Common Air Conditioning Issues

Signs of AC failure include:

  • Strange noises or rumbling during start-up or mid-use
  • The AC unit distributes warm air rather than cold air
  • The fan is not rotating
  • A puddle is forming around the unit
  • The AC is constantly running or fails to cool appropriately

Your heating system or air conditioner can stop working when you least expect it. And we understand just how stressful that can be. It’s why we’re always available to help around the clock.

Causes and Repair Options

A wiring problem can cause your AC to stop working. Our experts will inspect your equipment and address any wiring or circuit breaker issues.

These can become damaged or worn over time (similar to tires wearing out on a car). This is usually indicated by a squealing noise. Our technicians can check for this during routine AC maintenance.

Do you hear hissing noises or notice foul smells coming from your AC? Chances are there’s a refrigerant leak. Avoid adding refrigerant on your own; an HVAC professional will know the appropriate amount to get your unit working at optimal levels again.

This is often caused by poor circulation or lack of maintenance. You will know if your evaporator coil is frozen by the warm air leaving your unit.

Your AC unit’s motor or compressor can wear out over time. After a careful inspection, we will carry out repairs or replace the defective parts.

Customer Reviews

Josh is great! He is the one who usually comes to our house. He installed an overhead tank toilet, which is a tricky and time-consuming job. He... overcame many obstacles and stuck with it until the job was completed and done right. Price was also good. MasterTech has always taken care of all our needs in a prompt and professional manner. Emergency service has always been rapid too.read more

We had to have emergency service today, Saturday. A serviceman was here in less than an hour. The repairs were made quickly, the charge was not ... over the top, even though it was not a work day, and the individual was friendly and courteous. We have learned to expect this kind of service from Master Tech. Thank you.read more

I recommend MasterTech. They show up when they tell you they will show up. They provide a comprehensive estimate and also a good explanation of the... work that need to be done. Their work is good quality. They usually have the needed parts on their truck so they can do the task in a timely manner. They clean up the work area after the job is finished,read more

A great experience. First, on time, service tech was sent out when promised. Second, quick assessment of the problem (faulty sump pump). The tech... not only quickly replaced the pump, but he made an alteration that will make it easier whenever a replacement has to be made. Bottom line, a most professional service. Certainly would recommend Master Tech to folks needing their service.read more

MasterTech is so great to work with. They're quick, clean, do great work, and have fair pricing. But the best thing about MasterTech is their people.... Whoever is responsible for their human resources does a terrific job of selecting and/or training them. They're so friendly and provide excellent information and customer service. I highly recommend MasterTech!read more

Previously I had not been impressed with master tech. However, their technician Dillon not only fixed my emergency pipe break at 1am on a holiday but... also saved me as a customer. This was the best service I have ever had at my home. He arrived promptly at 1am. Provided a couple of options on how to fix my problem both in the short and long term and quickly made repairs. He also has provided advice on how to address issues related to the water damage caused by the busted pipe. This was one of the most positive bad situation we have had as homeowners. Thank you Dillon and mastertech.read more

I had to change my appointment at the last minute and they were able to accommodate my new availability without any hesitation. My tech was really... professional (Dillion). I got a call and a text to let me know he was on the way. He fixed my problem quickly and was so friendly. This is the second time that I have had to use a plumber and I will use Master Tech again since I have an old house with old plumbing.read more

Timely AC Replacement Can Reduce Maintenance Costs

The decision to replace your air conditioner isn’t always easy. It’s a significant investment. This is why we always do our best to provide our customers with more cost-effective repairs when possible.

However, if your older AC unit is on its last legs and showing signs of failure, replacing it will offer more long-term advantages. A new air conditioner can help you enjoy lower energy bills, provide superior airflow, and leave you with greater peace of mind.
