Question

My heating system provides uneven heating, and my house ends up being cold. What can I do?


Answer

Older heating systems tend to provide just a short blast of heat before shutting off for a while. Consult with John Duffy Energy Services about getting a two-speed variable motor installed, which will provide you with more even and regular heating and a greater level of home comfort.

Question

What should I do if my heating system isn’t working?


Answer

John Duffy Energy Services is always happy to send a technician to help ensure that your system is functioning the way it’s supposed to. However, you might be able to save time and money by first checking a few basic things. Make sure the temperature switch on your thermostat is turned to “heat,” and set above room temperature. Check to make sure your tank has fuel, and check for any circuit breaks or blown fuses.

Question

What are the advantages of an oil-fired water heater?

An oil-fired water heater produces the hottest flame of any water heaters out there, which means your water heat up more quickly and efficiently. This, in turn, means you’ll save money and cut costs.
