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!! Finally, the mini-split equipment required an electrical system/panel upgrade which Williams and their subcontractor (Add-on Electric--Jesus, Manuel and Isaac) handled seamlessly and did an impressive job of reorganizing (and labeling) several decades of obvious electrical system neglect. For anyone facing a failing heating/cooling dilemma, mini splits make significant economic and environmental sense. Our primary reservation when considering mini splits was aesthetics thinking that equipment would be obtrusive. Thankfully, within days of the installation we no longer realize they are there or operating (perk--extremely quiet system).

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.

Highly recommend this company. My water heater went out and when I called they were able to fit me in right away for a new water heater and install. The communication was excellent. They sent text messages and emails prior to my install day to remind me of my appointment time. I was not able to be home and was sending my dad to the house during the installation. I didn’t want him to sit all day waiting so at my request I asked if they could call ahead to let me know what time they were coming. They called me and also called my dad at the requested call ahead time frame which was perfect. 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 prepared with everything they needed to bring my water heater up to code. They were very professional with the installation and left everything very clean when they were done. I was very impressed with the quality of service and the quality of the water heater they installed. I will 100% use this company again.
