Winter means freezing cold temperatures on a daily basis, which means that your HVAC system is going to be put to the test for months on end. When trouble occurs, you can’t waste a moment of time getting it addressed. Your home’s temperature can drop precipitously and present a health issue as well as a comfort issue.
However, while waiting on a heating problem isn’t an option, you should always take a moment to make sure that a heating repair service is required. Laymen should never attempt to diagnose a problem with their heater: they contain delicate components (and possibly dangerous ones such as gas lines) and require formal training and licensing to address.
