Everything You Need to Know About Heating & Air Conditioning Columbus, Ohio

HVAC stands for Heating, Ventilation, and Air Conditioning and is responsible for controlling the heat and air flow of a space. These can range from the air conditioner at home to the huge systems found in apartments, business establishments, office buildings, and industrial complexes. An efficient HVAC system provides indoor comfort by stabilizing thermal comfort. Its design follows the principles of thermodynamics, heat transfer, and fluid mechanics. Here are the basics you need to know about heating and cooling in Columbus, Ohio.

Components of an HVAC System

The ‘H’ in HVAC

Cool air is distributed via air conditioners and heat pumps. When the air conditioners and heat pumps are in the cooling mode, the heat is eliminated in the room and keeps the warm climate in your home during the cooler months of the year. These systems use refrigerants to cool the air inside a building and to remove excess humidity to provide air in a space.

This process is the same only in reverse for heating. There are several types of heating systems, with the forced air system as the most popular. However, many homeowners also use geothermal or radiant heating systems. All these systems create heat at a central source and distribute it throughout the home via different methods.

The ‘V’ in HVAC

Ventilation replaces the musty and stale air inside the building with fresh air. It eliminates some of the dust, heat, carbon dioxide, and moisture inside the area and replaces it with fresh outdoor air. It improves the air quality by removing the excess humidity inside a building, making it an effective humidifier.

The Thermostat

The control component of an HVAC system, the thermostat controls the heat and air conditioning. It allows you to set the required temperature at a specific time for each room. It maintains the programmed temperature at the set time giving assurance that utmost comfort is inside your home. To regulate the temperature, you only need to press a button to attain your desired heating or cooling levels.

Different Kinds of HVACs

Keeping your home comfortable and livable is the main function of an HVAC system.

The Split HVAC System

This traditional type of HVAC has components that are fitted both in the internal and external area of your home or a building. They are optimized for the best heat and air flow. It includes a furnace, an air conditioner or a fan coil, an evaporator coil, and a heat pump system.

The Packaged HVAC System

These systems combine several components found in a single unit. Having a compact design, it is ideal for homes and building with no provision for the separate parts of a split HVAC system.

The Ductless Split HVAC System

This system is perfect for heating and cooling room additions or other areas, such as home theaters, garages, and exercise rooms, where installing or extending ductwork is not possible. It is a HVAC choice for homes with small spaces.

The Hybrid-Heat Split HVAC System

This system determines the external air temperature and chooses the fuel source that is the most economical for the condition. It includes both an electric heat pump and a gas furnace. It can also work to cool the air inside your home in spite of its name.

The Geothermal Heat HVAC System

These systems are the most cost- and energy-efficient systems available in the market today. They tap into the reliable and moderate temperatures of the earth to cool or heat your home.

The Air Conditioner: A Modern Luxury?

Air conditioners have been around for ages since it was invented by Willis Carrier in 1902.  Since then, the use and improvement of air conditioners have come a long way, and its usage has become increasingly popular. So is the air conditioner a modern luxury or a necessity?air conditioner modern luxury

Come to think of it, our great grandparents have lived without it. So, what makes it so much a seemingly necessary appliance?

The Importance of  the Air Conditioner in Our Life

As the population grew, and modernization continued its momentum, more and more uses of the air conditioner have evolved.

More than the comfort of a cooler air, the air conditioner has made a lot of things possible since its invention.  For one, having air conditioning has made architectural structures with more compact designs possible. This makes for a more efficient use of space particularly of offices in an ever-growing population. It also makes possible the large gathering of people in a compact area. Air conditioning also provides comfort for office workers which of course results to greater productivity and over-all well-being. Laboratories and hospitals (at least in the critical areas such as operating rooms) cannot exist without air conditioning.

Summers are also getting warmer, and from a luxury, an air conditioner has become a necessity if we are to preserve our well-being, overall disposition, and health.

The Downside

The big question is the growing over dependence on air conditioners, which of course, has a downside.

In the US alone, cooling America’s architectural structures and vehicles means an additional half a billion metric tons of carbon dioxide released into the air annually.

This is becoming a global concern, and we can all do our part by minimizing our overuse of our AC units. Even turning the thermostat a degree or two up will have a good impact on the environment.  Proper maintenance of our AC units also helps. Air conditioners have also evolved in such a way that AC units have continued to improve.  They have become more energy efficient and thus, beneficial to the environment.

The bottom line is, while an air conditioner has gone from a luxury to a necessity, we need to do our part. Conscientious use and maintenance of our air conditioner will collectively benefit us all, from lower bills to a better environment.

The HVAC Homeowners Guide

HVAC System Columbus OhChoosing / Buying the Right HVAC System

This HVAC homeowners guide should help you with making the right decisions with your home HVAC. Whether you are replacing your old HVAC system or buying a completely new system, the first step is determining the current heating and cooling needs in the household. The primary consideration is, of course, the sizes of the areas/rooms, but there are other things to look into.  Does the house have sufficient insulation? How about the placement of doors and windows and other construction materials used? For example, the more glass area the greater the heat transfer during warm months or heat loss during cold months. Thus, calculating the right HVAC system for your home will spell the difference between energy efficiency and long service of your HVAC unit or inadequate or inefficient heating and cooling or utility bills that run unnecessarily high.

Efficiency Ratings of HVAC Systems

After determining the right capacity of the HVAC System you need, the next thing to look into is the efficiency ratings of HVAC units.

Air Conditioning Systems – When scouting for air conditioning units, check the Seasonal Energy Efficiency Ratio or SEER.  The higher the SEER (15 or more) the more efficient it is and the less energy it uses.

Boilers and Furnaces – When shopping for boilers and furnaces, check the energy efficiency rating which is a measure of how efficient these devices are in converting fuel to heat, or the Annual Fuel Efficiency  (AFUE) rating. The higher the rating, the more efficient the system is and the less energy it consumes. Hence a rating of 90% means 90% of the fuel is efficiently converted to heat.

Heat Pumps – When looking for  a good heat pump, check the efficiency rating otherwise known as the Heating Seasonal Performance Factor (HSPF). The higher the HSPF, the more efficient it is. A rating of 8-9 HSPF is already considered very good.

Use and Maintenance of Your Heating and Cooling System

When operating your HVAC system, keep the temperature settings within the recommended level. This way, you avoid using excessive energy and unnecessary wear and tear of your system.

For the heat settings – keep it between 68° – 72°. Each additional degree can add 3% to the amount of energy needed for heating.

For the cooling settings – keep it between 70° – 76°.

Other tips include:

  • Using insulation to help in cooling the room, or using drapes to block off heat from the windows
  • Changing air filter as recommended for the type of filter
  • Having a professional contractor inspect, clean and make adjustments as necessary in order to ensure efficient operation of your system for years to come.


What You Need to Know About Central Air Conditioning

central air conditioningIs this summer heatwave melting you into a puddle on the ground? A lot of people can make it through the warm,  Midwest seasons using only window or portable A/C units. Some get by with just fans. If those aren’t enough to make you comfortable, it might be time to consider having central air conditioning installed.

How Central Air Conditioning Works

Central A/C allows cool air to flow through a system of supply and return ducts. The supply registers and ducts transmit cooled air from the A/C unit throughout your home. As the cooled air circulates in your home, it becomes warmer and flows back to the central A/C via registers and return ducts. This system is one of the most common and efficient ways to cool your home.

If you plan to have a central air conditioning unit installed, the size of your home will determine the size of the unit you’ll need. It is also essential to have the correct size duct work so that the cooling needs of every room are met. The system can be inefficient if ducts are leaky or not insulated. Every seam and joint must be properly sealed. Adding a central AC system can cost less if you already have heating ducts. But remember that the ducts used for heating might not be in the right location or size for optimal cooling.

A central AC unit features a condenser placed outside your home and a fan-and-coil system that is connected by pipes carrying refrigerant. The most common design of a central A/C has the refrigerant circulating between an interior coil and a corresponding exterior condenser with compressor. The air is cooled by the refrigerant and is dehumidified in the process. The air is then circulated by a blower through the ducts all over the home.

Adding a central air conditioner can be expensive, especially if there are no ducts in your home; but most homeowners agree that it’s worth every penny. Contact American Air to have one of our HVAC specialists asses your needs and give you an estimate.
