Homeowners are likely to encounter issues with their air conditioning systems at some point. To ensure that an air conditioning problem doesn’t develop into something more serious, it’s important to be able to properly identify and address the issue. As always, the HVAC experts at Design Aire can help you with your AC service needs should any of these problems arise.

Moisture Buildup

Although moisture typically accumulates in functioning air conditioners as a normal part of the cooling process, too much moisture can indicate leakage or cause mold to grow. Oftentimes, excess moisture indicates that you’ll need to replace your entire unit.

Cold Air Isn’t Blowing

If your air conditioner ceases to blow cold air, this is one of the earliest signs that the unit is in its final days. Our air conditioning repair techs may be able to help resolve the issue by taking certain steps such as unclogging drains, but oftentimes a complete replacement is needed.

Bad Smells from AC

Air conditioners should produce odorless cold air. If you notice any strange smells coming from your air conditioner, you may be able to get rid of them through a simple fix. However, bad smells could also be indicative of a serious underlying issue. Reliable air conditioning services will be able to pinpoint the problem and provide the right fix.

Odd Noises

Air conditioning units should be relatively quiet, so any squealing, squeaking, or grinding sounds could hint at a serious problem. It’s often best to consult with our technicians to diagnose the root cause.

Increasing Energy Bills

Rising energy expenses during the summer can be alarming, and they may result from an inefficient air conditioning system. If you notice that your bills keep increasing each summer, you may need to consider getting a replacement.

Faulty Wiring or Thermostat

If your thermostat is blank or isn’t working or wiring within your AC system is faulty, your unit may not get the power it needs for optimal functionality, or it can result in a tripped circuit breaker. A Design Aire technician can help determine if either is a problem.

Failing Fans

If the outside fan in the AC unit isn’t working the way it should, the unit’s compressor could overheat. A nonfunctioning fan normally indicates that cleaning is in order, as dirt, parts from nearby plants, and other debris can get into the unit and block the fan or make it dirty.

Low Freon Levels

A decrease in freon levels could indicate certain problems such as leakage, but it can be difficult to identify the specific issue. In some cases, you may need to replace the entire unit if you can’t maintain a consistent freon level.

Frozen Coil

Any coils in the unit that are frozen could be signs of an airflow problem, which may include blockage of the return air ductwork or a filthy air filter. We can examine the unit to determine if there are any airflow issues and the cause behind them.

The installation team arrived on time and went right to work.They worked with confidence and professionalism.We appreciated the care in protecting our floors and even the choice of how they went up on the roof indicated that they really did care. This company did what they said they would and certainly has our vote of appreciation and gratitude. We will happily recommend Design Aire to anyone.

One of the best companies to work with. My own profession is in a service industry and so I very much appreciate all the positive things about Design Aire.
The install crew arrived right on time and took exactly how much time they said they would to complete the job. The work was done well, the crew cleaned up after themselves, and were very pleasant. Seth in the office was extremely in-tune to our needs and very responsive.
I would highly recommend Design Aire.

Our new HVAC system was installed yesterday and we could not be happier. From quote to completion the process was great! 100% would recommend!

We have used Design Aire for both a new furnace two years ago and a new AC unit this summer. Everything was done very professionally and quickly. I would not hesitate to recommend them to anyone needing any type of HVAC work done.

We've used them for our old house and our new house. They are honest, friendly, professional and affordable. We felt lucky to find them.

Maddy R.

I was very impressed with Design Aire. They were timely and did an outstanding job with the installation of my new furnace. They had great communication and went above and beyond. I would highly recommend them to friends and family. Thank you so much Seth and Design Aire for making this an effortless transaction. VERY PLEASED!

Jonny M.

Design Aire sent a salesman to plan the system, and just a couple of days later sent the installers to remove the old system and install the new one. Everything happened when they said it would and the system performs as they said it would. All of the Design Aire staff were courteous, the work was performed efficiently and neatly, and they left the area cleaner than they found it. This is the second unit Design Aire has installed for us, and I have no need to look elsewhere.
