Bowie asks a lot of a heating and cooling system
Your system in Bowie works nearly eleven months of the year. Heat runs October through April, seven months, with winter nights averaging 28°F. Cooling picks up in June and holds through September, with afternoons averaging 86°F. There is barely a break between the two.
That long a season means a new furnace or heat pump has to hold up through a lot of on and off cycles before spring even arrives, and a new air conditioner has to carry full summer afternoons for four straight months. Over half the homes here heat with gas, so a gas furnace sized right for the house matters as much as the air conditioner paired with it. Storms are part of the picture too. Prince George's County has seen 222 damaging wind events and 10 winter storms over the past ten years, and statewide, 11 percent of households lost power for at least 24 hours in 2024. A new system installed here has to be able to start back up on its own once the power does.

Maryland requires HVAC contractors to hold a state license.
The state tests the contractor before handing out that license, and the Board keeps a record of who holds one. That record follows the business, not the job, so the same license covers this installation and every other one that contractor takes on.
Most cities and counties require a permit for a new heating and cooling system, and an inspector checks the completed work once it's done. The license tells you the state tested this contractor. The permit and inspection are what confirms this particular installation was done right.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense or the system can't keep up anymore. If your furnace or air conditioner is breaking down every year, or a repair costs a large chunk of what a new system would, that's your sign. A failure during the October through April stretch when homes here need heat leaves you without options if the system can't be patched quickly. Rising energy bills with no other explanation often mean the system is working harder than it used to.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. Your furnace and air conditioner often share a blower and coil, so replacing one but not the other can mean mismatched parts that don't perform the way they should. Doing both at once also means one visit, one permit, and one inspection instead of two. If one unit is much newer than the other, a contractor can tell you whether it's worth keeping or better to replace together.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner and sets the new ones in place, connecting them to your ductwork, gas line or electrical circuit, and the refrigerant lines that run to the outdoor unit. They'll also handle the thermostat and check that airflow and refrigerant levels match the equipment's specs. In most cities and counties, this job needs a permit from the local building office and an inspection once the work is done. A licensed contractor pulls that permit and schedules the inspection as part of the job.
