Marion County asks a new system to cool more than it heats
Cooling season here runs March through October, 8 months of the year. Summer afternoons average 91°F, and whatever you install will spend most of its life running that side, not the heating side. Winter only asks for heat from December through February, on nights that average 47°F, but a new system still has to handle both without one side being an afterthought.
That's 11 months out of the year where a home here needs one or the other. Most homes in the area heat with electricity, so the equipment you choose is doing almost all the work, year round, on a single fuel. Marion County has also seen 156 damaging wind events over the past ten years, and in 2024, 38% of Florida households lost power for 24 hours or more. Worth asking about how a new system handles a power interruption before it goes in, not after.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense against the age of the unit, or when it can't keep up anymore. Once a system gets old, parts wear out faster than you can chase them, and a contractor can tell you whether the one in your house has reached that point. Watch for rising bills with no other explanation, rooms that won't hold their temperature, and a system that runs longer to do the same job it used to do quickly. If something major just failed, like the compressor or the heat exchanger, and the unit is already old, that's usually the point where replacing makes more sense than repairing.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to replace them together. A furnace and air conditioner often share a blower and coil, so pairing a new one with an old one can leave the new unit working around parts it wasn't matched to. Homes here need cooling from March through October and heat only from December through February, so the air conditioner does most of the work and tends to wear out first. If your furnace still has years left in it, a contractor can tell you whether it's worth replacing now or waiting until it actually needs it.
- What happens during an HVAC installation?
- A contractor starts by sizing the new system to your house, checking the ductwork, and removing the old equipment. The new furnace, air conditioner, or heat pump goes in along with any electrical, gas line, or drain line work it needs. Once it's connected, the contractor tests it, checks refrigerant charge and airflow, and walks you through the thermostat and any settings specific to the equipment. A contractor can walk you through the exact steps and timeline for your house.
