Prices are live retailer offers and change often; compare.ac may earn a commission on purchases, at no cost to you. Where one model number is sold as more than one listing, the row shows the cheapest and links the others.
Soleus Air Saddle units are lowered over the window sill so they straddle the wall, which Soleus says removes the need to drill into the window for support. The WS5 models heat with a heat pump, which Soleus says works less efficiently below 30°F.
