Do you know your HVAC System?

There are many things you should know about your heating and air system before trying to find HVAC contractors in Wilmington NC. If you do not have the knowledge needed to ensure your heating and cooling contractor can provide the best customer service and to have your air conditioning and heating system fixed properly do not worry. I have prepared the following guide for you to explain the most important parts of your central air system.

Introduction

Before looking to bringing a North Carolina HVAC contractor into your home, you need to understand the fundamentals of the HVAC system. I have prepared the following article to help you understand the 10 things you should know about your HVAC system.

Heating, Ventilation and Air Conditioning (HVAC) is a technological break-through in mechanical engineering that aims to not only give comfort thermally but also provide an acceptable quality of air indoors. HVAC is a fundamental part of both residential property owners, industrial and office spaces and marine environments. Residential areas include, but are not limited to, family houses and buildings that house apartments and hotels.

These areas use clean and fresh air from outside to regulate both temperature and humidity to maintain healthy building conditions.

How do Heating & Air Systems work?

The heating systems basically comprise of three parts;

• The source of heat

• The distribution channel for the heat

• The system of control.

Let us look at the heat sources first. Ordinarily, there are three sources of heat for a home;

The Furnace System

The fuel type in your local area would determine the furnace type in your home. You could always choose to switch to the oil or propane gas furnace from the oil furnace.

To give you a better idea on how your furnace system works, I have prepared the following video for you.

The Boiler System

The water can be heated in three different ways; radiant floor systems, coils or radiators. When choosing to buy a new boiler for your residential area, consider the following;

Size

The climate of the area where the residential space is located in the most important factor to consider when picking the relevant size. The colder the area, the bigger the boiler and the converse holds.

Efficiency

The annual fuel utilization efficiency (AFUE) determines the efficiency of the boiler. AFUE works by measuring the boiler’s efficiency in the conversion of the energy inherent in the fuel to heat during a particular year.

Venting

The ventilation of residential space is of paramount importance. You should be familiar with the regulations governing the gas boilers. To get assistance with issues with regards to ventilation and the prevention of poisoning resulting from carbon monoxide, consult with an HVAC technician.

The Heat Pump System

The heat pump system is not only part of the central heating system but also part of the central cooling system. The pumps use the air outdoors to cool a house during summer and warm a house in winter. They can be defined as an appliance that is mechanical in nature that moves heat from a source to the end. Heat pumps are generally divided into three; ground source, water source, and air source. The preference of heat pumps stems from the fact that a unit is enough to warm a house.

Going into Air Conditioning

Generally known as A/C’s, they move the heat from one point to the next. The fundamental components of the air conditioners are; the condenser unit (located outside) and the evaporator unit(mounted on either the furnace or the air handler). They cool the house by extracting heat from the air in the room through technology that is used in refrigerators.

There are three types of air conditioners for a home:

Central Air Conditioners

With a lifespan of between 15 & 20 years, the central air conditioners cool the rooms through the circulation in systems of supply and return ducts.

• Window/ Room

These have life spans of between 10 & 15 years. Popular for their energy efficiency, they are installed to your house’s windows.

• Mini Split systems

Popular among owners of homes with boiler systems, they allow for zoned cooling without the hassle of ductwork. They have a lifespan of between 12 & 15 years. They also have the advantage of being able to be installed in either new or old homes.

And finally, the control system

The system of control is ordinarily a thermostat. This regulates the heat amount that is to be in distribution. There are a range of thermostats that are suitable for any lifestyle;

• Manual thermostats

As the name suggests, the inside temperature is manually adjusted to fit how cold or how hot you want your home to be.

• Programmable thermostats

The thermostats are designed in such a way that there is a program for heating or cooling your home. The drawbacks vary from one model to another.

• Smart Wi-Fi

Unlike the programmable thermostats, these ones allow for complete customization of the heating and/or cooling schedule. The settings can be monitored from any compatible Wi-Fi device.

Understanding the basics of the HVAC make up the first three factors that an HVAC contractor hopes you know about before bringing him/her into your home. The other seven include;

• The amount of time you need to replace the system

The choice to be made depends on the needs that are immediate, the ability to buy and the preferences. A window air conditioning unit would more suitable if the needs that are immediate are safety and health as you figure out what you need to get the system replaced.

• The decision on whether you need the system repaired or replaced

The question is best handled by a contractor that is qualified. The factors that are important are the age, the frequency in which the system operates and the location of your residential space.

• The amount of space that needs to be cooled and/or heated

The residential space needs to be analyzed by a professional so that any additions to the house are adequately covered. Square footage is not the only relevant factor, as usage and comfort come in handy in the analysis of the load.

• The need for either just cold or hot air or something more

Additional features of a system that is very efficient include lower monthly electricity bills that would offset the initial cost of the installation. Another factor that needs to be considered is the comfort. Comfort stems from the additional benefit that is humid control. This is provided by high-efficiency systems.

• The trends in the air conditioning space

If you’re looking to replace the system, you should consider the following trend. The geothermal systems use the temperature that is usually cool from beneath the ground to cool the house in place of the hot air outdoors.

• The investment in a programmable thermostat

The programmable thermostat is a quick and simple way of reducing the costs of energy. The fact that they can be programmed allows you to control the thermostat automatically for times you know you will not be in use of it at home.

• The choice of the contractor to hire

The most important thing a contractor would want you to know is how to settle for the right contractor. You could choose to consult organizations that provide certification for technicians such as NATE and ACCA. For review from other users, you would head to third-party websites such as Angie’s list for HVAC contractors. The most important factor is a contractor who takes your feedback very seriously and uses it to improve your HVAC experience.
