"I am so very pleased with the service I received from Dependable Energy. I called Dependable in December when we noticed it staying cool in the house. We thought the furnace was broken since we did not hear it kick on. Dependable sent a service tech out and discovered it was a broken thermostat and it was replaced in a half hour.  We could feel the difference pretty quickly. And now that our heating system is working properly,  we believe the thermostat was broken since last winter! Thank you Dependable Energy for our new found warmth!!!"

"I have been a propane and HVAC air installation/service customer for about a year and a half and am consistently satisfied with Dependable.  Their staff are friendly and knowledgeable and I have never had a concern with them being in or around my home even if I'm not there.  They generally have responded timely even in busy periods such as the dead of winter and after storms. I know there have been instances where another company might have tried to upcharge me for equipment or services I don't need, but I feel Dependable has always been honest with me regarding what we need."
