Geothermal closed-loop heat pump vs. lightning

I live in central Oklahoma. My house was hit by lightning and we have hail damage.AC (among other things) is out.

The HVAC guy has experience with the geothermal system, installing, etc, but not with lightning strikes. They have already replaced two circuit boards...still not working.

Catastrophe insurance adjuster has experience with lightning, but not with geothermal heat pump system. His bottom line...can the unit be repaired or will it need to be replaced?

I just NEED coolness. Please help this very hot early 50's wife!!!

Any help is appreciated.

Geothermal nightmare

We truly hope you can help us. We had a geo-thermal closed loop system (into the river) put in and it went online March 2012. WaterFurnace Super DeHeater, 4 Multi-Aqua mini-splits (included for AC) and an air-handler (included for AC). 3200 sq ft home with baseboard and in-floor radiant heating. $34,000 and we have had nothing but problems.

I have a home with two stained walls

I have a home with two stained walls. One wall is on a corner to the house. The other is in a angle (upper) near the roof.
I'm sending some pictures so you can see the stain.
I have cleaned it up and it comes back again.

Insulating a concrete block house

I am looking at a renovation job that involves adding a second floor to an existing one-story house. The existing outside walls are 8" concrete block with stucco.

The homeowner wants to keep these walls intact since the stucco is in great shape and the windows are new.

In order to comply with the stretch energy code we may need to insulate these walls. Is there a viable way to insulate these walls without disturbing the exterior and/or causing moisture issues? I am in climate zone 5a - New England.

Thanks for your thoughts and suggestions.

I need roofing advice

I need advice on roofing. I live in death hot/humid zone 9. I am not working this summer and have to repair my roof on my 1600 sq ft. mobile home.

I will replace some rotted decking with 1/2" plywood, and install Grace self-adhesive underlayment.

I am recycling 4" thick Dow blue Styrofoam. They are 2 ft x 2 ft.

I'm not sure the best way to attach them. (?)

To protect the Dow Insulation from the elements, I was thinking of spray foam roof because of the low weight. (?)

If I have an R-35 above my roof deck, is it OK for me to have a NON-vented roof cavity ?

Refrigerator EMF?

My daughter just moved to a place where the refrigerator back is on the other side of a wall, and only about 4 to 5 feet from the foot of the bed. I think there is also a TV on that wall (behind which is the fridge)

1) Is that distance enough, EMF-wise?

2) Will having a TV (the new kind) mitigate or enhance the EMF from the back of the fridge?

3) Is there a device which can fix the EMF coming from the fridge, and where to place it if there is?

Moisture barrier versus air barrier underneath slab

I plan on building a house on a slab later this summer (northern Maine). I have been planning on installing a 6 or 10 mil poly air barrier underneath my slab (and above my rigid foam) which would extend upwards from the edges of the slab and seal to my polyethylene air barrier located at the inner wall of my double wall assembly. Does the poly under the slab effectively block moisture or am I better off installing a vapor/moisture barrier to avoid moisture transfer into the slab, but at the same time continuing my air barrier under the slab? Thanks.

How to seal a Bilco door to prevent heat loss and moist air transfer?

We have a standard exterior Bilco door that leads to semi-finished space in our basement. We are having trouble with cold air coming in during the winter months and damp air in the spring/summer months. How can we seal this Bilco door without creating condensation issues around the door and/or seal? The air is coming from the cracks at the door hinges and around the doors themselves. It appears that the Bilco casing unit is sealed properly to the concrete. Home Depot sells polycarbonate domes that cover the doors.

Difficult Crawlspace Access

I have a Vermont customer who has requested that the crawlspace below their kitchen be insulated to improve to reduce cold floors and general discomfort. My biggest issue is the clearance in the crawlspace between the soil and the floor joists. I've recommended 3" of closed cell foam to the crawlspace walls and rim joists/box sills. I would recommend poly across the dirt floor and up the walls first, but my issue is the clearance. It simply isn't feasible to properly layout poly along the floor as there is less than 1 foot of clearance in most areas.
