Common Air Conditioning Problems and Solutions

April 16th, 2019

If you’re having air conditioner problems, it’s probably due to a lack of maintenance, faulty installation, old age, or shoddy repairs and service procedures. Luckily, there are many things that you can fix or improve on your own.

While we don’t recommend that you open up your air conditioner (or furnace) and start poking around, this list can help you understand what the problem is and the potential DIY or professional solution that may be able to fix it.

Common Air Conditioning Problems

  1. Low Refrigerant

Low refrigerant in the air conditioning unit is like low coolant in your radiator.

Here are some of the signs that you are low on refrigerant:

If your system needs to be recharged with refrigerant, there is a leak somewhere in the refrigerant line. A professional inspection by one of our HVAC technicians can easily pinpoint the leak, repair it, and recharge your refrigerant to the optimal level. We can also perform a precision tune-up and cleaning at the same time.

We highly recommend professional AC maintenance once a year to avoid costly repairs, high energy bills, and potential safety hazards.

  1. Frozen Evaporator Coil

A frozen coil is usually the result of inadequate airflow either from clogged filters or air ductwork. A professional HVAC technician can inspect your ductwork and airflow to make sure your system is receiving the air it needs for proper operation.

No matter what kind of HVAC system you have, a clean air filter is essential for maximizing airflow and improving indoor air quality. When a filter gets clogged up with dirt, dust, hair, and other debris, it can be difficult for air to pass through. This can create all sorts of problems, including dirty coils, fans, and other components. The dirtier your air filter and HVAC system, the harder it will have to work to co0l your home properly.

Make sure you are checking your air filter every month. Simply remove the filter and hold it up to the light. If light can easily pass through the filter, it is still clean enough to use. On the other hand, if light barely passes through, it’s time to change the filter! Learn why your air filter isn’t working, how to change an air filter, and how to select the best air filter for your home.

  1. Bad wiring

Bad wiring can be the result of many situations, including age, exposure, and improper installation by uncertified technicians. Bad wiring and aging cable insulation deprives the unit of the power it needs and can also trip the circuit breaker and be a potential fire hazard if not taken care of. In fact, the National Fire Protection Association estimates around 9,000 home fires caused by air conditioners every year. About a third of the fires started with ignition of bad wiring.

Annual professional maintenance will prevent electrical issues from causing problems, such as fires and false starts. Our team of qualified technicians at Service Champions will inspect and fix wiring issues as part of our precision AC tune-up. Sign up for a home maintenance plan so you never forget about annual professional tune-ups.

  1. Outdoor unit is not working

The purpose of the outside fan is to extract the heat from your home to the outside air. If the fan outside is not working it can be susceptible to overheating and even permanent damage to the compressor. While your HVAC technician will clean your outdoor unit during annual AC maintenance, it’s a good idea to conduct some regular cleaning of your own. Learn how to clean your outside air conditioner unit.

Learn more air conditioner troubleshooting tips. If you’re still unable to troubleshoot and fix your air conditioner problem, we recommend calling out a technician immediately as to avoid more costly, long-term damage.
