Heating, Cooling, & Air Quality Services in Spokane

Heating Services

Is your furnace not producing enough heat? Have you had your boiler for more than 15 years? No matter what your needs are, the HVAC technicians at Mainstream are prepared to repair or install any heating system.

Air Conditioning Services

Beat the Spokane heat with quality cooling services by Mainstream. So whether you are looking to install a new air conditioner or keep your current one running at max efficiency, we have your back.

Indoor Air Quality Services

Help make yours and your family’s health a priority with our indoor air quality services. Poor home air quality can aggravate allergies and affect your respiratory system. If any member of your household has asthma or is medically vulnerable, you should consider booking an indoor air quality assessment.

Allow our technicians to inspect your home for allergens, bacteria, and harmful pollutants in the air to recommend a personalized solution. We offer air purifiers, air filtration systems, and humidifiers and dehumidifiers.

If there’s one thing we all know about in Spokane, it’s that heating and air conditioning are a must!

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.

Great seasonal service!

Great seasonal service today on our furnace and air handler/AC unit. Matt Miller did a very courteous and professional job describing all that he was doing and did and made additional recommendations on future service and care. He was very knowledgeable and had great interpersonal skills. We have used Mainstream for other projects as well and have always been satisfied with the work performed. I can say with honesty that they have not always been the cheapest, but they have always been the best. 'Good service is not cheap and cheap service is not good.' If you ever need a plumber, electrician or HVAC specialist, I highly recommend Mainstream.

Knowledgeable, fast and efficient!

Norm and Adam were knowledgeable, fast and efficient when installing my new furnace. They had answers to all of my questions and explained everything they were doing. I would recommend Mainstream Electric to anyone needing help with their heating. They even assisted me in getting financing for my furnace. Thanks to everyone at Mainstream Electric you are great!
