18 Jul HVAC Vacuum Pumps are Necessities for HVAC Repair Technicians

For the individual or company that is in the HVAC repair business, HVAC vacuum pumps are a must have as part of the equipment that is used during repairs. This tool is used to prevent freeze-ups of the system, detect leaks, avoid corrosion in the system, and prevent the refrigerants from mixing. This article will go into detail about the different ways that vacuum pumps work to make heating and air conditioning systems work better.

When HVAC systems freeze up the entire system will either shut down or begin pumping out warm air because it cannot remove the heat and dispense air that has been treated for comfort. This freeze up is caused by ice crystals that form on the inside of the compressor. HVAC vacuum pumps are used to pull a vacuum on the system to prevent condensation from occurring by removing it prior to sealing off the unit. A freeze up can leave a home or business owner with costly repairs to deal with or even worse, replacement of a destroyed system.

By removing the moisture any time repairs are made that expose the interior of an HVAC unit or adding refrigerant, the chances of corrosion inside the unit is reduced. As a matter of fact if there is not moisture there is no reason to be concerned about it occurring at all. Water vapor is a destructive force when it comes into contact with metal, so removing it with vacuum pumps is the best way to deal with ill effects from corrosion.

There are times during the life of an air conditioning system when additional refrigerant must be pumped into the unit. This can occur when there has been a leak in the lines or when a new type is required for more efficient operating. Using HVAC vacuum pumps during this process will assure complete removal of the old refrigerant and that there is complete delivery of the new.

It will also remove any water vapor and prevent damage to the system.

Vacuum pumps can also be used to detect leaks of the refrigerant as well. Technicians pull a vacuum on the system and then leave it for about five minutes. After this period of time they are able to determine if a loss of vacuum occurs. If it does this is a sure signal that a leak in the system is probably. At this point discovering the source is the next step. Once the leak if repaired the HVAC vacuum pumps are used to remove any moisture before it is again sealed.

Any HVAC repair contractor is sure to tell you that they would not be able to perform their service as effectively without the assistance of vacuum pumps. Being certain that the entire system is running at its peak performance is what keeps the clients coming back time and time again, and has them recommending your company to others. This makes vacuum pumps one of the most important tools to be used when servicing air conditioning systems.
