A/C Replacement

Good, Better, Best Price on Trane Air Conditioners!

"It's Hard to Stop a Trane"

At Annaville Air Conditioning, we understand that achieving true comfort in your home or commercial building involves more than just installing a new air conditioning unit. Our approach recognizes that the entire structure plays a crucial role in the effectiveness and efficiency of your cooling system.

In Corpus Christi, where high humidity levels are a constant challenge, simply installing a new air conditioning unit without considering the unique demands of the environment and the structure itself would be inadequate. Similar to Southern Florida, where humidity can also be extreme, the capacity requirements and runtime necessities of your cooling system must be carefully assessed to ensure optimal comfort.

Extended Warranty

Extended Warranty covers labor and related repair costs, while Factory Warranty only covers parts. We highly recommend adding an Extended Labor Warranty with your new A/C for added peace of mind.

At Annaville Air Conditioning, we believe that if your new A/C system (no matter the brand) runs for 10 years without any issues, you’re very fortunate. In our experience, most modern systems are likely to have a major part failure within the first 5 years. While today’s A/C units are more energy-efficient than those made 30+ years ago, they generally don’t last as long or hold up as well over time. Because we work on all brands, we see the common problems each one has. We offer name-brand equipment that our technicians have found to be more reliable in the field. Our brand choices are based on real-world performance—not just marketing claims. However, even the best brands today don’t match the long-term durability of older systems. Our goal is to help you choose the most dependable option available and to keep your system running strong with expert maintenance and service.

Average cost to replace with factory parts warranty only:

Purchasing an extended warranty Is highly recommended by Annaville Air Conditioning

When you buy a new A/C unit, the factory warranty usually only covers the cost of the part itself. It does not include labor, shipping, refrigerant, trip charges, or warranty processing fees. In many cases, these extra costs can end up being more expensive than the part that’s covered. It’s important to understand what’s included—and what’s not—so you’re not caught off guard by unexpected charges.

Average Costs:

ECM motor $788
Evaporator coil $1750
Compressor $1980
Condenser coil $2210

Above charges include labor, trip charges, parts acquisition fee, warranty processing fee, shipping and miscellaneous items (freon, welding, supplies etc).

Full Service Company -vs- A/C Sales ONLY Company

Annaville Air Conditioning recommends choosing a well-established full-service company for your new A/C purchase—not a sales-only company. With a full-service provider, you get expert installation, ongoing maintenance, and reliable support long after the sale.

Basically there are 3 types of a/c companies to choose from:

Compare	Full Service Company YIWE-Annaville A/C	One Trucker Company	A/C Sales Only
Dedicated personnel to answer your call	YES	No	Maybe

About Manual J Load calculation

Manual J Load calculations are an essential part of designing an HVAC (heating, ventilation, and air conditioning) system for a building. Developed by the Air Conditioning Contractors of America (ACCA), Manual J is a methodology used to determine the heating and cooling loads for a structure based on various factors such as climate, building materials, insulation, occupancy, and more. Here's an overview of the key aspects of Manual J Load calculations:

Factors Considered:

Manual J takes into account a wide range of factors that affect the heating and cooling requirements of a building. These include the climate of the location, orientation of the building, size and layout of each room, insulation levels, windows and doors, air infiltration rates, appliances, and occupancy patterns.

Climate Data:

Manual J considers climate data specific to the location of the building, including outdoor temperature and humidity levels. This data is crucial for determining the heating and cooling loads throughout the year

Room-by-Room Analysis:

Manual J requires a detailed analysis of each room in the building to calculate its individual heating and cooling requirements. This includes measuring the size of the room, identifying heat sources such as appliances and occupants, and assessing insulation levels and air leakage.

Heat Gain and Heat Loss:

Manual J calculates both the heat gain (for cooling) and heat loss (for heating) for each room in the building. Heat gain factors include solar radiation, internal heat sources, and infiltration, while heat loss factors include outdoor temperature differentials and insulation effectiveness.

Equipment Sizing:

Based on the calculated heating and cooling loads, Manual J helps determine the appropriate size and capacity of HVAC equipment needed to maintain comfort levels in the building. Undersized or oversized equipment can lead to inefficiencies, discomfort, and higher energy bills.

Accuracy and Compliance:

Manual J Load calculations provide a standardized and accurate method for HVAC system design. Many building codes and energy efficiency standards require Manual J compliance to ensure that HVAC systems are properly sized and installed.

Overall, Manual J Load calculations are essential for designing HVAC systems that are efficient, comfortable, and tailored to the specific needs of each building. By accurately estimating heating and cooling loads, Manual J helps optimize equipment sizing, energy efficiency, and overall performance.

?Did You Know...

The Texas Administrative Code under Texas Department of Licensing and Regulation (TDLR) addresses this topic on Codes. The standards set forth by TDLR basically convey that a house anywhere in Texas will follow the local municipalities codes. If the area has not adopted any codes than it reverts back to Texas statute and follows the International Residential Code. That code calls for a/c sizing to be determined as a result of an ACCA approved Manual J or the equivalent. The topic can be found in Title 16, part 4, chapter 75, Rule 75.100. The Texas Department of Licensing (TDLR) is the governing body which all A/C companies work under.

As of early 2024, Annaville Air Conditioning has confirmed the communities of Corpus Christi, Portland, Alice, Kingsville, Rockport are using the 2018 or 2021 IRC ( International Residential Code) when sizing a/c for both existing replacement as well as residential new construction. This is a little known (or ignored) fact by A/C contractors and especially Sales Personnel of A/C equipment and systems. Most a/c contractors believe the code to size using ACCA approved Manual J are intended for new construction only. But this is not how the rule is written. It is clear the rule is for both existing and new residences. You may confirm this by looking into the IRC code book, section m1401 paragraph m1401.3.

Code enforcement is another issue even among the mechanical inspectors working for various municipalities. However, just because an inspector or municipality is not enforcing the code does not mean the code is irrelevant.

At Annaville Air Conditioning, we believe the proper way and best way to size a new a/c system for existing and new homes is to use ACCA Manual J or an ACCA approved software for manual J. Be careful and do not accept a manual J software load if it is not one of the very few ACCA approved methods. There are many software companies putting out simplified short cut methods for Manual J. Many decades of effort by mechanical engineers have gone into the development of Manual J. These shortcut versions are not going to get the accurate results of the true and full version. Rules of thumb sizing based on square foot or other methods will very likely lead to inappropriate sizing causing comfort, mechanical issues, as well as wasting energy.

At Annaville Air Conditioning we us ACCA approved Elite RHVAC.
