The people I was with and myself genuinely have been on our own for a few months. When the people I was with him myself genuinely rented our condo, we had no idea what multiple problems we would deal with overtime. We found a lot of issues that kept us from working together on some problems, and the people I was with and myself genuinely liked living all on our own. We tried our best to keep our condo clean and very nice, and the owner of our property was always happy with us being the renters. One afternoon last week, the people and myself genuinely came back to our condo after work and found out that our furnace was not asking well. There was genuinely no warm air coming from the multiple air vents around our condo, and the people I was with and myself were hard-pressed to feel any warmth from the furnace. It was genuinely a problematic issue, and we decided to contact the furnace supply warehouse. The people I was with and myself did not realize we were causing some problems with our air conditioner and furnace. The biggest issue was not changing the air filters, which was causing a lot less airflow for the system. When the people I was with him myself heard that it was our fault that the furnace was not working properly, we genuinely decided to set a reminder to change the air filters every multiple months. The last thing we wanted was to be more negligent towards our heating and cooling system.
