I’m very worried now

My husband plus I bought a truly attractive house about 2 years ago. It was absolutely our dream come true, plus both of us picked out the perfect property for the family. The two of us have sprawling oak trees out back, along with 3 acres of pasture land. The house is large and beautiful, and our kids have plenty of space to run around. After residing in the home for 4 years, I have noticed a lot of new issues with the indoor air conditions. Whenever both of us first moved in the house, I feel like the Heating, Ventilation, plus A/C unit worked great. The home was always cool plus crisp in every space in the warm season, even when the outdoor temperatures were humid and in the nineties. In the Winter months, then our venue was always hot plus cozy against the brutal outdoor chill. I never noticed much dust on the household surfaces until just recently, now it seems that the indoor air conditions is less than attractive. I decided it was time to give in and contact the local Heating, Ventilation, plus A/C contactor, plus have our entire heating and cooling system investigated for possible problems. The Heating, Ventilation, plus A/C provider came over, plus performed a careful inspection on our heating plus cooling system. They cautiously probed the electrical system plus the mechanical system, they also inspected the ventilation system plus our Heating, Ventilation, plus A/C ducting. That was when they finally discovered the source of our air quality issues. The main ducting system had developed numerous holes, plus there was 2 spots where the ducting was entirely clogged. I have noticed a immense difference in the air quality, and I hope this air duct service will continue to do the trick. It would be nice to have lower energy bills each month plus better air quality in our house.
