Seven months of heat, most of it on electricity
Winter nights in Chesapeake Beach average 29°F from December through February, and homes here need the furnace running from October through April. That is seven months a year of a burner or a heat strip cycling on and off to keep up.
Most homes in this area heat with electricity, which means a power outage takes the furnace down with it. Calvert County has seen 12 winter storms and 120 damaging wind events over the past ten years, and last year 11% of Maryland households lost power for a full day or more. A new furnace installed here also has to meet the federal minimum of 80.0 percent AFUE if it runs on gas, so whatever goes in is built to hold up through a long, cold season.

Maryland requires HVAC contractors to hold a state license.
The license comes from the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors, and the state tested the contractor before issuing it. That license belongs to the contractor, not to any one job, so it does not expire when your furnace is installed and it does not need to be renewed for the next homeowner who hires the same company.
For a furnace installation in Calvert County, the license tells you the contractor is who the state says they are. The permit is separate. Most counties and cities require a permit for a furnace replacement and an inspection once the work is done, and that inspection is what checks the gas connection and venting on this specific job, not the license.

- What size furnace does my house need?
- It depends on the size of your house, how well it's insulated, your windows, and your ceiling height, so there's no single number that works for every home. A contractor sizes a furnace with a load calculation that looks at all of that together, not just square footage. Putting in a furnace that's too big or too small for the house leads to short cycling or a house that never quite gets warm, so this step matters more than the brand or model you pick.
- How do I know it's time to replace my furnace?
- An old furnace that needs more repairs each year is usually telling you something. Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a jump in your gas or electric bill with no other explanation. Winter nights here average 29°F, and homes need heat from October through April, so a furnace that's struggling has seven months a year to prove it. If a repair is going to cost close to what a new furnace would, replacing it usually makes more sense than patching an old one again.
- Is a high-efficiency furnace worth it?
- Any new gas furnace installed today has to reach at least 80 percent AFUE by federal rule, so that's the floor, not a special upgrade. High-efficiency models go higher than that, meaning more of the fuel you burn turns into heat in your house instead of going out the flue. Whether the higher upfront cost pays off depends on your fuel type, your usage, and how long you plan to stay in the house, so a contractor can walk through the actual models and their ratings for your situation.
