AC Repair: When to Contact a Professional

Your air conditioner plays a crucial role in keeping your home comfortable, especially during the sweltering summer months. While regular maintenance can prevent many issues, there are times when your AC might start acting up. Knowing when to handle the problem yourself and when to call in a professional is key to preventing further damage and ensuring your system runs efficiently. Here’s a guide on when to contact a professional for AC repair.


1. No Cool Air

  • If your AC is running but not blowing cold air, it could be due to several issues, such as low refrigerant levels, a malfunctioning compressor, or a blocked condenser. These are not problems you should tackle on your own. A professional can accurately diagnose and fix the issue.

2. Weak Airflow

  • Weak airflow from your vents could indicate a problem with the ductwork, a clogged air filter, or a failing blower motor. If replacing the filter doesn’t solve the issue, it’s time to bring in a professional to check for blockages or mechanical failures within the system.

3. Frequent Cycling

  • If your AC is constantly turning on and off, known as short cycling, it can lead to higher energy bills and increased wear and tear on the system. Short cycling can be caused by an oversized unit, thermostat issues, or problems with the compressor. A professional HVAC technician can identify the root cause and provide the necessary repairs.

4. Unusual Noises

  • Unusual sounds like grinding, banging, or squealing from your AC unit are never a good sign. These noises could indicate anything from a loose component to a failing compressor. It’s essential to contact a professional immediately to prevent further damage to the system.

5. Foul Odors

  • If you notice strange smells coming from your AC, it could be due to mold growth in the ducts or a burnt-out wire. Both issues require immediate attention from a professional to prevent potential health risks and further system damage.

6. Moisture or Leaks Around the Unit

  • If you see moisture or notice leaks around your indoor or outdoor unit, it could be due to a refrigerant leak or a blocked condensate drain. Refrigerant leaks are hazardous and should be handled by a licensed technician. Similarly, a blocked drain can lead to water damage and mold growth, which a professional can address.

7. High Humidity Levels

  • Your AC should regulate humidity as well as cool your home. If you’re noticing higher humidity levels indoors, it might indicate that your system is struggling and needs professional attention.

8. Rising Energy Bills

  • A sudden spike in your energy bills without a corresponding increase in usage might mean that your AC is working harder than it should be. This could be due to a variety of issues, including dirty coils, low refrigerant, or a failing component. A professional can conduct a thorough inspection to determine the cause.

9. Age of the Unit

  • If your air conditioner is over 10-15 years old and frequently needs repairs, it might be more cost-effective to replace the unit. A professional can help you determine whether a repair or replacement is the better option for your situation.

10. Electrical Issues

  • If your AC unit is tripping the circuit breaker or you’re noticing flickering lights when it kicks on, these are signs of a significant electrical problem. Electrical issues are dangerous and should only be handled by a professional.

They've cleaned my furnace a couple of times and mentioned that the hot water tank standards were going to change soon so I decided to change mine out.

There were a few challenges during the process but the installers handled the problems without missing a stride! I now have really hot water again!

by Heidi B on Twintech Heating and Cooling

Bob and Greg made us feel comfortable withe process through their thorough explanation and knowledge of the right furnace for our needs.

So happy with our decision and new furnace we will be looking into get our rental water heater replaced and installed by Twintech team. We feel better having their knowledge on our side and will only trust them with any further maintenance of furnace.

by Kirushanth Rasiah on Twintech Heating and Cooling

Customer service and knowledge is priority in this industry, and Twintech has it. I've dealt with their team for maintenance and a furnace replacement. They're accommodating and make great recommendations, and came through at a great price over the big guys in the industry. They'll be my next call when I need service or maintenance.

by Leonard Glass on Twintech Heating and Cooling

I decided that the noises and age of the existing furnace which was old and not very efficient to replace it. Gave Greg a call and Grant and Greg got to work on it. Because of supply issues with the current heating type that would be an easier install Greg convinced me to change the location of the system and it would provide me better service for heat and efficiency. I had skeptical but went ahead anyway putting trust in Greg And Grant. Greg, Grant and Mitch came through and in 2 days had completely relocated my heating and A/C system. I can honestly say Greg was right my old house has been warmer and more evenly heated as it ever was. For anyone reading this rather long winded review can take my word for it, Twin Tech can take care of your needs.

by Nicole Alain on Twintech Heating and Cooling

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!!

by Cibele Ceroni on Twintech Heating and Cooling

Great Team! Furnace broke in the weekend, Bob visited same day and Greg installed new one on Monday. Team was professional, respectful and knowledgeable. Installation went very well, Greg found solutions to challenges, like hiding new conduits in the ceiling. Looks nice and new furnace is working great. Five Stars.

by Jackie Graham on Twintech Heating and Cooling

I used Twintech to install a new furnace for my home. Bob was terrific in explaining the sizing options and why the 2 stage furnace was the best option for me. Greg did a great job installing, clean and on time. Finished work looks great but the best part is how it works. The 2 stage heating is so much more comfortable. I run the fan continuously to keep the indoor air clean. Great investment! Would highly recommendTwintech!

by Anthony Silva on Twintech Heating and Cooling

I’m going to start this by saying I’m a very particular customer. My background is in mathematics and mechanical engineering so I have an eye for detail and a respect for technical knowledge.
Greg had already done an AC inspection and replaced a water heater tank and there was no question in my mind who to deal with replacing my rickety old furnace after it got pooched.
Bob dropped in ahead of time and clearly (and knowledgeably) outlined all technical, price and operational options.
Greg showed up on time, on the agreed date and did a fantastic job. (The OLD furnace was a house of horrors and was installed in a keystone cops sort of way- careless.)
The work Greg did was HIGHLY PROFESSIONAL and FAR MORE FUNCTIONAL than what I had.
I’m also a musician with many instruments so maintaining predictable humidity/temperature is extremely important to me. Greg recognized this as did Bob. You NEVER feel like you’re being brushed off.
In summary, if you’re looking for PROFESSIONAL, QUALITY results by an EXPERIENCED, THOUGHTFUL team
(that also happen to be FRIENDLY and ATTENTIVE ) then you’ve come to the right page!!

by Karen Morgan on Twintech Heating and Cooling

Once again Twin Tech came through and fixed my furnace. A young man by the name of Mitch came by tonight and he was so nice explained everything he was quick he was clean he turned off the lights even when he left the furnace room it’s just above and beyond Twin Tech always delivers and I just found out about them last year and I will use no one else but thanks again Mitch you are fantastic

by Richard Liu on Twintech Heating and Cooling

I had a problem with the Furnace (Armstrong ultra V) and Greg diagnosed it on the phone. Even told me what the issue was and I was able to fix it. This level of service from a Business that is almost unknown today.

If you require service, reach out to Greg. I will definitely use them in the future!
