Why The Right-Sized Furnace Is So Important

You need to make sure you choose a new HVAC system that is properly sized for your home. Sometimes people choose a system that is too small, thinking it will save money, but an improperly sized furnace will leave you with rooms that are always too hot, and others too cold- causing you years of misery. It will also wear out sooner, as it works harder trying to keep up with demand! Getting a furnace with the proper AFUE (annual fuel utilization efficiency)- kind of like Miles per gallon ratings, but for furnaces- and the properly sized blower fan- will help ensure you get the right system for your home.

In addition, when choosing a new system, you want to consider the improvements that may have been made over time. Often a home changes over time- basements or attics are finished, three-season rooms are added, or walls are changed- and all of these things can affect on how well your HVAC system works.

Before Your System is Installed

Cleaning Around Your Furnace Is Helpful For InstallationOnce you have chosen the new system, sized for your home, there may be some work to be done before installation day. First of all, you should make sure the area near the furnace is clean and vacuumed and no clutter is nearby. This will give the installers ample room to work when replacing your current system. It will also help eliminate any problems with getting dust and dirt inside your new system by accident!

Before your new system is installed, the HVAC technicians will check to make sure you have the ductwork you need, get prepared for any additional ductwork needed to make connections, and whether any electrical or gas lines need to be moved or relocated.

The technicians will also need to make a lot of measurements, to make sure your system will fit, they can move it in easily, and they can have everything they need for the day of the actual installation.

If you are switching from oil or gas to electric, additional work may need to be done to make sure everything is sized appropriately and ready to go on installation day.
