220V mini-split A/C wiring questions...
Comments (8)Well, lets see: a heat pump IS an A/C that can run in both 'directions'. You don't need extra electrical wiring for that (the heat) to work. It would be good to know if the unit requires both the neutral and the ground. It would also be nice to know how you connected it at the unit. Scenario 1: It requires two hots, neutral and ground. You connected two hots and neutral but no ground. It runs happily. But it is not a safe installation since the unit is not grounded. Scenario 2: It requires two hots, neutral and ground. You connected the two hots and ground but not the neutral. Then it would depend on whether the indoor unit uses a 120v blower. This probably would not work. but it might. Scenario 3: It requires two hots, neutral and ground. You connected the two hots and neutral. There is an internal jumper between neutral and ground. This is similar to how older 220v appliances used to be connected. It runs happily. IIRC, new code does not allow this type of installation (for appliances). The best long term solution will be to run the 14/3 from the box to the unit. Run it outside if necessary....See MoreHeat Quality from Mitsubishi Mini-Splits with Hyper Heat
Comments (12)I am thinking out loud a bit here but: you might consider a ceiling fan. In heating season, set to draw air up, at low speed (and possibly adjusting where the minisplits direct the warm air). The idea is cool air is drawn up, forcing warmer air down outside walls, and more consistent temperature throughout, including less feeling of radiant cool from cold surfaces. Can't say how much it would help in terms of comfort but I can say this for sure - would be a lot less expensive up-front cost and easily reversible if you don't like or can always just leave it. To me would be worth trying for a hundred or two bucks. A lot less than hydronic baseboard. (It won't directly lower heating costs but if you are uncomfortable at a given temperature, it's likely you're setting temperature point above what would be needed if more even throughout)...See Moremini split leaking?
Comments (22)That vent you see there is probably not a slim duct mini split, Nikki. There's a fire sprinkler head that is too close, it would never fit in that spot. Plus someone going to put one of these there with no access to work on it? Uh, No. In the words of someone infamous: It's a complete and utter disaster. Complete Disaster. ----- The worker to maintenance lead---- What do you mean the building is flooding? I was trying to work on this thingy ma bob and I bumped the sprinkler system and now it's flooding the high end hotel. meanwhile because there is a pressure loss in the sprinkler system pipe it triggers the fire department, turns on sprinkler pumps to pump even more water. I've seen this first hand where a sprinkler head just broke due to age spewing nasty stagnant water every where. It's beyond what you can even remotely imagine of a mess....See MoreSanyo mini split won’t turn on
Comments (28)6. Dont understand your comment about 3 more units. Your comment here: Who do you think installed the three sanyos i have? + we're in a thread talking about DIY + the cons of spending money on comfort. Led me to believe you installed them. Which essentially proves my psychic ability is no where near my working in person ability. I don't service all areas. From the extent of this conversation it doesn't sound like you live anywhere near me. (Katy, Texas area) 7. Who do you call for your a/c service because you are right.…..They all break down. Hope you get a good deal. This is what I do... me, myself and I. For me it's not about a fading "good deal". It's more in the lines of performance, efficiency and pay back by a reduction in utility bills. From the rental house side it's to have tenants not complaining and calling me complaining it's too hot here or too hot there. (we had record heat here last year with temps over 100F as early as May. Not a single complaint from my tenant about AC) I am in rental houses all summer long where "we're trying to profit from $200-500 a door debt burden" with an AC that has seen better days. (These are rental homes I don't own, other people own.) This isn't bragging, it's telling the story so you don't make something up in your head either. 8. I expect my a/c units to remain serviceable for as long as i need them. I am 75, college educated, retired military, retired civilian and expect to be around for at least 8-10 more years. My dad may have served around the time you did. He served in the Marines. I think his stint was in the neighborhood of 4 or 5 years, some time in the 50's if I am doing the math properly in my head. Thanks for your service. Yeah I expect the same out of my AC units as well. The government that makes the rules I have to follow has other ideas. By 2025 the R410a phase out will take hold. Prices will jump -- hard freeze on any new equipment. The new refrigerants have problems. Will be short lived because they don't hit the targets set by the Kigali Amendment to the Montreal Protocol that was signed by then President B. Obama. Given what I see are true and honest facts / how equipment & refrigerant phase outs work due to banned refrigerants --- the costs will only continue to go up. They've already gone up by a wide margin thanks to guess who? (The inflation is only transitory crew -- let's keep spending) I doubt these Sanyo units of yours will make another 8-10 years. If I make it that far I will likely replace all mine at the ripe age of 70 with the realization I may need repairs as soon as 3-5 years later as this is the current cycle we are on. You'll never eliminate the need for service & repairs, that clock starts the day you put the new equipment in. I was just at a house yesterday that got a so called good deal put in by someone else. They can't find that guy... they called another company before me and they wanted to replace the whole system because they don't work on so and so brands. I go out there and replace a switch on the condenser and she's running again. The unit was only about 7 years old....See MoreDavidR
