Eleven months of work, not one
Your system in Kent County only gets a short break. Heat from October through April, cooling from June through September. That leaves one month where it can sit idle, and most years it doesn't get even that.
Winter nights here average 28°F, so the furnace cycles on and off for hours at a stretch, and each start puts wear on the igniter and the ignition control board. Summer afternoons average 86°F, which keeps the compressor running long and hard through the day. Add in the wind. Kent County has seen 98 damaging wind events over the past ten years, and wind like that can knock loose an outdoor unit's wiring or drop tree limbs on the line running to it. When the power drops, most furnaces and air conditioners come back on by themselves, but 11% of Maryland households were without power for a full day or more in 2024, long enough for pipes to chill or a house to heat up past comfort.

Maryland requires HVAC contractors to hold a state license.
The Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors issues that license, and it tests the contractor before letting them hold it. The license belongs to the contractor, not to any single job, so the same license that qualifies them to repair your system also covers the next one they take on.
For a repair job in Kent County, that license is what stands behind the person working on your system. Maryland's board is the record to check, since it is the one testing and licensing body behind the work, whatever the repair turns out to need.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above the room temperature, and check that it has power if it uses batteries. If the thermostat looks right, check your breaker panel for a tripped breaker, since a furnace or heat pump that lost power will not run at all. Gas furnaces will also shut down if the pilot or igniter fails, and a licensed contractor can check that safely. With winter nights here averaging 28°F, a furnace that will not start is worth calling in on the same day.
- Why is my system running but not cooling the house?
- Check the filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can ice over and stop cooling the air even though the blower keeps running. Next check that all the supply vents in the house are open and not blocked by furniture or rugs. If the filter is clean and the vents are clear and the air still is not cold, the system may be low on refrigerant or have a failed part, and that needs a licensed contractor to diagnose. On an 86°F afternoon a system that is only moving air, not cooling it, will let the house heat up fast.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first. Then check your breaker panel, since a tripped breaker will stop a furnace, heat pump, or air conditioner cold. Check the filter next and replace it if it is dark with dust, since a blocked filter can stop airflow and cause icing or overheating. If the system still is not working after that, a licensed contractor can diagnose what the filter and breaker check will not show, like a failed part or a refrigerant leak. Maryland requires HVAC contractors to hold a state license, so ask for that license before any repair work begins.
