Most Common AC Repairs

Air conditioning systems can require various repairs over time due to wear and tear, lack of maintenance, or other issues. Some of the most common AC repairs include:


  1. Refrigerant Leaks: Refrigerant leaks can cause your AC system to malfunction and not cool effectively. Repairing leaks and recharging the refrigerant is a common maintenance task.


  2. Dirty or Clogged Filters: Dirty or clogged filters restrict airflow, reducing efficiency and possibly causing the system to freeze up. Regularly cleaning or replacing filters is essential for proper AC operation.


  3. Thermostat Issues: Problems with the thermostat can result in inaccurate temperature readings or difficulties in maintaining the desired temperature. This can often be resolved by recalibrating or replacing the thermostat.


  4. Condenser or Evaporator Coil Issues: Dirt, debris, or corrosion on the condenser or evaporator coils can hinder heat exchange, reducing cooling efficiency. Cleaning or repairing these coils may be necessary to restore optimal performance.


  5. Fan Problems: Issues with the outdoor fan or indoor blower fan can cause airflow problems, leading to reduced cooling capacity or system failure. Repairs may involve fixing motor issues, replacing belts, or repairing fan blades.


  6. Electrical Problems: Faulty wiring, capacitor issues, or electrical component failures can prevent the AC system from functioning correctly. Electrical repairs should be handled by qualified technicians to ensure safety.


  7. Frozen Coils: Insufficient airflow or refrigerant issues can cause the evaporator coils to freeze, resulting in reduced cooling capacity. Identifying the underlying cause and thawing the coils may be necessary to prevent further damage.


  8. Compressor Malfunctions: The compressor is a crucial component responsible for circulating refrigerant and facilitating heat exchange. Compressor failures can result from various factors and often require professional diagnosis and repair.


  9. Drainage Problems: Clogged condensate drains can lead to water accumulation, which can damage the system and promote mold growth. Clearing blockages and ensuring proper drainage is essential for preventing water-related issues.


  10. Ductwork Issues: Leaks, blockages, or poor insulation in the ductwork can compromise airflow and reduce system efficiency. Repairing or sealing ductwork can improve overall performance and energy efficiency.


Regular maintenance and prompt repairs can help prolong the lifespan of your air conditioning system and ensure efficient operation, reducing the likelihood of costly breakdowns and repairs. It's recommended to schedule routine inspections and maintenance with a qualified HVAC technician to address any potential issues before they escalate.

by John from Toronto on Twintech Heating and Cooling

Our furnace bit the dust, and Twintech came out to troubleshoot and diagnose the problem within a couple of hours. Mitch was super helpful, patient, and answered all of our questions. When we decided to get the furnace replaced, the crew was over first thing the next morning and did a fantastic job. Not only did they complete the job in a few hours, but they cleaned up and respected our house as they went, and answered all of our follow-up questions. I've used Twintech for our HVAC needs in the past and will continue to do so. I'd recommend them to anyone, and it feels good to support a local, family-owned business.

by Ryan k on Twintech Heating and Cooling

Dave and the Twintech team were fabulous from day 1 and helped us through the process to identifying a new furnace and AC unit. This was our first time through this process and Dave did a thorough job explaining all the components and was very patience answering all our questions. Dave provided great insights and fair pricing.

The Twintech team did an awesome installation. Very clean and efficient. I would highly recommended their service.

by Louise in Scarborough on Twintech Heating and Cooling

We had a new Amana furnace installed by Twintech and we were very pleased with the installation. It is nice to have a warm house again.

by Private User on Twintech Heating and Cooling

Excellent job. Excellent service. Competitive price. Its rare to find a company with the knowledge and professional results we have experienced with Twintech. The clean and neat installation with attention to detail and drop sheers to respect our property is a clear indication of Twintechs high level of integrity. The 1-1/2 gas line upgrade they did for our pool 3 years ago was awesome. Can't say enough. Thank-you Twintech.

by Private User on Twintech Heating and Cooling

Twitch did a great job with the installation of our new furnace. I really appreciated their honesty and I could trust what they were telling me. Another company tried to suggest significantly more work at a greater cost claiming it was necessary to meet current building code. Twintech is very fair. All staff I meet were friendly, polite and trustworthy. I would recommend Twitch for a furnace.

by Private User on Twintech Heating and Cooling

This is a professional team that's easy to deal with. I would strongly recommend them

by hj.taggart in OSHAWA on Twintech Heating and Cooling

Very professional firm from start to finish!
They removed the old oil tank and furnace. They installed air conditioning and a new propane furnace.
Professional installation, on time and no mess.
Very pleased with their work and would highly recommend the company. Our house is three stories so they spent the time to do all the calculations to make sure we would have great performance on each floor.
Thank you again!

by susieschoeppler in Oshawa on Twintech Heating and Cooling

Upon a routine yearly maintenance, it was discovered there was a leak in the heat exchanger and a I needed a new furnace. I know nothing about these things and was completely stressed out. The company I had the maintenance plan with quoted me a huge number to rent a furnace, I just wanted to cry. Then I spoke to Dave at Twintech. He was so knowledgeable and calming, provided me a fair quote and within a few days I had an amazing crew show up to my house and install my new energy efficient furnace! I have already recommended these wonderful people at Twintech to a good friend of mine. Thank you Twintech!!

by Private User on Twintech Heating and Cooling

Great service and great people to deal with, from sales to installer. I highly recommend this company.

by GR from Oshawa on Twintech Heating and Cooling

Twintech replaced our aging furnace and air conditioner recently. I highly recommend this company. Their quote was competitive, they were on time and respectful of our home and extremely professional. From the salesman to the installers and the owner who followed up afterward to ensure we were satisfied, we are very pleased with the service. We are looking forward to working with this company for all of our HVAC needs for the years to come. Excellent workmanship and service!

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 definitely recommend TwinTech!
