AC Repair: When to Contact a Professional

Your air conditioner plays a crucial role in keeping your home comfortable, especially during the sweltering summer months. While regular maintenance can prevent many issues, there are times when your AC might start acting up. Knowing when to handle the problem yourself and when to call in a professional is key to preventing further damage and ensuring your system runs efficiently. Here’s a guide on when to contact a professional for AC repair.


1. No Cool Air

  • If your AC is running but not blowing cold air, it could be due to several issues, such as low refrigerant levels, a malfunctioning compressor, or a blocked condenser. These are not problems you should tackle on your own. A professional can accurately diagnose and fix the issue.

2. Weak Airflow

  • Weak airflow from your vents could indicate a problem with the ductwork, a clogged air filter, or a failing blower motor. If replacing the filter doesn’t solve the issue, it’s time to bring in a professional to check for blockages or mechanical failures within the system.

3. Frequent Cycling

  • If your AC is constantly turning on and off, known as short cycling, it can lead to higher energy bills and increased wear and tear on the system. Short cycling can be caused by an oversized unit, thermostat issues, or problems with the compressor. A professional HVAC technician can identify the root cause and provide the necessary repairs.

4. Unusual Noises

  • Unusual sounds like grinding, banging, or squealing from your AC unit are never a good sign. These noises could indicate anything from a loose component to a failing compressor. It’s essential to contact a professional immediately to prevent further damage to the system.

5. Foul Odors

  • If you notice strange smells coming from your AC, it could be due to mold growth in the ducts or a burnt-out wire. Both issues require immediate attention from a professional to prevent potential health risks and further system damage.

6. Moisture or Leaks Around the Unit

  • If you see moisture or notice leaks around your indoor or outdoor unit, it could be due to a refrigerant leak or a blocked condensate drain. Refrigerant leaks are hazardous and should be handled by a licensed technician. Similarly, a blocked drain can lead to water damage and mold growth, which a professional can address.

7. High Humidity Levels

  • Your AC should regulate humidity as well as cool your home. If you’re noticing higher humidity levels indoors, it might indicate that your system is struggling and needs professional attention.

8. Rising Energy Bills

  • A sudden spike in your energy bills without a corresponding increase in usage might mean that your AC is working harder than it should be. This could be due to a variety of issues, including dirty coils, low refrigerant, or a failing component. A professional can conduct a thorough inspection to determine the cause.

9. Age of the Unit

  • If your air conditioner is over 10-15 years old and frequently needs repairs, it might be more cost-effective to replace the unit. A professional can help you determine whether a repair or replacement is the better option for your situation.

10. Electrical Issues

  • If your AC unit is tripping the circuit breaker or you’re noticing flickering lights when it kicks on, these are signs of a significant electrical problem. Electrical issues are dangerous and should only be handled by a professional.

by Jiri in Toronto on Twintech Heating and Cooling

From the initial contact we had an excellent experience with this company and all its personnel. Dave Gergley was an excellent, helpful, sales person and solicitous of our needs. He recommended only what was required and did not up sell or make any suggestions for products that we did not need, such as a new A.C. He explained the rebate process and basically outlined how to get the best furnace at the lowest price. When it was time for installation, the technicians could not have been more considerate, careful, attentive to detail, obviously committed to safety and optimum functioning of the appliance they were setting up. We have been perfectly satisfied with the functioning of the furnace and all aspects of acquiring it from the initial contact with Dave through to the installation process and follow ups inquiring about our satisfaction. Also they initiated the rebate process and contacted the appropriate inspection agency to carry it out. We highly recommend this company for all heating and cooling needs and we will contact them again when it is time to replace our A.C.

by Drew in Pickering on Twintech Heating and Cooling

Twintech was excellent from the initial quote and throughout the install. They had a competitive rate for hot water tank and ended up buying the tank from them, had them remove the old tank and install the new one. The day of install they were prompt and out in about 2 hours. Professional , courteous really great guys. We took a look at my 30 year old furnace and they were able to offer some suggestions for future there too.

by Harry in Toronto on Twintech Heating and Cooling

Ever since I turned on my furnace on Oct 2018 I hear a humming sound when the furnace fan kicks in. I called Adamson Air System who installed my furnace 7 years ago and couldn't figure it out the problem. I just wasted money to the guy who couldn't figure it out. I found Twin Tech via Amana / Goodman website. I checked the reviews from previous Twin Tech customers. I called Greg and was onsite on time this morning Sunday, Nov 25 2018. He figured it out what's wrong with the furnace and explained what the previous installer (adamson air system) did wrong when they installed it. His knowledgeable about his job. He recommend to replace the fun motor because the sound is not normal when it's running. Looking forward to see him again to replace the fan motor.

by Roger in Pickering on Twintech Heating and Cooling

Our house is over 22 years old and I had been researching furnaces and A/C brands for a while and thought it was time to take the plunge. After calling three different companies to come in and quote the job, this one won me over. From the first visit from Dave all the way to the end of the install by Greg, Grant, and Piotr, I was glad to have picked this company. Dave was very knowledgeable and really took the time to explain what kind of quality installation I was going to get as well as showing me some of their previous work and certificates.

I was also surprised at how quick the installation took and how nice everything looked afterward, I mean it's only a furnace right? They even re positioned the furnace so that I have easier access to my filter and humidistat, awesome! If you are looking for a company that cares about their customers and is proud about the quality of work they do, along with a great and competitive price, then stop right here because you found it.

by Louis in Pickering on Twintech Heating and Cooling

Once our AC Unit started to fail, I called our past Heating & Cooling provider for support. The response was we needed a new motor for our Furnace. It was time to check their Quote against the marketplace, I reached to other providers online. One of the owner of Twintech (Greg), called me and offered a preliminary Quote and recommendation online. The others needed to set an appointment and came to measure and spend 1 hour before offering a quote. Then I asked Twintech to come finalize their quote to make sure their recommendation was aligned and met our needs.

Twintech was professional throughout the process, easy to deal with (Web, Phone and in Person), price right and met their commitment. Their team expedited the process and installation, arranged for a energy assessment for available rebates and most importantly, delivered on their commitment and managed to do a few extras. They installed a New Furnace, AC unit and Nest thermostat in a day, remove all older units, left the house and outdoors clean and without any debris. Great to be able to support a Local Company, Neighbour and Professional team - Well Done Team Twintech !!!

by Elizabeth and John L from Scarborough on Twintech Heating and Cooling

In October 2018, I contacted Greg at Twintech to do a furnace cleaning. Greg discovered that my furnace, installed in 2006 by another company, had been installed incorrectly, leading to restricted air flow. The heat exchanger was also defective. As well, my furnace was too large for the size of my house.

In my opinion, the biggest concern most of us have as consumers is that we have no idea of the quality or knowledge and experience of the technicians any heating and cooling company will send into our homes. I could have avoided having my 2006 furnace installed improperly (leading to early replacement), had I known about Twintech then.

With Twintech you get it all. Because Twintech is a smaller company you can rest assured that the only technicians who will work in your home are Greg and his twin brother Grant who are co-owners and fully licensed and certified with over 30 years of experience in installing and servicing heating and cooling equipment. They are both friendly and personable and answer all your questions. Their workmanship is outstanding. We had a 2 stage, variable speed Goodman furnace installed. My wife and I noticed a difference in the heating and even temperature of our 2 storey home almost immediately. Our old furnace always heated too much on the main floor and too little upstairs. We are also impressed with how quiet the furnace is.

Twintech's office manager, David Gergley, is equally friendly and not only gave us a competitive quote to replace our furnace (we sought other quotes), but also went above and beyond my expectations when he made arrangements with an energy audit company so that we would be considered for a grant from Enbridge and IESO.

Needless to say, I give Twintech a 10 out of 10 and highly recommend them!

by James, Ajax on Twintech Heating and Cooling

Clean, Fast and Efficient Work. Between all the quotes I received Twintech was a few dollars less and offered the best warranty.

by garysumnec360, Whitby on Twintech Heating and Cooling

They did an excellent job. Everything was very well explained. At the end of the job everything was very well cleaned up.

by Glade, Pickering on Twintech Heating and Cooling

Twintech offered me a competitive price but more importantly great sales and installation service. They did everything with attention to detail and quality workmanship that is hard to find in this day and age. Dave who first game to visit me answered most of my questions and probed about my needs. For the technical/install questions he was unable to answer he quickly had Greg and Grant the owners answer for me. They did not cut corners on the installation or do anything to simply save time. They stayed into the early evening to complete the job and removed all my old components and even fixed up mistakes other workers ahd made in the past. I would highly recommend them and use them again if the need arises in the future. If you are looking for service or new equipment I would highly recommend Twintech be on your list of Heating companies to get a quote from and ask your questions to.

by Anne of Major Oaks in Pickering on Twintech Heating and Cooling

The company epitomizes high quality service: from the initial client interaction with Dave to the installation and follow up with the technical team. One of the key features I look for is the ability of a technical person to talk to and not talk down to the customer when responding to questions and I had quite a few, all of which were very professionally addressed. I was also quite impressed with the follow up service, promptness, the obvious competence of the team who left no stone un-turned to ensure I was a satisfied customer. Thank you guys.

by Aaron on Twintech Heating and Cooling

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

by Linda on Twintech Heating and Cooling

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

We were new homeowners in need of a second opinion. TwinTech Heating & Cooling were Amazing and professional. Very knowledgeable and great service all around. Recommend to anyone looking for honest and reliable services. Treated with respect and care. Thank you Greg, Mitch and Bob!

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
