I need to speak to someone who is knowledgeable about

I need to speak to someone who is knowledgeable about inverter versus non inverter air conditioners, and in particular, the effect of frequent power outages on an inverter air conditioner, and whether an inverter air conditioner will have issues in a hot salty Caribbean climate, such that I am better off with a non inverter 2 stage air conditioner.

I have a Mitsubishi split system air conditioner with a wall

I have a Mitsubishi split system air conditioner with a wall mounted unit and an external unit. Fans are spinning in both, but there is no cooling action (incoming air is the same temperature as outside). This is the first time turning on since last season. Is there any trouble-shooting I can do of the sealed unit outside (no visible controls); or does this require (as I suspect) a support call to have a technician come and inspect?JA: Did you double-check the thermostat's settings? And what about the filters?Customer: The thermostat (on the remote) is set for 18 degrees, with the internal temperature is well into the 20s. I have not yet checked filters -- I assume these are all in the internal unit, with no user-accessible filters on the external unit?JA: Do you plan on doing the work yourself?Customer: Only if this is safe, simple, and feasible.JA: Anything else we should know to help you best?Customer: What's the phone number for air conditioner service/support?

I want to install a window air conditioner in a

Hi, I want to install a window air conditioner in a through-the-wall application using a sleeve. The wall is a wood frame construction.I know I can…. But I don't want to simply wedge the unit tightly between the studs and add a few screws because it's difficult to remove for cleaning and service.I want to know if the following is an appropriate application for my air conditioner, which is 19 9/16” W x 12 3/8” H x 19 3/8” D.LG 26 In. Wall Sleeve and Stamped Aluminum Rear Grille for Through-the-Wall Air Conditioners - AXSVA4I don't want to have to tear up the wall ever time I want to remove the unit. My goal is an installation where I can remove the unit periodically for thorough cleaning, maintenance, or replacement.

I had a zoned heat & air heat pump installed in my house.

I had a zoned heat & air heat pump installed in my house. One thermostat is upstairs, the other is downstairs. There is only one return in the house in the bedroom upstairs so that I can't shut off the area. The upstairs bedroom & bath are not used unless I have company. I am having a problem regulating the heat so that the downstairs is comfortable. At what temperatures should I set my thermostats? When I set the upstairs thermostat lower than the downstairs thermostat, the downstairs stays cold. Right now I have both set on 70; however, downstairs is still not warm enough. I am trying to stay comfortable without running up my bill.I saw your post where you said a thermostat should be set at 78. Is that the case in my house. 78 seems awfully high.

Installed Honeywell wi-fi thermostat. It will not turn on

I installed a Honeywell touch screen Wi-Fi programmable thermostat and it will not turn on. What could I have done wrong? Home is only 10 years old. Old thermostat did not have common (blue) wire connected but one was in the wiring. I replaced the thermostat and connected the blue wire to common and the other accordingly. Turned breaker back on but did not power up.
