My little pup has the nasty habit of going underneath our house. When he first started it, I didn’t guess anything of it! It gets sizzling hot out after all without A/C so he was just trying to get into the shade… But after that I realized he was starting to cause havoc on the Heating & Air Conditioning plan by doing this, then this is because I live in a trailer and he managed to split into the section of HVAC duct connecting the intake vent indoors to the large Heating & Air Conditioning device outside. In fact, I figured this out one day when I heard a odd noise coming from the large heating and air conditioning unit in the corner of my study room. I walked over to look inside in addition to lo in addition to behold, I saw my dog inside of my Heating & Air Conditioning system! I took off the grill covering the heating and cooling air duct entrance in addition to was honestly able to pull my dog up into my home through it; As you can imagine, this was not great for my HVAC system, however heating & Air Conditioning units weren’t exactly built to have dogs inside of them after all! The cooling function seemed to drop after this with the plan not being able to keep my home as cool as it once had. I had to call an Heating & Air Conditioning business to send out a repairman to repair the damaged my dog had caused, which wasn’t cheap, in addition to then had to pay even more on an effective border around my home to keep my dog from going back underneath the trailer, then on the bright side, despite him not having underneath the trailer for shade someplace, he can be comforted by the cooling a/c with myself and others inside again now that it’s back in entirely working order!
