A system that works nearly all year, in both directions
Portsmouth asks for heat from November through April and cooling from May through September. That is 11 months where your system is either warming the house or cooling it, and only a short stretch where it gets to rest. Winter nights average 35°F, so a furnace or heat pump here is working against a moderate, steady cold rather than a deep freeze. Summer afternoons average 86°F, and the cooling side has to hold that line for five straight months.
A new system has to be sized for both jobs, not just the one on your mind right now. Storms are part of the picture too. Virginia has seen 22 damaging wind events and 6 winter storms over the past ten years, and in 2024, 22% of households in the state went at least 24 hours without power. That is worth weighing when you decide what goes in and how it holds up when the power drops.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors is the one that tests and licenses HVAC contractors in Virginia, and that license belongs to the contractor, not to any single job. It covers this installation and every other job that contractor takes on elsewhere in the state. Virginia carves out one exception, for work under $1,000, but installing a heating and cooling system runs well past that, so the contractor doing this job needs to hold that license.
The license is what stands behind the contractor's name, and in most cities and counties there is a second step besides. Installing a new furnace, air conditioner or heat pump usually needs a permit from the local building office, and the work gets inspected once it is finished. That inspection happens apart from the license itself, as a separate check on the job.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that repairs are getting frequent or expensive, it's usually time to replace rather than fix it again. Watch for a furnace that short cycles, an air conditioner that can't keep the house cool on an 86°F afternoon, or energy bills climbing with no other explanation. A newer system with a minor repair is almost always worth fixing instead of replacing. Homes here need heat or cooling 11 months of the year, so a system that's struggling doesn't get much of a break.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, it's worth doing together. A furnace and air conditioner installed at the same time are matched to work as a pair, and a contractor can connect the ductwork and wiring for both in a single job. If your furnace is failing but the air conditioner is only a few years old, there's no reason to replace a unit that still has years left in it. A contractor can look at the age and condition of each one and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, sets the new units in place, and connects them to your ductwork, gas line or electrical circuit, and the refrigerant lines. Once everything is connected, they test the system to check airflow, temperature, and that it's cycling on and off correctly. In most cities and counties, including here, replacing a furnace or air conditioner needs a permit from the local building office, and the job gets inspected once the work is done. Virginia also requires the contractor doing the work to hold a state license. A contractor will price the job once they've seen the house.
