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.

I have used Twintech many times over the years. They always arrive quickly and get the issue fixed. The most recent incident was when my air conditioner broke last week I called Greg at 11:30am and he was at my home by 2:30pm he had the unit fixed by 3:30pm. Twintech are very reliable and honest and they are experts in the field. I have already recommended them to many of my friends. I would not use anyone but them for my heating and air conditioning issues.

I would highly recommend these guys, professional, fast and competitive pricing. I moved into this place with no working AC unit with a 8 month baby, he was able to come with in a week to fix even in the busy summer days. He really values his customers , I am already recommending to my neighbors.

Very impressed they arrive to quote even though I had forgotten to call them back to confirm date & time. They showed the day before installation to deliver the unit. Returned the next day as promised at 9am. Project was completed in a professional manner. They even fixed a few things that they noticed were not installed correctly, or to code by previous heating & air contractors we had at our residence before. Would recommend this company to everyone!

Greg removed old oil furnace and oil tank from basement relocated new Napoleon propane furnace to allow duct work to be rerouted to a much more suitable location. Moved air conditioner to the new furnace. Dave recommended two available grants to assist with cost. They kept to their original quoted price which was substantially lower than a competitors for the same furnace and work. They completed the work as stated when stated and left the area clean and tidy. We are very pleased with the outcome.

We had Grant and Greg Dainty quote to replace our 20 yr old furnace. I have known them for years and have had other jobs done by them ( AC and Pool Htr). The price was very reasonable and the job was completed in one day.

TwinTech was the right choice. Our consultation with Dave set the tone. Professional and knowledgeable, we even received a follow-up call within hours of our install completion, wow! TwinTech arrived as scheduled to install our A/C unit. Within minutes of arrival Greg noted and explained a few out of code faults on our furnace installed by another company, problems fixed, thanks TwinTech. Greg, Grant and "Subaru" Pete were meticulous start to finish. Highly recommended!

Twintech replaced our aging +20 yrs old Furnace & AC with the variable high efficiency Napoleon Furnace matched with the Goodman AC. Sales guy ,Dave was great, gave a no pressure estimate, explained about the Government Rebate program which they took care of completely including arranging the home energy audit. On the scheduled day Greg and his team arrived on time, did a great job and completed the same day , extremely professional and courteous, cleaned up everything , tested the system, Greg took his time to explain the setup. Very impressed with the Napoleon Furnace 9600 which did a great job in maintaining a comfortable temperature last winter and now with the hot weather the Goodman AC cooled the house in much less time than the old AC unit could ever. From start to finish Twintech were great and have no hesitation in recommending them 100%.

The Twintech team did an excellent job installing our new Goodman air conditioner. They were polite and professional. Greg was knowledgeable and clearly experienced. Thank you Twintech for bringing our cooling system up to current regulations. Job well done!

Dave from TwinTech was very knowledgeable, professional and thorough in the buying process. He helped us to identify the best furnace for our home and our budget. When we needed a new filter a year later and seemed to have a problem finding the right one, I called Dave up and he delivered a filter to me the next day! The cost was on par with other retailers, but it was this unexpected personal service that really was impressive. The furnace? Works like a charm.
