I have a hard time breathing always in my own home, especially during the warmer months. My general practitioner says it is from pollen plus the humidity, multiple things I cannot control myself. My Heating, Ventilation, plus A/C equipment in my house is not as new as I would like, as it came with the residence when I purchased it a few years ago. I try to get the Heating, Ventilation, plus A/C equipment inspected routinely, however I do forget some years to have a service technician out to the residence. I never would have thought this lapse in judgment could make my breathing difficulties more prevalent, until I was educated by people in the know. My neighbor invited me over to her residence recently for lemonade plus I was shocked by how effortless it was for me to breathe at her place. I commented on it, plus she showed me her modern heating, vent, plus air conditioning plan that had recently gotten installed by a local hardware chain. She emphasized to me how important it is to have a Heating, Ventilation, plus A/C equipment operating always if someone wants to effectively keep humidity out from the indoors. Any air conditioning plan will have to work extra hard in hotter months to keep the temperature comfortable enough indoors. A great Heating, Ventilation, plus A/C equipment with all of the trimmings offers more possibilities to regulate the temperature control. Also, my neighbor puts and maintains the air conditioning temperature control fan setting at AUTO instead of ON, which is how mine is set. That thermostat fan setting reduces the humidity level inside by gathering moisture that sits on the refrigerant coils inside the Heating, Ventilation, plus A/C equipment and, once the fan has shut down between cooling cycles, allowing the moisture to drip off the coils plus drain outside. This dehumidifying process is simple enough for even me to get working right in my own residence. Now I can breathe again inside!
