What to Do If The AC is Blowing Warm Air?

Nothing is more uncomfortable than summer heat without a working central air conditioning system. While many issues require the assistance of an AC maintenance professional in Vaughan, there are a few that homeowners can resolve themselves.

What to Do When AC is Blowing Warm Air?

If your air conditioner isn’t blowing cold air, it’s likely because you haven’t set the thermostat to “cool” or the fan system to auto. Ensure the temperature inside the home is at least five degrees cooler than the temperature outside. If everything is in working order, your air conditioner should start blowing cool air into your home.

Debris and dirt are kept out of your HVAC system with air filters, including the air conditioner and furnace. Over time, the filter might become clogged with dust, debris, and pet hair. If you have allergies, asthma, or pets, you should change it more frequently.

  • Keep the Outdoor Unit Clean

Dirt and debris on the external section of your air conditioning unit can have the same effect as a dirty filter on its ability to chill your home. The condenser is an outside unit that contains cooling tubes, fins, and a fan. Make sure to remove and pull out the disconnect plug from the disconnect box, or turn off your main breaker panel’s AC switch before cleaning your condenser.

What Should you Do If the AC is Cooling but not Sufficiently?

  • Check Air Registers

Air conditioning repair professionals in Vaughan suggest that you need to ensure your air registers (vents that blast cold air into your home’s rooms) are open and clear of obstructions. These might become blocked, or dust can accumulate over time, limiting ventilation. Remove the registers with a screwdriver and inspect them for dust and obstructions.

  • Clean the Filters

Dust buildup in the filters is another cause of the blockage and restricted airflow. Although these filters should be changed or cleaned every 3-4 months, many homeowners only do so once a year or less. The return vent, which removes air from your home to be cycled through the cooling system, and the furnace or air handler itself are the two key areas to examine. Check both of these filters and see whether they need to be replaced or cleaned. You can also get help from our air conditioning repair professionals in Vaughan.

The interior unit and evaporator coil can freeze because of refrigerant issues. Check for frost buildup on the copper lines leading to the indoor evaporator coil if you have limited or no airflow. The coil is likely to look lik one gigantic ice cube if ice develops on these lines.

Even an appropriately sized AC unit can struggle to cool your home on a scorching day. Still, if you’re having difficulties cooling your home regularly, you may have an undersized system. In any case, it’s time to seek professional assistance to resolve your AC issues.
