Each building is unique, requiring different solutions, and one of Stan’s experienced ‘Whole House’ Experts will be glad to help you determine which system meets your needs. A/C systems that are too small will be unable to keep your building at the ideal temperature. But a system that is too large will cost more to purchase and operate, and will be less comfortable than a properly sized system.

Stan’s will help you determine the capacity of your A/C system, but we first must know what your comfort goals are. The industry standard for determining the capacity needed for the Central Texas climate is to maintain an inside temperature of 75 degrees, when the outside temperature is 100 degrees. Your particular preference may vary. Units do this by removing the necessary amount of heat (BTUs) from your building’s air. A/C units range in capacity, from 1.5 ton systems, which can remove about 18,000 BTUs per hour, to 5 ton systems, equipped to remove about 60,000 BTUs per hour.

An equally important consideration is how much energy your system requires to remove those BTUs. All units have two energy efficiency ratings, a SEER (Seasonal Energy Efficiency Rating), plus an EER (Energy Efficiency Rating). Just like your miles per gallon ratio, the higher the rating, the less energy is consumed. By law, the SEER must be at least 13 and can go as high as 20. We will present you with a range of system options so you can make an informed decision.

Because of Central Texas’ extreme summer weather, which puts serious strain on your system and your energy bill, Stan’s recommends at least a SEER of 16, and an EER of 13. There are usually incentives to help you achieve this standard.

In addition, you should be aware of the several upgrades available. Some of the more important ones include:

  • WI-FI Thermostats controlled via Phone, Tablet, or Personal Computer
  • Upgrades to two stage or inverter compressor technology
  • Noise suppression technology
  • Warranties
  • Equipment safety controls
  • Zoning
