Germicidal Lighting

The main function of germicidal Ultraviolet (UV) lighting in heating and air conditioning systems is to keep your air handler free of mold, mildew, bacteria, and viruses. These micro-organisms can build up and result in air conditioner blockage and bad odors in your home. The problem is caused by moisture inside the air handler.

UV lights do not clean the air; rather they clean the air handler unit. The air handler must be cleaned thoroughly before the UV lights are installed.

Some HVAC companies use scare tactics to sell UV lighting equipment by telling customers that they are breathing mold, for instance. However, JDK Heating and Air Conditioning has only sold five to ten UV lighting systems over the past four years. Every customer can benefit from UV lights, but only some people actually need them. We thoroughly inspect our customers’ heating and air conditioning systems before making a recommendation that is right for them. We never sell equipment or services that are not needed.

Typically, it takes less than 1 hour to perform a professional UV lighting installation. The usual cost quoted by other companies is in the $1200 – $1500 range, but JDK Heating and Air Conditioning typically charges only about $700 for this service.

Problem:

Customer had no heat and noticed compressor was not coming on.

Solution:

When the JDK technician inspected the customer’s system, he was able to observe the malfunction. The problem was a faulty dual capacitor and the solution was to replace the capacitor, which he did immediately since he had the part on his truck.

Compressor

Result:

The compressor comes on in heat and the system works properly now.

Time Required:

Ten minutes to locate and fix problem. Total time required including system check: 45 minutes.

Problem:

Customer had no cooling but noticed everything was running.

Refrigerant and Leak Check

Solution:

After running a few tests the JDK technician found the system low on refrigerant.  A leak check was performed with an electronic leak detector and a refrigerant leak was found on a copper tube inside the condenser.  The remaining refrigerant was removed from the system using a reclaimer and the copper tube was repaired using an oxy/acetylene torch set and solder.  The system was pressure tested, which it held, evacuated to over 600 microns of vacuum and recharged with new refrigerant to factory specifications, per instructions on inside panel of condenser.

Result:

The system now has no leaks, a complete refrigerant charge and cools properly.

Time Required:

Twenty minutes to locate problem and one hour to fix problem. Total time required including system check: 2 hours 30 minutes.

Problem:

A customer had trouble when entering a temperature change into his thermostat. When the temperature change was entered, the outside unit started, but no hot or cold air came through the ducts.

Solution:

When the JDK technician inspected the customer’s A/C system, he was able to observe the malfunction. The problem was a faulty indoor fan relay and the solution was to replace the fan relay, which he did immediately since he had the part on his truck.

Indoor Fan Relay

Result:

The A/C system fan starts and shuts off in conjunction with the outdoor unit.

Time Required:

Twenty minutes to locate and fix problem. Total time required including system check: 45 minutes.
