Air Conditioning Leak Repair Options and Replacement Parts

Refrigerant R-22 per lb.

This refrigerant is added using a digital scale to ensure accuracy. We record the exact amount of refrigerant used, and the date the system was recharged for our records and for the customer's reference. Our technician will then explain the best options to repair the leaking system.

Refrigerant R-410a per lb.

R-410a is added to your air conditioning system using a digital scale to ensure accuracy. We record the exact amount of refrigerant added, and the date the system was recharged for our records and for your reference. This service is followed by recommendations to repair the leaking refrigerant circuit.

Refrigerant R-454b per lb.

This A2L refrigerant is new to the industry as of January 2025, and is added to the system using a digital scale and specialized tools. Once the recharge is complete, the exact amount is recorded and our technician will explain all leak repair options.

Basic Refrigerant Leak Search

This is a great option for air conditioning systems that are low on refrigerant, but still have enough in the system to create pressure for a basic leak search. Our technicians use that pressure to search for leaks using various methods and leak detector solutions.

Pressurized Nitrogen Leak Search

Nitrogen is injected into the empty air conditioning system. Using a leak detector solution, our technician will locate all refrigerant leaks. The cost to repair any leaks is quoted when the leak search is complete. This type of leak search can take up to 4 hours.

Leak Seal Product Injection

This product is a solution that's engineered to be injected straight into your air conditioning system. We recommend this leak repair option for air conditioning systems that are determined to have micro leaks.

Commonly Replaced Air Conditioning Parts & Products

We provide a wide range of replacement air conditioning parts and products, including: Air filters, dual capacitors, run capacitors, circuit boards, contactors, compressors, fuses, evaporator coils, reversing valves, condenser motors, thermostatic expansion valves, pistons, blower motors, accumulators, condenser coils, condensation pumps, assorted relays, hard start kits, thermostats, high and low pressure switches, thermal switches, air flow switches, assorted AC drain repairs, and water safety switches. Our technicians will accurately troubleshoot and repair any of these air conditioning parts and products.
