Tips Before Calling for Heating & Cooling Services

Convenient Resources for Our South Bend & Michiana Customers

If you’ve ever come home to a hot house in the middle of summer—or a frigid one in the dead of winter—you understand how uncomfortable it can be. Though it’s probably an automatic reaction to contact your local HVAC experts at Legacy Heating and Air, Inc., there may be some simple fixes you can make to avoid a service appointment altogether.

Our Michiana HVAC team is dedicated to your safety and comfort and will never charge customers for unnecessary work. That’s why we’ve compiled a list of tips that can help you determine if the problem with your system requires a simple fix. Check them out below, and if you think the situation is beyond your capabilities, don’t hesitate to reach out to our team!

Common Simple Fixes

The following tips are for small fixes only. We don’t recommend trying to handle any other problems with your system, especially if you don’t have the training or understanding. Trying to fix a larger problem can make the situation worse and even be dangerous.

System: Air Conditioner

Problem: No Cooling

  • Check the settings on your thermostat. Make sure the temperature control selector is set below the current room temperature, and the system switch is on the COOL or AUTO position. The fan switch should be set to ON for continuous airflow or AUTO if you want the blower to operate only while the air conditioner is operating.
  • Try to get the air conditioner to turn on by lowering the thermostat to its lowest temperature setting.
  • If the air flow out of your registers seems low, check the air filter. An extremely dirty air filter can block air flow.
  • Make sure all registers are open and not obstructed.
  • Check the power disconnect switch by each unit (outdoor and indoor).
  • Check the fuse/breaker at the electrical panel for both the outdoor and indoor unit.
  • If the problem persists, please call us.
