Boiler Repair Service St. Louis

In 1904, Frank “Pappy” Fischer started installing hot water and steam boilers. What started out as a one-man business has grown into what Design Aire is today, an HVAC company with 90 employees. We were founded as a boiler company, and it’s always been a part of our business — that’s why St. Louisans trust our team of experienced and proficient boiler technicians.

Emergency Boiler Repair

Boilers are built to last for decades but there are still a number of well-known issues that may occur from time to time. If you find yourself needing emergency boiler repair service, our experts are close by. With the vast knowledge our experienced technicians have, we can help determine the problem, discuss a recommended solution that works for you and your budget, and get it taken care of right away to ensure that your boiler heating system is functioning properly.

Boilers work by delivering hot water to certain appliances in your home. Unless this water is able to reach its destination, these appliances are unable to warm up. This is usually caused by a buildup of sludge and debris or corroded pipes without boiler maintenance.

You might need boiler repair service if you experience any of the following:

  • Switches on and off – If your boiler constantly switches on and off without making any measurable change to your home’s temperature, it’s likely an issue related to the thermostat.
  • Kettling – If you hear a low rumbling sound coming from your boiler, this is known as kettling and is usually a sign of scale buildup in the heater exchange.
  • Unusual noises – Strange gurgling or whistling noises could be caused by there being too much or too little water in the system and should be evaluated by our boiler repair experts.

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.
