Ductless Mini-Split Install & Repair In Spokane & Spokane Valley | Mainstream

Are some rooms in your home too hot or too cold? It may be time to install an efficient ductless mini-split.

A ductless mini split is a type of AC system that doesn’t require ductwork to push cool or hot air. This makes it a great choice for historic homes or rooms where ductwork can’t be done. Instead, a sleek unit is added to your rooms of choice where you can change the temperature of each one as you please.

Ductless mini-splits are more efficient than standard central AC and can help you save money down the road. Only turn on the mini-split in each room that you need, instead of trying to heat or cool the entire house based on one system.

Mainstream Electric, Heating, Cooling, & Plumbing are experts at mini-split installation, maintenance, and repairs. Our technicians are happy to inspect your home and provide their recommendations for your AC system.

Very personable and patient!

Both technicians that came to our home were great! They were very personable, and very patient. My mother in-law has a hard time with her English, as it is her second language, but they were both very patient with her, and made sure she understood everything that needed to be done. On their customer service alone I would recommend this company. We live in an old 1980's trailer which made it hard to find parts needed to fix our heating system, but they did all the research they could to try and find the parts needed. I am so glad I decided to call Mainstream Electric and will continue to use their services in the future.
