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.

Reasonable price and the workmanship was prompt and timely and the employees were great to deal with.
May 2, 2020
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.

When our old oil furnace finally broke down we decided it was time to finally convert to natural gas and finally install central air conditioning at the same time. Knowing it was going to be a significant investment for us, we wanted to make the right choice. Twintech came highly recommended by a friend and we were not disappointed. From the first contact with the salesperson, until the final touches on the installation, we were so pleased with their service. Everyone from the company was so friendly, efficient and a pleasure to deal with. Best of all, the cost was very competitive. We would certainly recommend Twintech to anyone requiring HVAC work in their home.

Mitch from Twintech came out for our annual furnace inspection. We found him to be friendly, conscientious & he left the work area clean. We were also very impressed with the thoroughness of the job he did. This is the 2nd job weve had Twintech do for us & have been very happy with the results for each. We highly recommend this company. Thank you, Mitch, Dave & Greg.

Work was done on schedule, professionally, according to quote and with minimal inconvenience to building users. Very happy with the end result. The only area for improvement from my experience - need more timely quoting process.

The team was great! Very knowledgeable, professional and extremely helpful. A few days after install the unit didnt seem to be working, user error, but within minutes of contacting them..on a Saturday.. a tech was on the phone troubleshooting with us. I highly recommend Twintech for your cooling or heating needs. They stand by their products and a pleasure to deal with.

During the hottest week in the summer our old A/C decided to call it quits. I called Twintech Heating & Cooling after receiving a referral from a family member; came highly rated for being an honest, family-run business, who appreciates their customers. Dave was able to accommodate my hectic schedule and book a late evening appointment to walk through the specifics. Greg and Mitch arrived exactly on time a few days later, were very polite and friendly, and within a couple of hours had a new unit up and running. I also received a follow-up call to ensure we were happy with the Amana.
