Martinez A/C & Heating, Inc recently came out to my home due to an issue with an element from our propane system. There was a defective element which was needed to be switched out, and so we ordered a new one for them to install. We had no problems. The company is local to our community and we have known their family forever, but this was our first time using them. They have all been very helpful, and we will absolutely use them again in the future.
