It’s a common question we hear from California homeowners in summer, “Why isn’t my air conditioner cooling my home!?”We’ll help you troubleshoot this annoying problem. To do that, we need to ask you a few questions to help pinpoint the cause of the problem.So our first question is…A dirty air filter blocks airflow to the air handler.  However, this is caused by a refrigerant leak, which you’ll need a professional’s help to find and fix.If no air is coming through your supply vents and the AC unit isn’t working at all, follow these steps:1) Check your thermostat temperature— Make sure you’ve set the temperature setting at least 5 degrees below your room temperature.2) Make sure the thermostat is set to “Cool”— Seems simple, but you never know if one of your family members (or the dog) accidentally set it to  “Off” or “Heat” by accident.3) Check the air filter— If an air filter gets too dirty, it will completely block airflow and freeze the inside unit.

Change the air filter if it’s dirty. Here’s our guide on selecting the right home air filter.4) Check that electricity is going to your air conditioner—This means checking service switches that are:If any switches are set to “off”, then there may be a problem with your air conditioner.For example, an AC with a water sensor switch will shut down if it has a clogged condensate drain line and water spills into an overflow pan. Long story short, this means the your AC shut down to prevent water damage to your home.Also, your AC may also be overheating, causing the air conditioner to pull in more electricity than the circuit breaker can handle. So the circuit breaker cuts power to your AC. If the circuit breaker keeps cutting power after your AC runs for awhile, don’t ignore it. It’s trying to tell you something is wrong.Call a professional to figure out why this is happening.If you need help finding any of the switches we mentioned, ask our experts for help.Get quick AC repairs in California If your AC still isn’t cooling your home and you live in the the East Bay, San Jose, or Sacramento areas, contact Service Champions North for an AC repair.

How do you troubleshoot a Trane AC unit? To troubleshoot a Trane AC unit, you must first identify the specific problem. Common problems with Trane AC units include incorrect thermostat settings, lack of airflow, frozen oil and tripped circuit breakers. Setting the thermostat is necessary before running any controllers in your home. how much does it cost to run ac unitBefore considering that the problem is a clogged indoor filter, check your coil system to see if it is frozen or dirty.how much does an ac unit cost to run What is a Trane Chiller?ac unit not working well What are the advantages of buying a Trane appliance over other brands? What are the benefits of a Trane CleanEffects air cleaner? If your Trane AC unit lacks airflow, start by checking the system filters.

Most Trane AC units are designed for vacuuming or cleaning. The filter also allows easy slide-out cleaning. Check and clear the clogged filter to allow more airflow. If there is water under the unit and a cold exterior surface on the enclosures of the coil, shut down the system thermostat for a few hours. In some cases, the system requires the unit to defrost and restart to fix a frozen coil. If the heating system comes to a complete halt, begin by checking the A/C, HP or air handler circuit breakers. Modern machines can fail as a result of overloaded circuits and older wiring. It is necessary to check and reset your circuit breaker in the event your system fails completely. If the system fails because of a faulty home breaker box, it is necessary to contact professionals for assistance. Learn more about Appliances How can you troubleshoot a Trane heater?

Central air conditioning system usually have electronic control system that indicate the type of error or failure in the system.Electronic controls are becoming more sophisticated and greatly help in troubleshooting of big system. There are electronic systems that can be remotely controlled or monitored and they are usually installed in mission critical type of environment. Some of the possible causes of failure in the system are listed in the air conditioner troubleshooting Go To Air Conditioner Troubleshooting Guide 1 Back To Air Conditioner Troubleshooting Home PageNow that we have seen how an air conditioner does the work, let's look at the mechanics involved. We can see that there are two main systems in a roof top air conditioner, the sealed refrigeration system, and the air handling system. In addition to these systems, there is, of course, the control system (thermostat and fan switches).For the sealed system, all brands, Coleman, DuoTherm, Carrier, Intertherm, and others, work the same, using the basic principals of refrigeration.

In the sealed system, the main component is the compressor- which, by itself, is not serviceable, but there are some components that are external to it which are serviceable. For now, let's look at the most common and easily repaired problems. The one major compromise that roof top air conditioners all have in common is the fact that they all have to route both the return and supply air through a standard 14" by 14" cutout in the roof. This is even more amazing when you realize that the average 13,500 btu air conditioner has just over 1 ton of cooling capacity- a 15,000 btu model is around 1 1/4 tons. A motor home or large trailer that has two 15,000 btu air conditioners has 2 1/2 tons of air conditioning- or enough capacity for many houses. The two most common complaints are "Not cooling enough" and leaks. Let's look at "not cooling" first. Not blowing cold air. The first thing to determine is if the compressor is coming on. If it isn't, it is likely a control problem with the thermostat or relay board (if you have a wall mounted thermostat).

If the compressor is coming on, then you need to look into the airflow of the unit. Whether or not the compressor is coming on, you need to check the voltage. Like every appliance on board, the air conditioner needs adequate power to operate. If the voltage is 110 volts a.c. or below, the effectiveness of the unit will start to suffer. After verifying correct voltage, we need to look at how the air conditioner does it's job- it requires adequate air flow over both the inside (evaporator) and outside (condenser) coils. If the air filter is clogged refrigerant will not be able to pick up enough heat from the inside air, and if the condenser coils are blocked by leaves, it will not be able to give off enough heat to the outside air. Most RV rooftop air conditioners have washable filters, which can be vacuumed or rinsed off in a sink to clean. If you are in summer weather where the air conditioner is running 24 hours a day, the filters should really be at least vacuumed once a week. Note that if the filters have been neglected, the evaporator coils probably need cleaning as well.

These can be seen when you remove the air filters, and possibly the inside air box. Likewise, the condenser coils can be seen after removing the upper shroud. Note that some air conditioners draw air in from the back, and some blow air out the back. You will need to determine which your is, or just check both sides of the condenser. An unavoidable drawback to being able to mount an air conditioner in a 14" by 14" roof vent cut out is that both the supply air and the return air are in very close proximity to each other. This can be a problem if the two are not sealed well from each other- if the cold supply air can recirculate into the return side, the evaporator coil can easily freeze up, plus that is cold air that is just going to waste. Note that this is normally more of a problem with ducted type air conditioners than the standard exposed air box type, but it is something that you need to be aware of, in all cases.A fairly easy way to check is to simply, carefully put your hand into the return air duct and feel for cold air.
