As the weather gets warmer, your air conditioner is working harder, and sometimes the strain can reveal problems that were formerly not apparent. If your HVAC system doesn’t seem quite right, it’s best to call for air conditioner repairs sooner than later. Here's what you should know about your air conditioner and the repair process.

Air Conditioner Repair FAQ

How does an AC work?

Inside the air conditioner is a hollow coil full of refrigerant. When this refrigerant is compressed, it gets hotter, which makes it radiate heat. When it decompresses, it gets colder and draws heat from the surrounding air. By running the refrigerant outside and compressing it, then running it back inside and letting it expand, an AC pumps heat from the inside of your home to the outside, cooling it down. The unit stops working if the refrigerant leaks out, the fan breaks so there's no airflow over the coil, or the drain that gets rid of condensation develops a clog or leak.

How should I maintain my air conditioner?

Besides repairing issues promptly, you should clean or replace the air filter every one to three months. This will allow air to flow through more efficiently, so the fan doesn't have to work as hard. Also, set your thermostat a little higher than you would in the winter, so it's closer to the outside temperature. This means the unit won't have as much work to do and won't wear out so quickly. Pay attention to any changes that might indicate a problem with the unit.

What are the signs I should look for?

Pay attention to the sound. If your AC gets louder, develops a new sound like grinding or rattling, continuously runs without shutting off, or cycles on and off quickly, call a technician. Also call for repairs if you notice an unpleasant, musty odor, see signs of water damage or mold, or the unit develops ice.

Should I wait to get repairs?

Sometimes an HVAC system develops a small problem, like a rattling sound or a minor leak. When this happens, some homeowners try to ignore the issue to save money on repairs. But if you leave a small problem, it will get bigger over time because the damaged part will start damaging the surrounding parts. Getting it fixed promptly saves you money because it will be easier, and it also ensures the unit won't break down completely. When an air conditioner isn't running efficiently, it uses more electricity, so it ends up costing you more.
