When our spouse and I purchased our up-to-date home, I was blissful by the individual thermostats installed into each room. Although the gas oil furnace and central a/c were obviously quite old, I knew we’d save a ton of money on our utility bills because of the zoned control. The two of us wouldn’t be paying to maintain empty rooms at the ideal temperature level. The two of us could target rooms that tended to get overheated or think cold without impacting the entire house. Plus, customized thermostat settings would allow us to cater to personal preferences. The two of us made sure to hire a licensed business to inspect the heating and cooling plan before we put in an offer on the house. The Heating, Ventilation & A/C worker confirmed that the plan was rather outdated however in fine shape. He said we could expect it to last at least a few more years. It was only after we moved in that we discovered the condo was not set up with zone control. Adjusting 1 thermostat affected the temperature throughout the whole house. All of the thermostats were linked. Because of the age of the heating and cooling equipment, it wasn’t compatible with the upgrade for zoned temperature control. While the oil furnace and a/c operated reliably, they definitely weren’t energy efficient. Our yearly heating and cooling bills were enormous. The two of us figured that it would cost us more to keep the oil furnace and a/c than to upgrade them. The two of us took out a beach condo improvement loan and had the whole plan torn out. The two of us then installed a high efficiency Heating, Ventilation & A/C unit with zoned control.
