I should have done a lot more research when it was time to update the gas oil furnace in our home, unfortunately, the heating proposal quit in the middle of December, when the outside temperature was down to twenty-six degrees. There was no way our family could go without heat. I was in a hurry to either get the oil furnace repaired or install a current one, then since the original oil furnace was over twenty years old & had been threatening to fail for a very long time, I decided it wasn’t worth fixing. With the rush to get a current oil furnace installed, there was no opportunity to look into makes & models, read reviews for the many options or order something that would take awhile to arrive. I needed to accept whatever the local Heating, Ventilation & A/C contractor had available. I assumed the supplier would advocate a quality oil furnace & properly size & install it. They definitely sold me the cheapest model on the market & simply picked a oil furnace of the exact same size as the old one! Over the last twenty years, I’ve made a lot of improvements to our home. I’ve added insulation to the walls, ceilings & attic. I’ve updated all of the windows with thermal pane, Energy Star rated alternatives. I’ve made it a point to carefully weatherstrip, caulk & seal up every crack & leak which might allow energy to escape, my efforts have significantly reduced the heat gain/heat loss of the home. The Heating, Ventilation & A/C contractor should have done calculations & installed a much smaller oil furnace. Instead, I paid more for a big oil furnace that heats up the condo so suddenly, it never achieves maximum efficiency levels.
