How to choose a new HVAC system

When it comes down to choosing a new HVAC system there are several factors to consider.

Firstly, new HVAC system needs to be properly sized for your home. You don’t want to choose an HVAC system that is too big and too small; you need the right size equipment for the most efficient operation.

Secondly, you need to select the right efficiency level of a new HVAC system. High Efficiency Air conditions come in SEER (Seasonal Energy Efficiency Rating) and can vary between 13-20 SEER. The higher the SEER the more energy efficient is air conditioner. High Efficiency furnaces come in AFUE (Annual Fuel Utilization Efficiency-%) and vary between 92 % AFUE and 98% AFUE. The higher the AFUE % the better.

Next step in selecting new HVAC system is single or two stage equipment. You have an option of a single stage air conditioner compressor at one constant speed at all times irrelevant of the outside temperature or a two stage compressor that runs at a lower setting most of the times and goes into a high speed only when needed. Same goes with selecting a single stage furnace that keeps the flame at the same level at all times vs two stage furnace that save you energy by using lower or higher settings based on the outside temperature. This not only saves energy but also extends the lifespan of the equipment by preventing the unit from cycling on and off as frequently.

Selecting the right blower in HVAC system can also help in even air distribution throughout your home. Blower comes with similar options as the compressor. Single speed blower constantly operates at high speed delivering the same amount of air through the home. Multi speed blower has different speed levels to blow air faster in extreme weather and lightly in mild weather conditions.

Knowing your options can help you save money on energy and ensure that your home feels comfortable at all times. For more advice on selecting a new HVAC system that is right for your home contact DeMark Home Ontario at 647-847-2998 or submit an online inquiry.
