Our 20 year old Venmar air exchange machine broke
We have a central HEPA system and Need a new air exchange machine. Venmar won't help me. Our home is in the south humid, I'm not well, the Venmar was installed in the condition crawl space. Our home is 1800 square feet. I was told you need an air exchange machine for the HEPA to help. Please let me know what to get in Virginia?
You weren't able to get any support from Venmar? You can purchase HEPA air filters online but you would need to know the make and model of the machine. I would suggest you contact a local HVAC company to come and see if the machine can be repaired, and if not you may need to purchas a new one.
Air exchangers (and their filters) are important not just to remove airborne particles or aerosols such as Covid droplets) to protect the quality of air for occupants, they also remove moisture from the air. That means more efficient heating and cooling, better home durability and they prevent mold from forming.
