  • Get An Annual AC / Heating Checkup – Keep your air conditioning system operating at peak efficiency. This can end up saving you hundreds or even thousands of dollars on your air conditiong bill..
  • Change Your Air Filters - You should change your air conditioner filter every 30 to 90 days, or more often if you have pets.
  • Check the seals - If you have window or room units, make sure the seals are in good shape. A damaged seal can allow cool air to escape your home and decrease your air conditioner's efficiency.


  • Control Your Thermostat - For every degree you go below 78°, your air conditioner will use about 8% more energy. This could add up to a big diference in your utility bill.
  • Programmable Thermostats - Programmable thermostats automatically adjust how much your air conditioner runs throughout the day. They can even be set to run less when you are not at home.
  • Close Blinds and Curtains - This will help keep the heat out and the cool in, reducing the load on your a/c.


  • New A/C vs. Old A/C - Older air conditioners can cost more to repair than replace. Our technicians can help you make the best decision.
  • Energy Efficiency - Newer a/c units are usually more efficent than older models. For air conditioning in San Antonio, look for models that have a seasonal energy efficiency ratio (SEER) number of 13 or higher.
  • Long-Term Costs - Older, less inefficient air conditioners can cost you hundreds of dollars more per year.

If your system is over ten years old, you may want to consider a new unit, especially if you have a large home with high heating and cooling load. The annual dollar savings from installing a new system pays for itself in a short time.

Replacing parts in an inefficient air conditioner or heat pump will not make it efficient! This solution, while often the least costly one up front, leaves you with a running unit that will cost you more every month in utility bills.

For example, if your heat pump or air conditiong system loses capacity or if the compressor fails completely, you may want to move up to a high efficiency heat pump system rather than just replace the old compressor. Often a failed compressor is just the first of many componet failures that end up costing you more in the long run.

Finally, consider how many more years you expect to be living in your present home (planning to move soon?) the overall condition of your unit (is it likely to break down again?) and the number of expected hours of use (are they predicting particularly severe weather this season?). Planning ahead with the advice of your dealer will help you avoid surprises later.
