REFRIGERANT LEAKS

First of all the air conditioner or heat pump does not consume Freon or refrigerant. The system is a sealed system and it does not burn or use up refrigerant to make your house cool and/or warm if you have a heat pump. The refrigerant or Freon (Freon is a registered trademark name of DuPont and is widely used to describe the refrigerant in your air conditioning system) in your air conditioner or heat pump is supposed to be locked in a hermetic system and is sealed tight. From time to time a leak can occur and the unit needs to be charged so that it can continue doing its job. As the refrigerant leaks out, the system will still cool. In fact, it actually cools too much! The indoor coil begins to freeze up because the temperature of the coil drops below the dew point. This ice reduces the amount of air flow and if left running, will turn your indoor coil into a chunk of ice that no air can flow through at all. Now your home gets hot. Before you call for service make sure you turn the air conditioning system off. This will allow the system time to thaw out. The technician will not be able to perform a leak search if the equipment is encased in ice. Once the leak is located we will be able to determine if the leak can be repaired or if the entire component will need to be replaced. If your air conditioner is older than 10 years, and uses the R-22 type of refrigerant, now would be an excellent time to upgrade. As of 2010, the supply of this refrigerant will start dwindling as it has been banned from new U.S. system production as of this year. The manufactures will still make it, but due to reduced demand, the production will slow down and price per pound will go up. In the year 2020, the U.S. will cease production of R-22 altogether. The air conditioning industry has recognized R-410a as a replacement refrigerant for R-22. It’s a great refrigerant, but it is incompatible with R-22. Unfortunately we cannot simply substitute it for R-22. Your whole system would have to be replaced. It might surprise you though, how efficient these new air conditioners are. It’s possible that you can cut your cooling costs in half with a new R-410a systems, especially if your air conditioner is 10+ years old. We have been almost exclusively installing R-410a systems since 2000, so we have a lot of experience with them. So this year before you say, just fill her up, you might want to weigh the costs of the repairs versus the age of the unit and what refrigerant it uses. This is the final year for the $1500 Federal Tax Credit. and KCPL Cool homes rebates of $650 to $850 are still available, making it a perfect year to buy efficient new air conditioning equipment!
