Your furnace not only keeps your home comfortable and warm but also contributes to the indoor air quality as well. Many people are concerned with health and safety as well as energy efficiency when it comes to looking at a new furnace. There a few things to look for that will tell you when to replace your furnace including the age of your current unit, its performance, and your utility bills.
The furnace’s specifications should fit your needs. A furnace that’s too small won’t keep your house comfortable during extremely-cold weather.
Partly to avoid that possibility, the furnaces in most homes are larger than necessary. Initial cost is only one of the drawbacks of that strategy. A furnace that’s too large will cycle on and off more frequently. That puts more wear on its components, wastes energy, and might cause the temperature to vary uncomfortably. Also, a larger replacement furnace might require larger ducts. Without the right size ducts, airflow can be noisy.
There are a lot of resources available to help you find the right heating unit for your home, but the best route is to contact a professional who can assess your needs and recommend the right fix.
