Prevent Water Damage
Water is dripping from your ceiling and it is getting worse
Every air conditioner, mini-split, and fan coil produces condensation. When the drain line clogs — and in NYC's humid summers, they all do eventually — that water has to go somewhere. Usually it is your ceiling, wall, or floor.
Water dripping from the ceiling
A clogged condensate line overflows the drain pan and water seeps through the ceiling below. What starts as a drip can become a major water damage event within hours
AC shuts off by itself
Many modern systems have a safety float switch that shuts down the AC when the drain pan fills up. Your system keeps turning off not because of a mechanical problem — the drain is clogged
Musty smell from vents
Standing water in a clogged drain pan breeds mold and bacteria. That musty smell coming from your AC is biogrowth in the drain system — and you are breathing it
Water damage to floors and walls
Unnoticed condensate leaks destroy drywall, warp hardwood floors, and create mold inside walls. A $150 drain clearing prevents a $5,000+ water damage repair
Water was dripping onto our reception desk for 3 days. Two plumbers said it was a pipe leak in the ceiling. Art HVAC checked the AC above and found a completely clogged condensate line. Cleared it in 20 minutes. Problem solved.
WHAT WE DO
Complete Condensate Solutions for Every System
From a quick drain clearing to a full condensate piping redesign — we handle every condensate drain issue for residential and commercial HVAC and refrigeration systems.
Drain Line Clearing
Stop the Leak Now
We clear clogged condensate lines using compressed nitrogen, wet-dry vacuum, and enzymatic treatments. Most clogs are cleared in under an hour. We also clean the drain pan, check the trap, and treat the line to prevent future buildup.
Condensate Line Installation
New AC, Mini-Split & Fan Coil Drains
New AC installation, mini-split mounting, or fan coil replacement — every unit needs a properly pitched condensate drain with a trap, clean-out access, and code-compliant termination. We design and install drain lines that flow reliably for years.
Preventative Drain Maintenance
Stop Clogs Before They Start
Add condensate drain clearing to your HVAC maintenance plan. We flush and treat every drain line during seasonal service — eliminating the algae and slime buildup that causes 90% of condensate clogs.

HOW IT WORKS
From Drip to Dry in Four Steps
Most condensate drain clogs are cleared same-day, often within an hour of arrival.
Call Us
Describe the leak — location, which AC unit, how long it has been dripping. We dispatch same-day for active leaks.
Locate & Clear
We trace the condensate line, locate the clog, and clear it using nitrogen flush, vacuum, or mechanical means. Drain pan is cleaned and sanitized.
Treat & Prevent
We apply bio-treatment tablets and verify the float switch is working — preventing future clogs and protecting against overflow.
Verify & Clean Up
We run the AC, verify water flows freely through the drain, and clean up any mess from the leak. Most jobs are completed in under an hour.
FAQ
Questions We Hear Every Day
Practical answers about condensate drain issues.
The most common cause is a clogged condensate drain line. Your AC removes humidity from the air and that moisture collects in a drain pan, then flows out through a drain line. When that line clogs with algae, mold, or debris, water backs up and overflows — dripping through ceilings and walls. It is usually a quick, inexpensive fix.
At minimum, twice a year — before cooling season (spring) and mid-season (August). In NYC's humid summers, condensate lines are the #1 cause of AC-related water damage. Adding drain maintenance to your regular HVAC service prevents 90% of overflow incidents.
Yes — many modern AC systems have a safety float switch in the drain pan. When the condensate cannot drain and the pan fills up, the float switch shuts off the AC to prevent water damage. If your system keeps shutting off on humid days, a clogged drain is the most likely cause.
A condensate pump is needed when the drain cannot flow by gravity — for example, when the AC unit is in a basement below the sewer line, or a mini-split is mounted on a wall with no nearby drain. The pump collects condensation and pumps it up to a drain or out to exterior. We install and service all types of condensate pumps.
A standard drain line clearing costs $150-250 depending on access and severity. Condensate pump installation runs $300-600. Adding drain service to an existing HVAC maintenance plan costs significantly less. Considering that a single condensate overflow can cause $5,000+ in water damage, regular drain service is one of the best investments in building maintenance.
