for cooling down warm air if the thermostat is set to a lower temperature. The cold air is distributed throughout your home which can feel heavenly during the summer. If the coil is not doing its job, it may be time to call in a heating and air condition service in Allen, TX to replace it or fix it.

The Condensing Unit

This is one of the first things that a heating and air condition service in Allen, TX will check out if they are called to make repairs or to conduct a routine maintenance job. This unit is located outside your home and it contains refrigerant. When this cools down, it is pumped to the evaporator coil where it transforms into a gas again.

The Vents

These outlets spread the heated and cool air that comes from the pipes or ductwork into the rooms around your house. These are usually located right near the ceiling and are in the form of angled slots which direct the air downwards. Call a heating and air condition service in Allen, TX to get them checked out regularly so that they don’t get blocked.

The Refrigerant Lines

As the name implies, these lines are designed to carry the refrigerant into the condenser. That is where the gas transforms into a liquid and is then pumped into the evaporator coil.

Types of HVAC Systems

Now that you know what makes a typical HVAC system work, you can make an informed decision for purchasing a new one. However, asking a heating and air condition service in Allen, TX for recommendations is also a good idea. Here are some systems they may suggest:

Forced Air Units

A HVAC system that is based on a forced-air model is designed to distribute heated or cool air that is produced by a furnace or AC respectively via a fan called a blower. As the name of the system implies, the blower forces air through a series of metallic ducts that are installed around your home. If for instance, warm air is forced into a room, colder air is forced out from other ducts and straight into the furnace to be warmed. If the blower breaks down, you should call a heating and air condition service in Allen, TX to get it fixed or replaced.

Gravity Units

Gravity units are based on the fact that hot air rises while cold air remains down. Needless to say these systems cannot be used to circulate air from an AC. The furnace is usually installed near or below the floor and the warm air that it produces flows through the ducts to registers that are present in the floor.

If the furnace is installed on the main floors, the registers are usually installed on the walls as high as possible so that the warm air that rises to the ceiling can be picked up easily. Once the air cools, it sinks down to the bottom again, re-enters the ducts and then goes back to the furnace where it is heated again. Usually, the heat source is water which is boiled in the furnace and circulated via pipes.

Radiant Units

Radiant HVAC systems work by warming up the dimensions of rooms and it usually does this by warming up the radiators placed in each. These are quite sufficient in warming the air but some systems may also use electric heating panels for the same function. However, a Radiant system cannot be used to circulate cool air from an AC.

These units are usually found in old homes and are connected with hot water systems to function which make them quite similar to gravity units. Modern radiant systems are usually built into houses during the construction phase on a concrete foundation. Pipes are installed under the foundation and when the concrete it is made of is warmed, it warms up the floor.
