Signs Your Air Conditioner Needs to be Replaced

The air has stopped blowing. 

One of the first signs that your air conditioner’s days are numbered is that it will stop blowing cold air. We’re always happy when we can resolve this problem in a simple way—such as clearing a clogged drain—but many times, this problem signals a need for a full replacement. Our trusted Design Aire technicians will inspect your unit and let you know your best course of action.

Moisture is building up.

Moisture is a normal part of air conditioner function, but excess moisture from a refrigerant leak, or moisture that leads to mold growth is not normal. It may be an indication that your AC is beyond repair. 

Your AC is making strange noises.

If your AC is squeaking, grinding, or squealing, it may be a sign that something serious has gone awry. There are many reasons why this could be happening, and our expert technicians will exhaust those possibilities before making a recommendation to replace your air conditioner.

Your air conditioner smells bad.

The air coming from your air conditioning system should not have an odor. When it does, it may require a simple fix, but it could be a sign that something serious is happening. Design Aire’s AC repair service technicians will provide an honest assessment of what steps need to be taken next.

Your bills keep going up.

If your energy bills are on the rise from summer month to summer month, or year over year, it very well could be that your air conditioner is no longer running as efficiently as it should. It may be time to replace it with a more effective, energy-efficient cooling system.

Customer Testimonials

Seth was our salesperson. He listened to our needs and provided the right product at the right price. 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.

Ken L.

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.

Heather H.

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

Greg H.

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.

Sean K.

Design Aire was the best choice from start to finish. Design Aire gave me the best price with the most detailed quote. The service technicians were very friendly and completed the job ahead of time. I highly recommend Design Aire.

John K.

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.
