Sealed System FAQs
What exactly is the "Sealed System"?
The sealed system includes the compressor, evaporator, condenser, and the copper tubing that carries refrigerant. It’s the "engine" that creates the cold air in your fridge.
Is a compressor replacement expensive?
While it's a significant repair, it is usually much more cost-effective than buying a new high-end refrigerator. We'll provide a fixed quote upon diagnosis.
How do I know if I have a refrigerant leak?
Common signs include the fridge running 24/7 without getting cold, a slight chemical smell, or visible oily spots on the lines. Our tech can confirm this with electronic sniffing tools.
My compressor is making a loud clicking or humming noise.
Clicking usually indicates a failing start relay, while a humming noise that leads to a shutdown means the compressor motor is likely seized or failing.
Do you perform brazing and vacuuming on-site?
Yes! Our technicians carry torches for brazing, vacuum pumps for purging air, and precise scales for recharging refrigerant—all done right in your kitchen.
Can you fix a restriction in the capillary tube?
Yes, a restriction (blockage) prevents refrigerant flow. We can replace the filter drier and the capillary tube if necessary to restore the system.
How long does a sealed system repair take?
These are intensive repairs usually taking 3 to 5 hours, as we must carefully pressure test and vacuum the system to ensure no leaks exist before recharging.
What types of refrigerant do you handle?
We are certified and equipped to handle all common residential refrigerants, including R134a and the newer, eco-friendly R600a (Isobutane).
Do you provide a warranty on sealed system work?
Yes! We stand behind our technical mastery with a comprehensive warranty on both the replacement parts and our expert labor.
What is your diagnostic fee for sealed system issues?
Our diagnostic fee is $69. This fee is completely waived if you proceed with our recommended sealed system repair.
