We recently installed an LG mini split air conditioning system on the second floor for homeowners with a boiler.
They were very particular about how it was going to 'look' from their patio on the ground and elected to have a curb built of wood so it can be sided or painted. It's hard to notice the cover over the piping on their siding and only if you look really (really) hard you might (maybe) see the pvc drain tube hugging the chimney. The guys did a fantastic job and the homeowners are very happy.
This system has high efficiency heat capabilities and very quiet air conditioning, allowing these homeowners a sound sleep, and they won't have to not turn their boiler on until possibly late November or even December.
Temperatures after installation reached 102 and it is cooling the entire house easily. If you live near Oshkosh and want to see if a mini split air conditioning system is right for you, call us ~ we have the 'Excellence' credentials given by LG as their preferred installers!
