Both of us spent the entire Christmas holiday at my Grandfatherrents’ home. I remember having a conversation with my Grandfather about quality heating. Their current home was typically warm and cozy, so I engaged him in a discussion about the type of heating device they had. I never bothered about such things until I started living on my own. An electric gas furnace heated the lake house I currently live in. The building’s management took care of all matters related to the heating business. My Grandmother proudly said that they had a dual fuel proposal and never failed to call the heating supplier for a gas furnace/heater tune-up. On the other hand, I had yet to deal with any Heating, Ventilation & A/C supplier since I left home. My parents also joined the conversation. They also said that they had the latest from the homeowner solutions. Two years ago, the Heating, Ventilation & A/C professional installed a ductless Heating, Ventilation & A/C in their home. It enabled them to have a zoned system, my Grandfatherrents also had a zoned system, and they both claimed it was easily energy efficient. They also reduced the amount of energy used compared to their previous unit. On the other hand, my parents needed to reach out to an Heating, Ventilation & A/C worker twice a year for a heat pump service. The conversation went on and on until they found a more exciting topic which was me. Talking about heating devices and indoor comfort was way more interesting than grilling me about when I would settle down or at least introduce my partner to them. It was not high on my list and did not rest well with them.
