Air Conditioners

Daikin AC Product

An air conditioner, also known as an AC, is the unit you see outdoors if you have a traditional air conditioning system. The modern air conditioning system was first designed by Willis Carrier in 1902 to address an application issue at a local publishing company in Brooklyn, New York. Once the benefits were fully recognized, it didn’t take long for this technology to be adapted for movie theaters and eventually. the home. Thanks, Willis, for keeping us cool! A common misconception about air conditioning is that it brings cool air into the home when in fact, as the air from your home flows over its evaporator coil, the warm energy is removed and travels outside, via the refrigerant and line set, to be distributed into the air. This leaves the cooler air to travel through your duct work to cool the living space. This is why often times when you put your hand above your outdoor air conditioning unit, the air coming off the coil and fan is warm. They are also great at lowering the humidity levels within the home by condensing the humidity in the air at the evaporator coil and removing the excess moisture through the drain line.

Heat Pumps

Heat pumps are very similar to air conditioners, except they have the ability to cool AND heat your home. During the cooling operation, it removes the warm energy from the air, just like an air conditioner. A heat pump’s operation can be reversed to take warm energy from the outside (even during cold days) and bring it inside to disperse into the home’s air to maintain warmth. All of this is accomplished through the outdoor unit, evaporator coil, and refrigerant lines. Heat pumps are most commonly partnered with an air handler in the southern states but are commonly found with gas furnaces in the northern states to create “hybrid” systems which utilize the electrical energy source of the heat pump and the natural gas, or oil, resource of the furnace to create a dual fuel system. A hybrid system is a great system to utilize the efficiencies of both energy sources while considering cost. It is important to note that there is only enough warm energy in the outdoor air to properly heat your home down to outdoor temperatures of around 35-40 degrees. Once it goes below that pointo your heat pump system will kick in its back up heat of a gas furnace or electric heat strips. You can think of the electric heat strips as really big hair dryers with coils that heat up and air flows over them to be heated. With the innovations being developed in today’s heat pump systems, you can see some really great energy savings. Besides geothermal, there isn’t a system more efficient than a standard heat pump system.

Air Handlers (Fan Coils)

Daikin Air Handler Product

Air handlers, also known as fan coils, are fairly simple in design and application. They are responsible for moving the air in your home through the return duct work to be heated or cooled and back into the living space through the supply duct work. An air handler consists of a blower wheel (made up industry name: squirrel cage) that moves the air throughout the home. It also houses the evaporator coil, which partners with refrigerant to remove or add the warm energy into the air stream. On a heat pump system that is all-electric, you will find a heat strip on the unit that consists of a series of coils that heat up via an electric charge to warm the air when temperatures drop to a level where the heat pump can not keep up. In the southern states, where they do not have extremely cold seasons, it is common to have a fan coil attached to an air conditioning unit. In the northern states, where we are located, that is very rarely seen as we have an extreme cold season.

Gas Furnaces

Gas furnaces are especially popular in Cincinnati and Northern Kentucky where prices for natural gas are extremely competitive, making it a very affordable energy source. They are a great way to heat your home during the cold winter months. The gas furnace heats your living space by bringing air through the return duct with a blower wheel. It then travels through the heat exchangers which allows the unit transfer heat from the burners into the air. It then goes through the non-functioning evaporative coil and into the supply duct work to return to the home. You probably have heard of the nasty carbon monoxide that is created during this process. These gases go from the sealed burner box, into sealed heat exchangers, and then exit your home through the exhaust vent pipe. If you hear of a cracked heat exchanger, that poses a safety risk to your family as that will allow the carbon monoxide to exit the heat exchanger and enter the air stream, taking it into your home. This is an extremely dangerous situation as it is an odorless and colorless deadly gas. If the parts per million in the air flow is significant enough, your furnace can be condemned. Please take this seriously to keep you and your family safe.

Small Packaged Units

Daikin Small Package Unit Product

Small packaged units are very popular in the Greater Cincinnati market. These are self-contained units that have both the heating and cooling source in the same casing. These are outdoor units that typically do not have the same higher efficiency options and typical split systems, but offer a convenient solution. Small packaged units come in air conditioning and heat pump models to give the consumer expanded options. You can also choose from two fuel options including electric only or gas & electric, depending on the fuel types available and their relative costs.

Geothermal Heat Pumps

We absolutely love geothermal heat pumps at Nelson Comfort! These are some of the most energy efficient heating and cooling options on the market. Geothermal systems utilize the Earth to transfer energy to and from the home, depending on the season. With a geothermal heat pump system, you will have horizontal or vertical loops installed in your yard, or even your pond if you have one that is accessible. The geothermal pipe is what will utilize the Earth’s energy to heat and cool your home. Another great feature about a geothermal system is that the entire system, except for the loop, is contained in your home, so you do not have to go out and clean your condenser coil before every summer. It will be difficult to find a more efficient system than a geothermal heat pump!

Oil Furnaces

Cincinnati's Oil Furnace Experts | Nelson Comfort

The basic operation of an oil furnace is similar to that of a gas furnace. It draws the air into the unit, heats up the air, and returns it throughout the home to keep the living space warm. Where they are different is the type of fuel they use and the way it is dispersed creating the heat. An oil furnace uses fuel oil. It is commonly kept in a tank outdoors and fed into the furnace. The fuel oil will then feed through an oil nozzle to the burner assembly. This is where it is introduced to a flame, causing it to ignite and start the heating process. Typically, oil furnaces do not operate at the same efficiencies as natural gas or LP, so they can be more costly in the long run but are great options for customers that do not have regular access to other fuel sources.


Boilers are still very common in certain parts of Cincinnati. People absolutely love the type of heat they experience from a boiler if their house is already piped for its use. Boilers take water and heat it up to a certain temperature. Once it reaches the set temperature point , the boiler distributes the water through the pipes in the house to radiate the heat in the living space. Once the water returns to the boiler, it is ready to be heated up again and sent on its journey throughout the house. The energy sources are wide in variety.

Ductless Mini Splits

Daikin Mini Splits Product

Ductless mini-splits are the fastest growing heating and cooling products in the United States. They been used forever internationally, where space is an issue, but are now being utilized more regularly in the United States. Ductless mini-splits offer a great solution for rooms or areas of the house that experience hot and cold spots depending on the time of year. These are also great for room additions and especially summer rooms that your current heating and cooling system may not be able to handle. If you are in the process of building a new home or replacing your current heating and cooling system, we would highly suggest looking into the ductless mini split options with their numerous features and benefits, including higher efficiencies.

Media Air Purifiers

Allergies are never fun to deal with, especially when there are solutions to help alleviate the issue. Indoor air quality is becoming more and more important to homeowners as they develop out their heating and cooling systems. Today’s media air purifiers are capable of capturing up to 99% of germs, pollen, and mold particles. This will help you and your family enjoy a better quality of life within your home. Whole home air purifiers, like those offered by Nelson Comfort, have the ability to clean up to 100 times more air than the common portable air purifiers you find at retail stores. You get all of the benefits mentioned above and we haven’t even talked about how it helps improve the performance and service life of your heating and cooling system!

Ultraviolet Air Purifiers

Platinum UV

Ultraviolet air purification, commonly referred to as UV, is gaining popularity in the heating and cooling industry. These units are conveniently installed within the duct work of your existing or new heating and cooling system. As the air passes by, the UV light scrubs the air to neutralize and kill particles. When matched with a carbon cell, like many of ours are, they have the ability to capture order-causing volatile organic compounds. As a result, you will experience clean, odor-free air being disbursed throughout your home. Now that’s what it can do for you; let’s talk about what it can do for your evaporator coil. Ultraviolet air purifiers are great at eliminating and preventing mold and other grime from growing on your evaporator coil, which is housed in a dark and damp coil box that is very inviting to mold and grime growth. After all, the air going into your home passes over the evaporator coil before being circulated back into the living space. These things are great!

Bypass, Fan Powered, & Steam Humidifiers

Do you experience static electricity in the winter, where you get shocked touching something as common as a door knob? Dry skin during the cold months? If so, there is no need to suffer any longer!  A ducted whole home humidifier is the perfect solution to the dry air causing these issues. Humidifiers from Nelson Comfort come in a variety of sizes and options. You have bypass humidifiers, which take the air from your heating and cooling system, humidifies it, and returns it back to the unit. There is also a fan powered humidifier that forces the humidity directly into the air flow to keep you and your family comfortable. We also offer steam humidifiers that heat up water, producing steam, and directly puts it into the air flowing back to your living space. Steam produces the most comfortable humidity since it transfers more water into the air. It is important to have a Comfort Consultant properly size the humidifier for your home to make sure it will make you as comfortable as possible. You want to make sure you have proper run times and humidity levels entering your home. No more dry itchy skin!
