Ductless HVAC Options for a Home or Business
Believe it or not one of the most devastating aspects of any commercial or residential HVAC system isn’t the compressor, condenser, blower motor, or any of the other moving parts; it’s the thing that does supposedly nothing – the duct system. Duct systems not only carry allergens, dander, and debris to every room in the house, they are also a huge reason for energy loss simply in the transfer of air, let alone leaks.
It’s not hard to see why many homes and businesses are weighing their options for a ductless HVAC system. Eliminating the path of heated or cooled air from where it is handled to where it is delivered produces fewer allergens while also reducing energy loss. With that said, here are some of the ductless HVAC options available for homes and businesses, whether they are building new or replacing existing components.
Ductless Mini Split
The ductless mini split air conditioners are a trendy choice for both homes and businesses for a number of reasons. First of all, the lack of ducts helps lessen energy loss and creates fewer allergens jostling around the room. Ductless systems contain a compressor/condenser outside the home and copper lines carrying refrigerant to an indoor fan unit. This one-to-one setup proves ideal for cooling home renovation additions without trying to tap into the existing HVAC system or for use in a room that is unreasonably warm (facing the sun) without taxing the entire central air conditioner. With the installation of a heat pump, any ductless A/C systems will also supply warmth, serving as a full HVAC unit.
Single zone ductless systems are available in the most basic form for something like a lake house or rarely occupied room. They are also manufactured in more advanced versions that feature programming, motion sensing, wi-fi automation, and 3D airflow.
Multi-Zone Ductless Split
One hindrance of the single zone system is that the compressor can only cool one fan/vent component and therefore only one room. The easy solution is a more powerful multi-zone ductless system in which 2-4 ‘heads’ can be installed in different zones of the home or business. This proves a more cost-effective solution than running central air in a smaller square-footage home or a part-time residency. Multi-zone units also work great in a small office where multiple rooms may all want to have different temperatures (conference room, cubicles, break rooms, etc.).
Dual Condenser Units
For the most part, the maximum output that any single condenser can supply heating / cooling to is four rooms (or four fan / head units). The solution in larger homes or offices then is to install a second outdoor condenser/compressor unit which increases the output to between 6-8 different rooms. The configuration can be manipulated to the property owners needs whether they want a single control, multi-controls, or have heating and cooling in specified zones.
Another benefit of ductless systems is that the indoor fan units feature multiple mounting options. The fans can be placed on a wall, on the ceiling, recessed in either the wall or ceiling, or with concealed ducts. The temperatures can be controlled with a remote control and rooms are conveniently cooled without having to block the view with a window A/C unit or lose energy through a ducted system.
It should be noted that the split systems are not the only ductless HVAC options for homes and businesses. In fact, radiant heating in flooring provides perhaps the most comfortable room conditions of any HVAC system. With this installation, tubes run throughout a floor and are heated via water or electricity. This heat rises radiantly and warms objects instead of air, with a more even balance, and without ducts. The same principle works for cooling, forcing cold water through the tubes instead of warm. Radiant HVAC is definitely worth a look, especially if the home or commercial building is being built new.
The great thing about these various HVAC systems is that they provide options. Commercial or residential customers are not limited to a ducted air flow system and can instead choose heating and cooling options based on their home layout, health history, budget, and intended use.
