Basically there are now 4 different types of air conditioners
- Basic air conditioner is 14SEER (Seasonal Energy Efficiency Rating)
- It cools, it heats. Most have a 10 year manufacturer warranty on parts, if registered. These are the least efficient, least expensive and do the job
- There is a higher efficiency air conditioner with the single stage condenser (outside unit) and a variable speed air handler (inside unit). This air handler can be set up for better dehumidification, quieter starts and stops. These are more energy efficient, 14.5 - 18SEER.
- These units are little higher energy efficient with a 2 Stage condenser and a Variable Speed air handler. When we do your heat gain calculation, your load is calculated on an average summer day of 93degrees F. This actually happens about June - September 12-7PM daily. The rest of the year the equipment is oversized. The two stage condenser runs on low speed most of the time. With lower speed operation, you get higher energy efficiency and better dehumidification. Most of these systems are "communicating" electronically and can be difficult to troubleshoot.
- This is the highest efficiency system. With a variable speed outdoor unit and indoor unit. These also would dehumidify the best. These require special mechanical training and adherence to manufacturer specifications for successful installations.
System type #2 is our #1 best seller, middle efficiency, low cost and serviceability.
