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.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !
