Like any device, a/c unit require a little TLC to provide ideal efficiency. It's the A/cs that have not been kept in superior condition that tend to have a hard time most in hot weather condition.
To make certain you do not lose your cool when the weather condition heats up, we asked the professionals at Customer Reports and a/c unit pros to determine the most common problems that surface with window and central air conditioning conditioners. They highlighted eight problems to troubleshoot now. Plus, you'll find our list of top air conditioners for small, medium, and large spaces, listed below.
The No. 1 issue impacts both window systems and main Air Conditioning systems, and-- we more than happy to report-- it's the simplest to fix. Here are eight questions to ask that will help you keep your Air Conditioner at peak efficiency all summer season long.
1. Is the Filter Dirty?
No matter which kind of a/c you have, a stopped up filter limits airflow, decreasing efficiency and reducing the ability to effectively cool the air. If you have not cleaned up the filter in your window or portable a/c just recently, ensure you do and then check it periodically. For central Air Conditioner systems, examine the filter maker's suggestion for when to swap in a new one. In CR's tests, filters last anywhere from three to 12 months.
Just remember that if your system is running continuously or if you have animals, you will need to change your filters more often. "When we get calls about central air conditioning systems that aren't working well, 9 times out of 10 it's since of a filthy filter," says Stewart Unsdorfer, owner of Central Heating & Air Conditioning in Cleveland.

2. Is It Too Sunny Within?
If your window A/C is in a window that gets direct sunlight in the heat of the day, it'll have to work more difficult to cool your area. If you have an option, move it to a shadier spot. If not, keep your shades and drapes drawn throughout the day to obstruct the sun and prevent it from warming up your home.
3. Is Warm Air Leaking In? Examine the seals around your window A/C to ensure hot air isn't getting in (or cold air isn't permeating out). Reseal around your unit with weather removing if essential.
" The majority of brand-new window systems come with insulation panels to place over the plastic adjustable side panels," states Chris Regan, CR's senior a/c tester. "However to make the most of efficiency, you'll still need to utilize weather condition stripping around the perimeter of the system. And constantly use the manufacturer's setup and security hardware."
4. Is Your Window Air Conditioning Vibrating? Air conditioning unit make plenty of sound, consisting of from the whir of the fan website and the sound of the compressor cycling on and off. These sounds are typical. But if you hear a vibrating noise, it might indicate that your unit was installed improperly. Ensure it's sitting securely in the window and review the setup directions in your owner's manual to validate that no actions were missed.

5. Is the Thermostat on the Right Setting?
With a wise or programmable thermostat, you can more easily control the temperature level in your house so that it's comfortable when you exist and a bit warmer when you're not. If the temperature level seems off, make sure the thermostat isn't exposed to direct sunshine, which might cause it to sign up the incorrect temperature.
6. Are the Registers Dirty or Blocked?
If you have a forced-air heating and cooling system, frequently vacuum the registers to remove any dust accumulation. Ensure that furniture and other things aren't obstructing the airflow through your signs up.
7. Are Plants Crowding the Compressor?
The outside compressor for central air requires appropriate airflow to work correctly, so make certain there's at least 2 to 3 feet of space between the compressor and any plants or structures. There must also be 5 feet of clearance between the top of the system and any trees above.
8. Did You Remember the Annual Examination? An evaluation by a HVAC (heating, ventilation, and cooling) specialist can catch any severe problems before they worsen and leave you hot and bothered. The professional will inspect all the moving parts, as well as the refrigerant, and charge the system if needed.
