Tree down need more AC (by AllyM [NJ]) Posted on: Jun 7, 2021 5:58 PM

So a very old oak was dying from the center and I had to have it taken down two years ago. It shaded one side of the house on the second floor where the bedrooms are. It did not make a difference because the sun was in weaker Solar Minimum. But now it's not. We are getting into Solar Maximum again and it is 15 degrees above the normal early June temps. So tenant calls and he can't get the AC down to the 71 where it usually stays. It's 75. I go over. Everything is running and I can feel cooling going on but it's not overly comfortable there. I realized the absence of the tree is now making the sun heat the walls from early in the day right up to later afternoon. So this tenant has been with me for 20 Years. He has brain surgery issues, back surgery issues and kidney stone issues. He's having more stone surgery tomorrow. He has a fan and will use it.

But I called the AC company and I'm going to get a mini split, Daikon he said the name was, 9000 BTU. Sales guy is going to look at the layout on Wednesday. The ducts are in the attic and I don't know how well insulated they are. Way to warm to go up there now. Ninety in the shade. Does anyone have experience handling this kind of thing and what else can I do? Attic fan?

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, donít know how well that works though. --66.169.xxx.xxx

I have many rentals in the San Fernando Valley of Los Angeles California -- where it gets very hot!

To compensate for the extreme heat, there is not one (1) solution but several that work hand in hand together. Here are my results.

During the average hot day in my valley the outside temperature can reach around 95 degrees. The means in an uninsulated attic it can reach around 130 degrees. This attic heat radiates through the house ceilings heating the rooms causing the house temperature to elevate at least8 degrees.

So outside it's 95, in the attic it's 125 plus and this causes the inside of the home to rise from 80 to 88 degrees, a death sentence.

So I then put thick insulation into the attic AND install SEVERAL SOLAR ATTIC FANS. With the proper circulation (enough attic vents to suck in air from all sides) the attic in now kept to around 100-110 degrees. That's 20 degrees cooler in the attic. With the insulation, it keeps the attic heat from radiating down into the home/rental. Now without air conditioning, the house stays around 80 degrees on a 95 degree day.

Then kick on the air and it takes the interior from 80 down to 70 without any trouble.

Then I also have blown insulation install in the walls of the house, lowering the interior temp another few degrees... every little bit helps.

Solar attic fans (2) $500

Attic insulation $1500

INsulation blown into the walls and plugged $3,000

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

Wonderful suggestions! The tenants, Michael and Sarah have very thick room darkening curtains and I will encourage them to shut them.

Robert J., I think you reached me through the ether because I began to look this morning for a solar powered gable fan before I looked here. The roofer who put the new roof on last August can add it. I texted him this morning and he will stop by on the weekend.

I called the good heater/cooling people for a price on a small mini split but the price they want is over $4,000 without the electrical work and I am at a low cash level right now so I don't want to do that. I am going to look for a small window unit for them but they might not want that.

The outdoor AC equipment was checked and a new starter was put on one. I know that's not the name but it's the thing that is like a battery. The tech did NOT wash off the outside unit with a hose as others have in previous years. He checked the air handlers and water pumps and cleaned them and changed filters too. No gas was needed.

Robert Ontario. There is some insulation in the attic. It's not a stand up attic and there is an old air handler in there but I will get someone to blow in some insulation but not fill the whole thing. I was going to do that years ago but the operator wanted to fill the whole thing and that didn't sound right so I backed off. Ducts for floor 2 are all up there and there are round vents in the ceiling.

It is frigid in the hallway entrance area downstairs. Tenant thinks its from the first floor AC but there is an open stairway going up and I think a lot of their cold air is descending and filling up the stairwell. I would have to build some walls and a door to stop that I guess.

Does anyone know of a good quality 5K BTU window unit? I have bought those $100 ones for emergency but they don't work except for one year.

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

Yes, it has been rather miserably hot recently in the Delaware Valley! But expecting 71 degrees inside? We're happy with 77, and never expect our central air to do better than that on especially hot and humid days like these.

I'd encourage THEM to buy a window unit, but MY handyman installs it (so the condensate drains properly).

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

Definitely look at attic and window insulation on second floor before going the AC route. When I replaced my AC system, they also installed spray foam insulation in the attic rafters. It saved me enough to allow them to reduce the required tonnage when configuring the AC system.

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
