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 used and the date the system was recharged for our records and for the customer's reference.

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 used and the date the system was recharged for our records and for your reference.

Basic Refrigerant Leak Search

This is a great option for AC 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.

Pressurized Nitrogen Leak Search

Nitrogen is injected into the empty AC system. Using a leak detector solution, our technician will locate all AC system 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 the AC system. We recommend this leak repair option for AC systems that are 1-2 lbs. low on refrigerant.

Commonly Replaced Air Conditioning Parts & Products

We provide a wide range of replacement AC 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 can troubleshoot and repair any of these air conditioning parts and products.
