There is nothing as stressful as being a new homeowner. If you have never been the person solely responsible for keeping up with a home & all of the service that it entails, let me tell you that it is very stressful. There is a steep learning curve as a new household owner. You hastily have to know all about insulation, indoor appliances, ventilation, yard upkeep, & so much more. I personally never had a crash course in heating, cooling, & air quality control equipment before I own my own air quality control system. Suddenly, it was up to me to understand how the furnace & air conditioning worked in tandem with my expensive smart control unit. I needed to have some basic comprehension of air air duct & circulation thermodynamics. I also needed to understand air purification devices & air quality for the first time in my life. This is what I found myself routinely calling the local heating, cooling, & air quality control dealership for their professional opinions on my many indoor air quality questions. After several months of talking about indoor air handling solutions with the reputable heating, cooling, & air quality control service shop, I was nearly ready to pull the trigger on my brand new indoor air handling set up. I finally had enough currency for all of the Heating & Air Conditioning equipment & I could get the time off of toil for the Heating & Air Conditioning installation. And then… My roof caved in. Who could have known, you mean to pay as much attention to your household infrastructure as your household indoor air. Now I have to choose – new roof or new Heating & Air Conditioning.
