What Is a Refrigerant Leak?

Refrigerant, sometimes called Freon, is the chemical that allows your air conditioner to cool the air inside your home. When a leak occurs, your system loses the ability to absorb and release heat efficiently. Small leaks may start gradually, but even a minor drop in refrigerant can cause poor performance, frozen coils, or compressor damage. That’s why prompt refrigerant leak repair is essential to protect your investment and maintain steady comfort.

Refrigerant Leak Repair and Recharge Services

Landry Mechanical offers complete refrigerant leak repair services. From pinpointing hidden leaks to performing a full AC freon recharge, we make sure your system operates at peak efficiency.

Leak Detection and Diagnosis

Using advanced detection equipment, our technicians locate leaks in lines, coils, or fittings with precision. Once the problem area is identified, we discuss the best repair options to prevent future leaks and system damage.

Professional Refrigerant Leak Repair

After locating the source, we seal the leak using manufacturer-approved materials and techniques. Our goal is to restore full cooling performance without compromising safety or reliability.

AC Freon Recharge

Once the leak is fixed, our team performs an AC freon recharge to bring your system back to its proper refrigerant level. This ensures optimal cooling, balanced pressure, and improved energy efficiency.

System Testing and Performance Check

After every repair and recharge, we run a complete performance test to ensure your system is cooling evenly and efficiently. We verify airflow, temperature output, and pressure levels to confirm everything is working perfectly.

Fantastic experience. Propane furnace install be another company a couple years ago. Went thru 3 igniters in the last year and was serviced by techs that were obviously not trained on this unit. Contacted Landry and a tech named Louis showed up. Went right at the unit, located the actual problem that was issue and solved it within a day, including getting a new heat exchanger from Hartford. No issues since and the whole house now has more hot water than ever due to the crud in the old unit. VERY HAPPY with Landry. Cudos to Louis !!

Very professional, honest, and quick. We replaced our 26 year old AC unit with a Heat Pump and new condenser. Landry was very professional but their quote was a little higher than some others that I had. But when I drilled into everything that Landry was including, that the other companies were not the price was spot-on. I just felt more comfortable doing business with Landry. The installers were very knowledgeable and I loved that the office sends you an email with the installers photo and names in advance. This is more than just a "nice" email, it's peace of mind knowing who is coming into your home. From the day I had my initial quote from Ed to when installers Garret, Kyle, and Dimitri completed the job was a span of 9 days. And Ed was very helpful in helping do the MassSave Heat loan. Many thanks Landry team!

If I could give Landry Mechanical 10 stars I would have. Always great service at a great price. Jose and Jack came by today and did the annual water heater flush. Also, they took time to answer my questions as all their technicians do when the job was completed. Thanks for all you guys do :)

I had Landry install a washer/dryer power and plumbing upstairs in my house. The craftspeople were knowledgeable and thorough and cleaned up well. I think it was a bit more expensive than it could have been but the job was well done. I've also used them for my HVAC service - they're very thorough and professional, and scheduling service is easy, I think because they're a big company. Again, I think they're probably somewhat more expensive than average but the service is worth it to me.

Once again we have had the opportunity to have Rosalie come to our home.
She did a checkup on our air conditioning unit and it was done well and it was a good report. Very thankful for the work that Landry and company do!

If there was a 10 star I would give it. Joe and Jack were absolutely fantastic. They arrived by 8, were done by a little after 9 and my new toilet looks fabulous. The bathroom is as clean as I left it. They took the old toilet away too. Couldn't be more impressed with these tradesmen. Thank you Gentle men!!

The entire team from initial diagnosis to pricing/sales and client service (Dave and Michael) to the install team (Garrett, Kyle, Dmitri and Don) were knowledgeable, courteous and professional. We need to replace the AC system and decided to get a new furnace as well. We were giving several options with no pressure to upsell. Our questions were promptly answered and we received updates as need. The install team was on time, explained what was happening step by step, went over scope and length of time the work would take and stuck to it. One really nice gesture by Landry was to provide window A/C units for the duration of the project. That was a lifesaver. Will use them again!

My sump hole was collapsing and I needed a substantial repair including new PVC piping out of the basement. I also wanted to add a battery back up which we never had before in case of power outage. Nick from Landry was very polite, knowledgeable and friendly. He explained our options and then returned a few days later to do an excellent job with the installation. We were very pleased and would highly recommend Landry Mechanical!
