When I walked into my apartment for the first time in two weeks the indoor air quality told it all. I had left my younger sibling Kelsie to house-sit for me while I was away for work. When I left, the a/c in the family room was making some strange noises & I asked Kelsie to contact the home services corporation for A/C repair. I sent her the number of my favorite Heating, Ventilation, & A/C corporation & offered her a brief of all the observations I had made so that when the Heating, Ventilation, & A/C worker came, they would have an idea of what they were aiming to fix. I knew Kelsie likes to take things apart & then put them back so I unique ly asked her not to tamper with my Heating, Ventilation, & A/C device & to let the professionals do it instead. She enjoys researching random things & the heating & cooling industry has been no exception. She really knows more about my a/c than I do but I was still not confident with her YouTube-gained skills. She once fixed my control device however that was as far as I would go in allowing her to be my a/c worker. I did however let her check the air duct & seal any leaks she came across, then other than inspecting the air duct she could also replace the A/C filter, and being the smart cookie that she is, she called & told them that she wanted Heating, Ventilation, & A/C maintenance. She ensured that the Heating, Ventilation, & A/C professional who came checked the Heating, Ventilation, & A/C thoroughly & that by the time he left, everything was running smoothly. When I came back home I instantly felt the difference compared to how I had left the house. The servicing did a lot to help with indoor comfort.
