Why Isn’t My Air Conditioner Working?

Is your home not cooling as efficiently as it used to? Have you noticed any wet spots near your unit that may indicate a leak? Is your unit making unusual noises or producing strange smells? If so, it’s time to contact an Ontario AC repair technician.

When you call All Pro Plumbing, Heating, Air & Electrical, we will troubleshoot your AC issue by:

  • Checking the air filters to see if they are dirty or clogged
  • Inspecting and cleaning the evaporator coil
  • Checking for refrigerant leaks
  • Looking for issues in the air handler
  • Testing for electronic problems

While maintaining your air conditioner is an important part of keeping your system in optimal condition, we understand that sometimes repairs are unavoidable, especially when you have an older AC unit. Remember that one of the simplest things you can do to keep your system running strong is to regularly change your air filter.

When air filters become dirty, they can restrict the flow of air through the unit, which can cause problems with your unit and negatively impact the quality of your indoor air. The average household should change their filter about every 90 days, but households with pets or allergy or asthma sufferers should change their filter more frequently.

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
