Thanks to the hot, dry summers, homeowners in the Los Angeles, CA, area rely on their air conditioning systems to keep their homes cool. One way to achieve maximum cooling control is through HVAC zones.
What is an HVAC zoning system, and how does it work? The experienced team at Fleetwell Air Conditioning, Heating, and Plumbing has some insight into how these systems operate, their many benefits, and more to help you make an informed decision on your air conditioning upgrade.
How Do HVAC Zoning Systems Work?
An HVAC zoning system divides your home into different temperature-controlled zones. This allows you to make independent temperature settings for various rooms, offering more control and maximum energy efficiency.
Dividing zones
Rather than using one thermostat to control your entire home, a zoned system divides your home into multiple zones. These zones may include separate floors, specific rooms, or other areas where you may have different cooling and heating needs.
Each zone has a separate thermostat that lets you set and adjust the temperature for each zone independently (or turn it off altogether).
Dampers control airflow
HVAC dampers are installed in your ductwork to help regulate the air or airflow going to each zone. A central control panel directs the operation of the HVAC equipment and the dampers. This process directs the conditioned air to specific zones. Damper actuators are mechanisms added to open and close the dampers and are controlled automatically based on the instructions provided via the control panel.
The control panel changes the settings
Once the zoned HVAC is installed, the control panel serves as the “brains” of the system. This panel receives data from the different thermostats and then instructs the various dampers to open and close. Digital thermostats and control panels make it easy for homeowners to control and set temperature preferences for each zone.
You can also schedule temperature changes for specific times of the day or night for maximum comfort and optimum performance.
Ductwork changes
In some cases, a newly installed zoned HVAC system may require some ductwork modifications. A bypass damper might be required to provide balanced airflow and to maintain the right pressure. Some systems work without having to make any changes to the ductwork, but this should be determined by an experienced HVAC professional.
Single-Zone vs. Multi-Zone HVAC
It’s important to know the differences between a single-zone vs. multi-zone HVAC before you upgrade your home’s system.
Single-zone
Most homes have a single-zone HVAC system that cools and heats your entire home using just one thermostat. If you have a smaller home, a single-story home, or prefer more uniform temperatures throughout your space, a traditional single-zone system should suffice. This option is less expensive than a multi-zoned HVAC system and is easier and quicker to install.
Multi-zone
If you have a larger or two-story home, a multi-zone HVAC system gives you more precise temperature control. This energy-efficient HVAC system provides energy savings by only heating or cooling the areas you want it to.
However, it’s much more complex to install, which means it has a higher initial cost. Plus, a multi-zone system requires more equipment and maintenance due to the complexity of the ductwork and other components.
Benefits of HVAC Zoning Systems
There are a lot of positive HVAC zoning system benefits if you’re considering this type of home comfort system.
Improved comfort
A zoned system lets you set different temperatures for different areas of your home, improving overall comfort. You can choose to keep your bedroom cool at night while turning the rest of the house “off” while you’re asleep to save money. It’s also a great way to feel more comfortable in the most-used areas of your home during the day, such as the kitchen and living room.
Better energy efficiency
A multi-zone HVAC system costs more to install upfront, but it saves you money over time with its exceptional energy efficiency. If you have a large home or infrequently used areas, these systems help maximize usage where it counts the most while minimizing usage where it’s not needed. The result is less waste, improved system efficiency, and lower energy bills.
Potential tax rebates and credits
A zoned HVAC system is considered an energy-efficient upgrade, so you may be eligible for tax rebates, credits, and more. The state of California offers a tax credit for homeowners who install a high-efficiency heating or cooling system in their primary residence before December 31, 2032. The federal government also has several energy-efficient home upgrade tax incentives as part of the Inflation Reduction Act.
Other benefits
A zoned system improves indoor air quality by minimizing the spread of pet dander, dust, and a variety of other airborne particles and contaminants. The long-term energy savings far outweigh the upfront cost, giving you the maximum return on your investment.
A well-designed and maintained multi-zone HVAC system is a terrific selling point, helping to boost your home’s overall resale value if you ever decide to sell.
Cost Considerations for HVAC Zoning Systems
Whether you’re getting a two-stage furnace or a multi-zone HVAC system, there are several things to consider when it comes to cost.
- Ducts vs ductless: Most traditional HVAC systems require ductwork, but ductwork isn’t necessary with a ductless mini-split zoned system, so it could cost you less to install.
- Thermostats: Since multi-zone systems use more than one thermostat, you’ll need to consider the cost of each additional thermostat when you make the upgrade.
- Number of zones: Your cost for a new multi-zone system depends on how many zones you need. The more zones, the higher the total cost.
- Control panel: The control panel is an additional piece of equipment you’ll need to pay for and have professionally installed.
- Ductwork modifications: If changes to your existing ductwork are required, prepare to pay for the cost of labor and materials needed to make the modifications.
- Additional units: Larger homes may require more than one HVAC unit, which increases the cost of installing a new multi-zone system.
- Other equipment: You may need to pay for dampers and sensors, depending on your zoned HVAC setup.
Upgrading Your Existing HVAC System With Zoning
If you’re looking to get more control over the indoor temperature in your home, upgrading your HVAC system with zoning is a wise choice. These systems also help you save on energy costs. Plus, tax incentives like credits and rebates help to offset the total upfront cost.
