Looking for advice on a few mini-split quotes from different brands: Panasonic, Carrier, Innovair

Hi all, and thank you for any advice or feedback on the following quotes :)


Context: I'm in my first home in Massachusetts built in 1890. The house has no existing cooling system and no ducts. It has an oil furnace with steam radiators for the primary heat source.

Goal: To install mini-splits for cooling, primarily, but we'll use the heating in Spring/Fall when the radiators feel like overkill and also use it in specific rooms in the Winter when we don't need the whole house warm.

Size: Five heads total. Four of them will be in smaller rooms (bedrooms, offices). One will be in a larger space that will cover the living room, dining room, kitchen (there are no doors here).


(A) Company 1 / Quote 1: Innovair - $24,000

  • 4x MHW09H2BHRB (9k BTU)
  • 1x MHW18H2BHRB (18k BTU)
  • 2x MOM27H2BM4B (27k BTU 4-zone outdoor condenser) [one would have 1x 9k + 1x 18k connected; other would have 3x 9k connected]
  • 10 year manufacturer warranty on parts; 1 year parts and labor warranty from company

This brand makes me the most nervous, but is naturally cheaper. Does anyone have any experience with Innovair?

(B) Company 1 / Quote 2: Panasonic - $32,000

  • 4x CS-XZ9AKUAW (9k BTU)
  • 1x CS-XZ18AKUAW (18k BTU)
  • 2x CU-4Z24BBUC (24k BTU 4-zone outdoor condenser) [one would have 1x 9k + 1x 18k connected; other would have 3x 9k connected]
  • 12 year manufacturer warranty on parts; 1 year parts and labor warranty from company

This brand makes me the least nervous, but is naturally the most expensive. We're intrigued by the NanoeX air filtration to help with air quality, allergies, etc., but I'm unsure if this is actually effective or snake oil. Any thoughts are appreciated!

(C) Company 2 / Quote 1: Carrier - $30,000

  • 3x 45MAHAQ09XA3 (9k BTU)
  • 1x 45MAHAQ06XA3 (6k BTU)
  • 1x 45MAHAQ18XA3 (18k BTU)
  • 1x 37MGHAQ48FA3 (48k BTU outdoor condenser) [all heads connected to single condenser]
  • 10 year manufacturer warranty on parts; 1 year parts and labor warranty from company

This feels like the in-between option.


Additional Notes:

Company 1 is newer to HVAC, but an established and trusted electrician.

Company 2 also offers Mitsubishi products, which seem to be the top of the line and I assume it would be ~25% more.


I'm curious to hear any immediate reactions to these quotes. My assumption is that Panasonic is the most trusted name, but please share any knowledge!

Thanks so much

Hi, we've discovered some carpenter ants on the perimeter and inside the front porch of our old home in Massachusetts and I want to act fast.

I'm seeing a mix of recommendations, with the top being Alpine WSG, but I can't seem to order that to my state. So I'm hoping to get the best advice given that restriction.

Products I'm seeing recommended:

Any others?

Thanks so much!
