Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

If something is failing or going amiss with your HVAC unit, chances are, your HVAC unit is letting you know something is not quite right. However, most of the cues come in the form of sounds that many of us may overlook. If you hear your HVAC unit grinding, squealing, screeching or squeaking, it is letting you know it needs help. I was unaware of these cues and overlooked them. It ended up costing me a lot of money in repairs. I want to make sure that does not happen to other people, so I made this website. I hope you learn how to interpret the noises your HVAC unit is making so you can get it the repairs it needs before you incur a costly repair, or worse, permanently ruin your unit for good.

4 Reasons Why Checking Refrigerant Levels Should Be On Your Commercial HVAC Maintenance Checklist

by Billie Carlson

If you own or manage a commercial building, you know that keeping the space comfortable for employees and customers is a top priority. Part of maintaining a comfortable environment is making sure that your HVAC system is running properly. That's why it's important to have a maintenance checklist for your commercial HVAC system—and checking the refrigerant levels should be at the top of that list. Here's why.

Lower Energy Costs

Low refrigerant levels are one of the biggest reasons why commercial HVAC systems don't operate as efficiently as they should. When refrigerant levels are too low, it puts strain on the compressor, which has to work harder to circulate the coolant through the system. This lowers the system's overall efficiency and can lead to premature wear and tear, resulting in costly repairs down the road. That's why it's so important to have a professional check your refrigerant levels during regularly scheduled maintenance visits.

Spot Potential Leaks

Checking the refrigerant levels during a commercial HVAC maintenance visit is a good way to spot potential leaks. A small leak can result in a significant drop in refrigerant levels, so it's important to seal them before refilling the refrigerant. In addition, checking the refrigerant levels can help to ensure that the system is properly charged. This will help to improve the efficiency of your unit, as well as improve indoor comfort.

Prevent Components' Damage

Just like your car needs the right amount of oil to function properly, your commercial HVAC system needs the right amount of refrigerant. Your HVAC maintenance checklist should always include checking your system's refrigerant levels. If there isn't enough refrigerant, your system will have to work harder to cool your building, which puts extra strain on components and can lead to damage. Checking and refilling refrigerant levels is a relatively simple task that can save you a lot of money in the long run.

Ensure Environmental Protection

From making sure the filters are clean to checking the refrigerant levels, there's a lot that goes into keeping your system running smoothly. However, one of the most important things to keep in mind is your HVAC system's impact on the environment. When refrigerant leaks, it can harm the environment. By making sure that your HVAC system is running efficiently and with the proper refrigerant levels, you can help reduce your building's impact on the environment. 

Proper HVAC maintenance involves regularly checking your system's refrigerant level. By allowing your HVAC technician to make sure that your system has enough refrigerant (and topping it off as needed), you can improve its efficiency and prevent costly repairs caused by low coolant levels!
