Frequently Asked Questions
What are SEER Ratings?
- SEER stands for Seasonal Energy Efficiency Ratio.Â It is the total cooling of an air conditionerin Btu during its normal annual usage period for cooling divided by the totalelectric output in watt-hours during the same period.Â All manufactured equipment is required to bea minimum of 13 SEER.
How do I get the Energy Star Rebate?
- Â To qualify for the Energy Star Rebate you have to purchase aunit that qualifies according to the government stipulations.Â These units are high SEER systems.Â For more information on how the tax creditworks and their FAQS, click the following links.

- Â Often people automatically assume that the system is low onrefrigerant.Â Though that may be thecase, the cause of a frozen coil could simply be that the coil is dirty.Â If there is a small film of dust layered overthe coil, airflow is blocked not allowing the evaporator to function properly.Â
- The most common issue is blocked airflow. Â This can come from a dirty air filter, a blocked return grille, or bad flow of duct work. Â There may also be a leak in the duct system, losing vital airflow.
- This could be something as simple as a tripped float switch to aseized compressor.Â A qualified HVACtechnician will be able to diagnose and offer solutions in a timely manner.
- The first checked cause is refrigerant levels. Â If the system is low on refrigerant the unit will not be able to meet your cooling demands. Â Loss of airflow in the duct system may also be a factor.
- Freon is actually a brand name of refrigerant.Â The two types of refrigerants used in todayâ€™sHVAC systems are R-22 and R410A, though R-22 is no longer in production.
- As of January 1, 2010, R-22 equipment will no longer bemanufactured for air conditioning systems in both Tampa Bay and throughout theUS. This has been pre-ordained since the Montreal Protocol was enacted in 1996.This agreement among many nations aims to decrease ozone-depleting refrigerantsworldwide. Though R-22 equipment will fall under jurisdiction by 2010, it willcontinue to affect other products until 2020.Â No residential equipment that uses R-22 as a cooling agent will bemanufactured after the 2010 deadline. If you are considering purchasing a newunit, ask your air conditioning professional about the new R-410A systems.
- Typically throw away air filters should be changed at least onea month, if not sooner.Â However, thereare some factors that can be considered such as: quality of filter, type offilter, persons in the building, susceptibility to allergies, etc.
- WRONG!Â For an HVAC systemto work properly, it should be sized properly as well.Â Factors that go into the sizing include sizeof house, shade, number of windows/glass doors, etc.Â An oversized unit may lead to high humidity levelscausing an uncomfortable environment and an undersized unit may not be able tomeet your cooling needs.
