Jason Ornburn
McCullough Heating team was great and I would highly recommend them for all HVAC installs. I was able to call them on a Tuesday, have them out by Wednesday to go over all different bids and types of systems and begin/finish the install on Thursday. When there was an issue after the install due to unknown residual damage from the Round Rock hail storm their team, specifically manager Jensen was out within an hour (during after hours) to diagnose and address the issue. Great team all around and I'm very happy with my new system.

I am so thankful to Mathew w/ McCullough arriving at my home this morning on time and assuring me my furnace is fixable and will not break the bank. I called McCullough at 7AM this morning and Mathew was at my home by 9:10 AM.
