Unexpected AC Repair: What to Do Next - ProSkill's Quick Guide

If an unexpected AC problem comes up during the hot months, it can be a big problem for you and your family. 

Let’s talk about some of the common causes of AC issues and you can fix them yourself.

Common AC Problems And Possible Solutions To Fix Them

If your AC is having one of these minor problems, you may be able to fix them yourself. More complex issues should always be left to an HVAC professional to handle.

Hot Air is Coming From the Vents

If you’re trying to escape the summer heat, having an air conditioner that only blows hot air can be frustrating. But luckily, there may be a solution to the issue.

Check your thermostat’s settings and batteries and ensure they are good and set correctly. Replace the batteries and reset the thermostat if necessary. If your AC unit is still blowing hot air then check to make sure your circuit breaker hasn’t tripped. If it has, restart it by switching it on and off again.

Odors & Sounds

An odd smell coming from your AC unit may worry you. However, if this smell starts and stops quickly it is most likely due to your air conditioner not being run for a long length of time. This can be avoided by cleaning your unit prior to starting it back up after the winter season. If you smell gas or burning coming from your AC, make sure to speak with an HVAC professional.

Strange sounds that come from your AC unit can actually signal a more complex, deeper problem with your system. This should not ever be ignored as the problems may grow worse.

Leaking Unit or Components

Humidity is removed from the air as your AC system runs and cools down your home. If you’re noticing leaks on the inside or outside of your unit, it typically means that it needs to be serviced. Even though there are a variety of reasons that your AC unit may be leaking, one common cause is a clogged drain.

Make sure that your internal components are working properly. This means that your condensate pump will be removing water and your condensate drain line will be clear of all clogs and blockages. If they need to be cleaned, do so when you are done inspecting the unit.

Unit Isn’t Kicking On

Oftentimes an AC system that doesn’t want to turn on has a quick solution. Follow the above steps we laid out for when an AC is blowing hot air. If your unit still refuses to kick on, call a pro.

Coils are Frozen

A coil may freeze when debris and dirt prevent warm air from reaching the coil.

Unplug your AC system from its power source and let the coil thaw. Inspect all internal areas of your unit and rid it of any dirt and debris. Once the unit has been cleaned, air should be allowed to flow to the coil again.   

Cycling On and Off

Damage to the compressor and fan can be caused when your AC system is turned on and off frequently. This is especially when done over a short period of time. This is because the components need to work hard each time the AC unit is turned back on.

This is a job that a professional should handle because acid build-up can occur and cause you harm.

Airflow is Weak

If you are noticing hot and cold drafts in your home, you most likely are dealing with weak airflow. Typically weak airflow is due to leaking ducts, blocked vents, low refrigerant, or dirty air filters.

If you think that your thermostat may be faulty, recalibrate it. Also, ensure that all vents are open and not blocked by furniture and appliances and that all air filters are clean or new.

Repair or Replacement: Which Do You Need?

Some AC issues are past the point of repair and need a new AC system to remedy the problem. Here are a couple of things to keep in mind when you are thinking of having a repair or replacement.

The Age of Your System

Every appliance, including AC systems, have a service life in which they will function properly. When your AC unit is past its service life you’ll begin to have large problems and may need a replacement. Modern units last 15-20 years whereas older models last 10-12 years.

Energy Costs & Consumption

If your energy bill begins to climb, it may be because your AC unit is taking up extra energy and working harder. Have an HVAC professional take a look and they will be able to tell you if it’s something that can be repaired or if you’ll need a replacement.

Comparing the Costs of Repair vs. Replacement

You may be wondering which method will save you money. Repairs can vary depending on the type of AC system you have and range from $100-$900 while replacements can range from $2,000-$15,000.
