8 Things to Be Aware of When Your AC Needs Repairs

Like all machinery, HVAC systems can break down with use. An AC unit has various moving parts that all work together to help create the cool air it distributes. When one of these parts suffers, the entire unit suffers in efficiency and air quality.

Unfortunately, some problems go unnoticed by busy homeowners until the AC unit stops working entirely. There are ways to resolve and prevent this from happening, however. The most obvious one is to hire a professional to provide regular servicing on the AC unit.

So what should homeowners do when their home is having AC trouble? There are a few things homeowners should be aware of when experiencing AC or HVAC trouble.

The following information will help homeowners avoid costly repairs when they need AC repairs quickly. It will also help prevent expensive service fees by avoiding AC problems that can build up over time.

What Homeowners Should Look For

Things to Be Aware of When AC Needs Repairs

Spotting an AC problem is easy when it’s so far gone that it requires expensive repairs to resolve. Preventing an AC problem from worsening requires homeowners to know what to look for and how to effectively lessen the damage by calling a professional. Providing as many details as possible will help the technician narrow down the problem and fix it faster.

The following are some signs that an AC is experiencing a problem and requires a professional inspection. Some situations may be more extreme than others. Homeowners should take caution when handling any issues that involve mold, mildew, electricity, or chemicals.

  • Strange Odors – Dust, mildew, mold, grime, and debris can all cause odd smells in an AC unit’s ventilation. A professional HVAC technician can help remedy these problems quickly and safely.
  • Odd Sounds/Noises – When an AC unit makes strange noises while running, it’s usually a sign that something needs fixing soon. Loose fans can make constant noise while operating when they need replacing. Compressors get loud after continued use, requiring replacement or refurbishing to lessen the noise.
  • Inconsistent Operation – When a unit randomly shuts down without warning, it’s usually due to an electrical problem. These problems range from loose or faulty wiring to a short in an HVAC system’s circuit board. One sign that the AC unit is having electrical issues will be odd popping noises coming from it while operating.
  • Lack of Airflow – A lack of airflow from the AC unit’s ventilation is a sure sign that something is wrong. Various issues can cause this lack of airflow, including damage to the ventilation inside the home. Wear and tear on the system can also be a culprit when an AC unit has airflow issues.
  • Poor Air Quality – HVAC systems are comfort appliances by design. They provide the heating and cooling necessary to stay comfortable during the winter and summer. When the AC unit can no longer give this comfort, it’s obvious it needs to be looked at by a technician. One common reason for poor air quality is ventilation filters. These filters collect dust and debris, preventing them from entering the AC unit as it processes the air. If these ventilation filters aren’t changed regularly, they prevent proper airflow from reaching the AC unit. Another reason an AC unit may experience less cold air is a lack of coolant.
  • Inaccurate Thermostat – While not an emergency, faulty thermostats can lead to issues. Homeowners being unable to set the correct temperature can lead to discomfort throughout the home while also putting more strain on the AC unit to compensate. It’s an easy fix for an experienced AC technician.
  • Dirty Condensate Drain – The condensate drain helps keep water condensation from affecting the AC unit as it operates. As condensation builds up inside the AC unit, it will drain out with the condensate drain. If this drain becomes clogged for any reason, the water could pose a risk to the AC unit and run the risk of mold growth.
  • Signs of Mold or Mildew Growth – Mold and mildew pose a significant health risk no matter what causes them. If either gets found growing in the home, removing them quickly and fixing the problem’s source should become the homeowner’s top priority. Family members with health issues, respiratory issues, or low immune systems should avoid contact with mold. Mold grows due to excess moisture in the surrounding area, typically around leaking water pipes.

Noticing a problem becomes much simpler when the homeowner has extra knowledge backing them. Unfortunately, AC problems can crop up when homeowners least expect them.

Repair costs are easy to avoid when they involve routine wear and tear on the AC unit. Emergency AC repairs, on the other hand, can be caused by various forces and are typically expensive.

How to Avoid Emergency Repair Costs


Emergencies crop up at the worst times. When an AC emergency arises, it’s usually during the hottest time of the year when the AC is needed most.

Quickly fixing the AC problem can cost a lot more than keeping the AC running efficiently year-round. Regularly servicing an AC unit can help prevent issues that can turn into emergencies later on.

Regular servicing of an AC unit does more than giving the unit a check-up. Regularly cleaning the AC unit helps prolong the lifespan of its internal parts and increase its efficiency.

With increased efficiency comes lowered electricity bills. Keeping the unit serviced twice a year can help improve it significantly.

Another way to avoid costly emergency repairs is by having a service contract with an HVAC technician. Service contracts provide a guarantee for homeowners to receive service and repair work when they need it, regardless of the time.

Stay Cool During the Summer

With winter coming up, homeowners should start thinking ahead for next summer. Many HVAC contractors offer discounts during the winter for repair work on AC units.
