Air Conditioning Systems

When the outdoor temperature starts to warm up, it is essential to  have a dependable air conditioning system. Modern air conditioners are designed to deliver the highest comfort at minimal fuel costs. When you replace an aging 8-10 SEER air conditioner with a new 18 SEER systems, you can save up to 50% on annual cooling costs.

Choices in Air Conditioning

Central air conditioners are offered in different configurations to address a variety of different job site conditions, including structural challenges, fuel availability and consumer performance expectations.

  • Heat Pumps can provide heating and cooling from one unit. If you are in an area with low electric rates, or do not have natural gas available, a heat pump may be the perfect choice. When switching from a gas or oil heating system to a heat pump you may feel that the heat pump is inadequate. Heat pumps generate heat out of the vents around 90-100 degrees where natural gas, propane or oil heat will produce heat out of the vents around 120-125 degrees.
  • When dealing with commercial buildings or residential applications with space constrictions, package units can be a perfect alternative as they are normally installed on the rooftops. If the application will accommodate a split type of system we find them to be more reliable, more flexibility on efficiency ratings and have better warranties than package units.
  • Split Air Conditioners are named for the split systems within that are separated by condensing unit (or coil) and air handler.

We can also offer ductless or ducted mini split options that have become a popular item recently. Ductless options increase efficiency when compared to conventional heating and cooling. These products are offered through Mitsubishi and American Standard and are extremely reliable.

Air Conditioning Installation

A successful a/c installation starts with a properly designed unit. Our knowledgeable technicians will analyze the perimeter and air distribution network to determine what is precisely needed for every room in the building. We run our total set of load calculations based on ACAA Manual J for every heating/air conditioning system we install.

Before your actual AC installation, we will create a construction schedule that is designed to minimize the disruptions of our customer’s lifestyle. We also ensure to focus on sealing the ductwork and tightening connections to make sure all specifications are met or go beyond what is required.

Air Conditioning Service & Repair

We all know it is cheaper and easier to prevent a problem, rather than to have to fix one. Air conditioning systems have a lot of moving parts and require regular maintenance to ensure they do not break down. When your unit does require repair, we will utilize your time and money by having our experienced technicians — equipped with advanced diagnostic equipment — to quickly identify the faulty components. We will be able to restore any make and model to working order and when the job is done, we make sure your invoice never exceeds our final estimate.

Heating Systems

When you’re looking to make a significant investment in indoor comfort, a new furnace or heat pump is a great option. While the quality of the equipment is important, the quality of the installation has a major impact on overall performance and the cost efficiency of the unit. Allow A Degree Above to help you by guiding you through every stage of the equipment selection and installation.


Forced air furnaces are designed to provide a great flow of warm air flow for your home and a more consistent temperature. There are a few different features that you can get with a forced air furnace:

  • Modulating or Two Stage Gas Valve with Variable Speed Blower (This is the most efficient set up in a gas furnace that is available. This is also where the utility company and federal government offers rebates or credits.
  • 80% efficient (Typically what you will find if a system is located in the attic)
  • 90%-98% efficient (Can be installed in an attic but steps will need to be taken to keep the furnace drain line from freezing in the winter since the furnace does produce water. Typically found in garages, closets and crawl spaces.)
  • The percentages represent how much heat is produced when you spend one dollar with the utility company. This does not reflect how much is delivered into your home. This is why delivered efficiency is so important.

Heat Pump

Heat pumps are designed and operate similar to an air conditioner. These systems have parts that will allow refrigerant to flow a different route through the system. This allows for heating and cooling to come from a single unit.

You should also be aware of limitations for heat pumps in colder climates. The efficiency of thermal transfer decreases when the outside temperature falls. This means that heat pumps are not usually installed in areas that experience sub-freezing temperatures. The good news is, air handlers can be equipped with an electric heat strip that will provide supplemental heating when the temperature is less than 40 degrees Fahrenheit. Typically, heat pumps are a very viable option for our customers in Dekalb County and surrounding areas.

Heating Repairs

Heating and cooling systems are the most important, and expensive piece of equipment in your home and they probably consume the most amount of energy! When a piece of equipment is this important, it should receive regular attention so that it can operate properly. With homes, especially homes with children and elderly family members, a reliable heating appliance is not just a preference, but a necessity. It is very important to contact an experienced heating contractor like A Degree Above when your furnace or heat pump breaks down or needs regular maintenance.
