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.

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.

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.

⭐️⭐️⭐️⭐️⭐️ If I could give 10 stars, I absolutely would.

Last night our furnace went out unexpectedly, and with three kids in the house, the temperature dropped fast. Giovanni went above and beyond in every way possible. Instead of charging me a late-night service fee, he simply asked, “Are you decently handy?” and offered to walk me through some troubleshooting steps to get our heat back on so my children wouldn’t have to sleep in the cold.

Not only did he guide me through the process, he even FaceTimed me and showed me exactly what to take apart, how to put it back together, and what signals to watch for. It felt like having a real technician standing right next to me the entire time. Thanks to him, our heat was restored within minutes.

In a world where true customer service is hard to come by, Giovanni is a rare find. It is a guaranteed fact that any future repairs, maintenance, and the new heater/AC system we’ll be needing this coming summer/fall will absolutely be done through him. His honesty, kindness, and expertise have earned our business for life.

Highly, highly recommend.

Response from the owner:Thank you, Jeff, for sharing your experience! We're so glad to hear Giovanni was able to help you and your family during that tough situation. Your recommendation means a lot to us, and we appreciate your trust in our services for the future!

I called this company earlier today because I was having a bunch of issues with my HVAC system. They were incredibly friendly and walked me through troubleshooting step by step over the phone.

Really grateful for their help and would definitely recommend them if you want straightforward and trustworthy service. Five stars all the way!

Signs Your Boiler Needs to Be Replaced

Boilers are a popular heating system in the U.S. They last long and deliver efficient and comfortable heating to a home or business. Thomas Hoffmann Air Conditioning & Heating provides complete boiler replacement for many types of boiler systems. Whether you have a hot water radiator or a hydronic floor system, our experts can help you decide when to replace your boiler. Some of the signs that your system needs to be replaced include:

• Age – When properly installed and maintained, a boiler can last 20 years or more. If it’s older and has started to require frequent repairs, it’s likely time to replace it. If it just continues to break down, the cost and time associated with fixing it don’t make much sense.
• Water leaks – A boiler uses a lot of water and will likely begin to leak at some point. These issues can be repaired, but they may indicate that it’s time to replace your boiler system.
• Strange noises – If your boiler system begins to make strange noises, it’s time to get it looked at. Some noises may mean your boiler needs to be repaired, while others might indicate more serious issues.
