Ever since I moved away from home, our parents have wanted to downsize. I was the last of the teenagers to fly the nest and head off to school, then growing up, we had a 5 dining room home, which was wonderful for 7 people. But, when our parents became empty-nesters, they found it too big. After some research, they found this amazing small community with lovely 3-dining room homes. Dad and Dad put the previous apartment on the market, and it didn’t take long to sell. They purchased a smaller apartment and have been residing there for the past year. Last month, I cellphoned them to catch up. Dad and dad were lamenting about the high energy bill. When they purchased the house, it came with a gas furnace and an air conditioner. It’s winter, so I know they need the gas furnace to keep the apartment warm. But dad said the previous month’s energy bill was too high. It was even higher than it was heating the previous 5 dining rooms home. Dad asked if there could be an issue with the gas furnace, and I wasn’t sure. The best they could do was contact an Heating, Ventilation, and A/C supplier in the section to seek the services of an Heating, Ventilation, and A/C specialist. Dad said he’d been thinking of that and decided to call the Heating, Ventilation, and A/C supplier the following afternoon. She booked an appointment, and the Heating, Ventilation, and A/C specialist arrived at the apartment after a few hours. She went through every inch of the gas furnace system and noticed several worn-out parts plus the gas furnace needed a tune-up. The Heating, Ventilation, and A/C specialist explained to our parents the importance of correct gas furnace repair. Doing so made it more energy-efficient and would bring down the energy bills.
