My AC Is Not Cooling My House, What Should I Look For?

A Few Simple Things to Check

So the time has come when you turn on your air conditioning on a hot summer day and there is no cool air coming from your vents. This is the most obvious signs that there is a problem with your AC unit.  The task then becomes finding out the cause of that problem. Here are some questions homeowners can answer with a quick and simple check of their AC unit. to determine if they will need to call a professional for air conditioning

Is your air filter clean?

Check your owner’s manual and find the location of your air filter. Take it out and gauge whether it is clean or not. That can be done by holding it up to the light. If you cannot see through the filter, then it needs to be changed. A dirty air filter can lead to a number of different problems.

Are the batteries good in your thermostat?

Go over to your thermostat that controls your air conditioning unit and check the batteries. Try out a new pair or use a battery tester to see if the current ones are still working.

When was the last time you had your air conditioner serviced?

If you cannot remember, then it is definitely a problem. Routine maintenance is recommended every couple of years and sometimes even more frequent depending on the make of your AC unit. Check your records for the last time your unit was serviced and examine any service recommendations that was part of that last maintenance.

Is there ice anywhere on the lines or around the unit?

This will require some investigation as you will have to go outside and check the tubing that goes to the unit. Look for any signs of ice as it will indicate more refrigerant is needed. If your furnace is in basement, those lines usually run above the furnace. Check those lines for ice as well.

Are you breakers on?

Go into your fuse box and make sure that a breaker has not been tripped. If that has happened, turn the breakers back on and if there is an issue, the AC will trip them again. It is not dangerous to turn the breaker on and off.

Is your furnace switch on?

Make sure all the switches on your AC unit are turned on. The furnace switch is located on the side and it is not uncommon for a pet to brush up against it or for kids to inadvertently turn it off while playing in the basement. Most new houses are equipped with this kind of switch. In the event that you check all of those things and your air conditioning unit is still not working properly, then it is time to call a specialist. It will take a more in-depth look of your unit to diagnose the problem.
