Princess Anne asks a lot of a furnace

Heat has to run October through April here, seven months of the year. Winter nights average 30°F, cold enough that a furnace cycles on and off for most of the night to hold the house steady.

56.4 percent of homes in the area heat with electricity, so a power outage can mean no heat at all. Over the last ten years the county has seen 11 winter storms and 29 damaging wind events, and in 2024, 11 percent of Maryland households lost power for 24 hours or longer. A new gas furnace installed today has to meet the federal minimum of 80 percent AFUE, so whatever goes in will hold to that standard from the start.

Maryland requires HVAC contractors to hold a state license.

Maryland tested this contractor before handing out that license, and the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors keeps a record of who holds one. That license belongs to the contractor, not to any one job. It says the person or company showing up has met the state's standard.

For this furnace, the license is what stands behind the contractor. The permit is what stands behind the work itself. In most cities and counties in Maryland, putting in a new furnace requires a permit from the local building office, and the finished work gets inspected once it is done, including the gas connection, since that is the part of the job where a mistake is dangerous.

What size furnace does my house need?
The right size depends on your square footage, your insulation, your windows, and your home's layout, so there's no single number that fits every house. A contractor works this out with a load calculation, not a rule of thumb based on square footage alone. Too big and the furnace short cycles, heating the house in bursts and wearing out faster. Too small and it runs constantly through those 30°F winter nights and still can't keep up. Ask whoever quotes the job to walk you through the load calculation before they recommend a size.
How do I know it's time to replace my furnace?
Age is the first thing to check. A furnace installed today has to meet 80 percent AFUE at minimum, so if yours is much older than that standard, it's likely running well below it. Rising bills without a change in how you use the house point the same way. Repairs that keep coming back, or a repair bill that starts to rival what a new furnace costs, are usually the sign. Since homes here need heat from October through April, a furnace on its way out tends to show it over a long stretch, not just on the coldest nights.
Is a high-efficiency furnace worth it?
It depends on how long you plan to stay in the house and how much you're paying now to heat it. A high-efficiency furnace costs more upfront than one built to the 80 percent AFUE minimum, and it earns that back through lower gas or electric use over the years you own it. With heat needed here seven months of the year, the difference shows up on more bills than it would somewhere milder. A contractor can run the numbers against your current furnace's efficiency and your actual usage to tell you where the payback lands for your house.
