There are a number of reasons that can cause your AC unit to freeze up. Air conditioners require unrestricted airflow to keep the area around the cold coil at temperatures above freezing. Warm air recirculated from the home through the return is what keeps the the operating temperature up and prevents the coils from freezing. Without it, condensation builds and AC coils freeze. Dirty air filters and/or closed air registers can impede airflow, it’s a good idea check air filters regularly and make sure the registers have smooth air flow. A freeze-up can also be caused by low refrigerant levels and/or improper fan operation. Low refrigerant levels can actually make the coils run too cold, and a faulty fan prevents air from moving at necessary volumes.

Clogged AC drains and faulty thermostats are also common causes of a freeze ups. In the cooling process, an AC unit collects water condensation in a pan below the unit that drains outside. Sometimes when coils freeze, it causes a blockage of the drain hole in the condensate pan. This can really get messy if your pan overflows and starts flooding into the room or garage. Running an air conditioner with frozen coils can also lead to extensive damage of the AC compressor. This is the most expensive part of an AC unit, and it’s not a repair or replacement expense that anyone is usually prepared for. If your AC isn't running properly and you suspect it may be frozen, it’s probably best to call a certified HVAC technician.

What is a Rooter...?

We hear the term "rooter" or "roto-rooter" often in the plumbing world. A rooter is a machine that was invented out of frustration and necessity in order to clear tree roots from drain pipes. One of the most common drain clogs or stoppages come from tree roots invading underground sewer or drain pipes. A rooter drain cleaning tool is essentially a heavy duty drain-snake with rotating blades on the end. The plumbing professional feeds the rotating blades into the root infested pipe literally cutting the roots away leaving you with a smooth, clean inner pipe wall.

It is amazing how often roots can completely take over a drain pipe. Just recently one of our plumber removed a twelve-foot section of root from a drain pipe in Chandler Arizona. The video was taken with the plumbing technician's cell phone and the resolution isn't the greatest... but it is a great example of how invasive tree roots can be to your plumbing system.



Drain problems of this magnitude require more than the right equipment to resolve. They require training and experience. It is easy to actually do more damage than good with a drain-rooter if you have never used one before. If you suspect that your sewer or drains are blocked, make sure to call an Arizona plumbing professional to help clean out your system and get all of your drains flowing smoothly.
