How To Tell When Your AC Needs Repair

It’s important to keep an eye on your air conditioning unit to ensure it’s functioning correctly. Here are a few signs that it’s time to get your AC repaired:

  • Strange noises: If your AC is making strange noises, such as grinding, rattling, or banging, it could be a sign that there’s an issue with the motor, compressor, or other components.
  • Weak airflow: If your AC produces insufficient airflow, it could be a sign of a clogged filter, ductwork issues, or a malfunctioning fan.
  • Foul odors: If you notice unpleasant odors from your AC, it could be a sign of mold or other contaminants in the system.
  • Increased energy bills: If you’ve noticed a significant increase in your energy bills, it could be a sign that your AC is working harder than it should be due to an underlying issue.
  • Frequent cycling: If your air conditioner cycles on and off frequently, it could indicate an issue with the thermostat or another component.

By paying attention to these signs, you can catch issues early and repair your AC before they become more serious problems.

Why Do Air Conditioners Malfunction?

Your air conditioner is guaranteed to work hard during the hot summers in Arizona. When the temperature rises above 100°, it increases the likelihood of a system malfunction.

The potential for failure also increases the older your system gets and when you add in other factors, such as low refrigerant, damaged components, insufficient airflow, and electrical control failure. Whether your AC is blowing warm air or not turning on, Donley A/C & Plumbing can repair it.

Common Air Conditioner Repairs

Our licensed and insured HVAC technicians can repair a full range of problems with your central air conditioner or ductless mini-split. When your system malfunctions, hiring a professional to perform the repairs is crucial.

While there are many DIY solutions, there’s no substitute for training and experience. Our licensed and insured technicians are highly trained experts with the skills and expertise to diagnose the problem and perform the required repairs correctly.

Hiring a pro for AC repair preserves the integrity of your system and any existing warranty coverage while ensuring the repair resolves the issue and restores your comfort.

Common AC issues we fix include:

  • Failure to turn on: This can happen when the thermostat batteries run low or when the circuit breaker malfunctions.
  • Blowing warm air: Warm air blowing through registers can be caused by low refrigerant levels, a frozen condenser, or a clogged air filter.
  • Frost on the outside unit: Poor airflow, low coolant levels, and malfunctioning blowers can cause frost to form on the coils.
  • Refrigerant leaks: This can happen when hoses wear out, seals fail, or the compressor suffers damage.
  • Water leaks: Clogged air filters, low coolant levels, a blockage in the drain pipe, or a break in the condensate pan can cause your AC to leak water. 
  • Odd noises: Banging, rattling, grinding, or thumping noises are usually caused by a damaged fan motor or faulty blower or assembly.
  • Short-cycling: This common problem can be caused by thermostat malfunction, damaged sensors, frozen evaporator coils, installing an improperly sized unit, or clogged air filters.

Repair vs. Replacement

In some cases, replacing your air conditioning unit may be more cost-effective than repairing it. Our experts can help you evaluate the condition of your unit and provide an honest recommendation.

We understand the importance of delivering value to our customers and will only recommend a replacement if it’s the best option.

Some factors to consider are:

  • Age of the unit: If your AC is nearing the end of its lifespan (typically around 10 to 15 years), it may be more cost-effective to replace it rather than continue to repair it.
  • Cost of repairs: If the cost of repairs is high, and you’ve already invested a lot of money in repairing your AC in the past, it may be more financially sound to invest in a new unit.
  • Energy efficiency: Newer air conditioners are often more energy-efficient than older models, which can lead to significant cost savings on your energy bills.
  • Home comfort: If your AC struggles to keep your home cool and comfortable, it may be time to invest in a newer, more powerful unit.
  • Environmental impact: Older ACs often use refrigerants that are harmful to the environment, such as R-22. Upgrading to a newer unit that uses more environmentally friendly refrigerants can be a more responsible choice.

At Donley A/C & Plumbing, we’ll guide you through your options and help you make the best choice for your needs and budget.
