This heater is not the size we want

I’ve been living in this house for the last 8 months; During the Wintertime, I used the little gas furnace in the house plus it worked perfectly to keep the air in the locale warm. I never had an issue with it. Once the weather started to go ahead and heat up, I turned on the air conditioner system using the little temperature control in the apartment, plus also didn’t have any awful troubles with it…until now. It’s currently over 95 degrees outside plus the Heating plus A/C component just went and stopped working. The blower pushes out air… but it’s super hot air. It’s love a fan instead of an cooling system plus our whole house is super hot. I am literally melting sitting in here. So, I turned the entire Heating plus A/C system off plus waited around for a couple minutes while I went out for groceries. When I finally got back, I turned the air conditioner system back on plus like magic, it worked perfectly. So, I thought everything was fine, but then the following afternoon once the un-even temperatures got up into the upper 80s, the air conditioner died right away again! I waited several minutes plus turned it back on plus it then worked just fine; 100% no problems with it for the rest of the afternoon plus zero in the night. Then of course the next afternoon the same thing happened. It’s really similar to if a fuse blows when un-even temperatures get over a particular point. Though I truly believe that’s not the issue. I tried calling a few Heating plus A/C workers, but they seem to all suppose I’m crazy. I am going to have to get to the bottom of this AC soon; otherwise I’ll have to idea to leave our house during the very hottest times of the afternoon.
