A system that has to work almost every month of the year
In Chester, heat is on from October through April and the air conditioner picks up from May through September. That is 12 months of one system or the other running, with winter nights averaging 30°F and summer afternoons averaging 87°F. Whatever gets installed has to hold up on both ends, not just get through one season easily.
Most homes here heat with electricity, so a lot rides on that system staying up. Chesterfield County has seen 9 winter storms and 138 damaging wind events over the past ten years, and across Virginia, 22% of households lost power for at least a day in 2024. A new furnace or heat pump should be sized and installed to do its job on the coldest nights and the hottest afternoons, not just on the mild days in between.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors tests and licenses the contractor as a business, not the job itself. That license follows the company from one house to the next, so the same license applies whether the job is small or large. Virginia does carve out an exception for small jobs. Work under $1,000 does not need a licensed contractor. A full heating and cooling system installation runs well past that line, so the license requirement applies here.
That license covers the contractor. It does not cover the permit for this specific job. In most cities and counties, installing a new furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets inspected once it is done. That permit and inspection are separate from the state license, and they apply on top of it.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that repairs keep coming back, or a repair costs a large share of what a new system would, replacement makes more sense than another fix. Age matters too. A furnace or air conditioner working hard to get through 7 months of heating and 5 months of cooling here every year has less time to rest than one in a milder climate. If your system is struggling to keep up on the coldest nights or hottest afternoons, that strain adds up faster than the calendar suggests. A contractor can look at the age, the repair history, and how the system is running now and tell you whether it is worth fixing again.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at the same time are matched to work together, and replacing one while keeping an old one can mean the new part is limited by the old one. If your furnace is failing but your air conditioner still has years left in it, there is no need to replace both just because one is due. A contractor can check the age and condition of each system and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner, or heat pump and sets the new equipment in place, then connects it to your ductwork, electrical, and, for gas furnaces, the gas line and vent. Refrigerant lines get connected and the system is tested to make sure it heats and cools the way it should before the job is called done. In most cities and counties, this work needs a permit from the local building office and an inspection once the installation is finished. Virginia also requires the contractor doing the work to hold a state license, so it is worth confirming that before the job starts.
