Air Conditioning Leak Repair Options and Replacement Parts

Refrigerant Recharge

R-22, R-410a, and R-454b systems are recharged using a digital scale to ensure accuracy. We record the exact amount of refrigerant used, and the date of the recharge for our records and the customer's reference. Our technician will then explain the best options for repairing the refrigerant leak(s).

Basic Refrigerant Leak Search

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

Pressurized Nitrogen Leak Search

We use pressurized nitrogen to locate leaks in your AC system. Our technician will use a leak detection solution to find all refrigerant leaks. You'll receive a quote for repairs once the search is complete. This process can take up to 4 hours.

Leak Seal Product Injection

This engineered solution is injected directly into your AC system. We recommend it for systems with identified 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.
