In the midst of a heatwave, we called about our A/C being down. We were told they would do their very best to get to us the following day. At 12:20 in the day they were to come, Caleb called and asked if it was convenient for him to come. We said yes and he was there in 15 minutes. He quickly found the bad capacitor and replaced it. He also found that our refrigerant was low and added 2 pounds of R-410A.

He was very friendly and professional, worked quickly, and and made sure we were happy before he left. Even though the markup on the replacement capacitor was exorbitant, we were still pleased with the friendly, on-time service and the professionalism of the tch, Caleb.

FINALLY! If I could give them 105 stars I would. Finally a company that shows up and does exactly what they say they are going to do in the time they say their going to do it. Extremely difficult to find these days. From quote to done, 5 days. Complete HVAC replacement including new system, new ducts, and the correct size returns. First class customer service from Christian and Johnny. Stop looking, just call them. Thank you Anthony and crew. Well Done!

I've used these guys several times. Last night our AC went out so I called them first thing this morning. They had a man at our house within the hour and by noon, the AC was working again just fine. That included time they had to take to go out and get a replacement part. Tristan, the service tech, was very friendly and obviously takes his job seriously. Our unit is 16 years old and many other companies would have seized on that to try and sell me a new unit.

While they did mention that my unit has a limited life remaining, they told me it is working fine right now. There was no high pressure sales pitch, just good quality service. When I do need a new AC, you can be sure I will call these guys. I highly recommend this company.

Grissom Brother Service is an amazing company. I know nothing about heating and air. I do know my home is 15 years old and I needed a new system. Johnny at Grissom could have sold me any of the system's and some are very high. Johnny gave me the best advise and I purchased the one he suggested. BTW it was not the most expensive. I appreciate honesty when this amount of money is being spent. Anthony, Annette and Josh at Grissom are all so wonderful and extremely helpful. Thank you Grisson after going through several Heating and Air companies I am so glad I found you.
