This past Summer seemed to be absolutely off. It had seemed like my family and we were losing air conditioning from our residence absolutely quickly. It seemed like my family and we were losing air conditioning so quickly because my residence was feeling a little warm, usually my residence feels absolutely cool. We tend to like the air conditioning turned on absolutely low. Since it is turned on so low my house should believe cold. My residence was not feeling so cold. we could still believe the heat creeping in. We were not totally sure what was going on so we called my Heating, Ventilation & A/C supplier. We had also began seeing that my Heating, Ventilation & A/C plan was running a lot more. So when the Heating, Ventilation & A/C professionals came to my residence after we set up the appointment they checked out the system. The HVAC company said that the plan was working just fantastic & doing what it was supposed to. However since we were feeling some warmth within my residence the HVAC guy thought it could be the insulation. The HVAC guy had checked around the doors & the windows to see if there were any cracks. Had there been any cracks they would use a spray foam to seal these cracks. It is absolutely self-explanatory to use. You just spray it right on the cracks & it dries to seal the crack. However in my case the insulation inside my walls was deteriorating. The insulation was no longer there. My residence is so ancient that the insulation has kind of disappeared. So we were going to require to install more blown in insulation. This would take a long time & force me to put some holes in my walls.
