A new system here works most of the year
Salisbury asks a lot out of a heating and cooling system. Winter nights average 29°F from December through February, and summer afternoons average 86°F. Add it up and the system you install runs 11 months out of 12, heat from October through April and cooling from June through September.
Most homes here heat with electricity, so the new system is doing the cold-night work as well as the hot-afternoon work, not just one or the other. Wicomico County has seen 12 winter storms and 68 damaging wind events over the past ten years, and across Maryland, 11% of households went at least 24 hours without power in 2024. Whatever gets installed should be able to come back on by itself once the power does.

Maryland requires HVAC contractors to hold a state license.
Maryland licenses HVAC contractors through the Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors. The state tests the contractor and keeps a record of them, and that license is tied to the business, not to any single job. It covers the contractor across every installation they do, not this one alone.
For your installation, that license is what stands behind the person doing the work. In most cities and counties, including here, replacing a furnace, air conditioner or heat pump also needs a permit from the local building office, with an inspection once the work is done. The inspection checks the installation itself, separate from what the contractor's license already covers.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense or the system can no longer keep up on the coldest or hottest days. An old furnace or air conditioner breaks down more often, and each repair is money on top of a unit that is already near the end. If yours is heating or cooling unevenly, running constantly, or a contractor has already been out more than once this year, that is usually the sign. With 7 months of heating and 4 months of cooling here, a system that struggles has very little time off to hide it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, that is usually the better time to do it. A furnace and air conditioner installed together are matched to work as one system, and replacing one now while the other fails later means running mismatched equipment in between and paying for labor a second time down the road. If only one has actually failed and the other is still young, a contractor can tell you whether it makes sense to wait. Either way, a licensed contractor will price the job for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, sets the new equipment, and connects it to the ductwork, electrical, gas line if there is one, and condensate drain. The refrigerant lines get connected and the system is charged, then tested to make sure it heats and cools correctly and the thermostat is talking to it. In most places here, replacing this equipment needs a permit from the local building office and an inspection once the work is done. Maryland also requires the contractor doing the work to hold a state HVAC license.
