Ideally, your home’s air conditioning unit should be running as quietly as possible while providing you with a cool indoor environment. Yet a slight change in the sound of your air conditioning unit, even the slightest hint of a rattle or a whine, can be a telltale sign that it needs a thorough inspection.

A lot of people take their home’s heating and cooling units for granted. In any season, though, you will need your HVAC system to work properly. After all, extreme summertime and wintertime conditions would be a lot more intolerable without an efficient way to regulate indoor temperatures. It’s a good thing that you can turn to a reliable Edina heating and cooling company like Air Quality Services (AQS) whose highly trained technicians can keep your HVAC system in tiptop condition throughout the year.
