Thankfully Belo was able to walk me thru some trouble shooting and we have it running for the night so I can just schedule a regular service call for tomorrow! I never thought I'd see the day when a service provider would spend 10 minutes on the phone with a customer to avoid charging them an emergency service fee! I spoke with a gentleman named Mark and he was so helpful! My parents have also used them for a long time. (See More)

The BELOMAN Team were once again great in keeping me informed ahead of time when our technician Mark had gotten tied up longer than expected on his current job.
We rescheduled at my convenience for the next day.
Mark arrived on time and jumped right in on our winter check up, cleaned inspected everything and answered all my questions.
I am very happy with the all service he has performed for us over the last two decades and would highly recommend Belo to anyone needing any HVAC service. Great Job as always. Thank you so much for the great service and trouble free years of uninterrupted service.

We called out Beloman for a faulty A-coil in our air conditioner... We had numerous problems in the past with this unit but it was not serviced by Beloman before. Prompt service....they honored the warranty on the product and gave us full disclosure on the new product. (See More)

He is absolutely professional helpful and you can tell he is concerned about any issue we have. As far as I’m concerned, he does the best service and I think he should be commended since he always goes out of his way to assist us. I have a boiler so I can’t have just any random technician out. I need someone that knows his stuff and that’s what Mark does. He always treats me and my wife fair and shoots us straight when it comes to warranties. We really appreciate his professionalism.

My furnace stopped working at 10:30pm when it was below freezing outside. After calling Beloman, Mark G. returned my call very quickly and helped me trouble shoot what might be wrong over the phone. When we couldn't get the furnace started he had a Beloman representative call me the next morning and schedule Nick K. to come out. Mark G even followed up the next morning to check on everything. Nick K. was able to solve the problem order a new part and did the repair the next day. The responsiveness of Beloman and professionalism of Nick K. were amazing. I signed up for the maintenance service and am very happy with this company. Mark G and Nick K both deserve a bonus! Thank you so much. (See More)

Mark arrived at his scheduled time, and did a very thorough job with the scheduled maintenance on our Furnace. Mark was very courteous and thorough. The dispatch team also went above and beyond the call of duty by getting hold of Mark for me, just before his scheduled arrival, to let him know I would be a little late getting home from an errand I was running. And so, when Mark arrived, he knew exactly what was going on. I will continue to choose Bel-O for our heating and air conditioning needs, because of their great work! (See More)

I highly would recommend Belo to anyone needing HVAC work. From the office staff to the technicians I have felt with all were very professional and helpful.
Mark has been worked for my parents prior to doing our service work. In all probably about 20 plus year of servicing our family. He has always been on time very need and through in his work. I feel very comfortable with him doing our service.
He is a true asset to your company.
Regards, Bob & Margaret. (See More)

A note of great appreciation for Mark Gass at Bel-o,
I started work at Althoff 3 years ago this coming August. I had experience in residential maintenance but had never worked on such a large building before. I was painfully unfamiliar with many of the systems and I would have never been hired as director of maintenance if it weren’t for the other skills on my resume. Principle Harris told me there would be a learning curve and if I needed help I should just call Mark Gass at Bel-o he’s the best. So I did and since that first call I have come to rely on, trust and admire Mark. He is amazing!!! There is nothing he can’t fix. His level of knowledge and skill is more than impressive. He has gone so fall above and beyond the call of duty helping me to understand how this building works and learn what I needed to know that I will never be able to repay him. Mark is a really great guy, kind hearted, gifted and fun to work with. Mark is fast, and efficient, honest, considerate, punctual and reliable. He always does what he says he is going to do when he says he will do it and acts in our best interest, “that is ethics & characterâ€. He makes me want to intentionally break something just to have an excuse to call him for help. He makes hard work look easy and NEVER complains! I have learned so much from Mark and that has given me the confidence and knowledge I needed to manage this building. It gives me a great sense of security knowing he is just a phone call away. Bel-o has always done great work for us but it is because of people like Mark that I will be a loyal customers for life. I get companies calling me all the time to try and get our business but I tell them I’m not interested because I have everything I need thanks to Mark. I owe him! Thank You Mark!!! You have become a true friend and I/we appreciate all you do and all you have done for us more than you will ever know.

We have used Bel-O for heating/cooling, plumbing and pest control at Westfield Manor for 12 years. They are very helpful and answer calls quickly.

This is from Mike Justus - I have known Mark G. professionally for at least 20 yrs. He has kept the plant running with his expertise in air conditioning and heating. Troubleshooting on various other problems that we have had in the past and keeping all the critical systems running and up to date, I would not hesitate to call him for help. - Thank you (See More)
