Any of you home improvement type people

Any of you home improvement type people have opinions on a multi-head mini split heat pump vs forced air for a <1k sq.ft. home?

comments in ascending chronological order (reverse):

The mini pumps are very popular; they tend to be reliable, and don't take extra cubic footage for air ducts. What sort of price difference are you seeing?

We've been quoted $10-12k for forced air in our house. A 4 head mini-split is $2.5k (Gree) to $4.5k (Mitsubishi), plus hoses and installation. And the Gree actually looks like the nicest unit.

I'm not quite sure how to coordinate charging the lines, but it's gotta be less to vacuum and charge lines than $5.5k+, right? Hell, I could buy the vacuum pump and get certified for that price.

I won't say it on Facebook, but getting certified is only important if you get caught doing HVAC/Refer work elsewhere, and for the warranty. I went whole hog, bought a new vacuum pump. freon (R410a) and a good gauge set. Option B that is popular is to put the whole system in, and pay a professional a service call to pull vacuum, check everything and turn it on. Seems $500 is a going rate.

$500 seems like about what the cost of the pump and such is, and since I'm unlikely to do it twice, seems like a totally reasonable price. Need to find a vendor to do the line charging, then.

Yeah. my math was different because I have a lot of units I could maintain with the right tools, and plan on some future upgrades. The "pay a vendor to do the test and charge" also makes your warranty valid. You do the grunt work, electrical, etc..

I got one of the Pioneer units completely hooked up and running today. Followed the good directions well, pulled vacuum for 30 minutes, monitored for 15. Pressure tested. etc.. all went perfectly. Turned power on. It had about a 10 minute delay for some reason (mentioned it in manual as well) and then heat came on. Nice warm gentle heat, with good airflow. Completely freakingly silent. all you hear is the air moving. Even the outside unit is very quiet. Next to the traditional units also on the building with noisy compressors, this thing is amazing. If it lasts a few years (and it looks like it should), this is a clear winner.
