Common signs include unusual noises, increased energy bills, water leaks, uneven heating, or the boiler frequently shutting down. If you notice any of these, you should schedule a service promptly.

A boiler service typically includes a thorough inspection of the system and cleaning components, testing safety controls, checking for leaks, and ensuring the boiler operates safely and efficiently.

It’s recommended to service a mini-split system at least once a year. However, for heavy usage, semi-annual maintenance (spring and fall) is ideal to ensure peak performance.

Mini-split systems are highly energy-efficient because they allow for zone-specific heating and cooling, which reduces energy waste. Look for systems with high SEER (seasonal energy efficiency ratio) ratings for optimal efficiency.

It’s recommended to service a geothermal system once a year. Regular maintenance ensures efficiency, detects potential issues early, and prolongs the system's lifespan.
