Signs your A/C may not be working correctly

In the midst of this hot summer, a quitting air conditioner is one of the worst things that could happen in your home. To avoid this, not only is it important to keep regularly scheduled maintenance on your system, but it is important to recognize the signs of a failing system before you’re left in the heat. To keep you informed, here are a few signs that your A/C may not quite be functioning right.

Warm Air

This one seems pretty obvious, but if your A/C is blowing warm air, check your thermostat. If it is set to cooling, and the temperature is below the current temperature of your home, but your system continues to blow warm air, contact a professional. Your compressor may be malfunctioning, your airways could be blocked, or various other problems may be affecting your A/C’s performance.

Poor Airflow

If your unit isn’t or is struggling to blow air, there’s a good chance that a blockage is hampering your A/C’s performance. This blockage can occur in multiple places, including your ductwork, filters, or condenser coils. Be sure to maintain and replace your filters to ensure maximum airflow throughout your home. Poor airflow could also be the product of a faulty motor, so call our team if you can’t detect any major blockage in your airways.

Frozen Line

Relatedly, a frozen line is a sure indicator of a malfunctioning system. This upset can be attributed to several variables. These include low refrigerant, refrigerant leaks, accumulation of dirt on coils, dirty filters, and other restrictions of air flow from your system. View our blog here for a more in-depth discussion of frozen lines and what to do if you notice them.

Bad Odors

If you notice an off putting odor within your home and suspect it could be coming from your system, call a professional before the smell gets even worse. We will be able to isolate the cause and provide a solution as quickly as possible. UV lamps can also be a good safeguard against microbial growth that can cause unpleasant odors in your system.

Frequent Cycles

Your system should maintain relatively normal cycle lengths in its cooling process throughout the day. If you notice a spike in the frequency of your system turning on and off, it is likely indicative of a problem with your system. Contact Top Notch for a tune-up and evaluation of the health of your unit.

Strange Noises

If you hear your system start to make unusual sounds, such as grinding, rattling, or buzzing, turn off your system and contact a professional as soon as possible. These noises can indicate loose parts, faulty components, or something even more serious. Strange noises should be dealt with straightaway, and with professional care.


Another tell of a faltering system is a spike in humidity within your home. Especially in the Kansas summer, the humidity can be brutal. If your system is unable to control the humidity levels in your house, it’s time for a checkup.

All of these and many more symptoms can point to a failing unit. An important thing to remember is that through regular maintenance and tune-ups, these problems can largely be avoided and the life of your system can be maximized.
