What Is An Air Handler?

Your air conditioner has many parts. The air handler is typically the gray metal box that sits outside your home. This component is one of the most important parts of your AC system because it is home to all the major cooling parts, blower motors, fan belts, and other vital parts of the system. If there is a problem with the AC, chances are, it has something to do with the air handler.

If the air handler fails or the outside case becomes damaged, it’s important to get it fixed or replaced right away. A cracked or dented air handler requires immediate new air handler installation because the physical damage could lead to contamination and a snowball effect of problems with the system.

Thousands of Happy Customers

Was very happy with the quick response to my call for help. It was a very good experience even though it was a stressful situation. They worked with me and were empathetic to my problem and my limitations. They were very thorough in explaining the situation and what needed to be done, explaining and showing me the problem. Once it was decided what I had to do they were quick to get to work and completed the job in a very timely manner. All in all it was a stressful but good experience

– Susan C.

All Pro was awesome we called and they came the same day when our shower drain was leaking into our downstairs ceiling…..the service person was so nice and was very fast and very professional. The price was very reasonable and affordable. They did an outstanding job and we would recommend this company for all your servicing needs. This is the second time using this company, the first was for our water heater and they replaced it fast and very affordable the same day. They came at around 5 and was here until around 9 fixing not only our leaking shower drain but our water pressure value needed to be replaced. They did both and I do not think we would have gotten a better deal or a nicer person to come and do the repairs. All Pro is definitely the people we will be calling for all our plumbing, heating and air conditioning needs from now on.

– Pamela M.

They came to our rescue on January 8, 2018. we had a clogged toilet that overflowed all the way to the downstairs bathroom it was a horrific scene that day. That is when we decided to call All Pro Plumbing. Talked to a nice lady on the phone gave her our info and told us would call back to ensure us someone would come out to help. Within minutes gave us a response time and told us someone will be there within the hour. Sure enough that is when they showed up and quickly diagnosed the problem, went to work, and unclogged whatever was in there that needed to be unclogged. They were efficient, respectful, and professional. They also checkout out other things to make sure that toilet was working fine before they left. Great customer service!

– Vincent M.

Gary was absolutely amazing today. He was friendly, knowledgeable! It seemed a little pricey but our problem needed to be addressed immediately. Great customer service. I would definitely recommend!

– Danielle O.

I would recommend ALL PRO Plumbing to anyone that is looking for good professional service. They installed a sink and garbage disposal for me and did a great job. Their response time is quick. Always either the same day, or the next day

Signs You Need Evaporator Coil Repair Or Replacement

The evaporator coil is the component that works to cool and condense returning air from the system. If the coil becomes dirty, it will freeze and stop working.

Other signs that your evaporator coil needs service include:

  • Uneven temperatures in your home
  • Excess humidity levels
  • The AC turns on and off repeatedly without changing the temperature
  • Warm air coming out of the vents
  • Strange noises coming from the condenser unit as it overworks to make up for a broken coil
  • Clanging sounds coming from the air handler
