Are Rooftop Units The Most Efficient Type Of HVAC System

Self-sufficient heating-pump unit and air conditioning system are the two most popular cooling technologies in the United State’s commercial building facilities. The system is mostly installed on the rooftop and comes with high energy efficiency. The rooftop units are also known as the package unit, or air conditioners are machines produced in large numbers. These machines include air-handling fans, cooling equipment, electric or gas heating equipment, and more. The sizes of the RTUs systems differ from one to another. The ac capacity can be as small as 1 ton or as big as 100 tons.

A look at the efficiency of the rooftop unit in the HVAC system

The availability of the RTUs is in several efficiencies. There is also increasing effort to enhance the efficiency of the system, and create a kind of retrofit options. These are the options that will be able to improve the efficiency of the units installed. The efficiency of the RTUs can be lowered through low maintenance practices. It can also be affected by an inability to handle the system operation.

The RTUs performance metrics are what you need to know to understand its overall efficiencies.

The Seasonal Energy Efficiency Ratio

The Seasonable Energy Efficiency Ratio ( SEER) is the adjustable rating according to load in the residential representative. The seasonal energy efficiency ratio applies to the rooftop units with 5.42 tons or lesser cooling capacity.

Energy Efficiency Ratio

The energy efficiency ratio (EER) measured in Btu per hr is the cooling rate divided by the power at a full-load condition measured in watts. Many things are included in the power measurement, and they include controls, fan motors, and compressors.

The Integrated Energy Efficiency Ratio

The integrated energy efficiency ratio ( IEER) defines the total operating efficiency at the one hundred percent, seventy-five percent, fifty percent, and twenty-five percent operating loads. The energy efficiency ratio will determine the rooftop unit that will work more efficiently.


With the various operating efficiencies associated with the rooftop units, it is easy to conclude that the 

RTUs is the most efficient type of Heating, Ventilation, and Air Conditioning System. It is the system that requires low input to get a massive result in forms of thermal comfort in a building and more. That can explain the reason for the increasing number of organizations and public facilities with the RTUs system installed.

Great Option For Home HVAC: Radiant Heating

Radiant heating systems are used to  heat several part of a house such as the floor, ceiling and walls. The main reason for this heat transfer is through radiation. Radiation allows heat to travel directly from the hot surface to other parts of the house with people and objects as well. An example of radiant heat is when you feel heat from lighting a campfire. When radiant heating is located in the floor, it is often called radiant floor heating or simply floor heating. There is also radiant heating for ceilings and walls.

Things to know about Radiant heating

Radiant heating and cooling is a component of HVAC system that exchange heat through radiation with the environment. Radiant heating is efficient because it doesn’t make use of traditional duct work. It is also preferable amongst people with allergies as it doesn’t circulate air like other systems.

The benefits of the radiant heating

As much as radiation is important in radiant heating, convection also has its role to play. Convection is the movement of heat with an area as warm air is rising. There are a whole lot of benefits that radiant heating provides to your home. Some of these benefits include the following:

  • Reduced noise while operating
  • Reduced allergens
  • Energy efficiency

How A Building’s HVAC Systems Stay On The Same Page: Networking

HVAC stands for heating, ventilation, and air conditioning. It is the system responsible for the comfort of people at home and offices. The installation of the HVAC system is done in one place and connects to the entire building via networking. 

Most people wonder how the system is networked to reach out to the entire building. If you are wondering about the same thing, there is no need to worry, as the answer to the question is readily available here.

The truth about the HVAC system you need to know

HVAC is a technology made for the purpose of indoor comfort. The aim of this system is to improve indoor air quality and achieve thermal comfort. The design of the HVAC system is based on the thermodynamics principle, which puts it in the same category as mechanical engineering. It is also following the principle of heat transfer, fluid mechanics, and more.

The HVAC district network and what you should know

One thing about the HVAC system is that it is executed in one building and utilized in the entire building for effective indoor vehicular comfort. The system is designed in such a way that each building gets different features. The system sends chilled water to the building for the cooling system and warm water for the heating system. These are possible through a district networking system.

The truth about the HVAC networking system

Through the use of internet technology, the HVAC system is not made to communicate both with the close-by system and with the surrounding buildings. More so, this system is constructed to communicate with enterprises and commercial building systems to ensure indoor comfort at a reduced cost.

The HVAC distribution via a network system 

The essence of the HVAC is to produce clean and fresh air. It is to give those making use of the system an opportunity to benefit from the comfortable temperature. The fresh and clean air is directed into the home from the central system for distribution. The flow of fluid through the system follows a networking concept. It is done via duct network and channeled to different rooms. The modern system has an improved network channel that enhances the distribution and flow of warm or chilled fluid to the building. So, one HVAC system can serve multiple buildings with the help of an effective network connection system. Users of this system will enjoy comfort at an affordable rate.

The Most Important Parts In An HVAC System May Be Gas Sensors

Gas sensors or detectors are devices mainly used to detect and identify different types of gases. They are commonly used in facilities to identify gas leaks and they can also be used as smoke detectors in residential homes. HVAC systems can be very complex since their primary purpose is maintaining quality fresh air throughout an area. The quality of air has to be constantly maintained due to the amounts of carbon dioxide and carbon monoxide. Any slight change in the amount of these gases can have an impact on the safety and comfort of the occupants or workers in the building.

The things to know about gas sensors

Gas sensors are usually connected to an alarm system which makes sure you’re aware of any significant changes to the level of potentially harmful gases in your home or workplace. Due to the fact that gas sensors are constantly monitoring a variety of gases, it’s always a good idea to calibrate your sensors regularly. Doing so helps the sensor perform operations more accurately and consistently.

How to read the gas sensors

Gas sensors can easily measure the CO2 concentration in the atmosphere or inside a building ensuring that everyone within the area has the optimal amount of gases for safety and comfort. Gas sensors are also important as they help detect harmful gases that may cause explosion or gas poisoning. As human beings, we need oxygen to survive. So it comes as no surprise as to why gas sensors are useful to us. Reduced oxygen levels can cause loss of consciousness and dizziness in inhabitants. If not dealt with immediately, it can even cause death or hemorrhaging. Low levels of oxygen can be caused when another gas displaces the oxygen around it.

The need for gas sensors in the industries

For industrial workers, gas sensors might just be the only way for them to identify issues pertaining to gas leaks and threats. These devices can be vital to safety as they can easily detect low levels of oxygen and gas leakage which may be toxic to workers. Without these sensors, workers are easily prone to toxic gases which can cause a lot of health problems for them and even death.


Carbon monoxide is a well known toxic gas capable of killing humans. It is odorless, colorless and tasteless which makes it extremely hard to detect. Carbon monoxide or CO is produced when carbon based fuel burn in a tight space and is unable to escape. It’s produced in places such as a furnace, oven or fireplace.

Do You Have To Clean HVAC Exhaust Outlets?

Exhaust outlets in buildings are responsible for expelling heat created by the heating system of your HVAC. Exhaust systems are mostly preferred during cold weather conditions. If the weather is warmer, this can cause moist air to condense and cause mold growth. There are several types of exhaust systems in your house used to remove heat or combustible gas from the home although they still share the same function which is to move air from indoor rooms and expel it outside the house.

The need to clean exhaust outlet

So why do you have to clean these exhaust outlets? HVAC stands for Heating, Ventilation and Air Conditioning, it either heats or cools the air inside your home or filters away harmful particles that can cause medical issues to occupants. Exhaust outlets are usually found in kitchen and bathrooms. These are fans that are simple and easy to install. These fans can malfunction without proper maintenance. However, if they’re well maintained, they can surely make your home comfortable, safe and energy efficient.  When these fans operate, they remove heat and humidity caused by activities in the area. Without proper care, your exhaust outlet may cause the following:

  • Increase in Energy cost
  • Poor air quality
  • Mold and mildew growth
  • Harmful particles and dust

The dangers of malfunctioning exhaust outlets

If your exhaust outlets are poorly functioning, this can put a great deal of stress on other parts of the HVAC system leading to paying more money in energy bills. As time goes on dust, moisture, and other harmful particles can get clogged in the ducts of your exhaust system. When the mold and mildew contaminates your outlets, these harmful particles can easily be spread through different ducts leading to different areas in the building. Ultimately, the occupants in the building are bound to get sick as there is a high level of allergens and spores causing allergic reactions and respiratory complications.

Improve fluid circulation with proper cleaning of exhaust outlets

Dealing with the dirt inside your exhaust outlets can help improve the quality and circulation of fresh air and can even reduce energy and heating costs. In terms of saving energy, it’s good practice to switch off the fans when they’re no longer needed.  Cleaning the fans routinely may help extend the life span of your system although the average life span is about 10 to15 years. In case of any mechanical or electrical damages, consult an HVAC professional technician on the matter.

Who Can Make Do With A Single-Stage HVAC Setup?

Single stage HVAC systems are very common. Having a single stage heating or cooling system means that your air conditioner or furnace has only one level of cold or hot input. Single stage HVAC systems generally have a furnace or boiler and an air conditioning system. Multi stage HVAC system is a little bit different from single stage systems. These systems have several outputs for heating and cooling.

Things to know about the HVAC setup

A single stage HVAC setup might be right for you although there are factors involved such as location, size of house and budget. Single stages HVAC systems either run at full capacity or it doesn’t run at all. There also several reasons as to why you might prefer a single stage system. Some of this reason includes the following:

  • Easy to install and maintain
  • Cost effective
  • Less complicated

HVAC Installation tips you should know

Installing a single stage HVAC system isn’t so difficult and its price can vary depending on the ac unit you are purchasing. Compared to multi stage systems, single stage systems typically cost more due to their complexity. Because a single stage HVAC system is either ON or OFF, operating it is a piece of cake. If you don’t need it, simply turn it off and if you need it, just turn it off. Handling a single stage HVAC setup doesn’t require a lot of experience and pretty much anyone can handle it.

The advantages of the single stage HVAC system

As single stage HVAC systems have its advantages, it also has its disadvantages. One of these disadvantages is the fact that single stage HVAC systems don’t really give you a lot of control. Since all you have to do is turn it ON and OFF, it’s almost impossible for you to get the desired conditions and settings. Also because of the lack of control, it’s definitely suitable for all places with high levels of humidity.

The need for the single stage HVAC system

Having to install a single stage system is cost effective; however paying back the electric bills can be an entirely different story. Due to its lack of customization, single stage systems are not capable of saving energy compared to multi stage systems. As a result, you get to pay higher electric bills.


A single stage HVAC setup has its own problems. This doesn’t mean that it is unsuitable for all areas. As we mentioned earlier, enjoying a single stage system depends on the size of the house, location, budget and other factors.
