  • How do outdoor mist-cooling A\C units fare in real-world usage?
    I installed the Cool-N-Save system on a 4-ton A C unit that was scheduled to be replaced in three months After that three month period in the middle of the summer, the positive effects of the system were negligible at best, and probably detrimental
  • Should I insulate air conditioner coolant pipes?
    Any cool pipe in a basement will benefit from condensation reduction through insulation Running a dehumidifier will also help I have mine piped with a cut-off hose right over to the floor drain, and then connected to a right angle barb fitted with a 1" piece of hose going into the drain Hot water pipes will also benefit
  • energy efficiency - Does keeping downstairs air off at night force the . . .
    Warm Air rises - even when you cool the lower floor - the warm air will rise There is a temperature coefficient for how hot your 1st floor ceiling is versus the temperature setting of the upper floor
  • Would insulating copper pipes keep the water cooler?
    During the eight hours I am at work and no water is running through the pipes to cool them down the water still gets scaldingly hot, but once you run cooler water through the pipes it takes much longer to heat back up again to scalding (now it takes around 4–5 hours to heat back up rather than an hour like before)
  • Can I use a timer to keep a refrigerator from freezing its contents?
    Realistically, you'd be lucky to save even $1 per month Not Cool As Much; A typical refrigerator should hold a temperature between 32 F and 40 F A wine cooler should be somewhere between 50 F and 59 F You might think you could turn a refrigerator into a low-budget wine cooler by running it only part of the time
  • How can I improve second floor HVAC performance?
    Setting the registers wide open downstairs and minimally open upstairs should achieve the opposite 1920s architecture probably intended for the bedrooms to run a bit cool in the winter since those were primarily for sleeping—and while under heavy blankets—not casually reading or playing video games
  • Better to run air conditioner fan on high or low speed?
    If you want the area as cool as possible, run both units at high fan A rule of thumb is 4 air changes per hour under normal humidity and 12,000 BTU (1 ton) per 500 sq ft If the unit is oversized, it will cool the space too quickly and cycle off before enough humidity is removed causing the walls to sweat
  • Does an air conditioners fan use more power on Max than on Auto?
    I have an inverter air conditioner unit I usually set it on 26°C, to save energy consumption I live in a really hot area (it's 34°C right now (~93°F), in the middle of the night) My questions is about the fan speed options I'm using it on AUTO, but it becomes kinda hot when it slows down, and I start sweating
