This is a question we often hear from customers, and we want to address it here because it helps to explain what maintenance is and why it’s vital.
When you notice something wrong with your home heating system, whether a furnace, heat pump, or another type of heater, you should call a service professional. This is the right instinct! Attempting to handle repairs on your own rarely solves the problem. In the case of gas-powered heaters, it’s potentially hazardous (and may be illegal). However, what you want to call technicians for is repairs. You don’t want to schedule maintenance to “tune-up” the furnace and stop what’s wrong. That’s not what maintenance is for.
