Eleven months of work, most winters below freezing
A new system in Blacksburg needs heat from October through May and cooling from June through August. That is eleven months of the year one machine or the other is running. Winter nights average 26°F from December through February, so a furnace or heat pump here spends most of the year working against real cold, not just taking the edge off. Summer afternoons average 82°F, enough that the cooling side still has to earn its keep in the months it runs.
Most homes in this area heat with electricity. When storms come through, that matters. Montgomery County has logged 18 winter storms and 94 damaging wind events over the past ten years, and a large share of Virginia households lost power for a full day or more in 2024. A new heating and cooling system installed here should be sized and set up for that mix. Long stretches of cold, a real summer, and the chance the power goes out in the middle of either one.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors tests and records the contractor, not the job. That license stays with the company, so it covers this installation the same way it covers any other job they take on. Virginia only steps back from this for small work, anything under $1,000, which is well below the cost of putting in a heating and cooling system.
Because this is an installation, Montgomery County's building office will also have a say in it. Most local building departments require a permit for a furnace, air conditioner or heat pump replacement, and an inspector checks the work once it's done. That inspection is separate from the state license. The license tells you the contractor was tested and is on record with the state. The permit and inspection tell you the finished installation was checked in your home.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense, either because the system is old or because it keeps breaking down. A contractor can tell you whether the unit you have is worth another repair or not. Homes here need heat or cooling 11 months out of the year, so a system that is struggling does not get much of a break between seasons.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, it usually makes sense to replace them together. A furnace and air conditioner installed at the same time are matched to work well with each other, and doing the work in one visit means one round of ductwork checks and one inspection instead of two. If only one of them has failed and the other still has years left, a contractor can tell you whether it is worth waiting.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner, sets the new equipment in place, and connects it to the ducts, gas or electric lines, and condensate drain. On a central air system this includes the outdoor unit and the indoor coil, which work together to cool the air moving through the ducts. Once everything is connected, the contractor tests the system and checks the airflow. In most cities and counties this job needs a permit and an inspection when the work is done, so plan for that step before the system is signed off.
