Annual Fuel Utilization Efficiency (AFUE) measures how well your furnace turns fuel into heat. It’s similar to MPG in your vehicle, but for furnace gas usage. The higher a furnace’s AFUE, the more heat you’ll get per dollar spent in fuel.
In most cases we can help you move your furnace. However, it depends on access to gas lines, venting, and code requirements. We’re happy to provide an assessment during your free consultation.
That depends on the age and condition of your existing ductwork. For example, if it’s leaky, poorly insulated, or undersized, your new system could be less efficient. During our inspection process, we’ll let you know the recommended course of action.
We recommend at least one tune-up per year. The ideal time period is in the fall season before you start using it regularly. Annual maintenance like this keeps your system running smoothly and safely, and helps to prevent breakdowns when you need it most.
Square footage, ceiling height, insulation quality, window types, duct layout – each of these factor in to furnace size requirements. We’ll evaluate your home to make sure you get an appropriate furnace size for your home.
You should change your furnace every 1 to 3 months depending on usage and filter type. Try to schedule it for early October, around New Year’s, and again before spring time.
Furnace installations often require a building permit. This ensures everything is done to code and protects you from safe or unlicensed work.
