5 Considerations Before Purchasing a New Furnace

Before you purchase a new HVAC system, give careful thought to these five items.

Whether you just got the bad news that your home’s furnace is beyond repair or it is just time for an upgrade, investing in a new home heating system is a massive and expensive undertaking. Make sure that you have a reliable St. Louis HVAC company to help you, and before making any decisions, take the following under consideration.

The Size of Your Home

Knowing the dimensions of your home is critical in choosing your new furnace. This includes the length and width of each room as well as the height of the ceiling. Do not take it for granted that you can install a new furnace that is the same size as your old one. Additions and changes to your home will make a difference in the type of furnace you need. Also, as your HVAC technician will tell you, going bigger is not better in this case. A furnace that is too big for your home will cause you to waste energy in order to keep it running.

The Size of the Furnace Space

Your new furnace should be able to fit perfectly in the space that the old one occupies. Have your local St. Louis HVAC company work with you to make sure that not only is it sized right but that the fittings are in the right places to make installation as easy as possible.

Efficiency Rating

STAR ratings are invaluable in helping you choose appliances that offer you the best energy efficiency. This is vital with a home heating system, which is typically responsible for almost half of your monthly utility costs. Purchasing a new home heating system is a huge expense; make it a worthwhile one by choosing a furnace that is going to help you save money each month.


A new furnace is one of the biggest single expenditures a homeowner can make. Ask your local HVAC company for suggestions on where to shop and any special discounts that they may have access to. If you are making a considerable difference in the overall efficiency of your home, the purchase may also count towards a tax credit for your income tax return.


Winter is almost here already, and you don’t want to be stuck for even one day with no heat once it does. Talk with the HVAC company about the installation process, its cost, and length of time. Try to work it out to have it done when no one is home in order for there to be little inconvenience to your family.

This is a good time to talk with the HVAC technician about zoning systems, digital thermostats, and whole-house dehumidifiers. These are all options that can be added to your heating system that will not only create a more comfortable environment but also make the home heating system more efficient. You are about to commit to a major improvement to your home.
