HVAC Services Spokane WA | Call Key Tech Mechanical

For most Spokane homes, we recommend checking your air filter every month and replacing it every 1-3 months, especially during peak heating and cooling seasons. Our dusty springs and summers can clog filters faster, reducing airflow, straining your system, and impacting indoor air quality. A clean filter is a simple way to improve efficiency and prevent costly repairs.

This is a common issue here. It could be incorrect calibration, aging components, or a wiring problem. First, check that it's set to 'heat' or 'cool' correctly. If problems persist, our technicians can diagnose whether it needs recalibration, repair, or an upgrade to a more reliable programmable or smart thermostat better suited for our temperature swings.

Our preventative maintenance service is designed for local systems. We thoroughly clean components, check refrigerant levels, inspect electrical connections, test safety controls, calibrate your thermostat, and clean or replace the air filter. This proactive check-up helps catch small issues before they become major breakdowns, ensuring your system runs reliably and efficiently year-round.
