The trick is locating the stale air intake and fresh air output ducts in such a way that they cause air to circulate throughout the house.
													
																	Air exchanger installation guide. 
								
	
		
	
																	If you have an hrv or an erv you have to clean the core. 
																	Air exchanger are installed in most new homes today they work with the existing hvac system to ensure fresh air is coming into the home. 
																	One way to minimize air quality and moisture problems in a home without opening a window is by the installation of a mechanical ventilation system such as an air to air heat exchanger. 
																	The intention of any hrv whether it is a ductless hrv like the lunos or has a centralized core is to recover heat before it is. 
															
													
								
	
		
	
																	You should check with your local code or the forced air system s manufacturer. 
																	Or just a standard fan or two that blow in opposite directions. 
																	If you can install the stale air intake on one level and the fresh air output on another level then a ductless hrv installation works perfectly. 
																	Picking the best system would be best done with the help of an hvac specialist i think. 
															
													
								
	
		
	
																	Caution the hrv and forced air system must be in continuous mode to achieve maximum comfort and to avoid cross contamination. 
																	Using a lunos ductless air exchanger or productair ductless ervs to circulate air between 2 floors in a home would be a lot of money spent for nothing i think. 
																	In this section you will find installation manuals technical data sheets and product brochures for venmar products. 
																	Check the manufacturer s instructions and oil as often as recommended. 
															
													
								
	
		
	
																	At the core of the air exchange there are small passage ways where the air gets warmed up with the stale air from inside the home. 
																	Some air exchanger motors require additional oil over their lifespan. 
																	Clean air exchanger core. 
																	Supply air from hrv or erv must be at least 3 feet from the forced air system. 
															
													
								
	
		
	
																	In both instances you have to remove the core from the system. 
																	Have you considered a ceiling fan. 
																	An air to air heat exchanger brings two air streams of different temperatures into thermal contact transferring heat from the exhausting inside air to. 
																	Can be different from a region to another.
