How to Find the Right HVAC System
September 15, 2016

If you want your home to be in its best possible shape, then you need to consider the efficiency of its heating, air conditioning, and ventilation system. That means choosing the right components from the get-go. When in the market for HVAC, your may find that the number of options available to you. The sheer magnitude of information on the Internet may be difficult to sort through.

Here are some tips for how to find the right HVAC system:

Know your furnace types.

There are three basic types of HVAC system—single stage, two stage, and modulating. The type you choose will determine how your system functions, as well as how efficient it is. A single stage unit has only one setting: high. Therefore, it stays on until the temperature in your space reaches the temperature indicated on the thermostat, at which point it shuts off. Because of this on/off operation, there is more temperature variation in your space. This inefficiency is reflected in your heating/cooling bill. Two stage units have two settings, which minimizes some of that inefficiency by better regulating the temperature fluctuations. Lastly, modulating units are purported to work constantly to maintain a more consistent temperature to further increase efficiency.

Have an eye for energy efficiency.

While it is still possible to go with the old-fashioned, 80 percent efficiency models (they are least expensive units you can buy), it is not at all advisable. Any money you save now on a cheap, low-efficiency HVAC will only end up costing you a lot more money in the long run. Both in your utility bills and in maintenance. With all of the affordable energy efficient models on the market today, you simply cannot afford to skimp on this modern must-have element. Look for the white and blue ENERGY STAR logo to identify high-quality, high-efficiency HVAC models.

Determine how much heating and cooling you actually need.

Too big an HVAC system can actually decrease efficiency. Too small and the HVAC system simply won’t be able to handle the burden of heating and cooling your entire space. The amount of heating and cooling you need (or, the size of your HVAC unit) is determined by an arithmetic formula that accounts for your home’s size, insulation, and location. Ask an HVAC professional for guidance with this calculation, before you go shopping.
