During Arizona summers, an air conditioning system could produce gallons of water daily. This water should go through a drain line and away from your home. But when something clogs that line, when the pan corrodes, or when the switch stops working, the water ends up somewhere else – in your attic insulation, in the ceiling drywall, in the hallway closet where the air conditioning unit is housed, or dripping down the wall. Arizona Water Damage Experts cleans and dries AC leak water damage throughout Arizona.
We service AC leaks at homes and businesses in Chandler (85224), Gilbert (85233), Peoria (85345), Goodyear (85338), and Tucson (85718). We remove wet insulation and drywall, dry the attic framework and the rooms beneath, and tell you what your HVAC tech needs to do to prevent another AC leak.

Leaks of AC units are insidious in that they always begin in places that one would never suspect. In Arizona, the air handlers are usually located in attics, or garage closets, or inside utility closets. A small leak in the unit could soak the attic insulation for days before causing visible signs of dampness on the ceiling below, and by then the drywall will probably already sag and the wooden frame of the ceiling will be wet. The water from the closet unit could leak through the wall plate into carpeting and baseboards in adjacent rooms.
The first step in cleaning up after an AC leak is to determine all areas where the water from the unit had spread. Wet blown-in and batt insulation is removed, since the latter keeps water against the drywall and framing and dries very slowly. Stained and sagged ceiling drywall is cut out. Then attic frames, the ceiling space and all adjacent rooms are dried out using dehumidifiers and air movers. After drying, new insulation and drywall are installed.
The attic temperature in Arizona will be 140 degrees or higher during the summer months, and the combination of this heat with condensation forms an excellent environment for the growth of mold behind drywall and roof sheathing. The air handler in Arizona runs all year long, and what is just a small problem somewhere else is an ongoing leak here.




Here is what to expect when you call about water from your air conditioner.
We tell you how to switch the system off at the thermostat and the breaker to stop new condensate, and how to catch any active drips.
Our crew checks the air handler, drain pan and drain line, then uses meters and thermal imaging to follow water through the attic, ceiling and walls.
Soaked insulation and damaged ceiling or wall drywall are removed so the framing and cavities can dry.
Drying equipment is set up, and we note what failed so your HVAC technician can clear the line, replace the pan or install a safety switch.
Stopping the system stops new condensate. If water is near the unit’s wiring, also switch off the air handler’s breaker. In summer, use fans and close blinds while it is off, and keep the break short.
Put a bucket under ceiling drips and move furniture and electronics out of the way. If the ceiling is bulging, do not push on it. Keep people out from under it.
If you can safely see the unit, check whether the drain pan is full. Do not climb into a hot attic in summer. Call (602) 835-1948 and we will take it from there.
AC leaks often show up as small clues before a ceiling stain appears. Watch for these.
Brown or yellow stains on the ceiling near supply vents or directly below where the air handler sits are the most common first sign.
Many homes have a secondary drain that discharges over a window or eave. Water dripping from that pipe means the main line is clogged.
A musty or damp smell when the system kicks on can mean water is pooling in the drain pan, the ductwork or the insulation near the unit.
Wet insulation in a hot Arizona attic is a mold incubator. Ceiling drywall soaked from above can also sag and fall. The sooner wet materials come out and drying starts, the smaller the repair. Call Arizona Water Damage Experts now.
These are the most common reasons we find behind AC water damage in Arizona homes.
Algae, sludge and dust build up in the PVC drain line until water backs up into the pan and overflows. Long run times in Arizona speed this up.
Metal secondary pans under attic units rust through with age, and plastic pans crack. Once the pan fails, overflow goes straight into the ceiling.
A float or safety switch should shut the system off when water rises in the pan. Many older systems never had one, or the switch has failed.
Dirty filters, low refrigerant or blocked airflow can freeze the evaporator coil. When it thaws, more water comes off at once than the drain can handle.
AC leak jobs follow a set process so the attic, ceiling and rooms below are all dried and restored.
We inspect the air handler, pan and drain line, then map moisture in the attic, ceiling and walls with meters and thermal imaging.
Saturated insulation is bagged and removed, and wet or sagging drywall is cut out to expose the framing for drying.
Dehumidifiers and air movers dry the attic framing, ceiling cavity and the rooms below, with daily moisture readings.
New insulation and drywall are installed and finished, and you receive notes on what your HVAC technician should repair or add.
Water damage can take different forms, and thus each requires a unique treatment. Arizona Water Damage Experts provides all types of water damage repair services under one roof so that you will not have to juggle many contractors.

Before
After
1
A clogged condensate line in a Gilbert (85233) attic overflowed for several days in July, leaving a sagging stain above the master bedroom.
We removed wet blown-in insulation and the damaged ceiling drywall, dried the attic framing for three days and rebuilt and textured the ceiling.
The ceiling matched the rest of the room, and the HVAC technician added a float switch to the pan.
2
The air handler in a Peoria (85345) hallway closet leaked under the wall into the carpet of two bedrooms.
We extracted the carpet, removed the pad and lower drywall in the closet, and dried the wall cavities and floors.
The carpet was saved with new pad, and the owner had the drain line cleaned and a new pan installed.
3
A frozen coil in a Tucson (85718) home melted overnight and flooded the attic pan, sending water through a light fixture.
We cut power to the circuit, removed the wet ceiling section and insulation, and dried the attic and room.
The owner switched to a regular filter replacement schedule to prevent coil freezing.
Immediate response, honest opinion, and dry home top the list of concerns of the customers.
We had a leak coming through the ceiling at midnight. They answered within two rings and came to us in less than an hour. They remained cool headed, guided us through and saved our flooring.

AC leaks show up in different ways depending on where the unit sits. Here are three common situations.
Water dripped from a ceiling vent in the living room every afternoon when the AC ran hardest.
We found condensation on an uninsulated duct and a soaked area of ceiling insulation, removed the wet insulation and dried the ceiling.
Ask your HVAC technician to check duct insulation in the attic, especially near supply vents.
A rusted secondary pan under an attic unit let water soak through to the hallway ceiling.
Wet insulation and drywall were removed, the attic and hallway were dried, and the ceiling was replaced.
Have attic drain pans inspected during spring AC service and replace rusted pans.
The condensate line from a garage air handler backed up and ran down the wall into the laundry room.
We dried the shared wall and replaced the lower drywall and baseboards in the laundry room.
Flush the condensate line with a cup of white vinegar every few months during cooling season.
Answers to common questions about AC leak water damage cleanup in Arizona.
An AC could leak due to a clogged condensate line, a faulty drain pan, frozen evaporator coil, and even improper installation of HVAC equipment. With extreme heat experienced in Arizona during the summer, proper care of air conditioning units becomes critical. Arizona Water Damage Experts offers assistance with water damage caused by air conditioning leaks and identifies the damaged areas that would require drying.
In case the leaking unit needs to be shut off and the electrical risk has been identified, try moving the items from the area. Then, contact your air conditioning contractor and have them investigate the cause of leakage. In case of wet drywall, flooring, ceilings, and other materials, the water damage specialists at AZ Water Damage Experts can help you identify it and take necessary actions.
Is there a possibility that moisture could travel under the flooring, behind walls, into the ceilings, and around cabinets from AC leaks? The hidden moisture could lead to degradation of building materials, unpleasant smells, and even mold. Proper moisture detection will assist with identifying the affected areas and further actions on structural drying.
Water damage from AC leaking needs immediate attention in order to prevent additional damage. Standing water as well as wet building components tend to degrade as time passes, especially when they are held in places that are hard to reach. Immediate water removal, moisture testing and drying will help you to save your property in Arizona.
Water damage coverage may differ according to the type of your insurance policy, as well as the nature of the damage and any exclusions. Some cases of water damage are covered by insurance, while others are not. You should contact your insurance provider and check what is covered. It is also important to take photos of the damaged areas before cleanup where possible.
The duration of your restoration process depends on the amount of water leakage, affected building materials and the extent of moisture distribution in hidden places. The smaller water damage requires minor cleaning and drying, while larger water damage involving saturated drywall, flooring or ceiling may take several days to clean up. Arizona Water Damage Experts can analyze your affected areas and choose the proper restoration technique.
Yes, mold does occur in materials where moisture is present, including Arizona which experiences a relatively dry weather. Leaking air conditioners lead to dampness around ceilings, walls, carpets, and insulations. Cleaning up quickly and drying up are effective ways of minimizing chances of mold occurrence, although mold may need additional treatment if present.
