How to Choose the Right HVAC System

Your HVAC system helps keep your family comfortable and safe. Most modern systems last for decades, which can save money but also makes it more difficult to choose a new machine. Terms like two-stage, modulating, ductwork, and SEER can sound foreign. Selecting a new HVAC system, however, isn’t as hard as it may seem.

First, check the condition of your ductwork. If it is in good shape, you can save money and time by using it. Of course, this doesn’t apply to purchasing a setup for a brand new home, because you’ll install the system for the first time.

Choosing the Right Furnace

In Leesburg and the surrounding areas, the average low temperature in January is right around 26ºF. This means your furnace is arguably the most important part of your HVAC setup. There are single-stage, two-stage, and modulating furnaces. Choose the type that suits your needs and budget.

  • Single-stage. This kind only blows high, regardless of the temperature outdoors or indoors. It may be cheaper upon installation but it causes greater fluctuations in temperatures.
  • Two-stage. This system uses high and low settings. It’s more efficient than the single-stage system, because it can blow more softly when the temperature is only a few degrees off.
  • Modulating. This furnace type is the newest and most efficient setup. It can blow at different speeds for better airflow and a more comfortable environment. It has the highest upfront cost but results in less energy consumption and lower utility bills.

In some cases, you may also need to choose your blower. As with furnaces, there are single-speed and variable-speed blowers, enabling you to select the best fit for your home. Single-stage blowers may be cheaper and easier for smaller homes, while two-stage systems are more efficient.

Picking the Right AC Unit

The size of the air-conditioner unit is important. The machine must able to handle the workload. If it’s too small, it’ll run more often and wear down much faster. If it’s too large, you’ll waste energy starting it. HVAC professionals, such as Climatic, can calculate your needs based on the size of your home, and the brand of the unit and its efficiency.

SEER (seasonal energy efficiency ratio) ratings are the measure of efficiency. The higher the number, the more efficient, but expensive, the unit will be. A SEER rating of 13 is the minimum. A rating of 16 or higher will likely negate returns due to the upfront cost. Ratings of 14 and 15 are good numbers for a balance of efficiency and cost.

Choosing an HVAC setup is easier than you think. Contact your local HVAC professionals at Climatic for help.
