      Common Air Conditioning Issues

      Signs of AC failure include:

      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

      These guys were great. Our tech, Nathan Rob, went above and beyond to give us a fair & competitive estimate, delivered timely and impeccable service... and checked in after repairs were done, to make sure everything was running good. We had a major sewer line replacement and had to deal with several different contractors. I wish I had know the possibilities of the extent of damage up front because I would have used MasterTech to complete the entire repair, instead of the multiple contractors that I used. The first contractors I used didn't have enough experience to complete the job from beginning to end and MasterTech did. Next time, they will be the first people I call.read more

      I highly recommend MasterTech based on my recent experience. I had an issue with my water heater, which is always stressful for a new homeowner.... Matt, the technician, arrived on time, was very friendly and knowledgeable, and presented me with options and information before beginning repairs. He quickly identified the issue and resolved it in about 30 minutes in the most professional manner. Can’t recommend MasterTech highly enough! Very pleased to have found this company to add to my contact sheet of high-quality local repair/service professionals!read more

      Repaired leaking water supply line outside of the house. Tech came out same day and they were able to dig up & replace entire supply line 3 days... later. Just wish it could have been quicker, but it was not a critical leak & had to schedule the backhoe and utility locationsread more

      Gary was PHENOMENAL! He was professional, kind and answered all my questions with knowledge and care. He was FAST and did a great job. I called... other places that were closer to me that never responded. I called MasterTech in Columbia and they were quick, the price was spot on AND they answered the phone! Thank you all for your hard work and dedication!David W.read more

      We got a bid to replace an outdoor spigot and fix a leaky tub faucet. The technician who came out was super nice and helpful. He answered all our... questions. The quote he gave us was $600 which we thought was way too high, so did not end up using them. I would’ve loved to use the repair service if it was more affordable,read more

      The flush mechanisms of two of my toilets needed to be repaired/replaced. We were able to replace one of the flushes, but we weren't able to repair... the second one. Max, the Mastertech plumber checked both flushing mechanisms, certified that the first one that we installed was working correctly, and made some recommendations for the second one. This morning, Max replaced the parts on the second one and confirmed that both toilets are functioning as they should. I was extremely pleased with the service, speed, and expertise with which Max completed the repairs. I highly recommend MasterTech Plumbing and will certainly use them again for any of my plumbing needs!read more

      The tech arrived on time and was very polite and respectful of my home. He found the problem quickly and did a great job of explaining to me exactly... what was going on. He also inspected and took care of some things with my heating system while he was here. The process was smooth and easy and professional.read more

      On time, always nice. They try to get you the best price. You could find cheaper but the quality will not be as good as MasterTech. I have never... had problems with them. They do emergency calls too but you will pay more.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.
