This comparison highlights that while higher MERV filters capture finer particles, they may restrict airflow if your system is not designed for them, so select a filter that balances air cleanliness with proper airflow for your equipment. Choosing the right filter and maintaining a replacement schedule will preserve blower motor health and steady heating performance.

What Are the Best Practices for Thermostat Care and Optimization?

Thermostat care and optimization improve comfort and reduce heating expenses by ensuring accurate control and sensible scheduling of runtime. Start with simple tasks: replace thermostat batteries annually, gently dust and clean the thermostat cover, and verify the device is mounted away from heat sources or direct sunlight that can skew temperature readings. Calibrate or test accuracy by comparing room temperature reading to a reliable thermometer and adjust settings or the offset as needed; consistent readings preserve comfort and avoid unnecessary runtime. For programmable and smart thermostats, set realistic schedules that lower setpoints overnight or during unoccupied hours to capture energy savings without sacrificing comfort, and use built-in recovery features to avoid short-cycling. Proper thermostat care ensures the system responds efficiently to demand and is a low-effort way to support overall heating system performance.

Careful thermostat management complements filter work and basic visual inspections that together form a practical DIY maintenance routine before engaging professional services.

What Does a Professional Heating System Tune-Up Include?

A professional heating system tune-up is a comprehensive inspection and adjustment procedure performed by trained HVAC technicians to optimize safety, efficiency, and reliability of furnaces, boilers, and heat pumps.
