[RFI] Ensuring an RFI free air conditioner install

[David Winarsky]

I’ve had enough of the global warming induced heat waves in Northern California and am finally being forced to install air conditioning in my home.  I’m well aware that there is an RFI risk when installing this type of appliance.  In order to mitigate that risk, I’m taking the following steps:

1.  I’ve made sure that the model does not include a variable speed motor, but is anyone aware of any issues with the Trane 4TTL6 4 ton 16 SEER Slimline AC?

2.  I’ve researched whether there is an RFI kit available from the manufacturer, but apparently according to train there is none for this model.  They are apparently only intended for models with variable speed motors.

3.  In addition, I’ve read on the list previously that I should include language in the contract to ensure it is an RFI free installation.   I asked my contractor to include this in the contract and he included the following: 

"Upon installation <the HVAC contractor> will test for RFI, if RFI is detected we will work with manufacture in resolving the issue. Any additional labor, parts, or kits to be installed will be at an additional cost to be determined at such time.”

I’m concerned that this simply means he will charge me for any additional work related to the RFI mitigation, but I can also understand that he can’t foresee what will be involved.  

Are there any additional steps others would recommend and can anyone recommend language to include in the contract that will provide more protection for myself and incentive for the contractor?
