Freon leaks in your air conditioner will cost you a lot of money. Repair these leaks as soon as possible and prevent them from happening again.
In the past, a Freon leak was not considered much of a problem, because Freon was not as expensive as it is today. Homeowners would simply top off the Freon when the level went down due to a leakage. Today Freon is quite expensive, due to new EPA regulations, so it is important to keep any leaks under check.
Freon can leak from the system due to a number of reasons. The most common reasons are as follows.
Nick was great! He came right out and was able to solve the problem fairly easily. He communicated well and helped us prevent a future problem as well.

0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.

I will always call Hoffmans for my air and heat needs. They were out to my daughters house that day and fixed it. It was right before the weekend storm with below zero temps the next day. They saved my daughter and grandbabies. I could never thank them more.
Response from the owner:We are so happy to hear that we could help! Thank you for the kind review.

Got a quote over the phone. Everything was explained thoroughly. Dakota, my technician arrived and on time, was very professional and knowledgeable. He didn’t try to upsell or change anything. He did a great job. We can already tell the difference since the ducts and vents were cleaned. Would recommend an use Hoffman again in the future.
Response from the owner:Happy to hear you had a pleasant experience using Thomas Hoffmann!
The technician, Ryan, was knowledgeable and helpful in identifying the issue with our mini split AC unit. They are the second company we called after issues with the first and will be using Hoffmann again.

The technician Giovanni was excellent and on time very professional and efficient and knowledgeable of the project at hand ,gave great advice but most of all did great work đź‘Ź thank you .
Response from the owner:We are so happy to hear you had a great experience, Sam! Thank you for the review, and thank you for your business.
Your service technician was very professional and knowledgeable. And did not appear to try to give me bogus information. I truly appreciate his honesty because several other companies did not appear to be honest, obviously wasn’t honest, my gut feeling told me they were not honest and tried to get me to spend $10,000 for a problem that was much simpler to fix. I look forward to you servicing all my properties, and possibly those of the rest of my family.
Response from the owner:Thank you so much for the kind words and great review! We appreciate your support.
Whenever a newly-installed air conditioning unit has a leak, the unit may not have been installed properly. Consumers focus on finding the most ideal price for a brand-new air conditioning unit, but they may not be aware of the importance of finding the best person to install the air conditioner unit properly. Improperly attached joints may result in pinhole leaks in the unit. These pinhole leaks create slow leaks that may go unnoticed for at least one year or as long as five years after the unit is installed. Due to this, a reputable St. Louis HVAC company should be employed to install the unit.
Manufacturing Defects
Aside from poor installation work, another cause of a leaking air conditioner is a defect in components of the unit. It is possible that during the manufacturing process, some solders may have been inadequate or the unit could have suffered a puncture during packaging or delivery.
Corrosion by Formic Acid
Formic acid is an acid that forms naturally in the ground, and it can etch copper coil and produce minute cracks on it. Freon leaks caused by formic acid worsen over a period of time, which makes it necessary to constantly refill the Freon.
Unintentional Punctures In the Lines
Fastening a picture or driving nails into a wall may poke a hole on the line set of the system since the pipes of the unit are positioned along the walls and other structures inside the house.
Finding the Source of the Freon Leak
When a Freon leak is suspected in an air conditioner, an electronic leak detector is used to find the possible location of the leak. After the location is determined, a leak detection mixture is used to produce bubbles on the site of the leak.
You can do a number of things to contain the leaks. The first option is to apply a leak sealant. This is a cheap and easy method for covering any leaks on units that are between seven and twelve years old. The second option is to change the leaking part, particularly for units still covered by a warranty. Once the unit is completely drained, it will be difficult to identify additional damage unless the unit is refilled.
If your air conditioner is leaking Freon, call Thomas Hoffmann Air Conditioning & Heating LLC at (314) 471-7625 to determine the best way to repair the leak.
