Eleven months of work a year in Chestertown
Winter nights average 28°F from December through February, and homes here need heat from October through April, seven months a year. Summer afternoons average 86°F, and cooling runs June through September. Between the two, a new system is working eleven months a year.
Most homes in the area heat with electricity, so a heat pump's output on a 28°F night is worth checking before you install one. Kent County has seen 8 winter storms and 98 damaging wind events over the past ten years, and across Maryland, 11 percent of households lost power for at least 24 hours in 2024. A furnace or heat pump that comes back on by itself once power returns matters here.

Maryland requires HVAC contractors to hold a state license.
The Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors tests contractors before it licenses them and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license covers this installation and the next one down the street.
For a system installation, that license is what stands behind the person doing the work. Most cities and counties also require a permit from the local building office for a job like this, with an inspection once the work is done, and that check runs alongside the state license rather than in place of it.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth or when the system can no longer keep up on the coldest or hottest days. If a contractor has been out more than once this year for the same problem, that's usually a sign the equipment is on its way out rather than just having a bad week. Homes here need heat from October through April and cooling from June through September, so a system that struggles in either season leaves you without much margin. Age matters too. A contractor can tell you whether your specific unit is worth repairing again or replacing now.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is usually the better move, but it depends on the condition of each one. A furnace and air conditioner installed years apart can end up mismatched in a way that hurts how well they work together, since they're built to run as a pair. Winters here average 28°F and summers average 86°F, so both sides of the system carry real work most of the year. A contractor can look at the age and condition of each unit and tell you whether replacing one now and the other later makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment in place and connects it to the ducts, refrigerant lines, gas or electric supply, and thermostat. Once everything is connected, they test the system to check airflow, pressures, and that it cycles on and off the way it should. In most cities and counties, this job needs a permit from the local building office and an inspection when the work is done. Maryland also requires the contractor doing the work to hold a state HVAC license, so it's worth confirming that before the job starts.
