What a system here has to handle
Winter nights in Centre County average 20°F from December through February, and homes need heat from October through May. That's eight months of real heating work, not just taking the edge off a mild day. Summer is shorter, with afternoons averaging around 80°F in July and August, but a new system still has to handle both jobs, and ten months out of the year one or the other is running.
44.6% of homes here heat with electricity, which makes a system's cold-weather performance matter more than it would somewhere milder. The county has also logged 27 winter storms and 168 damaging wind events over the past ten years, and statewide, 15% of households went at least 24 hours without power in 2024. Whatever you install, it's worth knowing how it comes back on once the power does.

Pennsylvania requires contractors to register with the state.
That registration puts the business on file with the state. There is no trade exam behind it and no license. Pennsylvania also does not let cities or counties set up their own HVAC license, so Centre County cannot fill that gap either. The registration is the only state record that exists here.
In most cities and counties, putting in a furnace, air conditioner or heat pump needs a permit from the local building office, and the finished work gets inspected before it is signed off. That inspection is what checks the gas connection and the rest of the installation, not the state registration.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they used to, or when your system can't keep up on the coldest nights or hottest afternoons anymore. A furnace or air conditioner past 15 years old is working harder than it should, and parts get harder to find as a system ages. Homes here need heat from October through May, so a furnace that struggles to keep up during those months is worth replacing before it fails outright. A contractor can look at your specific system and tell you whether repair still makes sense or if you're past that point.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often the better path, 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 pairing a new unit with an old one can mean the new one never runs at its best. Homes here need heat for 8 months and cooling for only 2, so the furnace does most of the work and may wear out first. A contractor can check both systems and tell you whether one or both need replacing.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both in place, and connects it to your ductwork, gas or electrical line, and thermostat. They check the ducts for leaks or damage, since air moving through bad ductwork won't heat or cool the house evenly no matter how new the equipment is. Once everything is connected, they test the system, checking things like airflow and, on a furnace, that it's igniting and heating properly. The job is sized to your house, so a contractor will walk you through what your installation specifically involves.
