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.
- Exhaust Fans
- Gas Furnace Installation
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.
- Geothermal Heat Pump Installation
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! These are some of the most energy efficient heating and cooling options on the market.
- Geothermal Installation
If you are looking for an environmentally friendly way to heat and cool your home, look no further — geothermal is the greenest option available! These systems use clean, natural energy to keep your home comfortable, with average efficiencies between 300 and 600 percent. Don’t just take our word for it, the facts on geothermal are very convincing: Using geothermal energy offers higher efficiencies and is more cost-effective than conventional heating and cooling systems, according to the U.S. National Renewable Energy Laboratory. The Environmental Protection Agency determined that geothermal is the most environmentally friendly option for home heating and cooling. Geothermal energy is natural, unending, and can be used anywhere. Geothermal systems are quiet, have a long service life, and require little maintenance.Geothermal systems use the constant, naturally-occurring warmth below ground as an energy source for heating your home. Geothermal systems provide both heating and cooling.

- Heat Pump Installation
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.

Access to reliable heating and cooling is essential in Cincinnati. To meet these comfort needs year-round, many homeowners turn to heat pumps, enjoying the superior efficiency and versatile solutions they provide.
