AC Blowing Hot Air?

One possible reason that HVAC systems blows warm air is dirty filters. The system is producing cold air but it cannot flow through the ductwork. Clean air filters protect your equipment and help it perform properly. HVAC systems work harder as the outside ambient temperatures approach triple digits and may not cool as effectively as you desire.

You should also verify that the outside unit is running. If the outdoor unit is on, ensure that leaves and other debris are not obstructing the airflow. An air conditioner that blows warm air can be a sign of insufficient refrigerant. Only licensed air conditioning repair technicians can replenish HVAC coolant.

HVAC Care After Storms




After the storm passes, many people are eager to resume their normal daily activities. However, if your AC or furnace unit has gotten some kind of debris in it, it’s wise to hold off until you or a professional can perform a thorough inspection of the unit.


You might wonder what things to look for during your inspection of your HVAC system following a storm. First and foremost, check the surrounding area to ensure that your unit is not sitting in water.  Once you ensure that the unit is free of water, it is essential to inspect it for other debris. Once debris is removed, check over the unit for damage. This may include anything from loose screws and panels to missing components.

Summer HVAC Maintenance Steps

  1. Check your air filter. During periods of heavy cooling system use, the filter should be inspected monthly to make sure it has not become full of contaminants. You may find it necessary to replace it sooner than the 3-month mark during these times, so have a replacement ready just in case.
  2. Inspect all registers and return air grilles in your home to ensure they have not been blocked or shut. These vents should never be blocked, as doing so will restrict airflow through your HVAC systems, which could create performance issues and system overheating.
  3. Move all carpets and rugs, furniture, and other items away from vents. Check to see that vent louvers are open; if you wish to shut off cooling to unused areas of your home or building, never close more than 20 percent of the structure’s HVAC vents. If you have many unused areas, consider investing in a zoning system which will allow you to reduce energy waste while facilitating proper HVAC system performance.
