Could a well-appointed inspection reveal underlying issues that, if left unattended, might culminate in catastrophic failures? Are there specific indicators or symptoms that should prompt immediate attention from a professional? How do industry standards and recommendations align with homeowners’ experiences regarding furnace upkeep? These queries raise essential considerations for maintaining a dependable heating system and ensuring comfort in one’s living environment.
