Hello Derek, The applicable standard may depend on the intended use of the device. For many applications of HVAC equipment, I am going to make an argument for EN 55014.
EN 60335-2-40 is the Safety of household and similar electrical appliances, Part 2: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers. Its scope states "Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard." HVAC where laymen will set the temperature, change filters and such would fall under this safety standard. If EN 60335-40 is the applicable safety standard, then EN 55014 would be the corresponding EMC standard. Its scope states that it "applies to the conduction and the radiation of the radio-frequency disturbances from appliances whose main functions are performed by motors and switching or regulating devices, unless the r.f. energy is intentionally generated or intended for illumination." Putting these two together, I would lean towards stating that EN 55014 is the applicable standard for HVAC equipment with the exception of industrial and heavy commercial units.

From: Derek Walton [mailto:[email protected]] Sent: Saturday, March 06, 2010 12:28 PM To: [email protected] Subject: HVAC Product standard Morning folks, I have been asked by a client to test a piece of HVAC equipment, and his proposal is for EN 61326. While I admit there is some interpretation where this could be seen as applicable, I was wondering if there were now specific HVAC equipment product standards published.
