0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.
Response from the owner:Hi there. I am unable to locate your customer profile. Please give our office a call at 314-471-7625 so we can get this figured out for you.

I will always call Hoffmans for my air and heat needs. They were out to my daughters house that day and fixed it. It was right before the weekend storm with below zero temps the next day. They saved my daughter and grandbabies. I could never thank them more.
Response from the owner:We are so happy to hear that we could help! Thank you for the kind review.

Got a quote over the phone. Everything was explained thoroughly. Dakota, my technician arrived and on time, was very professional and knowledgeable. He didn’t try to upsell or change anything. He did a great job. We can already tell the difference since the ducts and vents were cleaned. Would recommend an use Hoffman again in the future.
Response from the owner:Happy to hear you had a pleasant experience using Thomas Hoffmann!
The technician, Ryan, was knowledgeable and helpful in identifying the issue with our mini split AC unit. They are the second company we called after issues with the first and will be using Hoffmann again.

Response from the owner:We are so happy to hear you had a great experience, Sam! Thank you for the review, and thank you for your business.
Your service technician was very professional and knowledgeable. And did not appear to try to give me bogus information. I truly appreciate his honesty because several other companies did not appear to be honest, obviously wasn’t honest, my gut feeling told me they were not honest and tried to get me to spend $10,000 for a problem that was much simpler to fix. I look forward to you servicing all my properties, and possibly those of the rest of my family.
Response from the owner:Thank you so much for the kind words and great review! We appreciate your support.
Trane Systems We Install in St. Louis
We install a full range of Trane residential HVAC equipment, including:
Trane central air conditioners — XR, XL, and XV series including high-efficiency variable-speed models. See our AC installation St. Louis page for more.
Trane gas furnaces — XC, S9X2, S8X1, and XB series for reliable, efficient St. Louis heating. See our furnace installation page for details.
Trane heat pumps — an efficient all-electric heating and cooling option for qualifying homes. See our heat pump page.
Trane air handlers — matched system components for optimal performance and efficiency
Why Proper Installation Matters as Much as the Equipment
A high-efficiency Trane system will not perform as designed if it is improperly sized or poorly installed. Common installation mistakes — oversized equipment, undersized ductwork, poor refrigerant charging, incorrect airflow setup — can reduce efficiency, shorten system life, and leave your home uncomfortable even with brand-new equipment.
At Thomas Hoffmann Air Conditioning & Heating, we size systems correctly for your home, ensure proper refrigerant charge, and verify airflow before we leave. We do not cut corners because we are the ones who will be servicing your system for years to come — including any Trane AC repair or Trane furnace repair down the road.
When to Replace Your HVAC System with a Trane
Your current system is 15 years old or older and facing a major repair
Your energy bills have increased significantly without a change in usage
You are calling for repairs more than once per season
Your home is never quite comfortable even when the system is running
Your current system uses R-22 refrigerant, which is no longer produced
Frequently Asked Questions — Trane Installation in St. Louis
Most standard residential replacements — a furnace, air conditioner, or both — are completed in one day. More complex installations involving ductwork modifications or zoning systems may take longer. We will give you a clear timeline before we start.
Yes. Trane equipment comes with a manufacturer's limited warranty. Many Trane systems offer 10-year parts warranties when registered. We will walk you through the warranty details specific to the equipment you choose.
You can replace either unit independently. However, if one component is significantly older than the other, we may recommend replacing both to ensure system compatibility and efficiency. We will give you a clear picture of the tradeoffs so you can make the right decision.
Trane is consistently ranked among the most reliable HVAC brands and holds up well in demanding climates like St. Louis, where systems work hard both summer and winter. Whether Trane is the right fit for your budget is something we are happy to discuss honestly — without pressure.
