I own a few vacation houses in an extremely popular mountain getaway town. The last more than one years I have had a terrible increase in our energy bills for all of our rentals. I just don’t understand if it is a problem with the Heating, Ventilation & A/C units or something else. So, I telephoned our local Heating, Ventilation & A/C provider who sets up all of our rentals plus asked him to send out workers to all of our rentals. I was almost due for our annual repair checks which were included in our HVAC maintenance agreement, so I wasn’t worried with any added expense. The complicated area of the entire assessment for our heating plus cooling units was that they found no discernible reason. So, why on earth are our shoppers using their Heating, Ventilation & A/C units so much more? The Heating, Ventilation & A/C worker was surprisingly forthright with his answer. He said that climate change is real plus the fluctuation of hot plus cold temperatures throughout the year are leading people to use their Heating, Ventilation & A/C systems beyond the boundaries of normal seasons. I was desperate for a solution to the financial increase, I didn’t want to have to increase our rental rates. He suggested installing the HVAC zone control Smart App on the all of the control units plus our cell cellphone. I could monitor the thermostat settings that way, but more crucially when people accidently leave the heating or cooling system running when they leave or are not in the rental, I could definitely turn the heater or a/c down or off. The renters never would be the wiser plus I would never adjust it when they are in the rental. I so much hope this helps our energy bills.
