Installing a new HVAC “Heating, Ventilation and Air Conditioning” system is a great way to improve your home and lifestyle. Today’s systems combine high efficiency with top performance to give you the maximum in energy efficient savings and comfort. A lot of thought and careful planning is required before purchasing a new HVAC system. The information below is an HVAC buying guide designed to point San Antonio residents in the right direction when planning their project.

Average Cost to Replace an HVAC System in San Antonio

The average cost to install a central air conditioning system in your San Antonio home is $15,000 if you are doing a full HVAC system replacement including central AC unit and furnace. This estimation differs based on your house size and the specifications and brand of your air cooling system. But, why does San Antonio homeowners switch to central ACs?

Choosing an AC Unit for the Summer Heat

If your home location has mild summer days, then you might want to rethink if a central air conditioning system is a must. If not, then check your alternative options with your local San Antonio HVAC replacement experts. However, with San Antonio homeowners, you will most likely want to instal a central AC unit over a mini-split of ductless AC systems as summers in San Antonio are blazing hot.


Is there existing ductwork installed in your home?


The Department of Energy suggests that the optimum lifespan of HVAC systems, including a central AC unit, is about twelve to fifteen years. If your old system is below this lifespace bracket, then installing a new one may not be needed. Nevertheless, you may let your reliable local consultants to check if your existing system is still efficient or not. If not, then you might want to install a new system using the existing ductworks. Placing new ducts is unnecessary and will just increase your expenses. Moreover, newer central air conditioning models consume less energy by about 30 to 50%. 

If there are no existing ductworks in your home, installing a whole new duct system will increase the expenses. Still, if it is for your family’s comfort over the years, going for a central AC may be necessary. 


How Large is Your San Antonio Home?


Ductless or mini split-type air conditioners are powerful coolers but do not have the capacity to cool an entire house using one unit. You need several units to cool every room in your home. If your house is more than 2,500 feet, then going for a central air conditioning system is a smart investment.


How Much Budget Do You Have for HVAC Replacement?


A central air conditioning system is relatively more expensive than a single ductless AC system like a mini-split or a window-type. However, if you have the budget to replace your old ductless system to a central-type, you will understand that over the years, a central system can be more efficient and might help you to save more.

Nevertheless, you need to consider lots of factors before deciding to make a major change in your home cooling system. There are lots of benefits for switching to a central air conditioning system, however keep in mind to check the need, the existing ductworks, your house size, and your budget before proceeding. It is also best to check with expert  air conditioning installers to know your options and what system fits your home to achieve your preferred comfort level. A newer HVAC system can be a huge selling point and increase your San Antonio home’s overall value if you plan to sell it at any point. 

HVAC Installation Options for your San Antonio Home

Split System AC incorporates both indoor and outdoor equipment to condition the inside air. The main components of a split HVAC system are the outside condensing unit and an indoor air handler.

Heat pumps are one of the most efficient methods available to both heat and cool your home. It works by using the outside air to condition the inside air during both the winter and summer months.

Ductless Air Conditioners – Mini Splits are similar to a split HVAC system as they have both inside “air handler” and outside — condensing unit — components. Since these systems do not require ducts, they are ideal for small apartments or areas where space is limited for duct work.

Packaged HVAC systems provide all of the necessary components for both heating and cooling, housed in one single cabinet. They are often used in single-family homes constructed in such a way to favor a single cabinet system.

Sizing Your HVAC System

The three main areas that will dictate how your HVAC contractor sizes the new equipment are the heating and cooling requirements for your climate, the square footage of the conditioned area and the condition of all exterior walls that will interface with outside temperatures.

Sizing the unit is very important. Too small and it will work harder and use more electricity to condition the air inside your home. If you go too large, the system will cycle more frequently — more wear and tear on parts — resulting in uneven heating and cooling. During this critical planning phase of installation, it pays to have an experienced and knowledgeable HVAC contractor.

Energy Efficiency Ratings

Choosing a new HVAC system means you must decide on an efficiency standard for your new equipment. The ratings systems used to measure HVAC are:

SEER “Seasonal Energy Efficiency Ratings” measures the ratio of cooling capacity to power input; the higher the rating meaning more efficiency.

AFUE “Annual Fuel Utilization Efficiency” is a measure of how efficiently your furnace utilizes its fuel.

HSPF “Heating Seasonal Performance Factor” is the measurement used to gauge the heating efficiency of heat pumps.

High-performance equipment costs more upfront but will provide greater energy savings in the future. It is important that you weigh the benefits of both short and long-term savings.
