Finding The AC Unit That Is Right For Your Home

Comfortability Features

When deciding on an AC unit for your home, the first thing you should consider is whether or not the unit has the right comfortability features for you and your family. For example, a single-stage air conditioner is the most basic model, only offering the option to turn air flow on or off. This means once the home reaches the desired temperature, the unit simply turns off until it needs to cool the home again. On the other hand, a variable-speed air conditioner can provide air flow in different increments, leading to a more consistent temperature of the home around the clock. At Stan’s AC, we are happy to walk you through the different comfortability features of the units we offer.

Humidity Control

Humidity levels inside the home are often the reason for that sticky and uncomfortable feeling that comes from an underperforming AC unit. In order to cool your home, AC units pull humidity and heat out of the home while utilizing the system’s blower to circulate and cool the hot air. Variable-speed AC units provide superior humidity control due to their ability to run for longer periods of time at lower speeds. This allows the unit to spend more time pulling humidity out of the air when compared to AC units with two or single-stage compressors. Humidity control is an especially critical factor when it comes to central Texas homes, as these areas tend to have generally higher humidity levels.

Sound Levels

Air conditioning units with variable or multi-stage compressors provide nearly silent operation when compared to units with single-stage compressors. Certain air conditioning models are designed with this in mind, and include sound blankets or proprietary technology to further silence the sounds produced by the unit. For homes where the AC unit is located nearby a bedroom window or patio, this is an important feature of your system to consider. Nobody wants to hear an AC unit when they’re trying to go to sleep or have a conversation. At Stan’s AC, we’ll help you find the right unit based on the location of the system as it relates to the residents of the home.

Energy Efficiency

All air conditioning units are rated by their seasonal energy efficiency ratio, also known as SEER. Air conditioning units receive SEER ratings similarly to the way automobiles are graded on their miles per gallon. Units with a higher SEER rating will be more energy efficient than those with a lower SEER rating. Those that decide to choose an air conditioning unit with a higher SEER rating are more likely to pay less on their energy bill while leaving a smaller carbon footprint as well. Our Austin air conditioner unit professionals will be happy to walk you through the SEER ratings of our catalog, and what that may mean for your household in terms of savings on energy bills and increased efficiency.

1 Stage AC Units

Most homes in the United States are cooled with single stage or 1 stage air conditioning units. These have been the standard air conditioning unit in the United States for decades. Single stage air conditioning units turn on when indoor temperatures exceed the temperature you set on your thermostat. Once the home hits your desired temperature, it turns off again. Single stage air conditioning units get the job of cooling your home down with no frills or added features.

2 Stage AC Units

Dual-stage, or 2 stage air conditioning units offer 2 different compressor stages: high and low. This added compressor stage allows dual-stage air conditioning units to offer more consistent temperatures within the home without having to operate at full capacity. Dual stage air conditioning takes more humidity out of the air and uses less energy when compared to single stage units. Two stage units also offer additional benefits like dehumidification, air filtration, and lower energy consumption.

Variable Speed Units

Variable speed air conditioning units offer 3 or more compressor stages. This provides superior air cooling thanks to how well variable speed units dehumidify a home. The humidity that builds in a home when an AC system breaks down causes the home to feel much hotter than it is. Controlling humidity is one of the key ways to maintain comfort in your home without overcompensating with lower temperature settings. Humidity control is where variable speed air conditioning units really shine. Variable speed air conditioning units run longer than single and two stage systems, but at a low energy intake. While doing so, they force humidity out of your home and cool the air. This lack of humidity and steady cooling allows you to feel comfortable at higher temperatures and use less power, allowing you to have lower energy bills.

Our Process

1 In-home Consultation

Our team will come to your home to provide you with a free in-home consultation to assess your needs from an air conditioning unit as it relates to the size of your home, budget, and needs.

2 HVAC System Diagnostic

During our consultation, we’ll provide you with an HVAC system diagnosis. We will also offer options for improving the energy efficiency of your entire home, to save you money and keep you comfortable in ways that an AC system alone does not allow. We call this our Whole House Approach. For over 40 years, we have been reducing our customers’ heating and cooling bills up to 50% using this method. To achieve spectacular results, we know that the efficiency of the entire house must be addressed. We do this by sealing the building envelope, installing window shading, improving the ductwork, and insulating the attic in combination with repairing, cleaning, calibrating, or replacing existing HVAC equipment. Heating and cooling technology has come a long way in the last 40 years, but the “Whole House” principles are more

Capacity & Efficiency

The two basic characteristics of Air conditioning systems

Residential HVAC system capacity is measured in tonnage, an archaic industry term which refers to the quantity of heat the system can remove in an hour. Typical Residential capacity ranges from 1.5 ton units which can remove 18,000 BTUs per hour to 5 ton units which can remove up to 60,000 BTUs in an hour. An Energy Vanguard article digs into the history of “tonnage” as a measurement unit.

Larger capacity is not inherently better. Large units are generally more expensive and, if used in smaller spaces, cool air too quickly to adequately remove humidity – providing less comfort than an appropriately sized unit. Undersized AC systems may never be able to adequately cool a space. Stan’s Project Managers are expert at sizing units for a space. Your Stan’s Project Manager will make sure to recommend the right size unit(s) for your home.

Efficiency is expressed with Energy Efficiency Ratings and Seasonal Energy Efficiency Ratings. EER and SEER are related. EER is a direct measurement of a system’s cooling output compared with its energy input, using specific indoor and outdoor temperatures. The more cooling a unit produces from a single unit of energy, the better the EER. SEER applies this concept to approximate efficiency across a range of conditions, simulating an average year in a specific location. The Department of Energy mandates a minimum SEER in Texas of 14 SEER, as of 2015.
