It depends on the size of your home, whether you require a gas or electric system, the SEER rating, your budget, and your preferred brand.

SEER stands for Seasonal Energy Efficiency Rating, defined by the Air Conditioning, Heating, and Refrigeration Institute in its standard ARI 210/240, Performance Rating of Unitary Air-Conditioning and Air-Source Heat Pump Equipment.

Simply put, the higher the SEER rating, the more efficient the unit/system will run, which will save you money in the long run. However, a higher SEER unit/system will cost a bit more upfront.

You may want to try these fixes before contacting us:

• The FIRST thing you should do is check your filters. Clogged filters can cause your air conditioner to shut down.
• Check your breaker(s) and the batteries in the thermostat.
• Ensure nothing is blocking the air handler in the attic.
• For good maintenance, turn OFF the system at the breaker and wash out the exterior coil. (FYI: When mowing, avoid discarding grass into the unit as this can clog and damage it.)
• If the problem persists or you are not confident completing these checks, call us. We are always happy to help!

We recommend replacing your filters every 30 days during our hot Texas summers. Use a pleated filter (not too cheap, but not top-of-the-line either). This is a very easy and cost-effective way to maintain your system.

This depends on each dealer and supplier, as different deals and incentives are offered. Everyone has a preferred product. We primarily recommend Comfortmaker because it is the brand the owner of Cool Climate, Carl, has installed in his own home, which makes it a logical recommendation.

Yes, some products are made better than others. However, sometimes you are paying for the luxury of a particular name. Research which brands have lesser-known affiliated brands, as these "off-brands" can offer excellent quality at a lower cost. Tip: Just like with cars, consider whether you mind paying more for brand-name parts and supplies, as these costs can add up over time.

The cost has dramatically increased due to a rise in the price of R-22, the most common Freon refrigerant in older air conditioning systems. Prices for R-22 Freon have more than doubled this year and have increased by more than 500% since January 2003.

In January 2010, the EPA banned the manufacture of new air conditioners using R-22 due to its ozone-depleting effects. While the use of R-22 was not banned, it can only be produced or imported for servicing existing equipment. Consumption must be reduced by 90% by January 2015 and by 99.5% by January 2020. Production of R-22 will be banned starting January 2020. In January 2012, the EPA proposed a significant reduction in R-22 production and distribution, leading to sharp price increases this year. Owners of systems containing R-22 should expect costs to continue rising dramatically over the next 5-10 years as supplies diminish.

As a general rule, a good 12 inches of loose insulation is recommended to provide better savings on your utilities.
