With hot temperatures approaching, now is the best time to schedule air conditioning unit repairs. Is yours up to the task of running all summer without breaking down? To make sure, switch it on early to check for signs it needs repairs.

C & S Heating & Cooling in Wentzville, MO, provides the best HVAC repairs and maintenance in St. Charles County, and their professionals explain symptoms of an air conditioner that needs service:

• Weak Airflow: Turn your air conditioning unit on full blast — or what should be full blast. If the airflow is much weaker than it should be, your unit could have a failing compressor. If the limited air circulation applies only to certain rooms in your home, your ductwork probably needs to be cleaned.

• Strange Noises: No equipment is completely silent, but some noises are more worrisome than others. In an air conditioning unit, the most problematic sounds are grinding and squealing. There are many possible causes, so the safest action is to call an experienced HVAC contractor for an inspection.

• Odors: The most common smell associated with air conditioning is mold, which is especially problematic for people with allergies. If you notice a moldy scent coming from your air conditioner’s vents, schedule ductwork cleaning and drainage of the condensate line. A more disturbing smell, however, is a burning or smoky stench. If you smell anything pungent after turning on your unit, turn it off immediately and have it inspected by an HVAC contractor.
