Black out curtains may help. --73.120.xx.xxx

If there is the garbage fiber glass insulation in the attic then count on air pockets where heat is easily transferred. A shingle roof is considerably hotter in the warm months as asphalt absorbs heat. Too often the best solution is to insulate along with installing new windows with low argon gas and E glass that has lower heat transfer. On the roof rafters install vents so heat will go to the top of the roof where the heat should vent out of top vent. While the warmer weather has come early here where the next few days it is going to 29 degrees Celsius and above in the house where the metal roof is a lot cooler then shingles where over this year going to install more spray foam insulation along with vents in the roof rafters where eventually will be able to keep the attic at room temperature all year round. This year cut down four ash trees on the south side of house where the ash beetle started to destroy the top part of the ash trees. If a building was super insulated then there would no need for heating or cooling system as this is called a net zero building where solar panels would supply energy as the heat loss and heat gain is minimal. Now the average temperature records are being broken where normally it is not that warm in the early part of June. Next step is the level of insulation in the walls which is going to help as well. --99.236.xxx.xxx

Try to get the walls insulated to help keep the outdoor climate outdoors, stacking in the attic is good but sunshine warms up where it can. --76.188.xxx.xxx

Thank you for the help. I will get more insulation in the attic as soon as a human can go up there. Yes, the sun is hotter this year and it and the moon are pulling the jet stream into an odd shape allowing all the southern air to come all the way up to the north. Probably the partial solar eclipse at dawn on the 10th that we will see here, is evidence of that. The early heat was happening in the midwest a few years ago. My cousin in law lives outside of Cleveland and they had warm weather almost all year. --108.24.xx.xx

Does it help any to get some shade on the ac unit ? I would also have the freeon checked, maybe it's been low and gone unnoticed since the unit hasn't had to work so hard. --172.58.xx.xxx

Another option is Ikea has special black out curtains where most of the heat would not come into room. Ikea uses metric size curtains where if too long could have size reduced at clothing repair place. In the house have installed a double curtain system where the light is close to window and the dark further inside the room. I doubt the increase temperature is going to be a one year event where now ice bergs are no longer seen on the coast of Newfoundland where the green is going further north. Installing vent material in the rafters will direct more heat to the top of roof. Spray foam has the least heat transfer along with does not absorb water or mold. China built a lot of dirty coal fired electric generating power stations as the industry strategy is to produce power for the lowest cost but pollute the most. China says they will do something in 2050 which means absolutely nothing at all. --99.236.xxx.xxx

Solar screens on the windows, and I have heard of some paint that have a radiant barrier built in, don’t know how well that works though. --66.169.xxx.xxx

Have you serviced and cleaned the outside unit? Dirt, grass clippings and other things on the heat exchanger can reduce efficiency. --107.141.xx.xxx

A well insulated building uses less energy along the HVAC equipment is going last longer as the equipment is on less time during day or night. The weather conditions are not going to change where hotter summers are going to be the norm. Iceland will soon have no ice except during the winter months. --99.236.xxx.xxx

The walls in these 1950s homes are not insulated much but the wood over the uprights is not plywood. It is almost 2 inch thick boards so those have to have some insulating power. There is actually a gable fan but I can't find the switch. The guy who put up the cabinets may have buried in when he could not find a use for it. I remembered it this morning. The tenant is in the hospital today for a kidney stone but I will speak to him in a day or so and try to find the switch for the existing attic fan. There is a turbine on one end of the attic. The roofer wanted to cut in a peak vent but I said no because they make a house freezing cold in winter. --108.24.xx.xx

Still, if they are good tenants and the cash flow works, a minisplit is a good feature to have. --96.245.xx.xx

Spray foam is definitely better than radiant barrier. While radiant barrier lowers the temp of the attic, foam makes it almost the same temp as the living spaces, even on the hot 105 degree days. --108.69.xxx.xxx

Miss Ally, make sure you check to see if any of your local utility companies or a state agency are offering any deals on energy conservation. Around here they will do an energy audit for free & will do all sorts of insulation upgrades for free or a modest amount. --71.184.xxx.xx

Thank you. I will call PSEG for an energy audit. That's Public Service Electric and Gas. People keep saying spray foam in the attic rafters. You don't mean the wood under the roof right? Because that would trap moisture from the living space. You mean the attic floor right? Where insulation batts would go but I should get foam? Some foam years ago had chemicals in it that were banned and had to be ripped out. I am sure that has changed. I will check for the switch for attic fan that is existing. Tenant was in hospital yesterday so I will call later. Thank you so much. --108.24.xx.xx
