Realized my furnace stopped working late last night and forecast called for very cold arctic air blast. Called my regular HVAC company that advertises 24 hour service to find that after 7 PM, there is only an answering service. Same with two more “24 hour service” companies. Then I called Thomas Hoffmann HVAC Company and Nick quickly answered, listened to my issue, gave me a quote and was on his way. Nick arrived soon, completely checked out my furnace, found the problem and did the repair. Because the problem was fairly minor, he even gave me an unexpected and very appreciated discount. Nick was professional, competent, and very engaging. Best emergency, after-hours experience I’ve ever had. Nick saved the day and gave me the peace of mind I needed.
Response from the owner: Thank you, Richard, for sharing your experience; we're glad Nick could provide you with prompt and professional service during such a challenging time. Your kind words mean a lot to us!

Furnace would not blow heat on Friday night and after leaving a few messages to several companies, Mr Hoffman called me back quickly and did a service call. Diagnosed the issue and was able to fix the problem. Will need a new unit soon, but nice not be without heat during the holidays! Quote and Invoice receipt done on the spot and detailed! Will use again for sure.
Response from the owner: Thank you, Heath, for your kind words! We're glad Mr. Hoffmann could get your furnace working in time for the holidays and provide a detailed quote and invoice. We appreciate your trust in us and look forward to helping you again in the future!

I was referred via home advisors. And I was so worried about the cost and the distance but Nick came and found my problem and fixed my problem and if I could I would shout-out to the world this is a honest and good company to hire. As a landlord over the road of 5 homes. I can call this company and trust that they will do the job and be honest. And I will not have to pay extra fees or be given a 3 week appointment Just because it's rental property. This is my go to company and I strongly recommend this company.
Response from the owner: Thank you, Annie, for your wonderful feedback! We're so glad to hear that Nick was able to address your concerns and provide you with the honest service you deserve. Your trust means the world to us, and we appreciate your strong recommendation!

If you are a business owner or building manager and are in the process of purchasing a new HVAC system for your facility, many factors are essential to consider. One critical factor is the size of the unit you choose.
Tips for Choosing the Right Size HVAC System
When it comes to replacing your commercial HVAC system, it’s important to remember that bigger isn’t necessarily better. An oversized unit will consume more energy than necessary while also producing excessive indoor humidity. On the other hand, an HVAC system that is too small won’t cool or heat the building adequately.
It makes sense, but how do you determine the correct size? After all, there are numerous cooling and heating systems out there, which makes the decision-making process intimidating for some business owners. Choosing the right HVAC system for your commercial property requires the assistance of a professional commercial HVAC company.
Some tips and facts to keep in mind include:
- Air conditioning units are generally rated in tons, with the sizes available increasing in ½-ton increments. The average commercial HVAC system size is around two tons for small buildings but can be as much as 30 tons for larger systems.
- Professional HVAC experts will calculate your building’s cooling load in BTU, or British Thermal Units, to select the proper heating and air conditioning installation size.
- It generally takes approximately 25 BTU to heat/cool one square foot, and that one-ton unit can heat/cool around 12,000 BTU per hour. Other factors can also affect your cooling loads, such as your building’s design and weatherization.
