Regular maintenance keeps your HVAC system operating at peak performance. If your HVAC system is starting to show signs of trouble, start thinking about getting much-needed repairs done, even ahead of a routine system check. Schedule a repair with a professional AC service technician right away and find out why the unit isn’t working as efficiently as it should. Here are some of the signs you should watch out for. 

Strange Sounds and Smells

Does a high-pitched whistling issue out of your unit? That’s usually a sign of a clogged filter. It could also be the result of blocked ducts. If you hear any rattling from inside, that could be a sign that you’ve got broken AC hardware to fix. Also, if there is metal clanging, that means your fan blades are damaged. And if you hear loud pops when you turn on the unit, that means you have clogged air filters.

Little to No Airflow 

Is if there isn’t a lot of air coming into your building or office from the vents, that’s another sign of a potential problem, one that requires professional HVAC repair assistance. Before you call for help, though, check if the compressor is blocked by anything. Clear the space around it and see if that makes a difference. Sometimes, clearing obstructions from the vents is enough to solve the problem. However, if the problem continues, then you know it’s not the debris or clutter in the vents or around the compressor. Check out your air filters. If they’re blocked, that could be another reason for poor airflow. Replacing them is easy enough. But if you haven’t got the proper tools, skill, and experience, it would be better for you to let a professional handle it. Other possible reasons for a poor airflow include a sluggish fan, dirty coils, low refrigerant levels, thermostat issues, and having an old or oversized unit, USA Today says. If you have cold and hot spots throughout your facility, that’s another sign of poor airflow. 

Allergic Reactions 

Do you or anyone else in your building or facility keep having allergy flare-ups? That could be caused by having a lot of contaminants in the air. That’s what happens when the quality of your indoor air doesn’t improve. While installing a humidifier will help, get your HVAC system checked first. It may be as simple as cleaning the air filter in your HVAC system. Keep in mind that you need to replace the filters regularly. Doing so will reduce any allergy symptoms. 

Repair or Replace? 

If your HVAC system is too old, though, repairs may not be enough to get you the level of performance and efficiency that you want. Also, if the cost of the projected repairs amounts to half of a new unit, then replace the system instead, Buildings says. Consult with a pro and ask about commercial air conditioning installation. Upgrading to a new unit will improve the indoor air quality in your facility and eliminate a lot of your HVAC problems.
