Richard L.

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!

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!

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 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.
