Gelinas HVAC: Your Source for Plumbing, HVAC, and Electrical Services
Tankless water heaters heat water through narrow heat exchanger channels that are particularly vulnerable to hard water mineral scale. In Scarborough homes with private well water, scale accumulation causes reduced water flow, fluctuating water temperatures, and recurring system error codes. Routine descaling cleans internal passages and protects the heat exchanger from costly mineral damage. Gelinas HVAC Services services all major tankless brands, holding active Maine trade licenses, full insurance, and an A+ Better Business Bureau rating. Call (207) 672-2801 and note any displayed error codes when booking service.
