Why Your HVAC System Needs to Be Sized for Your Home

January 15, 2019

Sizing your HVAC system is one of the most important parts of the HVAC installation process. Optimal heating and cooling depend on the unit’s tonnage, as well as the capacity of your HVAC ducts and the layout of your Palm Desert, CA home. While there are generic rule-of-thumb calculations, sizing involves many factors beyond your home’s square footage, such as insulation levels, sun exposure and heat-generating activities.

At Palm Desert Air Conditioning and Heating Co., our HVAC contractors follow detailed sizing calculations outlined in Manuals J, D and S, which are published by Air Conditioning Contractors of America.

4 Reasons Why HVAC Sizing Is so Important

Properly sized HVAC equipment provides a higher level of comfort and reliability. It can also benefit your wallet. Here are a few reasons why accurate sizing calculations are so important.

Equipment Costs: Oversized units cost more upfront, which can unnecessarily inflate your initial out-of-pocket expenses as well as your cost of ownership.
Comfort: A properly sized HVAC system is vital for removing humidity, providing adequate airflow and controlling temperatures in all types of weather, especially when summertime highs soar above 100 degrees.
Efficiency: The unit’s capacity affects your operating costs. While oversized systems waste energy by cycling on and off frequently, undersized equipment may struggle to keep up with the heat.
Durability: Finally, due to their operating characteristics, both undersized or oversized units may suffer from premature breakdowns, which could increase your long-term cost of ownership.

HVAC Installation Methods Versus Heating and Cooling Performance

Proper HVAC installation methods are also critical for achieving optimal performance. Government experts estimate that the quality of the installation can affect the system’s efficiency by 30 percent.
