Georgetown Hard Water Note: Georgetown draws from the Edwards Aquifer, one of the hardest water sources in Texas. This means AC drain lines accumulate mineral scale significantly faster than in Austin or Round Rock. Annual drain cleaning is strongly recommended here.
Condensate Drain Services
Clear blocked AC drain lines with pressurized flush and vacuum, the most common summer service call in Georgetown.
Repair cracked, disconnected, or improperly pitched drain lines causing leaks or improper drainage.
Clear and flush condensate P-traps that accumulate sludge and cause drain restriction or float switch trips.
Chemical treatment of drain lines to dissolve biofilm and mineral scale buildup, recommended for Georgetown's hard water.
Drain Pans, Pumps & Safety Devices
Install properly configured P-traps to maintain the water seal required for correct drain system function.
Install float switches that shut down the system if the drain pan fills, prevents water damage from drain backups.
Install secondary drain pans under attic air handlers, required by code and essential for protecting Georgetown ceilings.
Replace cracked or rusted drain pans before they leak into ceilings or cause structural damage.
Install or repair condensate pumps for systems that can't gravity-drain, basements, closets, and attic systems without nearby drain access.
Install condensate neutralizers for high-efficiency furnaces and heat pumps that produce acidic condensate.
Emergency response for active water leaks from HVAC drain pans, stop water damage before it spreads.
Moisture Control & Water Leak Services
Comprehensive HVAC moisture management, condensate drainage, humidity control, and insulation assessment.
Full condensate drainage system evaluation and repair, drain lines, trap, pan, float switch, and pump.
Balance system moisture removal for consistent indoor humidity levels in Georgetown's humid climate.
Identify and address condensation problems on HVAC components, ductwork, and supply registers.
Preventive treatments and insulation improvements to eliminate recurring condensation issues.
Diagnose and repair all causes of water leaks from indoor air handler units, drain, coil, or housing.
Address water pooling around outdoor units, improper drainage, defrost water, or refrigerant issues.
The Safety Mechanism Explained
A float switch is a small mechanical safety device that does one job extremely well, it shuts the system down before a clogged or overflowing drain pan can send water into your ceiling or walls. There are two common types used in residential installs. A pan-mounted float sits directly in the primary drain pan, usually a small disc that rises with the water level and trips a switch once it reaches a set height. An in-line safety switch, sometimes called a Wet Switch, mounts directly onto the drain line itself and detects when water backs up inside the pipe due to a downstream clog, tripping before the pan even has a chance to fill.
Both types interrupt the low-voltage control circuit that runs the compressor and blower, essentially telling the thermostat's call for cooling to go unanswered until the water recedes and the switch resets, or until a technician clears the underlying problem. This is a deliberately blunt failure mode, an inconvenient loss of air conditioning is a far better outcome than water damage to drywall, flooring, or insulation, and it is the primary line of defense against exactly the kind of clog that would otherwise cause a slow ceiling leak nobody notices until stains appear.
Code requirements for attic and above-ceiling installations in most jurisdictions, including Georgetown's adopted building code, call for either a secondary drain pan with its own drain line, a float switch, or both, specifically because an attic air handler has no visible pan to check casually the way a closet unit does. We typically recommend both where feasible, a float switch on the primary pan or line catches the everyday clog before it becomes a problem, and a secondary pan with its own float switch, tripping the system if water somehow reaches that second layer, is the true last line of defense.
Installation involves selecting the switch type appropriate to the pan and drain configuration, wiring it into the low-voltage control circuit typically at the air handler's control board or through the existing thermostat wire run, and testing the trip point to confirm the system actually shuts down when triggered rather than just installing it and assuming it works. We test every float switch installation by manually raising the float or introducing water to the sensing point, since an untested safety device is not meaningfully different from having none installed. This is one of the more affordable services we offer given how much water damage it prevents when it works as designed.
