We have used Thomas Hoffman Air Conditioning and Heating for AC issues for the last two years. We have been so happy with the service we have received both times. This year, we just needed a little maintenance as our unit wasn’t working to its full potential. I called first thing in the morning and was able to get a same day appointment! Nick was so personable and knowledgeable, and he got us back up and running and no time. Thank you again for saving us from the summer heat!! We are so grateful for the amazing customer service you guys provide!!!

Vicki C.

I txt Thomas Hoffman air-conditioning and heating Sunday early evening about 6:30 and just left A detailed message of what was going on with my AC I received an automated reply, saying they would contact me soon. I heard from them the next Morning at 11 AM to confirm what was going on with my unit and said they would have a Tech out today still but would be the last call between 6 and 8pm. I expected to get an appointment 2 to 3 days later. We’re in the middle of about an 8 to 10 day Heat wave of Mid to upper 90s. So imagine my surprise when I received a call from Zachary at 3:20 telling me he was in Saint Charles and was on his way to my house to look at the unit. When I explained what was wrong on the phone, he was pretty confident. He knew what it was once he got here, pulled off the cover and sure enough it was the capacitor. Pull the old one off and install the new one turned it back on and boom I have cold air blowing. I would highly recommend Thomas Hoffman, AC and heating and if you can request a certain Tech Zachary is your guy he is great super Frndly got the job done quickly and even interacted with my dogs Who are super friendly

Response from the owner:Thank you, Vicki, for sharing your experience with us! We're glad to hear that Zachary was able to resolve your AC issue quickly and that he made a positive impression on both you and your dogs. We truly appreciate your recommendation and look forward to assisting you again!

Morgan S.

We can’t say how happy we are with the quick and efficient service! We came home Friday evening after work on a 95 degree day (with a week of 90 degree weather ahead) and our A/C was totally out. We called this small business owner around 6pm and he was here by 7:25. He replaced our wires, had cool air running, gave us some helpful tips for the future, and was already out the door by 7:50. He was very polite, friendly, straightforward, and saved our evening/weekend!

Response from the owner:Thank you, Morgan, for your wonderful feedback! We're glad our team could provide quick and efficient service to keep you comfortable during the heat. Your satisfaction means a lot to us!

ImfamousDante

They were timely, polite, professional and they saved us from too much sweating. In a field full of pompous and arrogant technicians, these guys take the time to explain what is wrong and how they are correcting it. Other folks just assume you are incompetent but these folks take the time to educate. Cannot recommend highly enough.

Response from the owner:Thank you for your kind words! We truly appreciate your feedback and are glad we could provide you with a positive experience.

W M.

Great service and arrived on time when promised.

Here are 6 reasons why furnace maintenance and repair should be entrusted to experienced professionals.

1. Safety First: One of the primary reasons to hire a professional for furnace maintenance and repair is safety. Furnaces involve complex systems and potentially dangerous components such as gas lines and electrical connections. A trained technician has the knowledge and expertise to handle these elements safely, reducing the risk of accidents, gas leaks, or electrical hazards.
2. Proper Diagnosis: Furnace issues can be caused by various factors, ranging from mechanical failures to electrical problems. Attempting to diagnose and fix these issues without the appropriate knowledge can lead to misdiagnosis and further damage. Professional technicians undergo extensive training, allowing them to accurately identify the root cause of the problem and implement effective solutions.
3. Efficiency and Performance: Regular maintenance by a professional ensures that your furnace operates optimally. A well-maintained furnace performs better and consumes less energy, lowering utility bills. Professional technicians have the skills to clean and fine-tune the various components of your furnace, enhancing its overall performance and longevity.
4. Extending the Lifespan of Your Furnace: Investing in professional maintenance can significantly extend the lifespan of your furnace. Regular inspections and tune-ups can prevent minor issues from turning into significant problems, ultimately saving you money on costly furnace repairs or premature replacements. A well-maintained furnace is more likely to provide reliable heating for years to come.
5. Warranty Protection: Many furnaces have manufacturer warranties requiring regular professional maintenance. Failing to adhere to these maintenance requirements may void the warranty. Hiring a professional ensures that your furnace is maintained according to the manufacturer’s specifications, protects your warranty, and potentially saves you money on future repairs or replacements.
6. Compliance with Local Codes and Regulations: Furnace installations and repairs are subject to local building codes and regulations. Professional technicians are well-versed in these standards, ensuring the work complies with safety and environmental guidelines. Hiring a professional guarantees that your furnace operates within the legal framework, avoiding potential fines or legal issues.
