How To Choose An HVAC System

To choose an HVAC system, it seems like you have to be a professional. There are so many terms, ratings and features…how is the average person supposed to know which system to choose? Don’t worry, we’re here to help! Let us tell you more about how to choose an HVAC system.

Size

As a rule of thumb, air conditioners with a 15,000 BTU rating should be able to cool rooms up to approximately 875 sq. ft. HVAC systems are sized according to their cooling capacity (which are expressed in BTU per hour), so your first consideration is to match the air conditioner to the room you want to cool. If the unit is too large, it will cool the space so quickly that the thermostat will shut the unit down without lowering the humidity level. If the unit is too small, it will overwork, but won’t cool the space.

Cooling Capacity

Cooling capacity is dependent upon square footage, windows, sun exposure, insulation, room use, etc. You can use a simple air conditioning calculator available from The Association of Home Appliance Manufacturers to determine the cooling capacity of your space. Most units you’ll see in stores compare the square footage of the room to BTU capacity.

Controls

Control options are important when shopping for an air conditioner. Look for multi speed fans and adjustable thermostats. Both of these will help you achieve maximum comfort and switch to lower settings for a quieter operation. More precise control is offered by digital controls, with features such as preset scheduling and timers to control certain temperatures at certain times. This feature can ultimately save you money and your unit efficiency!

Filters

During the peak cooling season, your AC filter should be replaced every 3-4 weeks. For this reason, you should check the AC units you’re shopping for to see how easy (or hard) it is to replace the filter. If it is hard for you to reach or replace, the less likely you are to do it. Try to find one that simply slides up and down without any screws or other fasteners.

Efficiency

Last, but certainly not least, consider efficiency. Manufacturers are required to list the energy rating directly on the unit, making an easy determination of energy efficiency. The EER, or Energy Efficiency Ratio, is the cooling capacity divided by the electrical power required to run the unit. The higher the number, the better. Any unit with an EER above 10 is extremely efficient. Of course, with a higher EER also comes a higher price tag. Keep an eye out for the Energy Star logo. Energy Star products are certified to be 15% more efficient than those meeting the minimum federal requirements.
