Two HVAC Units: Why Norfleet Builders Puts One on Every Floor

Tennessee weather is unpredictable. Brutal summers, freezing winters, and 40-degree temperature swings in a single week — your home's climate system has to handle all of it.

That's why Norfleet Builders installs a dedicated HVAC unit on every floor of every home we build.

The Problem with One Unit

Heat rises. In a two-story home, your upper floor can run 8–10 degrees warmer than your main floor in summer. With a single unit, you're stuck choosing: freeze the downstairs to cool the bedrooms, or sweat through every night.

Winter flips the problem. Warm air pools upstairs while main-floor rooms — especially those over a garage — stay drafty no matter how high you set the heat.

Why Two Units Changes Everything

With a dedicated system on each floor, every level of your home stays at the temperature you set — independently. Sleep cooler upstairs. Keep common areas comfortable during the day. No compromises.

There's also a practical upside: if one unit ever needs service, the other keeps running. In a Middle Tennessee winter, that's not a small thing.

Built Into Every Norfleet Home

We don't offer this as an upgrade — it's standard. Every home we build comes with one HVAC unit per floor, properly sized for that level's square footage from day one.

Comfort shouldn't be something you settle for. Let's build your home the right way.
