Is your home’s central air conditioner not cooling your house? Perhaps it’s blowing luke warm or hot air. There are a variety of things that could cause your AC to not cool your home properly. But for your convenience, we’ll categorize the problems into ones YOU can solve and ones only a professional air conditioning repair technician can solve. Does your AC blow out cool air sometimes and lukewarm air other times? Then the fan setting may be set to “ON” which just runs the fan 24/7—even when the air isn’t being cooled. Solution: Set the thermostat to AUTO. A dirty air filter reduces airflow into your AC, causing several problems: Solution: Check the air filter and change it if it looks like the filter on the right Here’s how your AC cools your house: the air conditioner’s inside unit (called an evaporator) absorbs heat from your air and then transfers that heat to the outside unit (called the condenser). But the condenser can’t dissipate heat if it’s dirty or crowded with debris.

This causes your air conditioner to struggle to cool your home. This condenser could use some cleaning. Solution: Spray the outside unit with a garden hose on a gentle setting. DON’T blast it on a high setting or you’ll bend the fins that allow airflow to cool the condenser off. Also, remove any weeds growing around the AC unit. Give it some breathing room! Here are just a few problems that a professional air conditioning contractor may need to fix: If the fan motor is bad, then the outdoor unit’s fan can’t help dissipate heat, meaning that the AC can’t cool your house. Refrigerant is the liquid that absorbs the heat from your air. When you don’t have enough, your AC can’t absorb enough heat to cool the air. A low refrigerant level means one thing: you have a refrigerant leak. Signs you have a refrigerant leak include: If you see these signs, turn off your AC and call a professional ASAP. Running the AC in this state can cause slugging in the compressor and damage it beyond repair.

The compressor is the heart of the AC system, circulating refrigerant like blood between the inside and outside unit. If it’s damaged, then the AC can’t cool your air. If there’s an issue with the compressor, then it may need replacing. Unfortunately the compressor is uber expensive.  So unless you have a warranty on it, you’ll probably need to replace an entire outside unit. Did you try solving the problem yourself?

Most people would prefer a but when you're shopping for one, it's not easy to tell how noisy a given model will be.

One reason is that noise measurements (decibel readings) are rarely included in manufacturers' product literature. Another problem is that you often don't get the chance to hear an installed unit in operation before buying it. Types of Air Conditioner Noise To further complicate matters, there are different kinds of noise that an air conditioner might make: The hum of the fan under ordinary operation Rattling and vibration of the case or internal parts A thunking sound made by the compressor when it switches onprice for a new ac unit Electronic beeping sounds when you adjust the controlsdo i need to cover my ac unit Shaking and rattling of the glass or frame in the window where the unit is installedhow big of an air unit do i need

Noise from outdoors that is no longer being blocked, since the window is no longer shut If a model gets good ratings in independent side-by-side testing for low fan noise, that won't mean much to you if the thunk of the compressor kicking in wakes you up at night. Another example is a model that gets very good reviews for quiet operation as well as for overall quality and value, but which makes a piercingly loud beep every time a control is adjusted, a detail which makes it an unacceptable choice for many consumers. Some rattling and vibration sounds are created or made much worse if a unit is not installed properly. For quietest air conditioner operation, it is essential that the unit be installed according to the manufacturer's instructions.

Tips for Reducing Noise in Your Existing A/C Window Unit If you have a window air conditioning unit and you're not in the market to buy a new one, here are some things you can do to minimize the noise it makes: First, verify that the original installation procedures have been followed properly. Pay special attention to any gaskets. If improperly installed, even a high quality, low-noise unit can rattle mercilessly. For noise originating from inside the unit: Be sure that all the compressor mounting parts are present and are properly tightened. If you identify a part that is rattling against another part, you might be able to eliminate the noise by slightly repositioning it. For vibration noise in the A/C case or the window: Be sure all the mounting screws are present and are tightened properly. If the window frame is vibrating, fill the gap with wooden shims or with foam weatherstripping applied to the A/C frame where it meets the window frame.
