Fast and reliable

Came home 6:00 on a Friday evening to no heat and temps in low 50. Called and came out on Saturday to fix. Had to order part and it came in when promised. Always showed up on time. Very satisfied with efficiency and price.

I had a gas leak. ONG came out to discover that I needed a plumber there ASAP to turn off the gas water heater. I called Drennen at 8 am and he was out there and got it all fixed within one hour. Thank you for the fast and reliable service.

Drennen did a full heat and air system replacement on my old home for MUCH less the other companies that quoted the same work. Everything was installed quickly and the unit works amazing.

I called Drennen mechanical after my 17 year old unit quit working.

I called Drennen mechanical after my 17 year old unit quit working. I was expecting that the unit would have to be replaced because of age. Mr. Drennen quickly diagnosed a capacitor had failed and that was all it needed. He had the part on his truck and the Air Conditioner was cooling again within minutes. HE IS AN HONEST REPAIRMAN. I WON’T EVER CALL ANYONE ELSE!!
