Just last month I was doing some deep house cleaning. I was doing the dusting, some repairs of small things around the house and cleaning a lot of dust, grime, dirt and pet dander from the corners of the walls. When I went up on the ladder to clean down the grates of our heating and air conditioner air ducts, I noticed that it was really dirty inside and out as well! This alerted me to the fact that I really need to have our entire HVAC ducts cleaned out, but that can get to be a bit high-priced, which is how and why this ended up happening. I have not had our HVAC duct cleaned in almost a year! So, after discovering this during my house cleaning, I made a decision to pick up the phone and call out to a local heating and cooling corporation to see how much it would cost to have one of their heating and cooling specialists come out to do the deep HVAC ductwork. The heating and cooling company was very helpful and friendly, the price was right, and I tied up for a certified heating and cooling specialist to come out to my house to do the first HVAC duct cleaning in all that time! They were pretty quick to get me the HVAC appointment, and the heating and cooling specialist was out to the house the very next day and our HVAC duct was finally cleaned. I will have to call the heating and cooling specialist more official to get this HVAC duct cleaning done monthly in future.
