When an air conditioner is blowing hot air instead of cool air, it’s not necessarily a sign of a major system failure. In many cases you can repair it yourself, or you may have to call in a professional. Here are a few things to check when your air conditioner is blowing hot air.

Verify that your thermostat is set to cool your home and that the fan is set to “Auto.” When the fan is set to “On,” warmer air may be circulated between cooling cycles.

Breakers

Be sure that the breakers for the system are on — turn them off and then back on if you’re unsure. A tripped breaker can shut down the compressor while still allowing the fan to circulate warm air.

Air Filter

Make sure the air filter is not dirty or clogged. A dirty air filter can reduce airflow, causing the system to shut down and blow warm air.

Outdoor Coil

Make sure that the outdoor condenser coil is not covered or blocked by furniture or other items, and that the coils themselves are not clogged with leaves, grass or small debris. Turn off the power and clean the coils if necessary. A clogged condenser can prevent heat from being properly released.

Indoor Coil

A clogged evaporator coil can cause airflow problems, leading to a frozen coil and the distribution of warm air. If the evaporator coil is accessible, it can be cleaned with a soft brush and a vacuum.

Refrigerant Level

Low refrigerant can also lead to cooling problems. Have a professional check for leaks and proper refrigerant levels.

If these steps have not solved the problem, it may be more serious, such as a major refrigerant leak or a damaged compressor. Have a professional inspect the system and determine the cause. If extensive repairs are required or the air conditioner is over 10 years old, it may be time to replace it.

Excess moisture in your home can lead to increased humidity, which makes a hot day even more uncomfortable and has negative health effects. By taking steps to control moisture in your Southwest Florida home, you can keep your cooling costs to a minimum while also protecting the health of your family.

Control Moisture In Your Southwest Florida HomeMaintain Your Air Conditioning System

One of the major jobs of an air conditioning system is dehumidification. As it cools the air, it also removes moisture from it. And if your system isn’t running properly, it will not dehumidify effectively. Have your air conditioning system inspected by a professional at least once a year to make sure it’s running properly and efficiently. Between visits, make sure that you change the air filter every few months to keep it operating well.

Size Your System Properly

If your air conditioning system is oversized for your home, it will cycle on and off frequently, not giving it enough time to properly dehumidify. An undersized system may not be able to process the volume of air necessary to remove moisture properly. When installing an air conditioning system, make sure that it is sized properly for your home, using the proper Manual J procedures instead of general square-foot estimates.

Increase Ventilation

When you are cooking, bathing, washing dishes, washing clothes or doing other activities that add humidity to the air, use exhaust fans to draw out any excess moisture. If moisture is still a problem, consider installing a separate dehumidification system.

Keep Appliances Maintained

Natural gas or propane appliances can add moisture to the air, especially if they aren’t operating properly. Have appliances like stoves, furnaces and hot water heaters professionally maintained annually, and make sure their flue systems are properly sealed to prevent condensation.

With the hot and humid climate of Southwest Florida, cooling costs are high enough without appliances and other heat sources adding to your energy costs. By taking steps to lower heat gain in your home, you can keep your cooling costs to a minimum and reduce your energy usage.

Lower Heat Gain In Your HomeUse Exhaust Fans

Activities like cooking, washing dishes, washing clothes and bathing can release excess heat and humidity into the air. Turn on exhaust fans in the kitchen or bathroom when these activities are necessary, and avoid performing these tasks during the hottest parts of the day.

Minimize Appliance Use

Many appliances like dishwashers, irons, coffee pots and clothes dryers generate significant amounts of heat when used. Avoid using such appliances until it’s cooler, such as during the evening, and turn off heat-generating electronics and lights during the daytime. Computers, set-top boxes and game systems often produce significant amounts of heat. Also, turn your water heater down to 120 degrees to save energy and reduce heat gain, and replace incandescent light bulbs with cooler, more efficient LED or CFL bulbs.

Shade Your Windows

Southern and western windows can let in large amounts of heat from the sun during the daytime. Install curtains, blinds or shades on these windows and close them during the daytime to minimize solar gain. Open the windows during cooler times, like the evening, to allow natural ventilation. Another option is to install exterior awnings over the windows or to extend the roof to provide shade, while still allowing the windows to be opened.

Other steps that you can take to lower heat gain in your home include using trees and shrubs to shade your windows and air conditioner, using light-colored materials for roofing or siding, and sealing any holes or drafts in the exterior of your home.
