Air Conditioning Installation & Replacement

Is your A/C unit beyond repair? Are you using an outdated system that costs you more money every year that passes instead of running efficiently? Don’t wait until it’s too late to replace it!

If you have done everything you can to maintain it properly, or your older unit is costing you too much money, update it with a newer, more efficient model. Our technicians can find you a comparable, or better, air conditioning system and replace it at a competitive rate. Get a free quote on AC installation & replacement services.

Common Air Conditioning Problems

Any number of problems can happen with your air conditioning system, especially under constant use and duress in the sweltering summer months. Analyzing these problems can help you identify them and know when it is necessary to call a professional to fix them.

Below are some common problems you might encounter with an air conditioner, as well as possible solutions

Problem: A malfunctioning/blank thermostat or faulty wiring, which can prevent your AC from getting the power necessary to operate or it can cause a trip in the circuit breaker.

Solution: There are a number of variables and factors which might cause your thermostat to stop working as you’d expect. A trained HVAC technician like the ones at Design Aire can check on it and diagnose your problem at your appointment.

Problem: The A/C blower runs, but the air doesn’t cool down like it is supposed to.

Solution: You might have a contactor or capacitor problem! You can take a few steps to troubleshoot it. First, make sure your thermostat is set to your desired cooler temperatures. Next, check if you have blown a fuse or tripped a circuit breaker, as this might have happened following a power surge. If neither of these troubleshooting methods helps, or if they help only temporarily and the problem persists, it’s time to call an HVAC tech!

Problem: Low freon might indicate a leak or other problem in the refrigerant system.

Solution: A qualified technician can diagnose the problem and oftentimes fix it. However, if the problem persists or the technician finds that the unit is beyond air, we can find you a replacement one that runs more efficiently.

Problem: The outside fan stops working, and that may cause the air conditioning compressor to overheat, potentially tripping the safety overload.

Solution: Your outside fan might be blocked or needs to be cleaned. A technician can check on the condition of your A/C unit and determine the next steps once you schedule your appointment.

Problem: A frozen coil might indicate an issue with the airflow, such as a dirty air filter or obstructed return air ductwork.

Solution: A technician can check for airflow problems and determine if cleaning your ductwork or air filter will solve the problem, but they can only do that if an appointment is scheduled!

If any of these problems occur, be sure to call a professional to diagnose them and get started on the proper repairs before it gets worse.

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.
