      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

      MasterTech does all of our plumbing and HVAC work and has for years because they always do a great job. Most recently, we had a horribly clogged... toilet that we could not fix ourselves; they took care of that and checked other issues as long as they were at the house. All of their people are excellent and we always know we can count on them.read more

      Gary Buck was amazing! He arrived on time, identified the leak, and saved me money. Most importantly, he repaired the leak in about 2 hours as... promised. He was personable and professional. He explained the process and the warranty. Gary was helpful and honest about the repair. He even offered a suggestion and left an opportunity for a future addition. I will use Gary's services again! Thank you Master Tech Plumbing, Heating, and Cooling.read more

      We own a home built in 1880. The sewer problem was located beneath a brick fireplace a few feet away from the city alley. It would have been easier... to dig in from the alley, but it would have doubled the repair cost! The tech team (Nathan,Chris,and Fletcher) were determined to keep out of the alley and save us the extra expense!Upon toppling the fireplace they discovered it was resting upon a 5’x5’x28” cube (or larger) of concrete that would not budgeOn day 2 they began work around 9 am. It took nearly 3 hours of jackhammering to finally break the monstrosity apart and gain access to the collapsed pipe below.By 3 pm the sewer line was repaired!!! Way to go, Fletcher!!These guys deserve every dollar it cost us! They were ever so patient as I hovered over them the entire time photo-journaling their work! Can’t praise this team enough!!read more

      So far I haven't used Master Tech to install or service anything, but I plan to. Gary came out to assess and give me an estimate on water heater... options. He was great! He was informative and not pushy. He was very knowledgeable and talked out the options with me and answered all of my questions and then some.read more

      Update to my original review - these guys are the best; I worked with Matt, Chris and Nate on a variety of issues from sewer line, to HVAC all around... the holidays when timing can be tough. They did it all very quickly with a ton of knowledge and were very kind. Their service convinced me to become a paying member for the yearly inspections/service and peace of mind. Highly recommend.read more

      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
