Williams Mechanical Heating & Air Conditioning LLC

Williams installed a mini split system for us in an old, curvy North Valley Adobe (walls generally neither square or plumb) whose venting had collapsed as originally installed under concrete slab in river bed silt. Williams was great at every step of the process in determining best heating solution given site and structural challenges: the sales process was patient, informative and consultive (Annette/Mike); the installation folks (Anthony/Alex) were friendly, professional and very conscientious with our property and animals during three day installation; when a structural challenge arose as part of the installation, an owner and field services manager quickly responded and resolved!!

Our thermostat went out during a very cold week, and we have an older home. Williams got us on the schedule quickly, and replaced the thermostat, and found one that actually fit in a narrow space on the wall. Our technician was friendly, helpful, and competent. We were very pleased with the service Williams provided and would definitely recommend them!

Updated: Still using Williams, for about seven years now. These people are honest, kind, courteous, and they always get the job done Old review: Williams is a fantastic company. We've been using them for about four years. Over that time they've installed a swamp cooler for us, handled seasonal changeovers twice a year, done plumbing repairs, and most recently they replaced our furnace. They're honest and reliable and do a great job for us. Bret is the best! He really knows what he's doing.

They showed up at the exact time of my appointment (actually a little bit early which nowadays is unheard of) and installed in the time frame that they had given. I live in an older home and they were prep

We continue to have excellent experience with Williams Mechanical. Keith McGavock solved a number of problems for us, while being very courteous, and very thorough in his explanations of how to approach our plumbing and gas line issues. We have now had big work done with Williams (new heat pump system) as well as smaller jobs (leaking sink, leaking gas line). In all cases we are very pleased with the work, and recommend them highly. I should also add that office personnel - Matt and Stephanie - are very responsive.
