When to Call for AC Repair – Key Warning Signs

5 min read

Nobody wants their air conditioner to fall sick during the hot summer months in Texas. The heat in Van Alstyne is not just uncomfortable; it can even be dangerous. Being able to catch problems early on is massively important. At Airview AC, we have seen it all–noisy compressors, putting the system down for good, and small symptoms converting into big (and dreaded) headaches. So, how do you know when to call the professionals? Let us sort through this. 

Weak Airflow or No Airflow

The first red flag your air conditioner may throw is poor airflow. If you can feel weak airflow or no airflow at all while standing by the vent, it is time to check your AC system carefully! There could be something wrong with the blower motor, ductwork issues, or even compressor problems. Any of these is a potential problem that is best left for an expert technician to attend to before it leads to complete failure. 

Air Is Not Blowing Cold

That is where big trouble begins. If your air conditioner is running, but the air coming out of its vents is not cold, you could be looking at any refrigerant problems, leak, low charge, or perhaps the outdoor unit is facing issues. Regardless, your AC system is choking under this operation and consuming more energy to keep your home cool (or at least trying to). Call in the pros for this kind of trouble. 

Odd Sounds from Unit

Your air conditioner should hum quietly in the background. If it screeches, bangs, clicks, or buzzes, this clamor is a plea for help. These noises could be signs of anything from looseness, electrical problems, and failing motor bearings. Fixing these issues quickly will give you a fighting chance against incurring severe damage later. 

Moisture or Leaks Around the System

Finding moisture or puddles near the indoor or outdoor unit is never a good sign. While it could be a clogged drain pipe, it can also mean a refrigerant leak, which is dangerous for your AC. Either way, that's a job for the pros. Don't let it wreck your walls, floors, or system. 

Unpleasant or Strange Odor

Is there a musty or burning smell coming from the vent? That may mean mold in the system or some electrical problem. Mold isn't just an inconvenience. If it's blowing through your home, it's a health hazard. Burning smells, however, might mean wire insulation is overheating. If there's anything pungent hanging about, it's time to call for a pro to take a look. 

High Energy Bills All of a Sudden

If your energy bill doubled and you didn't throw a party with the thermostat set to 65, your AC might be to blame. An abrupt spike in cooling costs usually translates into your air conditioner running longer or harder than expected due to some internal issue, refrigerant leaking, compressor breakdown, or a clog somewhere.

Thermostat Malfunctions

Sometimes, it isn't just the Air Conditioning that goes wrong. If the temperature at your home doesn't get to the one set at the thermostat, or different rooms feel drastically different, chances are it is because of a wiring issue or a faulty sensor. An estate or technician can quickly check your thermostat and tell you what needs to be replaced or repaired.

Over-Cycling and Bad Distribution

A few other symptoms to check for and which require help from professionals are: 

  • Your AC turns on and off too many times within a short period.

  • The rest of your house seems much chillier (or hotter) than the rest of the areas.

  • You hear loud clicking for each cycle when it's turning on or off.

  • The outdoor unit never seems to stop running.

  • Even if the system is on, the air always feels humid.

Any of these conditions would indicate that your system is overburdened. In cases of neglect and improper sizing, it could malfunction.

When to Call the HVAC Specialist

Don't ignore such signs. Call an HVAC technician to your house right away. You know how repairs can be delayed, but it's most likely that things will cause damage to the equipment to worsen — and so, too, the bills. A trained HVAC technician will surely and undoubtedly point out the cause of the problem and bring your unit back to operational condition without groping in the dark or risking any further damage.
