503 925 5843

Just like any other AC units,your Trane air conditioners will probably break down from time to time.In some cases,the fix is a simple one that you can complete with a few tools and a little patience.However,occasionally,you will need to call in the air conditioning experts.Knowing when-and how-to fix the problem yourself and when to call for help can save you a lot of money in air conditioning repair bills!

The following list of three problems and basic solutions is meant to be a guide for homeowners who need to troubleshoot their Trane air conditioners.This is by no means an exhaustive list of the possible issues and solutions that your AC units can experience! If you feel in over your head, or don’t know how to proceed, always call an expert!

My Trane Air Conditioners Won’t Cool My House

If your air conditioner is new or you know it’s in good working order,the most likely problem is a tripped circuit breaker.Find your home’s circuit breaker box and reset the problem circuit.

Another common problem is the thermostat can be set incorrectly.Check your thermostat and make sure it is set to the correct temperature.If it is not,reset it to the desired temperature.

If your cooling systems are running outside of your home,but the unit inside isn’t running,put your hand up to a vent in your home.You should feel warm air coming from the vent.Check the temperature setting to make sure it is correct.If it is, turn off the unit and call a heating and cooling expert to look at the unit.Try turning the thermostat off for one to three hours,the cooling system could reset itself and solve the problem.

My Trane Air Conditioners Won’t Create a Good Air Flow

The most likely problem in this scenario is dirty air filters.Check the filter in each system component.Clean or replace the filters as is recommended in your owner’s manual.If the problem persists after you have cleaned or replaced the filters,call a heating and cooling contractor.

The system may have frozen because of a dirty coil.Check for signs of water below the AC units and feel the exterior surface of the indoor coil enclosure – if there is a problem, the surface will be cool.If this is the case, turn the unit off and contact a heating and cooling expert.You may be able to unfreeze the unit if it is off for one to three hours.

My Trane Air Conditioners are Always Running

Unfortunately,the most common problem is the thermostat is set to an extreme temperature point.Check the set point on the thermostat-is it very low during the summer or very high during the winter?Consider resetting the thermostat to a less extreme temperature.If the unit continues to run constantly,call a heating and cooling contractor.

Finding solutions to the three most common air conditioning problems can easily save you a lot of money in heating and cooling repair bills!Learn the telltale signs of problems you can fix yourself and problems that are best left to the experts,and you will be pleasantly surprised with the results.

Learn how to install a 3-way dimmer switch to control the lighting in your home and save on electricity bills with these simple instructions from Lowe’s. Installing a 3-way dimmer switch in only 15 minutes is easier than ever with this simple DIY project.

A 3-way dimmer switch is needed when you have lighting that is controlled by 2 separate switches. If you have a single pole switch, see our How to Install a Dimmer Switch video at http://www.youtube.com/watch?v=ScxeBENvcOc. When you shop for a 3-way dimmer switch, look for a 3-way icon on the packaging.

Once you are ready to install the dimmer switch, turn your circuit breaker off and label the breaker with tape or a note to ensure nobody turns it back on. Make sure the power is off by testing the old light switch and using a circuit tester on the wires. Leave the switch in the off position when you are removing it.

Install the 3-way dimmer switch by matching up the wires by color and twisting them together. Use wire nuts to secure the wires together screw the dimmer switch into the wall.

You’ll find all the tools you need to install a dimmer switch at http://www.Lowes.com/ including:

• Screwdriver
• Circuit Tester
• Needle-nose Pliers
• 4 Wire Nuts
• Electrical Tape
