I have not yet utilized their services, but I was in need of parts for my HVAC unit, which they unfortunately didn't have on hand. They didn't hesitate to tell me where to go to purchase the blower motor I was in need of. This kind of assistance, in the face of not making a sale with me, has put this company on the radar for future service work when it arises! Thank you William Brockman & Sons for you assistance today, you are a standup company!

I pride myself on fixing things myself. After a judicious googling of the issues, i was able to diagnose the issue in my furnace myself (bad hot surface igniter), I called in to see if they had the part. Fred was very helpful in determining the broken igniter was already an aftermarket on my 20yo furance but said if I came in he could help me find on in stock that would work.
I went in and Fred immediately determined which one i had, and had a new replacement ready to go. He even took the igniter off of the bracket and put the new one on for me.
They very well may have earned my loyalty based

Brockman and Sons replaced an old furnace. The new furnace is upgraded and more efficient. They also found problems around the old system and fixed them.
They were on time and the price stayed the same even though they did extra repair work. They also review the thermostats and made sure they were working properly.
Excellent service. Trustworthy!

Brockman and Sons continues to distinguish itself as the best HVAC company in the Dayton area. The company's owner, George Brockman, is an outstanding individual who deeply cares about the customer. Most recently, we had a mini-split installed in our backroom. George took the time to come out and answer all our questions (we had a lot) prior to installation. Installers Dave and Jordan did great work ensuring the system was working properly and addressing questions we had along the way. I highly recommend Brockman and Sons to anyone seeking work related to HVAC in their home-they are professional

Simple and Affordable: I was able to go in the store and buy a $24 AC capacitor without an account or paying for installation (like many HVAC businesses). There was no sales pressure. The guy working there confirmed my old capacitor was bad (it was bulging) and said the new one has a one year warranty. This is a great deal!
Update: I had a 27 year old 80% efficient 100k BTU furnace having trouble lighting up. Brockman helped me try to keep it running with parts, but I got tired of messing with it. Brockman installed a 95% efficient 40k BTU Lennox for $2500. I specifically requested the 40k. The
