A friend of mine from work had invited me to his house for dinner one Friday evening. He had prepared fish fillets, potato wedges, and veggies. For dessert, we had chocolate ice cream with whipped cream. The meal was delicious and afterward, we gathered in the living room to chat over a glass of wine. It was winter and the winter cold was in full effect outside. The whole home heating within my friend’s house made me forget how miserable the weather outside was. This help with indoor comfort was provided by the dual-fuel heating available in the house. I noticed that my friend had a fireplace in the sitting area where we were in. I asked him how come his beautiful gas fireplace was not on, especially on a night like this. My friend told me that this unit had issues, it never came on even if they bypassed the programmable thermostat and used the power button. He explained how he had sought assistance from the HVAC professionals yet no one was able to resolve the issue. Now he relied solely on the hybrid heating unit. Since I was a trained HVAC contractor, I decided to check on the unit and discovered that one of the gas vents was blocked by foreign material. The HVAC techs had missed, anyways, I was not surprised since the heating device was a complex unit. Once I was done clearing the damage, the unit provided high-quality heating and cooling service. The bathroom at my friend’s house was fitted with heated floors that made the bathroom experience unforgettable. I have the ductless multi-split unit at my house and it does a good job in maintaining even temperatures throughout the house.
