indoor air and the pollen levels

Both of us have had a mystery that we have been trying to solve for the past couple of weeks.  It seems that our occupants have developed pollen irritations ever since we installed our modern Heating, Ventilation as well as A/C system.  Both of us own a several equipment apartment downtown plus rent out the upstairs. When we first purchased the house, we decided to upgrade the Heating, Ventilation as well as A/C units in both our area plus the rental unit. Both of us really thought it would be a benefit to our occupants because it would save them cash on their utility bills.  Instead, they have been coughing plus sneezing ever since the replacement. Both of us installed several modern oil heating systems that are more efficient plus more powerful than the old units. They are supposed to deliver a more steady stream of heated air on a more consistent basis. Now, although the units are warmer plus more evenly heated, the occupants are constantly sick.   Both of us had no other option but to contact the Heating, Ventilation as well as A/C business that did the replacement to find out what the cause may be. He looked over the records plus asked why we hadn’t had the air duct cleaned at the time of the replacement. Both of us said that we had no way of knowing that it needed to be done. He said that the more powerful blowers were really stirring up dust plus debris that could contain mold spores plus bacteria. This was more than likely causing the illnesses for our occupants as the bulk of the dust would be blown upstairs. Both of us felt just disappointing that what was intended as an upgrade was clearly causing them complications.   Both of us arranged for the cleaning within the following month plus hope that it solves the complications.
