San Antonio Air Conditioning and Heating: Service, Repair, and Equipment Contractors

This local page provides resources and information about air conditioning and heating service, repair, maintenance, and installers in San Antonio, Texas. This information includes featured HVAC contractors plus a link to our handy printable grid to compare price quotes. Here you will also find sources of energy efficiency and equipment rebates, the ratio of hours of cooling and heating needed each year, and more.

About HVAC contractors

The contractor you choose will make a big impact on your satisfaction and purchase of a new air conditioning and heating system. Why? They determine the size and type of equipment for your situation and they control the quality of the installation. If you have not yet seen them, in the top navigation menu on this page you will find quick tips and expanded topics on two essential topics: how to select the right HVAC contractor and how to buy a new heating and cooling system.

Most air conditioning and heating contractors stock and install a limited number of equipment brands. Some independent contractors will order and install any brand of new equipment you
prefer to buy. Most of these service companies will repair and maintain all brands of central heaters, furnaces and air conditioners.

In addition to heating and cooling for indoor comfort and energy savings, many HVAC companies perform air quality work such as whole house air filters, dehumidifiers and humidifiers, ventilation and prevention of toxic carbon monoxide gas from your furnace. However, not all of them offer energy efficiency improvements to houses or buildings. If the service company you select does not provide conservation improvements on homes or buildings, they should be able to recommend another San Antonio company who does.

How to compare air conditioning and heating equipment price quotes

Air conditioning and heating systems are made of components or units, and these can be interchanged to yield many possible combinations of performance and efficiency. Additionally, based on the particular situation in your home or building, these components must be chosen and installed to accommodate them. For these reasons, comparing proposals, features, and prices can be more than confusing.

To help you sort through your options, use our free and printer-friendly cost comparison organizer found in the navigation on the top of this page. If you get multiple price quotes, it will save you a lot of time and headaches. This grid allows you to compare the essential features from contractor bids including: main components; equipment efficiency in SEER and AFUE; manufacturer’s and installer’s warranties; and equipment brand.

How the San Antonio climate and resources affect your HVAC needs and decisions

The San Antonio climate affects your heating and cooling loads plus the payback period when comparing the efficiency ratings of different air conditioners, furnaces or heaters. On the climate map of the U.S. with 5 zones, San Antonio lies in cooling zone 5 and heating zone 5. This location requires approximately 2803 cooling hours and 1263 heating degree-days per year. As relative guide, the average San Antonio home needs 2.2 times more air conditioning than space heating over a calendar year. Location near lakes, hills or other topographical influences can cause microclimates, so be sure to rely on actual measurements and calculations from your heating and air conditioning contractor.

The subtropical humid climate of central Texas brings many spring and autumn days in which home heating and cooling may not be needed, but a dehumidifier, whole house air filter or fresh air ventilation would make a big difference in your comfort while indoors.

Pollen, allergies and air filters in San Antonio

The pollen from certain south central Texas plants can strongly influence what type of air filter your family and your A/C system need. These change with the seasons. A few of notable examples from the San Antonio daily pollen count and forecast include mountain cedar trees from December through February, ragweed in the fall, and other types of allergy producers such as mold spores.

Local utility and conservation providers

Local utilities and availability of natural gas can determine which furnace or electric heating equipment will give you the best combination of comfort and lower utility bills. Since natural gas is available in most San Antonio neighborhoods, many consumers have chosen gas central furnaces rather than heat pumps. If natural gas prices climb faster than electricity rates, this trend might change. In situations where a heat pump makes the best choice, some of the factors that affect air source heat pumps include the average daily temperature, fluctuations in temperature, and humidity. Other local conditions such as limestone located close to the surface limit the use of ground source heat pumps.

San Antonio’s municipally owned natural gas and electric company, CPS Energy©, provides both electricity and gas to the area. They offer conservation programs, rebates and other innovative incentives. Ask your heating and air conditioning contractor if they can provide one-stop coordination for all available energy conservation and rebate programs, from local rebates and incentives to a federal tax credit.

How a whole house approach includes the “envelope” in the load calculation

If you plan to get price quotes to buy a new air conditioning and heating system, look for contractors who will insert the heating and cooling demands of the San Antonio climate along with the size and condition of your home or building “envelope” into a complex, but critical load calculation. For many reasons, a rule of thumb load calculation based only on square footage or using the same size system as the old one without verification should be avoided. This calculation requires considerable expertise and software.
