Question about DUCTLESS mini split Air conditioners: Our

Question about DUCTLESS mini split Air conditioners:Our central air conditioner gave out after 15 years(diagnostic done by an hvac professional). I wasn't sure how much longer we'd be in the home, so I never got estimates on a replacement system, plus it's unaffordable at the moment. We are managing with window A.C.'s , a portable standing a.c., fans etc. On eBay, I came across 2 cooling methods that I'm completely unfamiliar with:Ductless mini spilt a.c./heat pump (this one by Mitsubishi). The other is on "Wayfair" it looks like the ductless, but it's just called "Seville Aura 12,000 but air conditioner with remote." What are these? How are they installed? Are the reasonable compared to a new central a.c. system?

I have a heat pump/ac unit, and an oil burning furnace, have

hi, i have a Bryant heat pump/ac unit, and an oil burning furnace, have had it couple years worked fine. couple days ago we briefly lost power. when i put regular electric back on, both heat pump (blowing air) and furnace are running. outside temp is 26F degrees so i don't think heat pump should be running. i tried advanced setting change to furnace only, but heat pump continued to run. What do you recommend? should i do a reset somehow?

I have a Weil McLain GO3 oil boiler with a Aquasmart 7600

I have a Weil McLain GO3 oil boiler with a Aquasmart 7600 controller set up to economize fuel as much as possible. The high limit is 180 and low is 140 F. The hight and low differentials are those that the unit came preconfigured. It takes several minutesto get hot water. Are there any changes to the settings I can make to improve this situation?
