Tired of one room being too hot while another is freezing? HVAC zoning systems from TwinStar Air Conditioning & Heating LLC let you control the temperature in different areas of your home independently—no more thermostat wars. Perfect for two-story homes, finished basements, and homes with hot/cold spots throughout New Caney, Kingwood, Porter, Atascocita, Humble, and North Houston. Owner Erick personally designs and installs every zoning system to maximize comfort and energy savings—no cookie-cutter solutions.
An HVAC zoning system divides your home into separate climate-controlled zones, each with its own thermostat and independent temperature control.
Only heat or cool the rooms you're actually using. No more wasting energy conditioning empty spaces.
Everyone gets their preferred temperature. Keep bedrooms cool for sleeping while the living room stays warmer.
Two-story homes typically have upstairs 10-15°F hotter than downstairs. Zoning fixes this.
Your system runs less because it's not working to condition the entire house constantly. Less wear = longer life.
No need to replace your AC or furnace. Zoning adds onto what you already have (if your system has sufficient capacity).
Control humidity and airflow in specific areas. Keep the basement dry while the upstairs stays comfortable.
Divides your home into two separate temperature zones (typically upstairs/downstairs or front/back).

"We'll evaluate your system and let you know if zoning makes sense—or if a different solution would be better. No pressure, just facts."
Before recommending zoning, Erick verifies your existing HVAC system has enough capacity to support multiple zones. Undersized systems won't work well with zoning.
We don't just divide your home arbitrarily. We consider sun exposure, room usage, insulation, and existing ductwork to create zones that actually solve your comfort problems.
We use commercial-grade motorized dampers and reliable control panels—not cheap residential-grade equipment that fails after 2 years.
We access ductwork carefully, secure all dampers properly, and test every zone thoroughly. Your home is protected throughout installation.
Our quote includes everything—dampers, thermostats, control panel, labor, and testing. No surprise charges.
It depends on your system's capacity and age. If your furnace/AC is properly sized and less than 10 years old, zoning usually works great. If your system is undersized or near the end of its life, we may recommend replacement instead. We'll evaluate your system and give honest recommendations.
Most homeowners save 20-30% on heating and cooling costs by only conditioning the zones they're actively using. Two-story homes see the biggest savings since you're not over-cooling the upstairs or overheating the downstairs.
Most homes work best with 2-3 zones. A typical setup: Zone 1 (first floor living areas), Zone 2 (upstairs bedrooms), Zone 3 (basement or bonus room). We'll assess your home and recommend the optimal number of zones.
Technically yes, but it's usually not recommended. If your system is 12+ years old, you're better off replacing it with a new, properly-sized system that's designed for zoning from the start.
Yes, each zone gets its own thermostat. You can choose basic digital programmable thermostats or upgrade to smart Wi-Fi thermostats (Nest, Ecobee, Honeywell, etc.) for remote control.
Most zoning installations take 1-2 days depending on the number of zones and ductwork accessibility. We'll give you an accurate timeline during the free assessment.
Not if designed properly! That's why professional installation matters. We add bypass dampers if needed to maintain proper air pressure. DIY zoning or poorly designed systems can damage your HVAC, but professional installations don't have this problem.
