Some people have a absolutely enjoyable feeling after they get their home professionally cleaned, then as for me, although that is enjoyable & fine, I get a actually great feeling after I have the HVAC duct of our central heating & a/c idea cleaned! I have our HVAC duct cleaned 3 times a year, then most people do not have it done that often, although I do because I have a actually great Heating plus Air Conditioning repair program that gives myself and others a charming discount on all HVAC duct cleaning & other Heating plus Air Conditioning labor throughout the year.
After a enjoyable HVAC duct cleaning, when our central heating or a/c idea comes on (depending on the time of the year), it just blows out the most charming air quality without the use of a whole home whole-house air purifier, and that is how clean our HVAC duct is! I even had our indoor air conditions worked on a few times by an air quality professional repair here in our area, & they even commented on how our home has some of the best indoor air conditions they had ever seen! It actually boils down to having clean HVAC duct I guess; Central heating & a/cs that do not have their HVAC duct cleaned too often are usually the main cause of exhausting indoor air conditions.
This is what I was told by both our local heating & a/c company & the air quality experts that worked on our air quality; Ductwork cleaning is the key to a better quality of life. And it is also the key to top quality central heating & a/c!
