Choosing the right AC and/ or Furnace for your home
Proper sizing is the most important thing in replacing a furnace. Bigger isn’t better. Smaller isn’t cheaper. The best comfort and efficiency is through a properly sized furnace. If the furnace is too small it won’t keep the house at the desired temperature when it is cold outside. If the furnace is too big it heats the house too quickly and then shuts off. This results in hot and cold swings in temperature in the house.
