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

- Often people automatically assume that the system is low on refrigerant. Though that may be the case, the cause of a frozen coil could simply be that the coil is dirty. If there is a small film of dust layered over the coil, airflow is blocked not allowing the evaporator to function properly.
- The most common issue is blocked airflow. This can come from a dirty air filter, a blocked return grille, or bad flow of duct work. 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 a seized compressor. A qualified HVAC technician will be able to diagnose and offer solutions in a timely manner.
- The first checked cause is refrigerant levels. If the system is low on refrigerant the unit will not be able to meet your cooling demands. Loss of airflow in the duct system may also be a factor.
- Freon is actually a brand name of refrigerant. The two types of refrigerants used in today’s HVAC 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 be manufactured for air conditioning systems in both Tampa Bay and throughout the US. This has been pre-ordained since the Montreal Protocol was enacted in 1996. This agreement among many nations aims to decrease ozone-depleting refrigerants worldwide. Though R-22 equipment will fall under jurisdiction by 2010, it will continue to affect other products until 2020. No residential equipment that uses R-22 as a cooling agent will be manufactured after the 2010 deadline. If you are considering purchasing a new unit, ask your air conditioning professional about the new R-410A systems.
- Typically throw away air filters should be changed at least one a month, if not sooner. However, there are some factors that can be considered such as: quality of filter, type of filter, persons in the building, susceptibility to allergies, etc.
- WRONG! For an HVAC system to work properly, it should be sized properly as well. Factors that go into the sizing include size of house, shade, number of windows/glass doors, etc. An oversized unit may lead to high humidity levels causing an uncomfortable environment and an undersized unit may not be able to meet your cooling needs.
