“I was originally drawn to Union Heating And Air Conditioning because they are veteran-owned.”
I was originally drawn to Union Heating And Air Conditioning because they are veteran-owned. The fact that they don't have an minimum diagnostic fee or visit fee and didn't require two separate appointments sweetened the deal. The owner, Samuel came out to do the work himself. He was prompt, friendly, productive, and effective. Our issue was resolved by the time our appointment was scheduled to start.

“I had asked for an estimate and they sent Samuel over.”
I had asked for an estimate and they sent Samuel over. He was polite and professional. He even removed his shoes when coming in my house. I felt like he took the time to elaborate how a new furnace would save me money on my energy bill. I will surely recommend Union Heating And Air Conditioning now and forever!!
