A loud AC unit can be disruptive and indicate potential issues. Here are some steps to diagnose and possibly resolve the problem:
-
Identify the Type of Noise:
- Buzzing: This could be due to loose parts, debris, or electrical issues.
- Banging: Often caused by loose or broken parts, such as a piston pin, crankshaft, or a loose fan blade.
- Clicking: Could be a sign of a failing thermostat or control board.
- Humming: Usually related to electrical problems or issues with the motor.
- Squealing: Often indicates issues with the blower or fan motor bearings.
-
Check for Loose Parts:
- Inspect the unit for any loose screws, bolts, or parts that may need tightening.
- Ensure the fan blades are not hitting any obstructions.
-
Clean the Unit:
- Turn off the power to the unit.
- Remove any debris or dirt from the exterior and interior components.
- Clean or replace the air filter if it's dirty.
-
Inspect the Fan:
- Ensure the fan blades are not bent or damaged.
- Check for any obstructions that might be hitting the fan.
-
Examine the Compressor:
- If the noise is coming from the compressor, it might be a sign of a more serious issue, like a failing motor or internal component. Professional inspection may be necessary.
-
Check Electrical Components:
- Inspect the wiring and connections for any signs of wear or damage.
- Listen for buzzing sounds which can indicate electrical issues.
-
Lubricate Moving Parts:
- Some parts, like fan motors and bearings, may need lubrication to reduce noise and ensure smooth operation.
-
Balance the Unit:
- Ensure the AC unit is level. An uneven unit can cause increased noise and vibration.
-
Consult the Manual:
- Refer to the AC unit’s manual for specific troubleshooting tips and maintenance instructions.
-
Seek Professional Help:
- If you're unable to determine the cause or fix the issue yourself, it may be best to contact a professional HVAC technician. They can diagnose and repair complex problems that require specialized tools and knowledge.
Regular maintenance and prompt attention to unusual noises can help prevent more serious issues and extend the life of your AC unit.

We couldnt have been more impressed with Twintech - from our first service call with Mitch who took the time to thoroughly diagnose the issue with our furnace, to Dave who proposed a well thought out solution to meet our needs and finally Greg and team who acted quickly to install given we had no heat.
We did our due diligence by soliciting quotes from alternate providers and were shocked and disappointed by the aggressive and manipulative tactics used.
Twintech was honest in their approach, detailed in their product knowledge, reasonably priced, diligent in their follow-up and valued our business.
Well done Twintech! You made this a positive experience for us and our new furnace works beautifully!

We recently purchased an Amana high efficiency furnace and humdifier through Twintech. The work was completed very professionally and the quality of the workmanship was high. There was some additional sheet metal work required to complete the installation, which they were able to complete themselves. Overall I am very pleased with the work and would highly recommend Twintech for a furnace replacement.

We were very pleased with every aspect of the work that was done. They were very professional and polite. They arrived when they said they would and job was completed on estimated time
We would highly recommend them to whoever needed a recommendation
We have a very large dog and they were very understanding and respectful of him being around

The blower on our furnace stopped working leaving us with a cold house. Dave from TwinTech responded immediately to our HomeStars service request. From beginning to end Dave was nothing but helpful, friendly and professional, he did a great job of walking us through the quote and scope of work.
The replacement of the furnace went smoothly. The Guys did a great job, everyone was very friendly and polite. There were no hiccups, or unexpected costs. The only surprise was they left the work area cleaner than it was before they started.
Was a great experience with the whole TwinTech team. Its been a couple of months since the new furnace has been installed and its working great!

I heard about TwinTech when researching new furnaces at furnaceprices.ca. After contacting them about my broken down furnace, Dave came to my house the next day to assess my situation and requirements for a new furnace. He recommended one that had stainless steel heat exchangers which sold me since my previous furnace had issues with a rusted secondary heat exchanger that had to be replaced. Dave also set me up with an appointment with an energy audit company so that I could take advantage of a rebate to help improve the energy efficiency of my home and get some money back. A few days later, Greg, Grant, and Mitch came to install the new furnace and remove the old one. When delivering and removing the furnaces, they were very careful not to damage my floors and walls, and even laid out red carpeting to protect the floors. They were very friendly and professional. The installation was completed in the time they said it would take and they cleaned up their work areas. Within a week, Dave called to follow-up to see how everything was going. I have already recommended them to several friends and family members who may need new furnaces soon.

Twintech did a great job, from Dave the Sales Rep to the Office staff and The Professional Technicians who did the installation. They were professional, courteous, knowledgable and informative. From beginning to follow up we were completely satisfied with everything. Thanks Again. Sincerely The Laytons

Great product, great service, great follow-up. The Twintech Heating and Cooling arranged removal of my existing oil tank and they installed the new gas furnace Amana (made in USA). I am very happy with the final result and support I received throughout the process. My thanks go to the entire Twintech team for their professionalism, great communication and follow-up.

We've had Twintech provide us with work in the past, for an inground pool heater and required rough-in for a new gas stove. More recently they provided the same friendly, professional, timely and clean installation of our new furnace.

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.

The sales process was friendly, informative, and very consultative. They worked hard to earn our business by taking a careful look around our home to assess our needs, providing a lot of information about the product, and answering all our questions and finding the right solution for our home at a competitive price. They prepared us very well for what to expect on installation day, and the installation went very smoothly - no surprises, all very professional! They gave us a call after installation to ensure we were happy with the work. We're very happy that we chose to work with TwinTech to get our new furnace.
