6 Signs You Need AC Replacement

1. Your AC is old – On average, if your AC is over 10 years old it is time to start considering replacement. Older units are more vulnerable to breakdowns, lack of efficiency, and reliability. Don’t wait till the hottest parts of the year to break down when you mostly need it.

2. Poor performance – If your AC isn’t cooling like it used to or perhaps not regulating humidity properly, then it could be time for a new AC replacement.

3. Loud noises – Not all loud sounds coming from your unit are an indication that you need new AC installation. If something is rattling or loose we can fix that no problem but if you hear rumbling or grinding then you could have bigger problems.

4. It requires R22 Freon – While it’s not illegal to use the banned coolant, it will become cost prohibitive as the production has ceased. Consult our Ontario AC replacement experts because that’s going to save you more money in the long run than relying on this banned coolant.

5. Repair after repair – After enough repair calls, another one becomes expensive and inconsequential. Also, be wary of expensive repairs on older units as a new AC installation is on the horizon anyhow.

6. Electrical bills on the rise – As HVAC units age they’ll become less efficient over time. What this means is your indoor air temperature will be fine but it will cost more money to do that each month. Consult our Ontario AC replacement experts if you want to get an energy efficient unit.

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.

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
