The unit had to work harder to keep up with the change in temperature hence the high energy bill
My partner and I have been together for 5 years. For 4 of those years, we lived in a 2 bedroom apartment in the city. We are city folk and loved living in an area near our favorite hangout spots. The coffee shop was only a block away and so were the bars and fitness center. But, eventually we had to find a house since we wanted to start a family. Our realtor found us a gem outside of town and the area has really grown on us in the last year. The house was a new build and had a brand new HVAC system so we didn’t have to spend any money on HVAC installation. All we needed to do was hire the HVAC company for maintenance in spring and fall. During our first summer in our new home, we noticed we were paying too much money to keep the house cool. At first, we weren’t sure why this was happening. We thought perhaps the HVAC system had an issue so we hired an HVAC expert to take a look. Her company does same-day response so a few hours later she passed by the house. There was no issue with the HVAC system. But, upon further investigation, the HVAC expert said by turning down the thermostat each time we felt hot, we were using more energy. The unit had to work harder to keep up with the change in temperature hence the high energy bill. It’s better and cheaper to set the thermostat at a constant temperature and leave it at that.
