Frequently Asked Questions
What are the benefits of installing a whole-home air purification system?
Whole-home purifiers reduce allergens, dust, bacteria, viruses, and odors throughout your entire home—not just one room. They help relieve allergy symptoms, support respiratory health, and create a cleaner, more comfortable living environment for your family.
How often do whole-home air purification systems need maintenance?
Most systems need a check-up once or twice a year, typically during seasonal HVAC tune-ups. Mainstream inspects filters, electrical connections, and purifier performance to ensure your system keeps running efficiently and effectively.

How often should a commercial HVAC system be serviced?
We recommend servicing your commercial HVAC system at least twice a year—typically in spring and fall. Mainstream can customize a maintenance schedule based on your building’s size, usage, and system type to keep everything operating smoothly year-round.
What are the benefits of regular commercial HVAC maintenance?
Regular maintenance keeps your HVAC system running efficiently, reduces energy costs, prevents unexpected breakdowns, and extends the life of your equipment. Mainstream offers tailored maintenance plans that help Spokane Valley businesses avoid disruptions and stay ahead of costly repairs.
What are the benefits of upgrading to a programmable or smart thermostat?
Upgrading to a smart or programmable thermostat gives you better control over indoor temperatures, lowers energy bills, and allows remote adjustments from your phone. Mainstream makes installation easy—helping you get the most from your HVAC system year-round.
Are there special considerations when replacing a thermostat in an older home?
Older homes may have outdated wiring or non-standard configurations, but Mainstream’s technicians are experienced in troubleshooting and adapting solutions to ensure safe, reliable thermostat upgrades in any home.
