comment How can 12 V halogen downlights be much more efficient than 220 V ones?
You'll need to consider all the important attributes like beam angle, color temperature, MTBF, bulb material, gas type, gas pressure, etc. My guess is you'll find a compromise on one that explains the increase in efficiency over the other.

comment Is installing a packaged HVAC unit (PTAC) a realistic DIY project?
+1 for stating that you can do duct work at least as good as what is typically done by pros. Every pro-installed home forced air system I've examined closely has had major problems (duct that's too small, no fresh air, no means of balancing, fresh air ported through attic with exposed fiberglass insulation, air path that bypasses filter, etc). The real question should be "If I get a pro to install an HVAC system, how much of it should I expect to have to re-do myself?"

comment How do i resurface my concrete patio?
How deep is the spalling? If you resurface, you'll need to remove all the loose bits. Once you remove those, is there anything left?

comment How do i resurface my concrete patio?
I live in British Columbia on the water. I resurfaced my patio several years ago. I get rain, snow, freezing, and salt spray here all winter long. The resurfacing is holding up well -- certainly way better than patio tiles do. I don't think freezing is a fundamental problem for concrete resurfacing. Rather, bad product selection and application will result in failure whether or not it's subject to freezing temperatures. Freezing might accelerate the problem, but it's not the root cause.

+1 for stating that the framing probably won't safely support much weight.

comment Installing Coax & Cat6 in 2-Gang with Electrical?
No electrical inspector I've worked with allows a mix high and low voltage in a single gang box unless the device in the box needs both (eg. Some thermostats). I've also never seen a UL listed divider. That would be required to comply with most electrical code regulators' requirements. The safe route is to keep low voltage out of high voltage boxes. You generally don't even need a box for low voltage by code.

comment Blower fan speed selection
In North America it is rare that residential HVAC systems are rigorously designed. You shouldn't equate what is customarily installed and configured by HVAC technicians as being correct or optimal. Case in point: The dynamic range of motor speeds available in a typical residential furnace is too small to achieve the optimal speed for the full range of conditions. You'd need a variable frequency drive to achieve that (I've retrofitted these), but they are expensive so residential equipment generally just uses the crude relays-and-windings method of speed control.

comment How to attach metal knife rack to tile without ruining tile?
Exactly. Here's a 1/4" diameter example. Here's a 3/16" example. It's the only thing I use for drilling mounted tile. I've cracked tile with pointed bits; never with a hole saw.
