Why Isn’t My Heat Working?

Pennsylvania residents know that having a reliable furnace or boiler to heat their homes in the winter is essential. Have you been getting the dependable heat you need to stay comfortable and safe this year? If not, read below for some tips you can try before scheduling a repair.

The Dwyer Difference

As pleased as we are to maintain your heating and cooling equipment, we also care about saving you money. We don’t want you to have to make unnecessary service calls, which is why we’ve compiled a list of common troubleshooting tasks you can perform before you schedule your quality HVAC repair.

Read Your Oil Tank Gauge

Our customers heat their homes with gas or oil. While natural gas is distributed through underground pipelines, oil is delivered to your tank through a fill pipe located outside of your home. To check the level of oil you have left, look for the small glass cylinder on your tank. It will read like your car’s gas tank, divided into quarters. Typically, you should order oil every time your tank gets close to ¼ full, but sometimes an order is missed. An empty oil tank will definitely result in a lack of heat. To avoid the discomfort and danger of a no-heat situation, sign up for automatic delivery and never run out of oil again!

Check Your Thermostat

Several things should be checked on your thermostat. First, are the batteries dead? Second, is the furnace temperature set above the current room temperature? Finally, sometimes the cooling function can be accidentally switched on, which will prevent heat from blowing.

Reset the System

Sometimes a simple reset is what’s needed. There is a reset button on your heating system’s burner: press it ONCE ONLY, and listen for the system to restart.

Verify the Emergency Switch Is On and Breaker Is Sound

The emergency shutoff switch, usually next to your stairs or furnace, must be in the “on” position. Since they look like light switches, sometimes they get turned off. Afterward, check your breaker box for blown fuses or tripped circuit breakers.
