Air Conditioner Repair: When to Consult a Professional
Posted On: June 20, 2024
Repairing an air conditioner (AC) can sometimes be straightforward, but there are situations when consulting a professional is the best course of action. Here are some key indicators that it might be time to call in an expert:
1. Unit Not Turning On
- Potential Causes: Electrical issues, thermostat problems, or a tripped circuit breaker.
- Why Consult a Pro: Diagnosing electrical problems safely requires specialized tools and knowledge. A professional can accurately identify and fix the issue.
2. Inadequate Cooling
- Potential Causes: Low refrigerant levels, dirty coils, or a malfunctioning compressor.
- Why Consult a Pro: Handling refrigerants requires certification, and accurately diagnosing compressor issues involves technical expertise.
3. Unusual Noises
- Potential Causes: Loose components, motor issues, or debris caught in the unit.
- Why Consult a Pro: Identifying the source of unusual noises and determining the best repair method often needs experience with AC systems.
4. Water Leaks
- Potential Causes: Clogged drain lines, a broken condensate pump, or improper installation.
- Why Consult a Pro: Preventing water damage and ensuring proper drainage often requires a thorough inspection and repair, which a professional can provide.
5. Frequent Cycling
- Potential Causes: Thermostat issues, dirty filters, or electrical problems.
- Why Consult a Pro: Determining the underlying cause of frequent cycling and correcting it to prevent wear and tear on the unit requires professional diagnostics.
6. High Energy Bills
- Potential Causes: Inefficient operation due to dirty coils, low refrigerant, or an aging system.
- Why Consult a Pro: A professional can perform an energy audit, identify inefficiencies, and recommend cost-effective solutions or upgrades.
7. Frozen Coils
- Potential Causes: Restricted airflow due to dirty filters, low refrigerant, or malfunctioning fans.
- Why Consult a Pro: Addressing frozen coils involves understanding both the airflow and refrigerant systems, which a professional is trained to handle.
8. Thermostat Issues
- Potential Causes: Incorrect calibration, electrical issues, or sensor problems.
- Why Consult a Pro: Diagnosing and fixing thermostat issues ensures accurate temperature control and efficient operation.
9. Foul Odors
- Potential Causes: Mold growth, burned-out components, or dirty filters.
- Why Consult a Pro: Identifying and eliminating the source of odors often requires a deep clean or replacement of parts, which should be handled by a professional to ensure safety and efficacy.
10. Tripped Circuit Breakers
- Potential Causes: Electrical issues within the unit, overloading, or a short circuit.
- Why Consult a Pro: Repeatedly tripping breakers indicate serious electrical issues that require a certified technician to safely resolve.
Benefits of Consulting a Professional:
- Safety: Avoiding the risk of injury or further damage to the unit.
- Efficiency: Faster and more accurate diagnosis and repair.
- Warranty Protection: Ensuring that repairs comply with warranty requirements.
- Expertise: Leveraging specialized knowledge and tools that homeowners typically do not possess.
In summary, while minor maintenance tasks like changing filters can be done by homeowners, significant issues or anything involving electrical components, refrigerants, or intricate diagnostics should be handled by a professional to ensure safe and effective repairs.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

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 did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
