YOUR AC DRAIN LINE
MAY BE FEEDING
TERMITES
Most Phoenix-area builders route the AC condensate drain to exit just 2–3 inches from your foundation. In Arizona's desert climate, that drain line is one of the only chronic moisture sources near your home's wood framing — and termites know it.
Bradford also covers clogged drain lines and improperly installed overflow pans — the leading cause of ceiling water damage in Surprise and Peoria homes.

THREE AC DRAIN PROBLEMS BRADFORD FIXES IN SURPRISE
Most HVAC companies only think about drains when they're clogged. Bradford looks at the full picture — where the water goes, what it attracts, and what happens when the system fails.
Termite Attraction: The Hidden Risk of Short Drain Lines
Most Overlooked RiskArizona is one of the highest-risk states for subterranean termite damage — and your AC drain line may be actively inviting them to your foundation.
Most Phoenix-area home builders route the AC condensate drain to exit just 2–3 inches from the foundation. This is code-compliant, but it creates a chronic moisture source at the most vulnerable part of your home's structure: the wood sill plates and framing that sit directly on the concrete foundation.
Subterranean termites — the species responsible for 95% of termite damage in Arizona — need moisture to build their mud tubes and establish colonies. In the desert, moisture is the limiting factor. A drain line 2 inches from your foundation eliminates that limitation.
Bradford's Recommendation
Extend your AC condensate drain line at least 2 feet beyond the foundation perimeter. This eliminates the chronic moisture source at your foundation and removes a primary termite attractant. Cost: $150–$300. Bradford can perform this during any AC service visit.
Clogged Drain Lines: Algae, Mold & Water Backup
Most Common ProblemThe condensate drain line is a dark, damp PVC pipe — ideal conditions for algae and mold growth. In Surprise and Peoria, the combination of warm temperatures and monsoon-season humidity accelerates biological growth inside drain lines.
A clogged drain line causes water to back up in the primary drain pan. If the overflow pan and secondary drain are properly installed, the water exits safely. If not — and many Phoenix-area homes have improperly installed overflow systems — water overflows onto your ceiling.
Signs of a clogged drain
- Water dripping from air handler
- Musty smell from vents
- AC shutting off unexpectedly
- Water stains on ceiling below air handler
Bradford's fix
- Flush drain line with pressurized water
- Treat with algaecide tablets
- Inspect and clear secondary drain
- Add float switch if not present
Overflow Pan Failures: The Cause of Ceiling Water Damage
Most Expensive ConsequenceThe overflow pan (secondary drain pan) is the last line of defense against ceiling water damage. It sits directly under the air handler and is designed to catch water if the primary drain clogs.
The problem: many Phoenix-area homes have overflow pans that are improperly installed, cracked, or connected to secondary drains that terminate in wall cavities rather than exterior exits. When the primary drain clogs and the overflow pan fails, water saturates the ceiling drywall — causing stains, mold, and in severe cases, ceiling collapse.
What Bradford checks during every AC service visit:
Adding a float switch ($75–$125 installed) is the single most cost-effective way to prevent ceiling water damage from a clogged drain.
HOW BRADFORD EXTENDS YOUR AC DRAIN LINE
Extending the condensate drain is a straightforward add-on to any AC service visit. Here's what Bradford does:
Locate the existing drain termination
Bradford identifies where your current drain line exits the home — typically through the stucco or block wall.
Assess the extension route
Bradford determines the best path to extend the drain 2+ feet beyond the foundation, avoiding landscaping and hardscape.
Install PVC extension
Bradford adds a PVC extension to the existing drain line, sloped for proper drainage, terminating at least 2 feet from the foundation.
Test and inspect
Bradford pours water into the drain pan to confirm proper flow through the extension and checks for any leaks.
Cost: Drain line extension typically costs $150–$300 as a standalone service, or can be added to any Bradford AC service visit for less. The cost of a single termite treatment in Arizona averages $1,500–$3,000. This is one of the highest-ROI preventive investments a Surprise homeowner can make.
WHY THIS MATTERS MORE IN ARIZONA THAN ANYWHERE ELSE
Arizona Termite Risk
Arizona ranks among the top states for subterranean termite activity. The Sonoran Desert's dry climate means termites are constantly searching for moisture sources. Your AC drain line — running 9–10 months per year and producing gallons of water daily during monsoon season — is one of the most reliable moisture sources near your home's foundation.
Monsoon Season Humidity
Phoenix's monsoon season (June–September) brings relative humidity of 50–70% during storms — dramatically increasing the amount of condensate your AC produces. A 3-ton AC that produces 3–5 gallons per day in dry conditions may produce 15–20 gallons per day during a monsoon. All of that water exits through your drain line, and if it's terminating 2 inches from your foundation, it's saturating the soil at your home's most vulnerable point.

TERMITE PROBLEM? YOUR AC DRAIN MAY BE THE CAUSE.
If you've had a termite inspection or treatment recently, ask your pest control company whether your AC condensate drain is contributing to the moisture problem. In Surprise and Peoria, the two most common termite moisture sources are irrigation leaks and AC drain lines running too close to the foundation.
Bradford Heating & Cooling works alongside trusted pest control partners in the West Valley. We extend your AC drain line 2+ feet beyond the foundation — eliminating the moisture source — while your pest control partner treats the existing colony. Addressing both sides of the problem is the only way to achieve a lasting solution.
