Some Common Problems Experienced With Commercial HVAC Systems


Commercial air conditioning or HVAC systems can run for years without ever experiencing a problem, however, once you notice something amiss, you want to have it taken care of as soon as possible. This is because neglecting certain repairs can mean allowing parts to break down even further so that those repair bills become more expensive, and it can mean allowing humidity to build up in your commercial facility; in turn, building materials may be more prone to mold and other damage. Note some common problems experienced with commercial HVAC systems and then note how to address them, or discuss these with a repairperson as needed.

Worn contactor

A contactor is a piece that connects the electrical wiring to the compressor, the blower motor, or the condenser fan. Contactors can get worn over time and when this happens, those parts are not getting power as they should. You might assume it's the wiring that is failing when you know the parts of the HVAC unit are in good repair but won't switch on, but it may simply be these contactors instead. An electrician can test the wiring to note if it's corroded or not and if the wiring is not the issue, the contactors are probably the culprit when a part to the HVAC system doesn't function as it should.

Refrigerant leak

One reason that a refrigerant leak may be more common with commercial HVAC units than residential units is that excessive vibration can cause damage to the refrigerant lines, so that leaks form. In a production facility or a facility with heavy trucks coming in and out of the area, there can be far more vibrations than in a residential home. If your air conditioner runs but doesn't blow out cool air, check for these leaks or have a technician note the refrigerant levels and refill this as necessary.

Drain lines

Your HVAC system will have a drain line for emptying excess condensation that forms around the parts. The drain line often gets clogged in a commercial unit because of the added dust and other debris in the air that may be common in production facilities or warehouses. When the drain line gets clogged, the drain pan under your unit will get backed up and water will usually spill over. This can cause damage to the unit itself, if other parts were to get excessively wet. If you notice any water around your unit, have the drain line checked and cleaned as needed.

Compelling and Creative Commentary on Construction and Contractors: A Blog

Welcome! My name is Frances, and this is my first blog. Whether you found me through a Google search or were passed my link by a friend, I am so glad you found my blog. I plan to fill it with a range of commentary on the world of contracting and construction work, and I hope that you find my ideas compelling and creative. I am a dog trainer, but I have always loved the world of construction. I tend to work a lot on the weekends and evenings, when my clients are off work. As a result, I have a lot of time to write during the day, and I decided to create this blog. Thank you for reading.
