Restaurant Ceiling Leak From the Unit Above in Raleigh

What the customer reported

A main drain was reported leaking into the retail space below a unit in the 27605 area of Raleigh.

What we found and did

The leak was in the vent stack piping coming from the unit above and extending into the restaurant area below. It was located between flooring sections and at a 3-inch 90-degree fitting in the restaurant ceiling. Nick, Alex, and Chris identified the leak locations and provided two estimates: one all-inclusive for the piping repairs, tarping, and painting, and one for the piping repairs only, with tarping and painting handled separately. The restaurant area will need to be tarped and protected before repairs begin, and the new piping will be painted to match the existing decor once the work is done.

After-Hours AC Not Holding a Charge in Raleigh

After-Hours AC Not Holding a Charge in Raleigh

What the customer reported

The leasing office for a Raleigh apartment in the 27612 area called after hours about a cooling issue, reporting that for some reason the unit was not holding a charge.

What we found and did

Mario confirmed that the unit was low on refrigerant. He performed a leak search and could not find a steady leak at either the air handler or the heat pump, though he observed a small leak at the suction service valve that did not appear big enough to be the primary leak. Because the lineset running through the wall between the air handler and the heat pump is enclosed, a definitive leak location on that portion could not be confirmed, but Mario determined the leak is likely located there and recommended a lineset replacement.

Gym AC Leak Setting Off Fire Alarms in Raleigh

Gym AC Leak Setting Off Fire Alarms in Raleigh

What the customer reported

The unit serving a gym in the 27614 area of Raleigh was leaking again. It was not frozen anywhere, but the leaks were setting the fire alarms off.

What we found and did

Jeorell learned that mastic tape had been added two days earlier over a hole in the duct that was replaced, and since then the unit had only dripped a little bit, not like before. He found the return still soaked, which can be caused from when the coil was thawing, and confirmed the drain line and ss2 were clear. Jeorell added more mastic tape around where it was dripping and on top where the hole had been. The customer also asked for a quote to replace the system.

Ceiling Leak Above a Downstairs Bathroom in Raleigh

Ceiling Leak Above a Downstairs Bathroom in Raleigh

What the customer reported

A Raleigh homeowner in the 27609 area reported a leak in their ceiling. An inspector had told them it might be the metal ducts sweating, but they were unsure and wanted the source found.

What we found and did

Travis located metal ductwork that is uninsulated and penetrating through the wall into the downstairs bathroom, and determined that condensation forming on the metal ductwork was causing the moisture and leaking. Because the air inside the duct stays significantly colder than the surrounding warmer air, condensation develops on the exterior of the metal, accumulates, and drips down into the downstairs bathroom area. Alex looked over the house to ensure no other plumbing fixtures or pipes were leaking and checked certain aging fixtures to verify they were not leaking and still working properly. Travis discussed the findings with the homeowners and arranged for the install manager to review them and plan the best course of action, charging only for the diagnostic that day.

Result

Alex confirmed the leak was not a plumbing concern, with the aging fixtures he checked found not leaking and still working properly.

Winter Freeze Left HVAC Drain Line Leaking in Raleigh

What the customer reported

A Raleigh homeowner in the 27609 area found a leak in the drain pipe of the HVAC, inside a storage closet on the back side of the home.

What we found and did

Mario inspected the storage closet and confirmed the drain line was leaking because a section of PVC piping had become disconnected. With the homeowner's approval, he replaced the damaged section of PVC, and during the replacement he noted that the damage was caused by the drain line freezing over the winter. He discussed adding heating tape/cable to prevent the issue from happening again, which the homeowner approved; that work will be scheduled separately because an electrician must first install a GFCI outlet to power the heat tape. Mario also discussed the benefits of installing an attic tent and included an estimate for it.

HVAC System Still Leaking Water in Raleigh

What the customer reported

A Raleigh homeowner in the 27613 area called back because the system was still leaking water.

What we found and did

Dexter traced the leaking water to the condensation pan, which had a small crack in it. He was not able to get the part or a price that night, so the replacement was set up as a follow-up, with pricing to be updated later. Dexter noted that the job will need two people to complete.

How Do Techs Pinpoint an AC Leak in Raleigh?

What we found and did

During a scheduled full line set and indoor coil leak search at a home in the 27603 area, Bernard and Manny found that both the line set and indoor coil maintained test pressure with no significant pressure loss or fluctuations indicating a leak in either component. To get that answer, they isolated the line set from the indoor air handler by cutting and brazing the line set ends together, then isolated the indoor coil and pressurized both components independently with nitrogen. After the test, they re-brazed the line set connections to restore the system to its original configuration and left it under nitrogen pressure with the outdoor king valves closed to maintain isolation. A return visit was planned to replace the outdoor TXV once it is received, along with the filter drier to ensure proper system filtration and moisture control.

Result

The nitrogen pressure test ruled out leaks in both the line set and the indoor coil, and the system was left isolated under nitrogen until the outdoor TXV replacement.

How Was My AC's Refrigerant Leak Found in Raleigh?

How Was My AC's Refrigerant Leak Found in Raleigh?

What we found and did

Bernard and Travis completed a comprehensive leak search of the entire system and located an active refrigerant leak at the outdoor TXV. They continued the leak investigation on the line set and indoor air handler, where the electronic leak detector found no refrigerant leaks at the air handler, though a leak within the line set, particularly where the piping travels through the wall chase, remained possible. The king valves were closed to isolate the condenser for continued diagnostics, and the condenser was left off to prevent additional compressor or system damage, while the indoor blower could still be run for air circulation. The homeowner approved replacement of the TXV (estimated at 3-4 days for delivery) and an additional leak search on the line set, with a return visit to be scheduled to complete the repair.

Water Leak Detected on a Rainy Day in Raleigh

What the customer reported

A homeowner in Raleigh noticed water pooling in their basement after a heavy rainstorm.

What we found and did

Travis identified that the water was seeping through a crack in the foundation wall. Travis recommended sealing the crack with a specialized waterproof sealant. He thoroughly cleaned the area and applied the sealant to prevent further water ingress.

Result

The homeowner's basement remained dry after subsequent rainfalls, resolving the issue.

Pro tip

A small crack in your foundation can lead to significant water damage. After heavy rains, inspect your basement for any signs of water ingress and address them promptly.

Why quality leak detection & repair matters in Raleigh

Extreme Summer Heat

Raleigh's hot, humid summers with temperatures often reaching 95°F+ put tremendous stress on HVAC systems. Systems must be properly maintained and sized to handle the extended cooling season from May through September.

Diverse Buildings

The city's diverse neighborhoods from downtown high-rises to suburban homes to historic properties each have unique HVAC needs. Our technicians are experienced with all building types and their specific challenges.

Building Permits

Wake County building codes and city permits have specific requirements for HVAC installations and replacements. We handle all permitting to ensure your system meets local compliance standards.

Urban Heat Island

Urban heat island effects in downtown Raleigh can increase cooling demands by 5-10 degrees compared to surrounding areas. This requires careful system sizing and efficient equipment selection.

FAQ

Leak Detection & Repair in Raleigh: questions answered

Answered by our licensed technicians serving Raleigh.

How do I know if I have a hidden leak?

Common signs include an unexplained increase in your water bill, the sound of running water when all fixtures are off, warm spots on the floor (slab leak), musty odors, or discoloration on walls and ceilings. If you suspect a leak, we can confirm it quickly with a pressure test.

How much damage can a small leak cause?

Even a pinhole leak lets out water every day it runs. Over weeks or months, that leads to mold growth, structural wood rot, damaged insulation, and ruined drywall. Finding it early costs far less than waiting until the damage is visible.

Do you repair slab leaks, or do I need a separate contractor?

We handle the complete process: detection, repair, and pressure verification. For slab leaks, we offer direct repair through the concrete, tunnel-under access, and full reroute options. We discuss the pros and cons of each approach for your specific situation.

Will my homeowner's insurance cover leak damage?

Most policies cover sudden and accidental water damage but not gradual leaks or maintenance issues. We provide detailed documentation including photos, pressure readings, and repair descriptions that help support your insurance claim. We recommend filing promptly after discovery.
