Troubleshooting Heating and Cooling
Air conditioning has made our lives much more comfortable, and it is difficult to imagine our lives without it in our homes or businesses. It not only cools our homes, but reduces humidity and helps to clean the air in our homes when a proper filter is used. Humidity not only makes it feel hotter, it makes it harder for those with respiratory problems to breathe. Air conditioning is a life saver, literally, for many who suffer from some health problems such as asthma, allergies and many other respiratory problems. When it breaks down air conditioning repair in Dallas isn't an option for most of us, but a necessity. Before reaching for the phone to call a technician out, there are a few things you should try:
First, make sure your thermostat is set to the COOL position and that the temperature is lower than the inside temperature display. For example, if the thermostat says your inside temperature is 75 degrees Fahrenheit; your air conditioner will not cut on if you have the thermostat set at 76 or above. If the thermostat is on cool check the fan switch to ensure it is on AUTO. If the fan is set to ON turn it back to AUTO. The ON function causes the fan to run whether or not the compressor is pumping cool air at the time. Being set to ON rather than AUTO may explain why the ac is blowing warm air part of the time.
Next, check your air registers and make sure they are all open. Never block registers or the air return. Keep the area around them clear.
Check to ensure that your system is receiving power. Open your electrical panel; all circuit breakers should be in the ON position. On the exterior central air conditioning unit there will be a disconnect switch. It is usually located near the unit in a grey box mounted nearby on the house. This switch is a frequent culprit causing a central unit to shut off. If you are uncertain of the proper switch, don’t hesitate to call for professional assistance when you need ac repair in Dallas.
In cold climates heating is an essential for life and in maintaining our homes as well as our comfort. When heating fails it usually means our home becomes uncomfortable quickly. Use the following checklist to check your furnace before calling an HVAC technician out for help:
First, check to make sure your thermostat is set to HEAT and that the room temperature is lower than the temperature it is set on. For example, if your thermostat is set to 65 and your indoor temperature is 70, the heat will not cut on until the indoor temperature reaches 64 unless you adjust the temperature.
Check registers and make sure they are open. Never block registers with clutter, furniture or drapes. Always keep the area around the air return clear.
Turn the furnace fan to the ON position. If it runs there is power is going to the furnace. If it doesn't run, power may not be reaching the furnace.
Open your electrical panel; ensure that all circuit breakers are in the ON position.
