If you have an air conditioner that is buzzing every few minutes, there are several common causes and fixes. Often it is simply a bad part that needs to be replaced, and the buzzing goes away. The first step is to narrow down which component is making the noise and then, if necessary replace it.… Read More »
HVAC systems such as air conditioning units need a vacuum set on the system before refrigerant is released. A good vacuum pump will remove airborne moisture and or non-condensable from the system and will boil off moisture. The deeper the vacuum, the lower the micron level, which is needed for an HVAC system to last… Read More »
Heating and cooling a mobile home can defer from a standard home. From the installation of an HVAC system to the build of the mobile home itself, some things differ from a conventional home. Installation of an HVAC system into a mobile can often be easier since they are usually not set on a slab… Read More »
Checking the AMP Draw of electric motors is important in HVAC for troubleshooting or testing a potential problem. Furnace blower motors and condensing fan motors Amp draw are checked to see if they are Over-Amping or, in some cases, Under-Amping. Every electric motor has a set Amp and voltage rating that the motor should run… Read More »
