When I bought my house another company had been servicing my boiler so I stuck with them. Last year, they told me a problem with the boiler meant I needed a whole new system. Quoted me $10K. I called Brown Hearing & A/C for a second opinion. I did not need a new boiler and the fix was incredibly simple and quick. My same boiler has lasted through the entire winter with no further problems. The technician who showed up took extra time to explain everything to me. Top rating for being quick, polite, honest with me and not trying to charge extra. Definitely go with them.

I had Brown Heating and AC install central air at our previous residence and they installed it a day early and in very timely manner. Had them check over the furnace at our new residence before winter and were very prompt, called ahead, and fixed our issue at a very reasonable price. Have been recommending Brown HVAC to anyone I know that is looking for someone in this trade, and they have been very happy too. Highly recommend.

They came out in the middle of a tornado warning this morning after I called after hours last night. (no A/C in 80-90 degrees in here) to make sure we were comfortable. Amazing service. Even dealt with kids, pets, rain, lightning….never complained once. Love this company! Thank you SO very much.

My husband and I built a new home. We chose Brown Heating & AC Inc and were very pleased. We kept their office staff updated on our other contractors progress and Brown’s crew were there the day we needed them to start. The crew was professional, all wearing branded shirts, and cleaned up the area after the work was completed. We highly recommend them!

Great service at a fair price! I called them Wednesday afternoon and they were able to fix a problem for my small commercial building Thursday morning. They were able squeeze me in at a time when they were busy. The tech had the parts with him to fix it right away. Thanks!

Our air had gone out sometime during the night. I called at 7:20am and Brown could have a technician at the house by 8. Their technician was on time and very friendly. He had our AC working within a half an hour. This is the first time I had to have the AC serviced, but if anything goes wrong again I’m definitely calling them again!
