Air Conditioning Repair

Project Description

A homeowner in South Pasadena, CA, called us for air conditioning repair. They found the AC drain line clogged with dust, rust, and grime buildup. That resulted in water pooling inside the air handler’s drain pan. After attempting to fix the clogged drain pipe, professional help was called for. We arrived to find temporary measures had been taken, with the drain pipe cut and the water directed into a bucket that needed emptying every 12 hours. After assessing the situation, we identified that the best option was to unclog the drain through suction, then replace the PVC fittings before sealing them with weatherproofed PVC cement. So to ensure there were no leaks, we finally flushed the line with water, and everything worked as planned. All in a day’s work, and another happy client by Pioneers Heating and Air!

A clean air conditioner drain line ensures your AC never lets you down. When water flows through the air conditioning condensate drain line but does not flow out of the air conditioner into a bucket-like drip pan, it can cause damage to your home. Water will puddle and leak into your attic or crawlspace, causing irreparable property damage and expensive repairs. Regular maintenance, including cleaning the drain line, will enhance your AC’s performance and keep your home cool all year round.

What are the signs of a blocked air conditioner drain line?

Standing water near your AC unit

You may not be too concerned when you see a little water near your air conditioner. However, more than the usual amount could be evidence that something is wrong with the unit. Most likely, water is dripping because it does not drain properly due to buildup.

An always-full condensate pan

Is your condensate pan always full? That could be a sign that your air conditioner drain line is clogged. Blockage in the drain line prevents water from flowing out of the house, which can lead to mold growth in your unit. Also, look for other signs of water damage in the house, such as on the floor, near the fan, or around the AC.

Musty and moldy odor coming from your AC

Is your central air system causing an unpleasant smell throughout your house? It could be a sign of a drain line issue. Molds and mildew can worsen asthma and cause allergies, so it is important to take this seriously. For more information, you can check out our article about common air conditioner smells.

How can you prevent clogs in the air conditioner drain line?

Invest in high-quality air filters

Cheaper air filters may help you save money, but they might not thoroughly filter dust and other materials from your AC unit. Good filters can prevent dust from building up in the evaporator coils and help avoid clogging the drain line. It is typically recommended that air filters be changed every three months. However, this interval may change if you have pets or smokers around.

Regularly flush the drain line

You can prevent clogs in your drain line by flushing them with a vinegar solution every three months. Mix vinegar and water in a 1:1 ratio. You can also use just warm water. Although bleach can kill bacteria, it can damage PVC plastic pipes and break down the cement that holds fittings together. So, unless completely necessary, it is best to avoid using bleach altogether.

Perform routine maintenance

Having routine maintenance check-ups is important to keep your air conditioner in optimal condition. By doing this, you can avoid any costly repairs or replacements down the line. So have your equipment checked at least once or twice a year by a BBB-rated HVAC company. Taking a proactive approach to finding and fixing issues will benefit you greatly in the long run.
