Whole house air conditioner not cooling?

If the air conditioner turns on and the thermostat is set correctly, but the system doesn't cool down, you may have a dirty or clogged air condenser. The first step is to check the outdoor unit and clean and remove any debris or weeds that are blocking air circulation. Your gutters is the most common source of debris and weeds so you have to make sure that your gutters and roof are inspected and cleaned by a service like Gutter Cleaning Seattle WA.

A number of things can be done if the air conditioner doesn't cool down. First, make sure that the thermostat settings are cold and that the desired temperature is lower than what is currently in this room.

Next, try changing the batteries if that doesn't work, especially if the thermostat screen isn't working properly. Learn what to do here if your thermostat doesn't reach your desired temperature. If your thermostat doesn't work at all, we can tell you what that means here. Your air conditioning system may include an air filter located inside or around the indoor air handling unit.

The filter traps dirt, dust and other particles suspended in the air when they enter the air treatment unit. It keeps system components clean and running more efficiently, and can also help keep the air in your home clean. A dirty air filter can block air flow and reduce the cooling of your home. In more extreme cases, it can cause the system to shut down completely.

If the air conditioner is blowing cold air but it doesn't cool the house, there could be a leak in the house to the outside. Check that all windows and doors are closed. If the air feels colder than room temperature, it may not actually be the desired temperature and it could just be the fan that blows. Perhaps the most common cause of air conditioning problems are clogged filters.

Dirt, pet hair, pollen, and dust can clog filters. If the air conditioner works but doesn't cool down, check the thermostat settings. Someone may have changed the temperature or the settings of the thermostat fan. Make sure it is set to cool and not to ventilate.

If all the settings look correct and you're still having problems, then you should continue to the next step. The air conditioner may not cool down due to a clogged or dirty air filter. Locate your air filter and visually inspect it. If you notice that you have a decent amount of dirt or debris, then change your air filter.

The indoor air controller also has evaporator coils that remove heat from the air. The inner coils can get dirty and clogged if you don't change the air filter regularly. We do not recommend that you try to clean the inner coils, as they are more delicate than the outer coils. Another problem that can cause the air conditioner to work but not cool down is the freezing of the evaporator coil.

We have an article on how to fix a frozen air conditioner line. But in short, turn off the air conditioner if you have a frozen air conditioner. Let your system run on a fan only until the coil is no longer frozen. In the meantime, follow our tips for fixing a frozen air conditioner.

If the air filter appears to be clean or the air conditioner still doesn't cool the house after replacing it, continue to the next step. There are a wide variety of reasons why you might find your air conditioner working, but not dropping the temperature in the house. If the cables inside the disconnect box are loose, damaged, or burned, the air conditioner unit will not be able to cool your home. This means that an adjusted air conditioning system will operate normally whenever the temperature is below 93 degrees.

Air conditioners work in part by removing moisture from the air (through condensation), and that moisture must go somewhere. Before assuming the worst, review this quick and easy list of common sources of malfunctions that often decrease air conditioner efficiency. If the central air conditioner still doesn't cool your home after confirming that the air filter is safe, you'll need to look a little further to find the source of the problem. If your ducts are cracked or lack proper sealing, the air conditioner may be dissipating inefficiently around you without you even realizing it's there.

As in any profession, there are many certified technicians with incredible knowledge who will work to ensure that your air conditioning needs are met and will do so at a fair price. Typical split system air conditioners have many moving parts, including an indoor air treatment unit (oven or fan), an evaporator coil, an air filter, a thermostat, and a copper tube (refrigerant lines) that connect the indoor and outdoor units. There's a good reason homeowners spend a significant amount of money on efficient air conditioning. As the leading commercial and residential HVAC repair company for Livermore, Dublin and Pleasanton, Superior Mechanical can do it all, from heating and air conditioning services to boiler services and plumbing services.

Warm indoor air passes through the evaporator coil, where heat energy and moisture are removed from the air. Solving refrigerant leak problems is an air conditioner repair that must be performed by a trained HVAC technician. . .
