Do you need a new HVAC installation or heating and AC replacement in Austin? The experts at McCullough Heating and Air Conditioning have put together the information you need to make the right decisions for your home comfort system. In Part 1, we discuss proper HVAC sizing and design.
How Important Is Proper Design?
From the ductwork to the placement of air vents, designing an HVAC system involves more than the furnace, heat pump, AC or other units in your home. Without a properly designed HVAC system, you could end up with an oversized or undersized AC installation that sends your energy bill skyrocketing. Here are just a few other things that can go right or wrong, depending on the quality of your HVAC design:
- With the right sizing you get significantly higher energy efficiency (SEER) with the unit you purchased. With the wrong sizing, energy efficiency tanks.
- Energy usage and costs pivot on how efficiently your system operates. An undersized or oversized unit will work too hard to heat and cool your Austin home.
- Austinites love the wonderful weirdness of the city, but inconsistent temperatures in your home aren’t cool. We can design a system that’s just right for your home’s needs to maximize energy efficiency.
- With the right design, you can enjoy warm or cool air without an obnoxiously loud operating noise or high energy bills.
These are just some of the reasons it’s important to get your HVAC system design right.
What Makes Austin HVAC Load Calculations Unique?
Austin mainly falls within ASHRAE’s 2A Climate Zone. It’s right on the cutover to another climate area. Changing weather poses unique challenges to calculating the HVAC load. Our local HVAC technicians take into account the similarities of both oceanside climates and inland climate characteristics. With all these considerations, it’s important to find a trusted HVAC contractor to get it right.
What Factors Impact the Load Calculation?
There is no educated guessing allowed when sizing your HVAC replacement. Insist on a contractor that uses a Manual J calculation to quantify your heating and cooling needs. This standard provides a much more accurate measurement of your HVAC needs than merely taking a few measurements.
Proper design also takes other considerations into account, such as:
- Size and construction type of the home
- Position of the home compared to sunrise and sunset
- Foundation and roof construction
- Heat sinking ovens, computers, and televisions
- Number of people and pets

Why Bigger Is NOT Better?
It takes 10 to 15 minutes for your system to operate at peak performance. Therefore, this is when the most wear and tear occurs on your system. Oversized systems bring the temperature down to the temperature setting in minutes. Unfortunately, this causes the system to constantly turn on and off continuously. So, bigger ACs aren’t better for AC replacement.
