HVAC contractors handle zoning issues

If you want to heat and cool different areas of your home with separate controls, zoning may be the best solution. Zoning can be accomplished by installing specialized equipment on one HVAC system or by installing two or more systems to serve specific zones in your home. Zoning can be an expensive investment, and you’ll need an experienced HVAC contractor to design, test, and install the system correctly to prevent problems such as uneven airflow and sagging ductwork.

Incorrect zoning installation is a common problem that can cause poor air flow throughout the home and insufficient heating or cooling in certain areas. This can be due to improperly sized equipment, insufficient ductwork or a lack of properly installed air returns and dampers. An overly-sized system can waste energy and lead to high energy bills while an undersized system will short cycle, which can result in inconsistent temperatures, poor humidity levels and excessive wear on your equipment.

Another common problem is an overly complex or inefficient zoning setup, which can increase operating costs. This can be the result of a poorly designed system, an under-trained technician or even a combination of these factors. It’s important to find an hvac contractor near me with a good reputation for quality work and excellent customer service, as well as experience working on zoned systems.

It is possible to rezone an existing system, but it is not always cost-effective or feasible. The ability to do so will depend on a variety of factors, including the design of your original installation, the availability of ductwork and the ability to add new ductwork.

A key part of any zoning system is the central control panel, which communicates with each thermostat and damper in the ductwork to open or close as needed. This is the brains of the zoning system, and it’s essential that it works correctly. When a thermostat in a zone calls for more air, the control panel sends a signal to the motorized dampers to allow more flow. When a zone is calling for less air, the dampers are closed to limit airflow.

Some zoning systems use a bypass damper to prevent back pressure build-up in the ductwork, especially on long or insufficient runs. However, this can take away from the efficiency benefits of zoning and should only be used when necessary to correct a serious problem.

Many homeowners who are considering zoning their home think that it will save them money on their energy bills, but it’s important to understand that this isn’t guaranteed. It depends on the type of equipment you have, how it’s sized and how you use the home. For example, a single-speed HVAC system cannot “gear down” when needed like a multistage system can, so it’s not as efficient when zoned. You’ll also likely pay more in maintenance and repair costs if you choose to zone a single-speed system than you would if you had two or more systems in place.
