Cellar Cooling Leak Search and Recharge

Finding where a cellar unit or a split system is losing its refrigerant, repairing the joint or coil, and charging it by weight rather than topping it off.

What the cellar cooling leak search and recharge
involves.

A cooling unit that slowly loses capacity over one or two summers, with a coil that frosts only in patches and a compressor that runs longer every month, is often short of refrigerant. Refrigerant is not used up; if the charge is low, it has leaked. On a self-contained through-the-wall or ceiling unit the loop is short and factory-sealed, so leaks tend to sit at a vibrating joint or a coil rubbed thin. On a split system the line set adds brazed joints and flare nuts made on site, service valves at the outdoor unit and often a long run through walls and crawl spaces, and that is where most leaks show up. The search starts with pressures and line temperatures to confirm the charge really is low, then an electronic detector, bubble solution and a look for oily spots at every reachable joint. Where a leak cannot be pinned down, the system can be pressure-tested with nitrogen. The repair is brazed or the part replaced, a new drier goes in, the system is pulled into a deep vacuum and the charge is weighed in, so the cellar keeps its cold instead of losing it again by the next season.

How the visit goes

Cellar cooling leak search and recharge,
step by step.

Weigh in the charge, watch the cellar pull down, and tell you the readings the unit settled at.

01

Read pressures, superheat and line temperatures to confirm the charge is low rather than the airflow or the valve.

02

Search the coil, the joints and on a split system the whole line set with an electronic detector, bubble solution and a look for oil.

03

Pressure-test with nitrogen where the leak is hidden, and show you where it is and what fixing it takes.

04

Braze the joint, remake the flare or replace the coil, fit a new drier and pull a deep vacuum that holds.

05

Weigh in the charge, watch the cellar pull down, and tell you the readings the unit settled at.

Before you call

Tell us this when you book

  1. Whether the unit has been recharged before, and when
  2. Whether you see ice on only part of the coil, or an oily stain near a joint or the outdoor unit
  3. For a split system, how long the line set is and where it runs, if you know
  4. Any recent work near the lines, such as a remodel, landscaping or a new deck

It also answers

Highest,
on the site's scale.

Finding the leak, repairing it, evacuating and charging by weight is the most involved work a cellar unit takes. A long line set or a leak hidden behind a finished wall adds hours; a leak at a service valve on an outdoor unit is the quicker end.

All service areas

Tampa BayFL · 31 areas

Salt air along Tampa Bay's shoreline pits the copper and the fins of a split condenser, and a slow leak shows as a cellar that takes a little longer each week to reach 55, so the repair pins the leak down with a detector and bubble solution before any refrigerant goes back in.

OrlandoFL · 30 areas

In Orlando's heat a cellar unit that has lost part of its charge runs longer every month while the owner of a rental notices nothing, and the repair traces the leak at the brazed joints and service valves before recharging, since topping up without a fix only buys a few weeks.

Miami / South FloridaFL · 47 areas

Hurricane winds in South Florida can shift a rooftop or balcony condenser and kink its line set, and a leak found after a storm is traced along the whole run from the condenser to the evaporator in the cellar before the system is recharged.

New York MetroNY · 75 areas

A New York split system whose line set runs through walls, ceilings and a shaft hides its leaks where nobody sees them, so the repair tests the system under nitrogen pressure section by section to find the joint that let go.

HoustonTX · 36 areas

Houston's clay soil shrinks in drought and swells after downpours, and a condenser pad that settles strains the line set where it enters the wall, so a leak repair here often starts at that bend and at the service valves beside it.

ChicagoIL · 50 areas

Road salt thrown onto a Chicagoland condenser beside the driveway and years of freeze and thaw open pinhole leaks in its coil, and the repair locates the leak and weighs with the owner whether the coil or the whole condenser should be replaced.

Los AngelesCA · 95 areas

After an earthquake a Los Angeles cellar unit that shifted in its wall sleeve can crack a refrigerant joint, and the repair looks for the oily stain that marks a leak at the brazed connections before anything is recharged.

San DiegoCA · 31 areas

Close to the San Diego shoreline, sea air finds a cellar unit's exhaust-side coil even through a vent, and a slow leak from pitted tubing is repaired and the new coil is often given a protective coating so the fix lasts.

San Francisco Bay AreaCA · 74 areas

Fog and salt air reach Bay Area condensers in San Francisco and Marin, and a cellar that slowly loses its cooling over a year is often a small leak at a corroded coil or a flare fitting, which the repair finds and seals before a recharge.

Questions about
the cellar cooling leak search and recharge.

Can you just top off the refrigerant in my cellar unit?
Adding refrigerant without finding the leak means paying for the same charge again, often within a season, and the cellar warms each time it runs low. Refrigerant only goes missing through a leak. We find and fix it first, then charge by weight.
How do I know my cellar system is low on refrigerant?
You cannot tell for sure without gauges, but the signs are a cellar that loses a little ground every summer, a compressor that rarely stops, and ice on only part of the coil. A dirty coil or a weak fan can look the same, which is why the technician measures before searching.
Is a leak on a split cellar system usually in the line set?
Often, because its joints and flare connections were made on site and move with the house. Service valves and the indoor coil are the next usual places. A careful search covers the whole loop rather than stopping at the first bubble.

Have these to hand: whether the unit has been recharged before, and when, whether you see ice on only part of the coil, or an oily stain near a joint or the outdoor unit, for a split system, how long the line set is and where it runs, if you know, any recent work near the lines, such as a remodel, landscaping or a new deck.
