SIZING HVAC SYSTEMS

When choosing an HVAC system for your home, bigger is not necessarily better. In the past, it was very common to hear, I want to make sure my house gets nice and warm during the winter, so I want the biggest unit you have. Oversized HVAC equipment is actually a big problem, and here are a couple of reasons why.

Inefficient Operation: Oversized HVAC equipment tends to cycle on and off frequently, leading to inefficient operation. When the system starts, it ramps up quickly and reaches the desired temperature rapidly. As a result, it shuts off before completing a full heating or cooling cycle. This short cycling wastes energy and puts unnecessary strain on the equipment, reducing its overall efficiency, and consumes more energy in the process.

Comfort Issues: Larger HVAC systems can create temperature disparities and discomfort in different areas of your home. They may struggle to distribute conditioned air evenly, resulting in hot or cold spots. Properly sized systems have a better chance of maintaining consistent temperatures and providing enhanced comfort throughout the house.

Increased Equipment Wear and Tear: Short cycling and frequent on/off cycles put additional stress on the HVAC equipment. This can shorten the lifespan of the equipment and result in more frequent breakdowns, repairs, and the need for premature replacements.

Initial Cost: Larger HVAC systems tend to come with a higher upfront cost due to their increased capacity. You may end up paying more for equipment that surpasses your actual heating and cooling needs.

To avoid these issues, it is crucial to have an HVAC system that is properly sized for your home’s heating and cooling load. It is always best practice to contact a reputable HVAC technician to ensure that the equipment is correctly sized to your specific needs. This will lead to improved efficiency, comfort, and long-term cost savings. For more information, please give us a call 604-948-9949 or send us an info@acornheat.com.
